LM Vertical Mill

 limestone dust explosion

High drying efficiency, Low running cost, Good environmental effect

LM Vertical Mill integrates crushing, drying, grinding, classifying and conveying together, and it is specialized in processing non-metallic minerals, pulverized coal and slag. Its coverage area is reduced by 50% compared with ball mill, and the energy consumption is saved by 30%-40% similarly.

Applications: Cement, coal, power plant desulfurization, metallurgy, chemical industry, non-metallic mineral, construction material, ceramics.

MTW Trapezium Mill

limestone dust explosion

Little abrasion wear, Long service life

Based on 30 years of development experience of grinding equipment, LM Heavy Industry produced LUM Series Superfine Vertical Roller Grinding Mill to make ultra-fine powder. The grinding roller doesn't contact with millstone usually, which makes abrasion little and service life longer.

Applications: Superfine dry powder of none-metal ores such as calcite, marble, limestone, coarse whiting, talc, barite and dolomite and so on.

How Does Limestone Rock Dust Prevent Coal Dust

2012-8-30  In a coal dust explosion, the limestone rock dust may undergo thermal decomposition into cal­ cium oxide and carbon dioxide as shown by Equation 1. However, some of the calcium oxide may react with water vapor to give calcium hydroxide (Equation 2). Therefore, it is important to remove this ambiguity by converting any
