NPK Fertilizer Granulation and Coating Process

In the NPK fertilizer manufacturing process, the coating process is added to make a slow-release fertilizer. Slow-release fertilizer is also known as controlled-release fertilizer.

The rate of release of nutrients in fertilizers can be controlled to a certain extent for continuous absorption and utilization by crops. After fertilization, the loss of fertilizer nutrients, especially nitrogen, can be reduced in the soil.

It can reduce the frequency of fertilization, saving labor and costs. In order to increase crop yields and incomes, the application of slow-release fertilizers can improve the resistance of crops to disease lodging.

In the production process of nitrogen, phosphorus and potassium fertilizer, the amount of coating agent is controlled according to the length of particle storage time. So what are the precautions for nitrogen, phosphorus and potassium fertilizer granulation coating?

Fertilizer granule coating machine is composed of spiral conveyor, stirring tank, oil pump, main machine, etc., which can effectively prevent organic fertilizer and compound fertilizer from agglomeration, and is an effective coating fertilizer production equipment.

Precautions for fertilization and coating operations

1. When the coating machine is running, please do not remove the protective device.
2. When the coating machine is running, it is forbidden to drill holes under the fuselage.
3. It is forbidden to carry out internal inspection and repair when the coater is running.

4. Do not touch the motor and wires without insulating gloves.
5. When inspecting the furnace and coating machine, it is forbidden to use mobile lights with a voltage higher than 12V.

6. If there is no perfect grounding wire, it is forbidden to start the coating machine. If there is current on the device, stop the machine immediately until the ground wire is repaired.

Top Chosen Granulation Technology in NPK Manufacturing

The compound fertilizer extrusion granulator adopts spiral, two-way rolling, two-way die and double roll granulation, but it is essentially different from other granulation equipment. The granulator enables organic materials to be continuous, high-speed and dense in the granulation area.

Rolling and shearing promote the physical granulation pressure between powder and granular materials to increase significantly.
With this method, the granulation effect is 2-3 times higher than that of conventional extrusion granulator, and the power consumption is reduced by more than 60%.

Double Roller Powder Granulator

Characteristics of NPK compound fertilizer extrusion granulation equipment:

The frequency conversion PID operation feed automatic control system of the double roll granulator ensures that the granulation system produces high power and stability.

It can be widely used in sugar factory sludge filter, alcohol, starch, animal husbandry and other enterprises, and organic waste produces organic fertilizer, biological fertilizer, organic-inorganic compound fertilizer and other commercial granulation.

Due to the combined structure of various granulation skills in the granulation field, the granulation function of organic fertilizer is significantly enhanced, making organic fertilizer granulation one of the rapid, low consumption and promising granulation methods in modern industrial granulation. skill.

It is a unique advantage of similar fertilizer granulation equipment and has an advanced level in the production of organic fertilizer granulation.

How to make fertilizer granules at low cost? You Can Use

How much is the granulator? What is the price of fertilizer granulator? What should users do if they can’t operate, install or use the organic fertilizer manufacturing machine sx?

As an organic fertilizer equipment manufacturer, we provide trial production, type selection, installation of fertilizer raw materials, production guidance of granulator and other services.

In the process of organic fertilizer production, powder materials are transported to disc granulator by belt conveyor. The inclination angle is 50 ° The turntable rotates with the material. Like rotary drum granulators, disc granulators use wet granulation to shape particles.

When the material reaches a certain height, its gravity and inertia separate from the disc, slide along the bending path, and complete the rolling required by granulation under the action of force.

At the same time, the liquid sprayed by the spraying system is evenly sprayed on the rolled material to condense into particles, so as to complete the whole granulation process.

Granulator Selection for fertilizer pelleting process

Different types and series of organic fertilizer machines will be equipped during the fertilizer manufacturing process. It will be equipped with a fermentation compost dumper to complete the fermentation process, and will be equipped with fertilizer mixer, fertilizer different types of crusher to deal with raw materials. There, if we produce bio organic fertilizer into granulator, we can use fertilizer granulator to complete the granulation process, design the type of fertilizer granulator into different types, and choose the appropriate type of fertilizer granulator to complete the granulation process.

Bio Fertilizer Production Line
Bio Fertilizer Production Line

For example, in the organic fertilizer production line, we can use drum granulator, disc granulator and new type organic fertilizer granulator to complete the production process, We can use the roller granulator to produce NPK fertilizer by extrusion. In the process of bio fertilizer production, the flat mold granulator can be selected to complete the production process and complete the granulation process. Different types of fertilizer granulator can be used in different types of fertilizer production process, and its working principle is different.

The production technology and technology of bio organic fertilizer: the technology content of bio organic fertilizer production is relatively high. In the process of fertilizer production, different types and series of organic fertilizer machines are required to complete the production process.

In order to achieve the goal of directional maturity and deodorization, we must also add microorganisms with specific functions to improve the effect of products. At present, bio organic fertilizer has been listed in the category of microbial fertilizer in the world, and more strict management measures are implemented than organic fertilizer to promote the healthy development of organic fertilizer.

Powder and Granular Fertilizer Production Solutions

Organic fertilizer production line is designed to produce organic fertilizer granulator or powdery organic fertilizer, but what is the difference between powdery and granular organic fertilizer processed by organic fertilizer equipment?

As a part of granular organic fertilizer equipment, the main process means of powdery organic fertilizer equipment are as follows: fermenting organic fertilizer raw materials, livestock manure or domestic waste, sludge, grain, biogas residue, etc. After decomposition, comminution and mixing, packaging.

The basic process configuration of organic fertilizer equipment is dehydration, drying, fermentation, crushing, mixing and packaging. In this way, compared with the simple powder fertilizer technology, the processing of powder organic fertilizer can be completed. Granular organic fertilizer needs further processing. The basic process configuration of granular organic fertilizer machine is dehydration, drying, fermentation, crushing, crushing, granulation, cooling and packaging. After cooling, the granulator can package, store or sell the system and equipment for each process of organic fertilizer manufacturing process.
