Description

Technical Field

[0001] This utility model relates to the field of grinding equipment, and more specifically, to a grain grinding device. Background Technology

[0002] In the grain processing industry, grain grinding is a crucial step that directly affects the quality of the final product and production efficiency. Fixed grinding structures often result in uneven distribution of grain within the grinding cylinder, with some grains failing to fully contact the grinding components and thus remaining under-ground, affecting the fineness and uniformity of the product. Secondly, traditional grinding devices are prone to accumulation and clogging during the grinding process, especially at the bottom and corners of the grinding cylinder. This not only reduces grinding efficiency but also increases the difficulty of cleaning and maintenance. Furthermore, adjusting the grinding fineness using traditional devices is cumbersome and difficult to achieve precise adjustments, failing to meet the diverse needs of different users for grain fineness.
