Written by fertilizer production line on December 7th, 2019.

The rotary drum granulator machine is designed for producing the organic fertilizer granulator or inorganic fertilizer granulator.How can we use the rotary drum granulator machine to finish the fertilizer production process?

Different type fertilizer granulator machine are designed for producing the organic or inorganic fertilizer granulator.Different type fertilizer granulator machine has different working principle.The rotary drum granulator machine is designed for producing the organic or inorganic fertilizer granulator.There we share the principle of the working principle with you.
The drum granulation is a method of mixing and granulating powdery basic fertilizer with drum granulator,which is widely used in the granulation of compound fertilizer.The series of rotary drum granulator machine is designed for not only used in the compound fertilizer manufacturing process,it also can be used in the organic fertilizer manufacturing process to produce the organic fertilizer granulator.

The principle of the rotary drum granulator:First of all,the basic fertilizers are screened separatedly,and the screened materials are crushed by the crusher before screening.The material under the screen is sent to the respective hopper.When the pelletilizing system is in operation,each basic fertilizer is fed into the feed hopper through the metering equipment,conveying equipment and lifting equipment according to the proprtion requirements from each hopper at the same.At the same time,the return material also enters the hopper together with the basic fertilizer through the lifting equipment.There is a certain degree of mixing between the basic fertilizer and the returned material in the process of transportation and lifting,but it is more ideal to add a mixing equipment.The mixture in the feed hopper is fed to the rotary drum granulator at a certain feeding speed.At the same time,in the fertilizer manufacturing process,saturated steam is properly introduced into the bottom of the material layer,which not only improves the temperature of the material,but also makes the material wetted,which is conducive to granulation.If necessary,sprinkle a small amount of water or fertilizer solution on the material to maintain the best liquid volume of material granulation.The material forms a rolling bed by the friction action of the rotary drum granulator.The extrusion pressure generated by the rolling makes the material with certain liquid phase agglomerate into small particles.These small particles become the core,and the surrounding powder adheres to form large particles.As the drum granulator generally inclines to the discharge end at a certain angle,the granular material slowly rolls to the discharge port along the inclined direction of the cylinder while rotating with the cylinder.Qualified particles leave the drum granulator and enter the dryer for drying,and then pass through screening,cooling,coating,packaging and storage.After crushing,the upper part of the screen and the loweer part of the screen will be sent to the hopper as the return material and the basic fertilizer will be granulated at the same time.In the granulating process,we are besides the granulating method to be used to produce the fertilizer granulator,there is also designed the flat die granulator machine and the roller press granulator machine which are suitable for using the extrusion method to produce the fertilizer granulator.

How to improve the pelletizing rate of NPK fertilizer production

Written by fertilizer production line on December 3rd, 2019.

NPK compound fertilizer is characterized by simple composition, high nutrient content, low dosage, quick fertilizer effect, convenient application, transportation and storage, and rapid improvement of yield and quality. In order to produce large quantities of high-quality compound fertilizer, the first step is to produce good fertilizer granules.

The main factors influencing NPK fertilizer production line are as follows:

Production equipment;
Process technology;
Physical and chemical properties of raw materials;
Production formula and added conditioner;
Air temperature and air volume at the outlet of the dryer;
Temperature and liquid phase quantity of granulating materials;
Material flow;
Material return ratio;
Quality of operators;
Climatic conditions.

Only by integrating the above factors into making fertilizer granules, can we produce NPK fertilizer with high yield and good quality, one of which is indispensable.

NPK fertilizer production line

1. Improving the performance of NPK fertilizer production equipment is the basis

Choose qualified production equipment, choose well-equipped, complete test means, reliable product quality manufacturers, under the guidance of experienced personnel to buy, late equipment management and maintenance personnel to have a certain professional level. Zhengzhou Huaqiang Co.Ltd are leading agricultural fertilizer machine manufacturer in China. We has strong technical strength in fertilizer machines. All of our products comply with international quality standards and greatly appreciated in a variety of different markets throught the world.

2. Choosing ammonium phosphate with good viscosity as raw material is the premise

The pelletization of NPK fertilizer mainly depends on the viscosity of ammonium phosphate and conditioner, and the poor viscosity of ammonium phosphate directly affects the pelletization rate of compound fertilizer. Therefore, when purchasing ammonium phosphate, we should consider not only nutrient content and price, but also its viscosity. From the actual production experience, the viscosity of diammonium phosphate is better than that of monoammonium phosphate.

3. Ensuring the fineness of raw materials and feedbacks is essential

The finer the powder of the raw material, the better the viscosity of the material, the more important it is to improve the efficiency of the crusher

Chain crusher to help make the big granules into the fine powder and get back to fertilizer granulator machine. It is simple and compact in structure, cover small area, easy maintenance such characters, crushing effect is good, smooth operation, easy to clean.

4. Material mixing is an important measure to improve the NPK fertilizer production line efficiency

The material is mixed evenly, on the one hand, the mixer mixes the fresh material evenly, on the other hand, the mixer combines the returned material and the fresh material evenly. Because the fine powder in the returned material is mostly potassium and nitrogen with poor viscosity, it is the material that is least likely to form into a ball, while the fresh material has better viscosity and is easy to form into a large ball in production. Mix the two thoroughly to prevent the formation of large balls and too much powder.

5. Suitable moisture and pelletizing temperature are the key

Only when the temperature and water content of granulating materials are adjusted to the optimal point can the granulation area be ensured to be normal.

The disc fertilizer granulator is suitable for the production with small yield, and the rotary drum granulator is suitable for the mass production of NPK fertilizer. Addition of moisture during granulation requires certain experience of operators.

6. Suitable air volume and stable furnace temperature are the preconditions

The size of the air volume directly affects the drying effect, the air volume in the dryer, the drying effect is good. If the air volume is too large, it is easy to extract the powder in the simplified body, and the wind speed should be less than 2m/s. Best cooling head end temperature difference is about 100℃, the import and export temperature cannot frequent adjustment. When urea is used as nitrogen source, the temperature should be determined according to the amount of urea. The more urea is used, the lower the drying operation temperature will be.

How to Preventing Caking from the NPK Fertilizer Production Process

Written by fertilizer production line on December 3rd, 2019.

NPK compound fertilizer is prone to cake because of its strength, moisture content, storage and so on. This article will introduce how to prevent caking from the process operation of NPK fertilizer production process.

NPK fertilizer production equipment produce products with smooth and uniform particles

Non-uniform particles, too many fine particles, non-smooth fertilizer, the compressive resistance, wear resistance is also poor, easy to be compressed and deformed in storage and transportation. The contact area between particles increase, which is easy to agglomerate. In order to produce products with uniform and smooth particle size, appropriate fertilizer granulator machine should be selected. Disc granulator and rotary drum granulator can produce moderate size particles and meet the requirements. If there is a higher requirement for the shape of the particles, it can also be combined with the ball shaping machine to polish the particles to ensure that the shape is qualified.

Strengthening the control of screening machine

In order to ensure the consistency of particle size and reduce the caking of powder, it is necessary to screen particles with the rotary drum screener machine. According to the particle size of the product, different screens can be selected, and secondary screening can be selected in the process. Pay attention to the material screening in production, timely clean the screen.

Dryer reduces product water content

NPK compound fertilizer has a high water content, which will lead to salt reaction and cause hardening. The higher the water content, the easier the particles to agglomerate. Therefore, the NPK compound fertilizer production line must use a dryer to reduce the moisture content to the allowable range.

After the particle is dried by the dryer, the temperature is higher and the hygroscopicity effect will appear, so it needs to be cooled. The cooler reduces the material temperature to room temperature, and the product can be saved.

Coating treatment is used in NPK fertilizer production process

Choose the suitable material and use the fertilizer coating machine to coat the particles. At the same time, pay attention to the amount of wrapping agent added. The amount of wrapping agent added is small, the particles are not wrapped completely, the effect is poor; the amount of adding is large, the wrapping oil will infiltrate into the inside of the NPK fertilizer, and the product is easy to cake.

How to maintain the fertilizer granulator machine?

Written by fertilizer production line on December 2nd, 2019.

The organic fertilizer production line is generally divided into two processes of fermentation and granulation. The fertilizer granulator machine plays an important role in the whole organic fertilizer production process. The quality of granulation also affects the quality and shelf life of organic fertilizer granules, thus affecting the selling price.

In the NPK fertilizer production line, the fertilizer granulator machine plays an equally important role, which is very important for the production quality of fertilizer granules. Therefore, we usually need to do maintenance work.

fertilizer granulator machine

The fertilizer granulator machine is divided into a drum granulator, a tooth granulator, a flat die granulator, a disc granulator, etc. Although the working principle is different, the daily maintenance method is basically the same, as the equipment is really damaged, it is needed. Looking for professionals to come to repair, we do the purpose of daily maintenance of organic fertilizer granulator, which is to reduce and avoid equipment damage and affect the economic losses caused by organic fertilizer production operations. So how the organic fertilizer granulator should be maintained in daily use?

Fertilizer granulator machine maintenance method:
1. Keep the work site clean. Every time the organic fertilizer equipment is tested, the granulated leaves and the residual rubber sand inside and outside the granulating pot should be thoroughly removed, and the rubber sand and the fly-filled materials scattered and splashed on the organic fertilizer equipment should be cleaned. Wipe the machine surface exposed to the outside, apply anti-rust paint, and put on the corresponding cover to prevent secondary intrusion of dust.

2. The organic fertilizer equipment has no external oiling holes, and the gears and worm gears are lubricated with special butter for organic fertilizer equipment. The upper gear and the lower gear should be added with three times of butter per season. When refueling, the moving gear box cover and the transmission gear cover can be opened separately. Oil lubrication should always be dripped between the sliding gear box and the sliding surface of the bracket hinge. The worm gear box and bearing are shipped with the transmission butter, but the gearbox machine should be thoroughly cleaned once every one year of use, replacing all protective lubricants.

3. Always pay attention to the operation of the equipment, there should be no serious noise, and there should be no metal friction sound. If abnormality is found, stop using it immediately, check it, and use it after troubleshooting. If there is metal friction, check the gap between the organic fertilizer equipment.

4. Always check the standard gap between the devices.

5. When the equipment is overhauled, the working gap should be re-measured each time and adjusted several times to meet the standard before continuing to use.

6. If the device controller cannot be operated, check the power supply voltage, power socket, connection plug, etc., and check the internal fault of the controller.

How to select fertilizer granulator suitable for compound fertilizer production

Written by fertilizer production line on November 29th, 2019.

Solid compound fertilizer granules are more effective than other fertilizers in use and soil, and are widely welcomed in the market. Fertilizer granulation is a basic treatment method in fertilizer production. Fertilizer granulator machine mixes different fertilizers into granules, which plays an important role in NPK fertilizer production line.

Basic fertilizers such as ammonium bicarbonate, urea, ammonium chloride, ammonium nitrate, ammonium sulfate, ordinary superphosphate, calcium magnesium phosphate, ingot phosphate, heavy superphosphate, potassium chloride, potassium sulfate, phosphate nitrate, dicalcium phosphate, potassium nitrate and so on are proportionally compounded to make the compound fertilizer we need, which is granulated by fertilizer granulator. Granulation is the granulation of fertilizer containing water. In NPK fertilizer production equipment, the commonly used fertilizer granulator machine includes double roller fertilizer granulator, rotary drum granulator and disc fertilizer granulator.

Fertilizer granulator machine granulates by agglomeration

The working principle of drum granulator and disc granulator is similar. When urea, calcium superphosphate, ammonium sulfate, ammonium phosphate, ammonium nitrate, potassium fertilizer and other fertilizers are mixed, they are aggregated into compound fertilizer granules through granulation operation. Rotary drum granulator and disc granulator are suitable for granulation of various ingredients, and the obtained granules are of good quality and high granulation rate of materials.

The main body of the rotary drum granulator is a horizontal drum. The drum is driven by motor, reducer and gear, which is supported by wheel and rollover. The drum granulator has strong production capacity, long material residence time and good granulation effect.

The main body of the disc granulator is a slightly inclined disc, which continuously rolls to complete granulation. In the production of disc fertilizer granulator, the production situation can be seen directly, which is convenient to observe and adjust in time, and the granulation rate of compound fertilizer is high.

Fertilizer granulator machine granulates by extrusion

The double roller fertilizer granulator makes the material into granules by extrusion method. The water content is not higher than 15%, and the materials with good fertilizer effect are mixed after mixing, and the material is strongly extruded by the roller press granulator, so that the molecular force between fertilizers acts and is extruded, and then the sheeted material is crushed into granular compound fertilizer.

How to choose fertilizer manufacturing process plant

Written by fertilizer production line on November 27th, 2019.

Fertilizer promotes the development of ecological agriculture, and the demand is huge. Investment in building fertilizer plants has become a popular project. Some investors want to build small-scale fertilizer manufacturing process to save costs, while some investors in fertilizer plants are going to build large-scale fertilizer plants to save unit production costs.

So what should we pay attention to when purchasing fertilizer manufacturing process plant? Here are some notes.

Determine the type of fertilizer and producton site. Determining whether to produce organic fertilizer or compound fertilizer affects the choice of site. If organic fertilizer is produced, it should not be too far from the farm where raw materials are provided. The type of fertilizer determines whether compound fertilizer equipment or organic fertilizer equipment is needed. Different types of fertilizer equipment also have differences.

Determine the fertilizer granulator machine. Granulation is the key link in fertilizer production and plays an important role in the quality of manufactured fertilizer. Fertilizer granules are cylindrical, spherical and flat spherical in shape. The granules produced by granulators of different shapes are different. The choice of granulator is related to the scale of fertilizer plant construction and local market. Fertilizer factories have different investment scales, different production processes, and different supporting equipment.

If a small fertilizer plant is to be built, it is suggested to configure simple machinery and equipment to reduce investment in equipment. The small fertilizer production line is composed of crusher, mixer, granulator, drum screener and automatic packing machine. If organic fertilizer fermentation is needed, it can be carried out with batten fermentation and windrow turning machine. The advantages are that they are more in line with the principle of aerobic fermentation. It is not easy to form anaerobic fermentation. The fermentation is full and complete, and the fermentation speed is fast. Forklift trucks can also be used instead of turner (the effect is not as good as turner), which can be adopted in terms of saving investment. According to the local environmental protection requirements, choose dust removal settings, where environmental protection requirements are high, choose heavy dust settings to meet the local emission quality standards.

Investment in large and medium-sized fertilizer plants, fertilizer production equipment can choose turning machine, automatic batching system, loader feeding hopper, crusher, mixer, granulator, dryer, hot stove, cooler, feeder, screener, cyclone dust collector, packing machine, etc. Increase mechanical automation, save manpower and cost. Organic fertilizer tank fermentation, can choose simple compost turning machine, double screws compost turning machine (suitable for large yield).

Determine the manufacturer of fertilizer manufacturing process plant. Several fertilizer machine manufacturers were inspected, and the strength, scale and reputation of the manufacturer of fertilizer equipment were fully understood. It is better to inspect the production workshop, finishing workshop and assembly workshop of the enterprise, to know the product quality, processing equipment, production process of the enterprise, and whether the fertilizer equipment produced by the manufacturer is professional. Referring to the customer cases that the manufacturer has completed, on-site test machine, the production site can best show the real operation of the equipment. Looking for fertilizer equipment suppliers with perfect after-sales service, suppliers provide professional technicians to guide customers to install and debug equipment, so that the equipment can operate normally, and provide corresponding training services.

Determine the safety performance of fertilizer manufacturing process plant. Safety is the first, before purchasing, we need to consider whether the production line has safety devices, whether the machine design is reasonable, whether safety factors are taken into account, whether the parts are not welded properly, whether the bolts are tightened, whether there is pollution, and so on. In addition, whether the overall operation of the equipment is smooth and whether the design of the production line is reasonable are also matters needing attention, because it relates to the efficiency and quality of the operation of the equipment. With the permission of the manufacturer, the operator can try to operate it in practice and feel its state conveniently.

How to maintain fertilizer manufacturing equipment

Written by fertilizer production line on November 26th, 2019.

Fertilizer equipment is an important tools for fertilizer manufacturing process. Fertilizers processed by fertilizer equipment have abundant and diverse nutrients, which are rich in materials needed by vegetation and can meet the needs of various nutrients for crop growth. After fertilizer equipment is put into production, attention should also be paid to maintenance and maintenance, not just production. Running the equipment according to usage standard to produce fertilizer, check regularly to ensure normal operation, so that the service life of the equipment is longer. Following are some techniques for maintaining fertilizer equipment.

Bearings in fertilizer production equipment bear all the loads of the machine, so good lubrication has a great relationship with bearing life. The use of bearings affects the service life and operation rate of the machine. Therefore, it is recommended that bearings be inspected once every 7 days and lubricating oil be injected into them regularly.

Check the machine of the whole fertilizer production line regularly, and pay attention to whether the work of each part of the fertilizer granulator machineis normal. The wear level of vulnerable parts should be checked, such as cleaning the chain every 3 days, and replacing the worn parts in time.

If there is a fault in the running of the rotating gear, stop immediately to check and eliminate it.

The chassis of fertilizer production equipment should be placed smoothly to remove dust and other impurities, so as to avoid special circumstances and serious accidents in the production of machinery.

fertilizer manufacturing process

It is suggested that fertilizer factories should do the following for fertilizer manufacturing process:

1) Improve the maintenance system and eliminate hidden dangers. When the fertilizer production line is put into production, it is necessary to formulate rules for the use of various machines and maintenance systems. Operators can operate and maintain according to the regulations, so as to prevent safety accidents and avoid unnecessary failures of machines. For example, when workers clean and maintain the machine, they can find out the problems existing in the machine and check them in time to avoid greater losses.

2) Maintenance of the machine should be carefully and in place. Whether the NPK fertilizer production process can operate efficiently and normally and give full play to its performance is not only related to the quality of the equipment itself, but also to the correct use and proper maintenance of the operators. Maintenance of the machine is troublesome, but if not done, it will affect the production of equipment products, maintenance costs and replacement costs of vulnerable parts will continue to increase.

3) It is necessary to assign responsibility, check and record every day, lubricate and maintain the important parts of the equipment (vulnerable parts, motors, reducers, bearings, etc.) according to the instructions before leaving work every day. If there is any damage, it should be replaced or repaired in time to avoid affecting the normal production the next day.

4) The cause of equipment failure should be analyzed in time and lessons learned. The reason for the failure of fertilizer equipment may be the failure of the machine itself, or the improper operation and maintenance, etc. Once the fertilizer equipment fails, we should analyze the causes of the problems, take measures to learn lessons and prevent similar situations from happening again.

How to Operate Cow Manure Organic Fertilizer Production Equipment

Written by fertilizer production line on November 26th, 2019.

How to deal with cow dung in cattle farm? In the process of cattle breeding, if the cow dung is not handled in time, it will cause air pollution, breed a large number of mosquitoes and flies, pollute the surrounding environment of the farm and cause cattle diseases. Treating cow dung to turn waste into treasure can also bring huge benefits.

Making cow dung into organic manure is one of the main methods to treat cow dung. Dry cow dung contains 10%-20% crude protein, 1%-3% crude fat, 20%-30% nitrogen-free extract and 15%-30% crude fiber, so it has high nutrients. An organic fertilizer production line can efficiently convert cow dung into organic fertilizer.

Organic Fertilizer Production Equipment

Cow Dung Organic Fertilizer Production Equipment and Process Step

1.Fermentation is the first important step

The cow dung produced by a cow in one year requires 4 to 6 cubic meters of space. According to the scale of farming, reasonable construction of cattle dung accumulation fermentation site. Adding 10%-15% straw, rice bran and other supplementary materials to cow dung, and adding appropriate water, the water content of cow dung can be controlled at about 60%, inoculated with starter, and the fermentation time is 15-40 days (depending on the season).

In organic fertilizer fermentation, turning is an important phase. Its purpose is to enable the materials mixed. By the thrown over, it course of the materials make the most contact with the air and get the best fermentation.

Trough Compost Turning Machine, Double Screws Compost Turning Machine (Suitable for large field flip), Windrow Turner (Suitable for strip stacking).

2.Crushing raw material

The fermented materials and other additives are crushed, proportioned and mixed through material grinder and mixer in a certain proportion. The function of this system is to crush, mix and mix compost materials, inorganic fertilizers of nitrogen, phosphorus, potassium and other additives in a certain proportion. Based on years of experience, the following equipment is recommended:

Half-wet Material Crusher

The machine is mainly used to crush materials of biological fermentation organic fertilizer with moisture of 25%~50%. Have good effect on grinding the glass brick, ceramics and broken stone such kinds of hard matter from the city life garbage organic fertilizer.

Horizontal Mixer

Horizontal mixer stir material in batches, material can be mixed completely. High mixing rate, less residual suitable for feed, concentrated feed, premix additives mixing.

3.Pelletizing

New Type Organic Fertilizer Granulator is used to granulate the material. The organic fertilizer granulator is the newest technology products by our years of research experience. It process fertilizer powder into granules, it also can be achieved the better effect of grain making to acid and municipal sludge. We also supply disc fertilizer granulator and flat die pelleting machine for organic fertilizer production.

4.Drying, cooling and screening

After granulating, the fertilizer moisture is a little high. Use organic fertilizer Rotary Dryer, further remove water, to achieve the standard requirements of organic fertilizer moisture content.

Cooling the particulate matter with a Rotary Cooler helps to store the heat particulate matter from the top of the dryer to the counter-flow cooler. Under the action of the cooling fan, the dry air enters from the lower part of the cooler and exchanges sufficiently with the wet and hot particles from the upper tribe and the lower tribe.

There are some differences in particle sizes of the particles exported from the pelletizing and forming system, which requires sieving and grading. Drum Screener Machine has the advantages of low vibration, low noise and convenient screen change. The organic fertilizer manufacturing process is equipped with automatic feed-back system, which screens the unqualified large and small particulate materials, conveys them through belt hoist, re-crushes them and sends them to the granulator to continue granulating, which is helpful to improve the continuous operation ability of the production line.

5.Packing

Packing Machine weighs and packs the particulate matter quantitatively. Automatic quantitative packaging of powder and granules, suitable for flour, starch, feed, food, chemical industry, light industry, building materials industries.

Using cow dung as raw material to produce organic fertilizer has the advantages of low cost, stable quality, fluffy soil, improved land consolidation, improved soil fertility, and great marketing space. As a leading fertilizer equipment manufacturer in China, we have a professional organic fertilizer manufacturing process, which can make cow manure into organic fertilizer with high efficiency and benefit.

Cow manure organic fertilizer production line

Written by fertilizer production line on November 25th, 2019.

The cow manure organic fertilizer production line uses crops such as straw and rice bran as fillers, and then sprinkle the biological strains through the turner. It is turned over once every 1-2 days. It can be completely decomposed in 7-10 days and made into a national standard organic fertilizer.

organic fertilizer production line

The technical route for the production of organic manure from cow dung includes two major steps: raw material aerobic composting process and commercial organic fertilizer fertilizing process.

Among them, the aerobic composting process is used in the fermentation process. Modern aerobic composting is a method in which the manure is used to stabilize and harm the cow dung under aerobic conditions by using aerobic microorganisms, and then converted into high-quality fertilizer. Before the composting, the cow manure raw material is pretreated to meet the fermentation conditions such as water and carbon-nitrogen ratio. In the fermentation process, the compost turning machine is used to turn over and accelerate the fermentation speed. After composting, the cow manure can be fermented and then enter the fattening process. According to the need, it can be further processed into powdery organic fertilizer and granular organic fertilizer products, or mixed with chemical fertilizer to make various organic and inorganic compound fertilizer products to realize commercial production. .

The fertilizer manufacturing process requires a crusher, a mixer, a cooling and drying machine, a fertilizer granulator machine, a sieving machine, a packaging machine, a dust removal system, and the like.
1. The pulverizer comprises a half wet material crusher machine;
2. The mixer has an optional horizontal mixer or a disc mixer or a twin-shaft mixer;
3. The dust removal system consists of a settling chamber and a dust collecting room.
4. The cooling and drying system can be used to dry and cool the fertilizer granules.
5. The fertilizer granulator machine has organic fertilizer granulator, disc granulator, drum granulator, etc;
6. The screening system is mainly completed by the drum screening machine, and the first-stage screening machine and the second-level screening machine can be set to make the yield higher and the particles better;
7. The finished packaging system generally includes an electronic quantitative packaging scale, a silo, an automatic sewing machine, and the like. In this way, the batch-free production of the fully automatic cow manure organic fertilizer production line can be realized.
