The pellet cooler is used to reduce the high temperature of pellets who just come out from the pellet mill to above room temperature. It plays an important role in large pellet mill plant because the cooling process guarantee pellets production continuously.
Press capacity depends substantially on pellet quality (stability according to the PDI, Pellet Durability Index). The durability of pellets shall be determined by tumbling the test sample for 10 seconds at 500 rpm, in a dust-tight enclosure.
Various types of dies are used by the feed manufacturing industry. Die thickness is a factor in the production of high-quality pellets and must be accurately balanced with the formulation and conditioning.
