The GM series Ring Die Pellet Mills are large in size and capacity than flat die pellet mill, which are usually for commercial and industrial use. Ring die pellet press is more cost-effective for mass production, as a part of big or middle-sized pellet plant for making animal feed or biomass fuel.

Ring Die Pellet Mill Working Principle

The process of pelleting press consists of forcing the soft material through holes in a metal die ring to make compacted material into formation of pellets, which are then cut to a pre-determined size by cutter inside of rings. The machinery related pelleting press which has been developed for this purpose is very diverse in design now. There is much controversial point between different pellet press manufacturers on which type of pellet mill is the most effective. Now, most ring die pellet mills have one or more conditioning units mounted above them where liquids such as water can be added to improve pelletability. The water is sometimes added in the form of steam, resulting in firmer pellets produced.

Usually the ring die plate rotates itself, and on its outer-side stationary knives cut the pellets to a pre-set length. From there, they are transferred to a cooler or drier to remove the heat generated during the pelleting process or added during steam conditioning. The moisture content of the pellets also needs to be reduced for better storage after processing by ring die pellet mill.
