The spindle, driven by the motor, drives the press roll to rotate. The raw materials are ripened at high temperature between the press roll and the die plate. The particles are sent out of the machine from the die hole under the extrusion of the press roll. The forming length of the particles is adjusted by the size of the aperture notch in the die plate. The natural ripening temperature is about 70 ºC. The particles formed by the granulation have smooth surface, high hardness and can be stored for a long time.
