How to work the drum granulator?

The working principle of this series of rotary drum granulator is: the main motor drives the belt and pulley, which are driven to the transmission shaft through the reducer, and work together through the open shaft installed on the gear and the large gear teeth fixed on the body.

The material is fed from the feeding end through the cylinder. Through the function of the internal structure of the cylinder, the particles are made and finally come out through the air outlet. With the continuous entry of materials, the continuous rotation of granulator, in order to achieve mass production.

Drum granulator is a kind of molding machine which can make material into specific shape. It is one of the key equipments in NPK fertilizer production line. The granulation rate is 70%. There is a small amount of return material. The particle size of return material is small and can be granulated again.

It is suitable for large-scale production of cold and hot fertilizer granulation line and high and low concentration compound fertilizer line. The main working method of aggregate wet granulation is to make the fertilizer fully wet in the cylinder through a certain amount of water or steam, and then rotate the cylinder under a certain liquid condition to make the particles agglomerate and produce the pressure of material extrusion into balls.
