Vertical Ring Die Pellet Machine

详情

Applicable Raw Material
Raw materials which are hard to be bonded and shaped such as like husks (rice husk, sunflower seed husk, peanut shell etc), Wood scraps( branches, trunks, barks, sawdust etc) , crop straw, eucalyptus, palm thread, coffee husks, cocoa husks etc.
 
Working Principle
This machine adopts two-stage-drive system. The transmission shaft is connected to the principal axis via belt pulley, which enables the pinch roller to roll the internal surface to complete the pressing process.
 
During the process, raw material fell on the rotating plank through the feeding hole, then equispaced on the surface of the die inner cavity via rotation of the plank. After rolling by pinch roller, the powdery material will go through the die hole under the effect of high pressure and high temperature. During this process, the material will turn into cylindrical solid form under physical change and some chemical change. This cylindrical solid form will grow longer and longer through the hole until it was cut by the blades equispaced around the die, then the pellets take shape. The pellets will be collected to the discharge hole by the ejecting device, then fall down under gravity. Until now, the whole process of the pelletizing finishes.
