Main difference between flat die and ring die:

Flat die pellet mill is easy to clean because it can be access to the pelleting chamber in a short time that we can save a lot of time in change the die or the roller when they are worn. The design of flat die pellet mill also decides that it is more suitable in small-scale pellet production especially produce soft raw material.

Ring die pellet mill will not cause uneven die and roller wearing, which indicates that the cost in maintain and repair roller and ring die are considered lower. The other advantage is ring die pellet mill is more energy efficient.

1.Price. The price of ring die pellet mill is much higher than flat die pellet mill.

2.Feeding material way. Flat die pellet mill machine relies on material own weight entering into pressing chamber vertically, while ring die pellet mill machine adopts curve feeding trough rolling compression feed and high speed rotating into the compression bin.

3.for materials, but both of them can process animal feed,and wood sawdust pellets.

4.Capacity.
