Description

Technical Field

[0001] The utility model relates to the technical field of feed pelleting, in particular to a ring die for a feed pelleting machine. Background Art

[0002] Feed is the general term for food for animals raised by humans. In a narrower sense, feed mainly refers to food for animals raised in agriculture or animal husbandry. Feed includes more than ten types of feed raw materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, oils, meat and bone meal, grains, feed additives, etc.

[0003] When preparing feed, a pellet mill is often used. The principle of the pellet mill is to pass the mixed raw materials through a die with holes to produce granular feed. The ring die is the key part of the pellet mill and is the most important vulnerable part in the pellet mill. According to statistics, the loss rate of the ring die accounts for more than 25% of the maintenance cost of the entire production workshop, and it has a direct impact on the quality of the extruded pellet feed. Most of the existing ring dies are installed in a split type. Different ring dies must be installed according to the model of the pelletizing equipment. This requires different pellet mills to purchase different types of ring dies, and the power rolling assembly of the pellet mill must be disassembled when installing the ring die, which is very cumbersome.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

The grinding roller 10 is installed outside the rotating shaft 15 through the eccentric shaft 20, so that the gap between the self-rotation of the grinding roller 10 and the inner wall of the fixed cylinder 1 when the grinding roller 10 revolves around the rotating shaft 15 can be continuously changed, and then the gap between the grinding roller 10 and the inner wall of the fixed cylinder 1 is automatically changed.
