Grinding roller device for grain

Abstract

The invention discloses a grinding roller device for grain, which comprises a roller body, a roller shaft, a non-metallic abrasive and a manual water pump. The outer wall of the roller body is provided with a roller shaft, which is fixedly connected with the roller body. There are non-metallic abrasives, and the non-metallic abrasives are embedded in the roller body. There is a manual water pump on the right side of the roller body. The manual water pump is set through the nesting of the roller shaft and the roller body. The neck is fixedly connected with the roller body, bearing seats are arranged on both sides of the roller shaft, and the bearing seats are embedded in the roller shaft. The grinding wheel made of corundum has high hardness, good heat resistance and certain toughness. It can cut the grain and make it easier to crush the grain. There is a water distribution pipe in the roller body. Water circulation is carried out in the roller body, thereby reducing the temperature in the grinding roller, reducing the heat in the roller body, so that the grain maintains the original nutrient content, and the nutrient substance will not be decomposed at high temperature due to the high temperature of the grinding roller.

Description

technical field [0001] The invention relates to the technical field of grain processing and production equipment, in particular to a grinding roller device for grain. Background technique [0002] The miscellaneous grains mill is a machine that grinds various grains, Chinese medicinal materials and other foods into uniform powders of 50-200 meshes. The grinding roller is the most important part of the grain milling machine, and the grinding roller needs to have good wear resistance in order to facilitate the grinding and processing of grains and miscellaneous grains. [0003] However, during the grinding process of the existing grinding roller device, the grinding roller is seriously worn due to the comprehensive interaction of forces such as the rolling pressure of the roller, the reaction force of the material, and the frictional resistance between the material and the lining plate of the grinding roller. There will be impact and collision between the body and the liner, ...

Problems solved by technology

[0003] However, during the grinding process of the existing grinding roller device, the grinding roller is seriously worn due to the comprehensive interaction of forces such as the rolling pressure of the roller, the reaction force of the material, and the frictional resistance between the material and the lining plate of the grinding roller. There will be impact and collision between the body and the liner, which will cause the grinding roller to crack or even break due to the increased wear between the body and the liner, causing the liner to fall off and the machine to be damaged. The outside of the grinding roller usually has a circular structure, which cannot be completely Grinding the grains, the rolling effect is not good enough, and the advanced grinding roller device generates a lot of heat energy due to friction during the grinding process, and the heat energy stays in the roller body for a long time, which will easily increase the temperature of the grinding roller and make the nutrition of the grain Components are converted and lost due to pyrolysis
