chemical compound fertilizer granulator in the fertilizer production line includes the following machines: fertilizer mixer machine → fertilizer crusher machine → rotary drum granulator →rotary drum dryer → rotary drum cooler→ rotary drum coater→ rotary drum screening machine →packaging machine → spraying granulating system→ belt conveyor → and other accessories.
Compound Fertilizer Production Line working principle
The process technology of N-P-K fertilizers is advanced and reliable. According to the compatibility and crossability of the three raw materials, N-P-K compound fertilizer in different percentage composition can be manufactured applicable for different requirements of soils and crops.
1. Firstly, the raw materials are put into mixer in strict accordance with the technical requirements of each raw material quantity. Then the conveying belt sends the materials to crushing machine.
2. Then, the crusher machine smashes lump materials into small ones that the fineness meets the required for granulation. Then the conveying belt sends the materials to rotary drum granulator machine.
3. During granulating, there is a water pump to offer gas and makes fertilizer granules forming easily. The solid fertilizer powder after granulating will rise by the rotation of the cylinder and scroll down under the effect of gravity. At the same time, according to the raw material quantity, add a certain proportion adhesives for granulation. After several times repetition of the same rotation, fertilizer materials gradually form. Next the conveying belt sends the materials to rotary drum drying machine and cooling machine.
advantages of compound fertilizer production line
1.The barrel body of this rotary drum pellet machine is made up of special rubber plate lining or acid-resistant stainless steel lining plate, thus automatic scar and burl removal is achieved. So the traditional scraper device is canceled in this rotary drum granulator.
2.This compound fertilizer production granulator features an attractive appearance, rational structure, high granulating intensity, good corrosive resistance, good abrasive resistance, low energy consumption, long service life, convenient operation and easy maintenance, etc.
3.This compound fertilizer production granulator is applicable to producing both of organic and inorganic fertilizers.
