Description

Technical Field

[0001] The utility model relates to the technical field of feed processing equipment, in particular to a feed extrusion die. Background Art

[0002] Feed refers to animal food, usually including grains, soybean meal, yeast, oil, minerals and vitamins, etc. These foods can be used to prepare different types of feed to help animals grow, reproduce and stay healthy. After being cleaned, crushed and mixed, the raw materials of the feed will be pelletized by pelletizing equipment;

[0003] Feed pellet mills usually include steam boilers, conditioners, pellet mills, coolers, grading screens, crushers and other equipment. They can extrude raw materials and extrude them into pellets through a die. The die inside is a ring die. During pelleting, the raw materials are squeezed into the gap between the ring die and the roller in the pellet mill. Therefore, the roller in the pellet mill squeezes the raw materials into the inner side of the ring die with a large pressure. Since the gap between the roller and the ring die is small, after a period of use, the pressure surface on the inner side of the ring die and the roller will be offset and contact the inner side of the ring die, which will cause wear and structural changes on the inner side of the ring die. Therefore, when replacing the ring die, the entire ring die needs to be replaced, which makes it impossible to continue to use other intact areas of the ring die, resulting in a certain amount of material waste. At the same time, the maintenance and replacement costs of the ring die cannot be reduced. Utility Model Content
