Mechanical superfine grinding is one of the main processing technologies of superfine powder. It is of great significance to the development of non-metallic ore ultrafine powder industry because of the advantages of new equipment, chemical and ultrafine powder production expansion.

In ultra-fine powder deep processing technology, the main equipment is ultra-fine powder preparation equipment and classification equipment. HGM series ring roller micro-grinding is a kind of ultra-fine powder deep processing equipment launched by Liming Heavy Industry. The fineness can reach D97 ≤ 5μm at one time. It has been successfully applied to the deep processing of ultra-fine powder of non-metallic minerals such as ultra-fine heavy calcium carbonate, ultra-fine kaolin and ultra-fine talc.

Stable process, high fineness of finished products, low investment cost, high powder yield, low loss of parts, and environmental protection are the six major performance advantages of HGM micro-grinding, which help the industrial production of high-tech industries such as aerospace stealth materials, technical application ceramics, absorbing materials, functional fibers, environmental protection materials, and biomedical materials.
