What is the working principle of the rotary drum granulator?

The rotary drum granulator drives the belt and pulley by the motor, passes to the drive shaft through the reducer, and synchronizes with the passive shaft through the split gear and works in reverse. Various powdered organic fertilizers are added from the hopper at the top of the granulator equipment. After degassing and spiral preloading, two equal rollers are entered. The rollers rotate relative to each other and the material is pressed into the space between the two rollers. The roll bites the material into the roll. Forced compression through gaps. After the material passes through the compression zone, the surface tension and gravity of the material allow it to come out naturally.
