INTRODUCTION
Rotary drum granulator is the main equipment of compound fertilizer production line. It is the latest generation of rotary drum granulator developed by absorbing and digesting advanced technologies at home and abroad and combining with specific working conditions of relevant industries in China. It is suitable for granulation technology of various materials. His working principle is through a certain amount of water or steam, the basic fertilizer after humidification fully chemical reaction in the cylinder. Under a certain liquid phase condition, the extrusion pressure of the material enters into the ball by rotating the cylinder.
FEATURES
1.The rotary drum granulator uses steam to heat and adjust humidity, which improves the temperature of granulation material itself, reduces the granulation water content, reduces the dryer load and improves the working efficiency;
2.The pelletizing rate can reach 70%, and the equipment is easy to operate, flexible and easy to maintain;
3.It adopts 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 you can cancel the traditional scraper device.
4.The phenomenon of material sticking to the wall is eliminated, the labor intensity of workers is reduced, and the service life of the equipment is greatly prolonged.
5.The machine has the advantages of high ball forming strength, good appearance, corrosion resistance, wear resistance, low energy consumption and long service life.
WORJING PRINCIPLE
The main motor drive 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 into 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.
