NPK fertilizer manufacturing is the processing of powdered raw materials into pellets, which are composed of several NPK fertilizer production units
1.Automatic batching machine
Static automatic dosing system for fertilizer production need to be quantitative dosing of raw materials, the machine is mainly composed of feeding system, weighing device, silo, conveyor belt, etc., a high degree of automation, only manual feeding.
2.Belt conveyor
Industrial belt conveyor according to the principle of friction drive movement, suitable for conveying powder, granular, small block of low grinding and polishing materials and bagged materials, such as coal, gravel, sand, cement, fertilizer, food and so on.
3.Mixer
The double-shaft mixer is suitable for continuous mixing of mixed fertilizer powder, generally used after the automatic batching equipment of organic fertilizer and NPK compound fertilizer production line.
4.Crusher
Chain crusher is mainly used for the crushing of fertilizer raw materials, lump materials in the production of compound fertilizer, granular semi-finished products in NPK fertilizer production line, especially for raw materials such as superphosphate, ammonium phosphate, nitrate phosphate and so on.
5.Rotary drum granulator
Drum granulator can process organic fertilizer, compound fertilizer, biological fertilizer and other granular fertilizer, in the production process has irreplaceable advantages, drum granulator series is a fertilizer manufacturer necessary fertilizer granulator.
6.Dryer
Rotary cylinder dryer is mainly used for the production of compound fertilizer, drying a certain temperature and particle size of fertilizer, can also be used to dry other materials.
7.Cooler
The rotary cylinder cooling machine is used to cool the fertilizer with a certain temperature and particle size in the production of NPK compound fertilizer, and is used with the dryer, which can greatly improve the cooling speed, reduce labor intensity, increase output, further remove part of the water, and reduce the temperature of compound fertilizer particles.
8.Screening machine
The roller screening machine is widely used in the separation of bulk and granular raw materials such as compound fertilizer, organic fertilizer, nitrogen, phosphorus and potassium fertilizer, and can be equipped with a beating device to prevent screen hole clogging, and the screening efficiency is higher.
9.Coating machine
The complete equipment of fertilizer coating machine is composed of screw conveyor, stirring tank, oil pump, main engine, etc., which can effectively prevent fertilizer caking.
10.Automatic packing machine
The roller screening machine is widely used in the separation of bulk and granular raw materials such as compound fertilizer, organic fertilizer, nitrogen, phosphorus and potassium fertilizer, and can be equipped with a beating device to prevent screen hole clogging, and the screening efficiency is higher.

Advantages:
NPK fertilizer production line equipment has wide adaptability to raw materials, not only for granulation of compound fertilizers, but also for granulation of various raw materials such as medicine, chemical industry and feed.
NPK fertilizer production line adopts aggregate method. The main NPK fertilizer equipment are rotary drum granulator (or disc granulator), rotary dryer, drum screening machine, coating machine and chain crusher.
As a manufacturer of compound fertilizer equipment for many years, according to the research and development of our factory for many years, the NPK fertilizer production process can change the formula according to the soil and crops in different regions, which is conducive to improving the quality of agricultural products and improving the utilization rate of chemical fertilizers.
