Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field related to refractory material processing equipment, and specifically relates to an anti-clogging grinding mill for refractory material processing. Background Art
[0002] In the traditional sense, refractory materials are mostly identified by their refractoriness. Refractoriness refers to the Celsius temperature at which a conical sample of a refractory material can resist high temperature without softening and melting under no load. However, with the continuous development of science and technology, the definition of refractoriness alone can no longer fully describe refractory materials. Any material whose physical and chemical properties allow it to be used in a high temperature environment can be called a refractory material. Refractory materials are also widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, power and other industrial fields. In the preparation process of refractory materials, it is often necessary to operate the raw materials with toner. The grinding roller of the traditional refractory processing mill mostly adopts an integrated fixed design. When the grinding roller is damaged and needs to be replaced, it is time-consuming and labor-intensive, very troublesome, and its practicality needs to be improved.
