Description

TECHNICAL FIELD

[0001] The utility model belongs to flour mill grinding roller processing technical field, especially related to a grinding machine for flour mill grinding roller processing. BACKGROUND

[0002] The flour mill grinding roller is a key component in the flour mill, which is usually made of high-quality steel and has certain hardness and wear resistance. The grinding roller is divided into two parts and is in the shape of a cylinder. It is installed at a specific position of the flour mill. During the flour processing, grains such as wheat enter the flour mill through the feed inlet and are transported between the two grinding rollers. The grinding roller surface usually has a specific texture or tooth-like structure. When the grinding roller rotates, the grains are crushed, ground, and turned into different products such as flour and bran through the extrusion, friction, and shearing action between the two grinding rollers. The rotational speed, gap, and surface texture of the grinding roller will affect the processing quality and yield of the flour. Different types of flour mills may use grinding rollers of different specifications and designs to meet different production needs.

[0003] During the processing of the flour mill grinding roller, polishing is an important process. Polishing mainly involves fine processing of the grinding roller surface. Through specific polishing processes, professional polishing equipment and materials are used to remove fine scratches, rough parts, and impurities generated during production and processing. After polishing, the grinding roller surface is smoother and more even, which helps to improve the performance of the grinding roller during flour processing. A smooth surface can reduce the frictional resistance between the grains and the grinding roller, making the flow of grains between the grinding rollers smoother and improving the production efficiency of flour. At the same time, polishing can also improve the wear resistance and corrosion resistance of the grinding roller, prolonging its service life. In addition, good polishing can also help to improve the quality of flour and reduce the increase in impurities in flour caused by uneven grinding roller surface.

[0004] In the current grinding roller processing flow, polishing is an indispensable link. However, the current polishing method has many drawbacks. In general, the polishing process requires manual polishing with a polishing machine, which greatly depends on human labor. Not only is the labor intensity high, but the overall polishing efficiency is also low. On the other hand, although there are some automatic polishing devices on the market, they are not satisfactory in actual use. They often require manual adjustment of the grinding roller, which cannot achieve automatic polishing of the outer surface of the grinding roller. This makes it difficult to effectively improve the overall polishing efficiency and meet the needs of modern high-efficiency production. Therefore, it is urgent to improve the polishing process of the grinding roller. UTILITY MODEL CONTENTS
