Model Selection of Organic Fertilizer Granulator

Written by fertilizer production line on December 29th, 2022.

The difference in the selection of organic fertilizer granulator models lies in the selection of appropriate granulation methods according to the use requirements of materials. This is just a big general term. There are subdivisions and branches under it. It is mainly divided into dry method and wet method:

Dry process mainly refers to products with relatively low water content. Generally, water content below 10% is a zero limit. (There are also few materials that can reach 16%, for example, some materials only carry crystal water.) Most of the particles produced by dry granulation are irregular particles (for example, ordinary granular potassium fertilizer) or the more common shape is similar to small gravel. With the current industrial upgrading and increasingly strict environmental protection requirements in China, many chemicals and building materials need granulation.

The main index of wet granulation is the material with a water content of more than 20%. There are various equipment and methods for wet granulation. For example, disc granulation, drum granulation and spiral granulation have been carried forward many years ago, and have been greatly improved by increasing the use environment and processing requirements of different materials. For example, the particle size of relatively popular organic fertilizers over the years ranges from 1mm to 6mm. These methods were adopted.

Compared with wet granulation, dry granulation in organic fertilizer granulator consumes less energy, is more environmentally friendly, does not require drying, does not add water and binder, and does not change the properties of materials; Compared with wet granulation, these are also several advantages of dry granulation. It is more suitable for industrial production.

In another case, some materials require relatively small particle sizes. Products between dozens of meshes and 100 meshes can also be reduced by airflow, spray and rapid drying.

Equipment and technology of packaging machine in npk fertilizer production line

Written by fertilizer production line on December 29th, 2022.

Automatic packaging machine is an indispensable production equipment of NPK production line, which improves the efficiency of the whole production process.

Innovation is an important part of the development of automatic fertilizer packaging machine. Although there are many kinds of automatic fertilizer packaging machines, most of them are semi-automatic operation. They only carry out targeted bagging and sewing. The packaging method is relatively single and lack of innovative elements. If we don’t pay attention to the renewal of packaging machine technology, the enterprise will be eliminated in the saturated automatic packaging machine market in the future.

Fertilizer automatic packing machine

Automation and intelligence of mechanical equipment is always the direction of its development. Only by constantly innovating and adapting to the needs of the market, can the packaging industry walk out of a new production road. In addition, the technological innovation and upgrading of fertilizer packaging machinery will become a powerful boost to the development of enterprises, and the fertilizer automatic packaging machine, which starts to develop in the direction of diversification, will change the traditional production mode and will develop rapidly. In the fertilizer production industry, the granules produced by the organic fertilizer granulator machine are quantitatively packed in the flow industry.

Through the continuous use of high technology, the position of the automatic packaging machine in the market is becoming more and more stable, and at the same time, its development is opened. Continuously through the improvement of technology, it not only guarantees the efficiency and quality of product packaging production, but also makes it easier to expand into new markets. , To open a new field of development for it. At present, it has been imitated by many companies, but it is still unable to surpass in terms of corporate image and after-sales service, forming a situation where the packaging machine market is uneven and mixed.

We also need to know that the success of the automatic quantitative packaging machine comes from the perfect application of science and technology, and the automatic packaging machine is fully used in the fertilizer production line. In order to maintain its market position, manufacturers of automatic fertilizer packaging machines must carry out the application of science and technology to the end and continuously improve the independent innovation capabilities of core technical personnel.

The reason of raw material precipitation during npk fertilizer granulation

Written by fertilizer production line on December 22nd, 2022.

When some compound fertilizer equipment production lines are processed by rotary drum granulator, they can dissolve the fertilizer into a certain proportion, but if the energy exceeds a certain amount, it will produce salt analysis and precipitate another substance.

Amino acids and zinc sulfate dissolve well in water, but when they are together, Zinc Sulfate Precipitates amino acids. The pH value of solution, part of the supply, metal salt dissolved in acid will produce precipitation and dissolve in alkaline medium, while some substances such as humic acid will form precipitation and dissolve in acid solution. Amino acids and humic acids can be analyzed by salt analysis, zinc, copper, iron, manganese and salt analysis. Therefore, it is more important to choose suitable raw materials for fertilizer production.

Fertilizer granulator granulation should consider whether the substances are compatible. Some substances cannot be mixed in the precipitation reaction, and precipitation occurs when they are mixed into water, such as zinc, copper, iron and manganese plasma. In the case of phosphate, borax will precipitate, the precipitate is insoluble in water, and the phosphate precipitates molybdate ammonia water, and these commodities cannot be produced at the same time. They not only produce precipitation, but also lose their fertilizer efficiency.

Raw materials are insoluble in water, so the proportion of fertilizer is blindly increased. At room temperature, the solubility of borax and boric acid in water is 30 kg / T, and most of them will precipitate. If several kinds of fertilizers are soluble in water, there is also a great demand. For example, zinc sulfate is soluble in water, potassium sulfate is soluble in water, and two kinds of raw materials are soluble in water, which can produce potassium sulfate crystals.

How to improve the granulation rate of drum granulator in organic fertilizer production line?

Written by fertilizer production line on December 19th, 2022.

Producing the organic fertilizer granulator using the fertilizer granulator machine.Different type and model of organic fertilizer granulator machine can be used to produce the organic fertilizer granulator.How to improve the granulation rate of the rotary drum granulator?
In the fertilizer manufacturing process,the new type organic fertilizer drum granulator is a common granulator,which mainly uses high-temperature steam to make raw materials humidified to the granulation state.After the granulation of Huaqiang new type type organic fertilizer drum granulator,the particl temperature is very high.In the next drying process of organic fertilizer particles,the heat energy consumption of drying is saved,which is not efficient and engery-saving,and the granulation rate is up to more than 90%.
In order to improve the granulation rate of the new type organic fertilizer drum granulator in organic fertilizer production line,in addition to selecting a high-quality product,the granulation rate and output of the granulator can also be improve the granulation rate of new organic fertilizer drum granulator:
First,the time and frequency of material rolling in the new type of organic fertilizer drum granulator is the primary factory to determine the pelletilizing rate and particle roundness.The principle of rotating drum granulation is that the material depends on the surface tension,the appropriate liquid phase,the extrusion pressure generated by roller press which the roller press granulator machine is also to be designed and used in npk fertilizer manufacturing process in most of time,and correct movement direction of the material in the granulator is centered on small particles,which absorb and adhere to the ball in the rolling process.The higher the rolling frequency in a certain period of time,the higher the pelletilization rate is,and the rounder the particles will be after forming.In the process of production,we have encountered two situations due to the different friction between the material and the barrel wall of the granulator.
1.The internal surface finish of te granulator is large,which reduces the friction between the material and the cylinder wall,and weakens the upward movement force of the material.If the material does not roll,it will not produce particles.In view of this situation,we can solve it by adjusting the rotating speed of the new type of organic fertilizer drum granulator and installing a small-scale plate inside.
2.The material in the organic fertilizer drum granulator sticks to the walll seriously,the friction between the material in the granulator and the cylinder wall is enhanced,and the material in the granulator is lifted too high,which causes the material to be thrown down from the top,until the particles formed are not round and too many large particles.We think there are two reasons for this situation:on the one hand,there are too many stickly materials ,which we adopt.On other hand,the inside of the granulator is not smooth,which can be solved by changing the inside material and increasing the inside finish of the granulator.
fertilizer equipment
The design of npk fertilizer production line by rotating drum granulation is that there is a steam pipe embeded in the feed bed,and a spray is arranged above the feed bed.Under the condition of stable production supply,the saturated steam provides part of water while providing heat,which increase the moisture content of the material.Through the use of steam,the temperature and viscosity of the material are increased,so that the moisture content of the mateiral can be reduced in the process of balling,thus reducing the drying load, and the liquid phase distribution of adding steam can be more uniform than adding water. Only when the liquid phase of the material is insufficient and the material is unstable, can the water be added as a supplementary means. In the process of production, we have encountered that because of the unreasonable installation of the steam nozzle and the uneven distribution of the liquid phase of the materials, the places where there are many liquid phases of the materials are stuck into a big ball, and the places where the liquid phase is insufficient, the materials are difficult to form a ball, which affects the formation of the particles. In view of this situation, we can increase the steam nozzle to improve the steam receiving area of materials.
In conclusion,in order to improve the granulation rate of the new type organic fertilizer drum granulator,it is necessary to stickly control the water content,carry out the water ratio according to the provisions of the fertilizer equipment manufacturer,and pay attention to the methods in the production process at ordinary times,so as to improve the granulation rate and output of the new type organic fertilizer drum granulator.

Mixing equipment in NPK fertilizer production process

Written by fertilizer production line on December 19th, 2022.

In NPK production line, blender will be used to mix materials. Here is a brief introduction of screw blender.

Structure of screw mixer

Screw mixer is composed of motor, reducer, bracket, screw, shell and other parts. The shell has a feed port, a discharge port and a body seat. There are two types of reducer: cycloid pin gear and worm gear. The screw stirring bar is designed with double cantilever, unequal length, unequal screw distance and different speed. Different from the rotary drum granulator pelleting. This machine is mainly used for bulk blending fertilizer.

The mixer is designed to rotate asynchronously. The screw rotates around its center line and revolves around the conical center line, so that the materials can be fully mixed. Due to the introduction of advanced technology design and manufacture, so that the mixed materials will not be crushed and crushed, no column angle, deposition and other phenomena. The material size is 20~200 mesh, and the mixing time is 5~8min. The discharge port device is equipped with a manual or electric mechanism. The shell and the parts in contact with the material are suitable to be made of stainless steel. This equipment can also be equipped with a water spray mechanism according to the requirements of the production process.

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 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.

Production process of potassium chloride by disc granulator machine

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

In the production of potassium chloride granular fertilizer, fertilizer granulator can be used to granulate powder. The particles produced by disc granulator are spherical and have good strength, which can be widely used in agricultural production.

Disc Pan Granulator

In the granulation process of disc pan granulator, it is necessary to add a binder to make the granules shape. Binder can be compounded by common inorganic minerals in a certain proportion. Binder has synergistic effect when potassium chloride is pelleted. The effect of pelletizing rate and particle strength is good when the binder is used for pelletizing. Potassium chloride was granulated by disc pan granulator machine, and the granules were spherical.

NPK Fertilizer Production Line

NPK fertilizer production line deals with potassium chloride fertilizer. First, all raw materials are mixed by the batching system, and the material is crushed by chain mill to the appropriate size. The disc granulator makes the powder into granules. After drying and cooling, the granules of potassium chloride are coated with protective film by the fertilizer coating machine to complete the granular processing of potassium chloride.

Disc Granulator NPK Fertilizer Production Line

When applying potassium chloride, attention should be paid to the appropriate period of potassium application. Generally, the application period of potassium fertilizer should be early or not late, and should be used as base fertilizer and early recovery period. When the application amount of potassium fertilizer is less, it can be used as base fertilizer once, and when the application amount of potassium fertilizer is more or the soil texture is lighter, the application effect is better divided into base fertilizer and topdressing fertilizer. Soil nutrients and fertilization status should also be taken into account in determining the suitable application period of potassium fertilizer. In severe potassium deficiency soils, all potassium fertilizers should be used as base fertilizers in medium soil potassium supply, and suitable organic fertilizers should be applied as base fertilizers, combined with topdressing.

Note the method of application of potassium chloride. The concentrated application of potassium fertilizer is beneficial to improve its utilization rate and obtain better results. However, it is not advisable to have direct contact with seeds or seedlings. For general crops, a combination of soil fertilization and foliar fertilization can be used.

Economic Benefit of Producing Slow-acting NPK Complex Fertilizer

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

Because of the low utilization rate of chemical fertilizer, people try to make a slow-release and high-utilization fertilizer to meet the demand of nitrogen in different growth stages of crops, reduce the loss of nitrogen leaching and volatilization, reduce the fixation of phosphorus and potassium fertilizers in the soil, so that the fertilizer can supply nutrients according to the requirement of crop fertilizer. The available CaO, MgO, SiO 2 and various trace elements in fertilizers are also good soil amendments. The coated NPK fertilizer manufacturing process can produce suitable fertilizer products.

Slow release coated fertilizer manufacturing process

NPK Fertilizer Production Process

According to the sustainable development of agriculture and the demand of improving fertilizer utilization rate, Zhengzhou Tianci Fertilizer Machine Manufacturer has developed a slow-acting, high-utility coated complex fertilizer manufacturing process. The fertilizer manufacturing process is based on the instant granular fertilizer as the core, one or more slow-release plant nutrients as the coating, inorganic acid complex, slow solvent and other binders to wrap water-soluble fertilizer, forming a complex fertilizer with both quick-acting and slow-acting components. We provide fertilizer manufacturing process including fertilizer granulator machine, pulverizer, rotary dryers, coolers, drum screening machines, coating machines, packing machines and other equipment. The whole set of fertilizer production equipment can complete the processing and coating of the particles of the complex fertilizer, so that the fertilizer has high utilization rate in the soil.

Benefits of NPK Fertilizer Production Process

In the process of fertilizer production, the structure and composition of cladding layer can be adjusted to control the release rate of nutrients so as to reduce leaching loss and improve the utilization rate of fertilizers. This fertilizer product not only has the characteristics of slowly releasing nutrients, but also can meet the needs of nutrients for the whole growth period of crops and the ratio of nutrient utilization rate by one basal application. Conventional quick-acting fertilizer increased by 10-30 percentage points, the utilization rate of nitrogen fertilizer could reach 50%-70%, and the amount of fertilizer used could be reduced by 10%-40%. Due to the remarkable economic and social benefits of slow-acting and high-utilization wrapped complex fertilizer, and in line with the direction of fertilizer development, it is worth vigorously promoting.
