Description

Technical field

[0001] The invention belongs to the field of food processing, and particularly relates to a rice milling wheel and a preparation method thereof. Background technique

[0002] The rice milling wheel is an important part of the rice mill, which directly determines the precision of the grains milled. There is a resin rice polishing wheel in the prior art, which is made by mixing phenolic resin and epoxy resin as a bonding agent with abrasives. In the process of preparing the resin rice polishing wheel, the raw materials are not easy to mix and the bonding agent is easy. Agglomeration causes uneven hardness of the rice milling wheel, which is easy to fall off during use, which affects the accuracy of the processed rice and has a short service life; and because the abrasives such as silicon carbide used are high energy consumption, high pollution and resources Because of its high cost, heavy pollution and consumption of national resources. Summary of the invention [...
