Double Roller Granulator Installation

1. Installation:

After arriving at the plant, the drum extrusion organic fertilizer granulator will be installed with granulator as the main machine. According to the number of units and the organic fertilizer manufacturing process flow chart, the elevation and horizontal position are found. There are corner holes in the frame, which can be installed on the concrete (the solid vibration is not large, and a very solid concrete foundation is not required).

2. Debugging:

Our double roller granulator has been debugged before delivery, but it still needs to be adjusted after trial.

(1) Adjust the press roll clearance

In the production process, it is sometimes necessary to increase data output or data biting angle. In this case, the distance between the two compression shafts can be increased and the clearance between the drive shaft roller and the drive shaft can be increased.

The steps are as follows: stop the roller granulator, remove the frame above the two bearing blocks, adjust the adjusting plate between the two bearing blocks to the required thickness, prevent the roller collision between the two rollers, and maintain a minimum clearance of 0.3-1 mm.

(2) Ball and socket alignment adjustment

The ball and socket are formed by pits on the surface of the main roller, so there are problems of axial alignment and circumferential alignment.

Axial alignment has been adjusted during installation. Generally speaking, the possibility of adjustment is very small. When adjustment is required, tighten or loosen the seal rings on both sides of the passive bearing housing to push the displacement of the eccentric sleeve corresponding to the roller of the drive shaft.

Go our web for the manin structure of the extrusion granulator.

Align the circumference. The steps of circumferential alignment are as follows: loosen the 6 connecting bolts of the drive gear and the adjusting sleeve, so that the adjusting sleeve and the driving gear are slightly separated. Since a spherical and socket adjustment is considered in the design and two adjusting bolts are provided, the deviation can be adjusted no matter the deviation is too large. As the ball sleeve of the double roller granulator is too small, the paperboard is placed between the two rollers during the adjustment process. After scrolling, you can see whether the adjustment has achieved the goal. After alignment, tighten the 8 connecting bolts.

We provide NPK fertilizer granulator equipment, users can get professional engineer's guidance after purchasing the equipment, we provide help in installation.

Machines for Fertilizer Production

Organic fertilizer contains a variety of trace elements, including all the nutrients needed for plant life. In organic fertilizer, we can find all these nutrients, and their nutrition combination is very reasonable. But we can't find them in all the fertilizers. Therefore, organic fertilizer is an indispensable part of agricultural production, organic fertilizer manufacturing machine is very important.

Demand of organic fertilizer for agricultural production

Organic fertilizer is the only material basis to maintain soil fertility and soil health, while chemical fertilizer is far behind. Chemical fertilizer is regarded as opium by ecological farmers. With the increase of chemical fertilizer application, the quality and yield of crops decreased. Organic fertilizer has become the only soil conditioner to solve the problems of nutrient imbalance, soil hardening and microbial damage caused by excessive use of chemical fertilizer.

NPK Granulation Tech

Granulation technology of NPK fertilizer production line with rotary drum granulator

Rotary drum granulator is the main granulating equipment of NPK fertilizer production line. It uses powder composition and agglomeration granulation method to make NPK compound fertilizer molding. The drum granulator developed by our factory adopts a new generation granulation technology, which improves the formation rate of compound fertilizer granules and the qualified rate of primary granulation.


NPK Fertilizer Granulation Plant

Rotary drum granulator

The rotary drum granulator can make NPK compound fertilizer into granules, which is easy to store and release, thus greatly prolonging the fertilizer utilization rate of organic fertilizer. The drum granulator is suitable for cold and hot granulation. It uses aggregate wet granulation, and adds a certain amount of water or steam to the cylinder, so that the extrusion force between the material particles can be condensed into a ball.

Granulation technology of NPK fertilizer production line

In order to improve the granulation performance of rotary drum granulator, we improved the drying process of NPK fertilizer production line after granulation. It can shorten the drying time of fertilizer production, minimize the damage of compound fertilizer particles in the drying process, and increase the numNPK Granulation Tech

For NPK fertilizer granulation, the quality of granulation particle size depends on the proportion and feedback granularity to a certain extent. Compound granulation usually needs batch quality, and the quality of returned materials is the key to control the production of rotary drum granulator. On the basis of ensuring nutrients, the quality of returned materials mainly depends on the size and distribution of returned materials. In order to ensure the quality of returned materials, we set up chain crusher in NPK fertilizer production line.

The chain crusher will re crush the unqualified returned materials, and the crushed powder can meet the granulation requirements of the rotary drum granulator.

Pan Granulation sludge

Steps of sludge biological fertilizer production process

1. The treated sludge (domestic sludge, industrial sludge, etc.), proper amount of qualified raw materials such as nitrogen, phosphorus, potassium, filler, etc. are sent to the raw material mixer in proportion to mix evenly.

2. Transfer to the disc feeder and add the evenly mixed material to the rotating disc of the pan fertilizer granulator through the continuous rotation of the disc. Go here for more details in auxiliary machine: 

3. The treated microbial strains are sprinkled on the disc material through the liquid component distributor of the pan fertilizer granulator, so that each particle is coated with microbial strains from the inside to the outside. The rotating disk and its edge have friction and centrifugal effect on the material, and the powder gradually gathers into the sphere. Due to the difference of particle mass, the gravity and centrifugation are different. When gravity and centrifugation increase enough to overcome friction between particles, they are thrown out of the disk, and smaller particles remain in the circle. Fine powder continues to accumulate in the dish.

4. The fertilizer is transported to the biological fertilizer dryer, and the initial drying of the fertilizer is completed by using the large airflow generated by the fan and the low-temperature hot air. Due to the species, the drying temperature is strictly controlled, and the drying temperature is lower than the survival temperature of the species.

5. Transport to the thermal screening separation particles and return the fine particles directly to the disc feeder as the core continues to participate in adhesion of the particles to the ball.

6. Transfer to the secondary biological fertilizer dryer to make full use of the high air volume and micro heat to dry bacterial fertilizer.

7. Transfer organic fertilizer cooler to cooling fertilizer by natural or forced cold air.

8. Transfer to finished product screening machine. The large particles are crushed by the crusher and returned to the disc homogenizer to continue to participate in the ball.

9. A small amount of microorganisms and bacteria are lost on the surface of the particles passing through the dryer, and the microbial species on the surface of the particles are supplemented by the coating machine. 




10. Transfer to automatic packing scale for weighing, packaging and storage.

11. The drying, cooling and workshop dust are treated by cyclone dust collector, dust removal room and wet washing to meet the standard and empty.

Bio Fertilizer Making Tech

There are many kinds of organic fertilizer, among which bio organic fertilizer is the leader. Biological fertilizer is a kind of fertilizer with the function of microbial fertilizer and organic fertilizer. It is composed of specific functional microorganisms and organic materials. It is mainly used for automatic plant residues (such as animal manure, crop straw, etc.), which are treated by harmless treatment and decomposition of organic materials. It is different from organic fertilizer produced only by natural fermentation (decomposition).

Bio Fertilizer Production


Biological organic fertilizer products not only contain high organic matter, but also contain microorganisms with specific functions, which are the basic characteristics of organic fertilizer products. In addition, the microorganisms in soil have certain fertilizer functions, such as improving soil fertility, producing and assisting crops to absorb nutrients, activating insoluble compounds in soil to absorb and utilize crops, or producing various active substances and disease resistant substances, so as to stimulate and regulate the growth of crops. It can reduce or reduce the occurrence of crop diseases and insect pests and improve the quality of agricultural products.

Production technology of biological fertilizer

Compared with common organic fertilizer, biological fertilizer production technology content is higher. In order to realize directional decomposition and deodorization, biological agents should be added in the decomposition process of organic materials. In addition, microorganisms with specific functions should be added to the product to improve the effect of the product.

In the production process, there are also differences between biological fertilizer and ordinary organic fertilizer. In chemical fertilizer production equipment, biological fertilizer production equipment is the same as ordinary organic fertilizer production equipment, including fertilizer granulator, mixer, crusher, drum plate machine and other equipment. The difference between the two is how to protect the functional bacteria in the production process and improve the survival rate of the strains, so as to maximize the fertilizer efficiency.

Extrusion VS Rotary Granulation

In the process of chemical fertilizer manufacturing, various powders, small pieces, aqueous solutions or melted raw materials are made into particles with necessary appearance and compressive strength. According to the chemical properties of raw materials, efforts should be made to reduce dust pollution, improve performance and improve production and processing effect.



According to the fertilizer manufacturing process in granulation, according to the different aggregation methods of the initial ultrafine particles, the processing technology of the granulator can be divided into extrusion granulation, rolling granulation, spray granulation, hot melt making and fluidized granulation. Pressure granulation and rolling granulation are two common methods of fertilizer production. What is the difference between the two fertilizer production methods?

The pressure granulation method limits the powder form in the closed internal space, releases the external force, and improves the compactness of the material. Pressure granulation can be divided into two types, one is compression molding granulation, in which raw materials are placed in a closed mold cavity and extruded into a cylindrical belt according to repeated movement. The other is double roller granulation, which is commonly used in double roller granulator. In the process of sand pressing, raw materials are crushed, granulated and screened. With the popularization of rollers, materials are formed.

Double roll extruder granulator

Rolling granulation is to infiltrate the binder into the fine powder on the solid disk to produce micronuclei. The rearranged particles are rolled many times and then become spherical particles of a given size. The equipment of roller granulator usually includes disc type fertilizer granulator and rotary drum granulator.

Granulator is an important part of fertilizer processing technology. In order to save costs, some enterprises usually only choose the appropriate granulation equipment for production. Therefore, granulator is not only used in industrial field, but also used in chemical industry and agriculture. According to the market application, granulators include fertilizer granulator, sawdust granulator, plastic granulator, pulverized coal granulator, etc. Understanding the different granulation methods in fertilizer production is helpful to purchase appropriate granulation equipment.
