Pellet Mills China
Ring Die Pellet mills
The process of pelleting consists of forcing a soft material through holes in a metal die plate to form compacted pellets which are then cut to a pre-determined size. The machinery which has been developed for this purpose is now very diverse in design and there is much controversy between different equipment manufacturers as to which type is the most effective. Most pellet mills now 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.
Usually the die plate itself rotates, and on its outer-side stationary knives cut the pellets to a pre-set length. From there, they are transferred to a cooler/drier to remove the heat which is generated during the pelleting process or is often added during steam conditioning. The moisture content of the pellets also needs to be reduced for proper storage.
