INTRODUCTION
Rotary drum granulator is a molding machine that can make material into a particular shape.It is one of the key equipment of the compound fertilizer industry, which is suitable for cold or hot granulation and mass production for high and low concentration compound fertilizer. The main mode of work is granulation with wet material. Through a certain amount of water or steam, the basic fertilizer is fully chemically reacted in the cylinder after being humidified. In a certain liquid phase, the rotating movement of the barrel is used to make the extrusion pressure of the material into the ball.
We adopt special rubber liner or acid-resistant stainless steel liner into the rotary drum, and achieve the functions of automatic scars and tumor removal, so that the traditional scraper device can be cancelled. This machine has so many characteristics such as high balling strength, good looking, corrosion resistance, wear resistance, low energy consumption, long operation life, convenient operation and easy maintenance and so on.
FEATURES
1.The ball granulation rate is 70%, with small amount of return material, small size of feed back and can be re-granulation;
2.By steam heating, it can improve the temperature of material, so that the water is low after ball forming, thus improve the drying efficiency;
3.Using rubber engineering plastics as lining, the raw materials are not easy to stick, and play a role of anti-corrosion and thermal insulation.
4.It has the large capacity, low power consumption and maintenance costs.
Working Principle:
The main motor drives the belt and pulley, and transmits to the driving shaft through the reducer. The counter open gears that installed on the driving shaft engaged with the large gears that fixed on the machine body and work in opposite directions. The material enters the cylinder through the feed end. Through the processing of the special internal structure, make the materials into particles and finally flow out of the outlet. As the material continues to enter and continuous rotation of the granulator, it will be able to achieve mass production.
