The mixing tooth organic fertilizer granulator is currently the most popular product on the market, and it is also a product widely loved by customers. If the organic fertilizer rounder is added, the process has high output, and the processing and granulation can be comparable to disc granulation. The ring die granulator has the highest granulation density, and the granules will not be scattered during the sales and transportation process, but a rounder must be added later to achieve the rounded finished product. From this, it can be seen that the organic fertilizer rounder plays an important role in the improvement of the quality and form of organic fertilizer in the granulation process of the npk fertilizer production line.

The performance characteristics of the organic fertilizer round polishing machine, we can see its own functional characteristics by looking at the name of the organic fertilizer rounder. , and become round particles and balls, no secondary processing and material return are required, which effectively improves the working speed and efficiency of the equipment.

1. Wide application: The round polishing machine itself has been subdivided and classified according to the different output requirements of customers, and the output span is large, which can meet the various needs of different output.

2. Good quality: The organic fertilizer round polishing machine itself has several assembly and coordination, which solves the problems of excessive equipment investment and high cost, and the uniformity of its own product quality also solves the drawbacks caused by different quality standards of finished products.

3. Easy installation: The rounding machine has achieved flexibility in the development of the process, and can realize the simultaneous use of one or several equipment, which can effectively solve the problem of insufficient granulation output, and the installation and maintenance of the equipment are very simple , without too many complicated processes.

The organic fertilizer production line has different equipment configurations according to the different raw materials, and is divided into three configurations: high, medium, and low. The organic fertilizer production line with medium and low configurations is suitable for small and medium-sized fertilizer factories. The sales range of finished organic fertilizers is in nearby areas, and some processes in the organic fertilizer production process need to be completed manually; Large fertilizer factories need to adopt a complete set of advanced production configurations, and the appearance and nutrient content of the finished products can meet market requirements, which has a significant advantage in the promotion of finished organic fertilizers.

The prices of organic fertilizer production lines with different yields also vary, and suitable plans can be made based on the investment budget.

If producing powdered organic fertilizer for processing, only one fermentation equipment, crusher, and screening machine, needs to be invested. The investment is just over 60000 yuan. If producing granular organic fertilizer, it is necessary to add an organic fertilizer granulator, dryer, and a cooling machine is generally not required for an annual production capacity of 10000 tons of organic fertilizer. The investment amount is about 200000 yuan. The construction site can be large or small, and generally requires 3 to 5 acres of land.

Firstly, after sorting and crushing, chicken manure enters the fermentation stage. This stage is very important as organic waste undergoes deep fermentation here, producing beneficial microorganisms and enzymes.

Next, the fermented organic materials will be dried to reduce moisture content and facilitate subsequent processing. Then, after screening and crushing, the powdered organic fertilizer obtained will undergo formula adjustment to meet the needs of different crops.

Finally, organic fertilizers can be packaged in various bags or forms for convenient storage and sales.

In order to smoothly carry out the above process flow, the supporting equipment of organic fertilizer production equipment is also crucial. Common supporting equipment includes waste crushers, fermentation composters, dryers, screening machines, and packaging machines. These devices can effectively improve production efficiency and product quality, while also reducing labor costs and energy consumption. Of course, the equipment models and configurations required by organic fertilizer production enterprises of different scales may also vary, and the selection should be based on specific circumstances.

The npk fertilizer production line mainly includes feeder, disc mixer, chain crusher, drum granulator, drum dryer, drum cooler, drum screener, finished product warehouse, automatic packaging machine, belt conveyor , dust settling chamber, heat exchanger, etc. Commonly used granulation equipment for organic fertilizers are: disc granulator, double roller granulator, drum granulator, wet granulator, counter-roll extrusion granulator, flat die granulator, ring film granulator granulator.

1. The rotary drum granulator raw materials: It can be used for the granulation of livestock and poultry manure, composted manure, green manure, sea manure, cake manure, peat ash, soil and miscellaneous fertilizers, three wastes, and microorganisms.

2. The rotary drum granulator is a process of compound fertilizer granulation, and it can also be used to produce organic fertilizer, but the granulation rate is low.

3. The principle of rotary drum granulator is that the material relies on surface tension, an appropriate amount of liquid phase, the extrusion force generated by rolling between materials, and the material is centered on small particles in the correct direction of movement in the granulator. Large adsorption and small adhesion, bonding into balls. The higher the rolling frequency in a certain period of time, the higher the spheroidization rate, and the more rounded the pellets are after they are formed.

4. The organic fertilizer rotary drum granulator used in small and medium-sized fertilizer plants is a rotating circular simple with a diameter of 1.2-2.4m and a length of 3-6m. Set up a retaining ring at the feed end and the middle part of the simplified, and the tail is light. The middle retaining ring of the organic fertilizer drum granulator divides the simplified into two areas, the front area is the mixing granulation area, and the rear area is the particle polishing area.

Due to the long-term application of chemical fertilizers, the lack of organic fertilizers, and the imbalance of various nutrient ratios, the farmland ecological environment, soil physical and chemical properties and soil microbes are in my country. The bio-organic fertilizer has achieved satisfactory results in the verification of fertilizer efficiency and various crops, and has been recognized by many citizens.

Organic fertilizer granulator equipment double roller granulator uses pressure to agglomerate the solid material, and then squeezes the material through two counter-rotating rollers, which are driven by an eccentric sleeve or a hydraulic system. When extruding solid materials, the air between the powder particles is first removed to rearrange the particles, thereby eliminating the gaps between the materials.

In the npk production line, the extruded organic fertilizer granulator should prevent the granular powder materials from being put into the extrusion granulation equipment, and then the powder materials are compressed by external force. Due to the different modes of external force used, the molecules are reassembled so that the material assumes cylindrical particles. The entire production and extrusion process is mechanized without manual operation. However, agitation granulation primarily uses agitation to form a material into a circle. The bulk product produced by the extruded organic fertilizer granulator has a thickness of 5-20 mm and a surface density of 1.5-3 times that of the feed. The chunks are then sliced, crushed and sieved to obtain the desired granular product.

The double-roll extrusion granulator adopts the non-drying and normal temperature process, and the particle strength is high. In the npk fertilizer production line, the increase in the accumulation proportion is more obvious than other granulation methods, the reliability of electric power small operation, the three kinds of wastes are not discharged, and the operation is stable , easy maintenance, reasonable process layout, advanced technology and low production cost. The twin-roll extrusion granulator realizes the green reuse of resources and has huge market potential.

The granulation process of an annual production line of 20000 tons of chicken manure organic fertilizer:

The granular organic fertilizer production line with an annual output of 20000 tons of chicken manure includes a stacker – vertical crusher – drum screening machine (optional here) – batching machine and horizontal mixer (optional equipment) – disc granulator – dryer and cooling machine – drum screening machine – round throwing machine (optional) – coating machine (optional) – single bucket packaging machine.

With an annual output of 20000 tons and a large scale, it is possible to consider using a granular fertilizer production line. The granular fertilizer production line includes two important processes, fermentation and granulation.

Fermentation process for the production of chicken manure organic fertilizer:

Mix chicken manure, straw, mushroom residue, and other materials together, add fermentation agents, and under the action of the fermentation agents, the material pile will generally heat up in about 2 days. At this time, flipping equipment can be used to flip the pile to increase the oxygen content and moisture content of the material pile. If local environmental protection is strict, horizontal fermentation tanks can be used for fermentation. The fermentation process in horizontal fermentation tanks is fully sealed and contains deodorization devices, which will not cause environmental pollution.

Granulation process of chicken manure organic fertilizer production line:

After sufficient fermentation and maturation, the material enters the granulation process. The finer the material, the better the shape of the produced particles. Therefore, it is necessary to first use a vertical crusher for crushing, and then use a drum screening machine to screen. Materials with unqualified dimensions enter the crushing process again, and qualified materials enter the organic fertilizer granulator. An annual output of 20000 tons of granular fertilizer. It is recommended to use disc granulators, toothed granulators, etc. for circular particles, and flat mold granulators and roller extrusion granulators are recommended for cylindrical particles. After the granulation is completed, the screening machine is used again for screening. Unqualified particle materials enter the crushing granulation process again, and qualified particles enter the packaging machine.

The production process of fermentation and granulation is relatively simple, but equipment selection is important. Stable performance and well-designed equipment can not only avoid production accidents, but also improve the quality of organic fertilizers.

The npk manufacturing process mainly includes feeder, double roller granulator, dryer, cooler, drum screening machine, finished product warehouse, automatic packaging machine, etc. It is necessary to master the functions of the equipment, be familiar with the non-organic fertilizer equipment, maintenance essentials, Operation methods of consumption capacity and scope of application, familiar with the functions of all controllers and alarm devices of organic fertilizer processing equipment. At the same time, we must pay attention to the safety accidents that may occur when the equipment is continuously operated under high pressure and low temperature. Various problems that may occur in organic fertilizer processing equipment. When there is organic fertilizer equipment production, we must pay attention to safety. We can only work better when we have security. At the same time, pay attention to the daily maintenance of the equipment.

1. Keep the machine clean. After use, the stains and debris outside the organic fertilizer granulator should be removed, coated with black oil, waste oil, etc, and covered with a protective cover.

2. Deal with corroded and damaged parts in time. When the equipment is not working, the corroded or damaged parts in the equipment should be removed, especially the motor, reducer, conveyor belt, transmission chain, etc.

3. Pay attention to the operation of the organic fertilizer equipment. Once serious abnormal noise is found, the npk fertilizer production line inspection should be stopped immediately and used after troubleshooting.

4. For outdoor organic fertilizer equipment, the deformed part should be leveled or erected to remove the factors causing deformation.

5. When the organic fertilizer equipment is overhauled, the working gap should be re-measured each time and adjusted several times. It can only be used if the standard is met.

6. Do a good job of thermal insulation. The drive part of the fertilizer equipment may start slowly or fail to start due to freezing. Therefore, insulation measures can be taken. At the same time, antifreeze is also used for raw materials commonly used in the operation of organic fertilizer equipment.

The investment cost of organic fertilizer plant mainly includes land rent, plant construction, organic fertilizer production equipment, cost of raw materials and auxiliary materials, labor cost, electricity fee, etc. Organic fertilizer production equipment: a set of npk production line: fermentation turning and throwing equipment, feeding hopper, crushing equipment, granulator, screening equipment, cooling dryer, belt conveyor, packaging equipment, etc.), granular production line, 250,000; The larger the annual production capacity, the higher the price. 

Organic fertilizer granulator is one of the core equipment of organic fertilizer equipment, which directly affects the roundness, uniformity, fertilizer and water retention performance of organic fertilizer particles. Different types of granulators should use different types of granulators to directly affect the output, quality, appearance, price of the product. In the npk manufacturing process, what type of granulator is needed for the production of granular organic fertilizers. Learn about the double-roll granulator and the drum granulator today.

Double roller press granulator

The double roller granulator belongs to dry granulation, no drying process is required, and the granulation density is high, the fertilizer effect is good, and the organic matter content is full. Save the cost of buying dryer and cooler, no need to burn coal in the later stage, which saves a lot of money. The size of the extrusion force can be adjusted by hydraulic pressure, and the operation is flexible. It is suitable for various industries such as fertilizer, medicine, chemical industry, and feed. The design is reasonable, and it can be used together with the corresponding equipment to meet the continuous production of the production line.

Rotary drum granulator

The rotary drum granulator is a process of compound fertilizer granulation. It can also be used to produce organic fertilizer. It has high work efficiency and is lined with rubber engineering plastic material. The granulation rate is high, there is a small amount of returned material, the particle size of the returned material is small, and it can be re-granulated again, saving costs, and heating the material by steam to increase the temperature of the material, so that the moisture of the material is low after the material is formed into a ball, and the drying efficiency is improved.

There are many types of organic fertilizer crushers, including vertical crushers, chain crushers, semi wet material crushers, urea crushers, straw crushers, new straw crushers, etc. The selection of a suitable pig manure organic fertilizer crusher mainly depends on several aspects such as production scale, material requirements, and operational requirements. Now let me give you a detailed introduction.

Firstly, according to the scale of production, pig manure organic fertilizer crushers can be mainly divided into three types: small, medium, and large. The small pig manure organic fertilizer crusher is suitable for small family farms or individual operators, with a general processing capacity of 1-2 tons/hour; The medium-sized pig manure organic fertilizer crusher is suitable for medium-sized factories or farms, with a processing capacity of 2-5 tons/hour; Large scale pig manure organic fertilizer crusher is suitable for large factories or farms, with a processing capacity of over 5 tons/hour.

Secondly, according to material requirements, the pig manure organic fertilizer crusher can be divided into two types: stainless steel and carbon steel. The stainless steel pig manure organic fertilizer crusher has corrosion resistance and is suitable for processing pig manure containing more acidic and alkaline components, while the carbon steel pig manure organic fertilizer crusher is more wear-resistant and suitable for processing pig manure with strong viscosity.

Finally, according to operational requirements, the pig manure organic fertilizer crusher can be divided into two types: manual and automatic. The manual pig manure organic fertilizer crusher requires manual operation and is suitable for places with simple operation and sufficient human resources; The automatic pig manure organic fertilizer crusher has automatic control function, suitable for situations with high work intensity and complex operation.

In summary, selecting the right pig manure organic fertilizer crusher requires comprehensive consideration of production scale, material requirements, and operational requirements.

The principle of rotary drum granulator is that the material relies on the surface tension, the right amount of liquid phase, the extrusion force generated by the rolling between the materials, and the material takes small particles as the core in the correct direction of movement in the granulator, and sucks big during the rolling. Small attached, glued into a ball. The higher the rolling frequency in a certain period of time, the higher the spheroidization rate, and the more rounded the pellets are after they are formed.

1. In the npk production line, we have encountered two situations due to the different friction between the material and the wall of the granulator. The inner surface of the granulator has a large surface finish, which reduces the friction between the material and the cylinder wall, and weakens the upward movement of the material. If the material does not roll, particles cannot be produced. In response to this situation, we can solve it by adjusting the speed of the granulator and installing a small copy board inside.

2. The material in the rotary drum granulator is seriously sticking to the wall, and the friction between the material in the granulator and the cylinder wall is enhanced, and the material in the granulator is lifted too high, causing the material to be thrown down from the top, so that the formed particles are not round. And too many large particles, we think there are two reasons for this situation: on the one hand, it is caused by too many viscous materials. The inside of the machine is not smooth, which is solved by changing the internal material and increasing the smoothness of the granulator.

The double roller press granulator is the key equipment for compound fertilizer granulation. It has advanced technology, reasonable design, compact structure, low energy consumption, and is matched with corresponding equipment to form a small production line, which can form a certain continuous production and mechanized production. , No drying, room temperature production, capacity, product quality meet the technical requirements of compound fertilizer, it is the latest product of energy saving and consumption reduction of npk production line of high, medium and low concentration special compound fertilizer and compound fertilizer industry.

The double roller granulator has the characteristics of low energy consumption, high energy saving, low investment, simple operation, and pollution-free equipment emissions. The distance between the pressure rollers should not be too small or too large, and should be adjusted within the specified range. Secondly, the pressure cover on the bearing seat side should be avoided to be too loose or too tight, which will cause the shaft rollers to shift.

1. Uniform feeding: Since the surface of the biological fertilizer granulator is friction material and direct force, in the npk manufacturing process, when the roller surface is worn, the friction and back pressure of the material cannot be ignored. This force requires higher quality roll skins, lower mass wear rates, and lower mass wear rates. If the feeding is not uniform, the center of the parallel bar axis of the biofertilizer granulator is parallel to the surface of the roller sheet, the feeding at one end and the feeding at the other end will cause uneven force at both ends of the roller, thereby increasing the friction between the roller and the material , resulting in roller wear.

2. Material pH: Since the roller cover of the biological fertilizer granulator is made of stainless steel, it has a strong response to the pH of the material. Due to the lack of moisture and alkalinity of the material, it will cause acid and alkali corrosion on the surface of the roll and damage the roll. If the operating procedure does not work, the gap between the rollers will not be properly adjusted and contain impurities such as iron and sulfur. The color phase can seriously damage the roll surface.
