A.working principle of DH650 granulator:

DH650 granulator makes use of paired rollers. With certain clearance (adjustable) between two rolls, the two rolls rotate in reversely in the same speed. Shaft holders of one group of rolls are fixed, and the ones of the other group can slide to help the hydraulic cylinder press the rolls for abutting closely against each other. Many arc grooves with the same shape and size are arrayed regularly on the roll surface. In accordance with different compressing ratios of target materials, the wave trough of arc groove of one roll shall be directed at that of one roll. When two rolls parallel each other horizontally, powder grained materials are, continuously and evenly fed in the clearance between two rolls by means of their gravities and through a forced charger from above of two rolls. After entering the nip area, the materials are gradually nipped by the rolls. With continuous rotation of the rolls, the space that the materials occupy reduces gradually and is compressed step by step and reaches the maximum shaping pressure. And then, as the pressure reduces gradually later, pressed blocks drop off the arc grooves of the rolls for recovered elasticity and gravity of the flaking machine and enter a crushing device for crushing and then enter a sieving device for sieving. At last, grained products are obtained.
