1.Vertical feeding, directly in pelletizing
room, Die is static, rollers rotate; material are evenly
distributed around pelletizing room because of centrifugal force,
no block.
2.Double-layer die. Two layers both can be used
for reduce the cost. High efficiency and save energy. Pelletizing
room is also used for cooling, more options, and more
gains.
3. Independent and frequent conversion
discharge device can ensure the formation rate of
pellet.
4.Ring die and vertical structure are good for
cooling the pelletizing room.
