Liming Heavy Industry's Multi-model Grinding Equipment Empowers the High-end Development of Dolomite Industry

Dolomite is an important calcium-magnesium resource, mainly composed of magnesite and calcite, with small amounts of clay minerals and chert, and sometimes gypsum, celestite, barite, pyrite, organic matter, etc. It is rich in resources and distributed across all provinces. The currently proven reserves can meet the needs of economic construction. China's dolomite ores have high contents of MgO and CaO, with higher purity and fewer impurities, making them high-quality raw materials for metallurgy, chemical industry, building materials, rubber, refractory materials and other industries. As a non-metallic mineral resource with great economic value and multiple development and utilization possibilities, the fine processing, efficient and rational utilization of dolomite are crucial.

To meet the requirements for dolomite fineness in different fields, Liming Heavy Industry has developed various models of dolomite powder making equipment, mainly including 80-400 mesh fine powder grinding equipment (LM Vertical Roller Mill, MTW European Trapezium Grinding Mill) and 400-3250 mesh ultra-fine powder grinding equipment (LUM Ultra-fine Vertical Mill, MW Ring Roller Micro-powder Mill).
