LM Vertical Mill

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

Large capacity, Low consumption, Environmental friendly

MTW European Trapezium Mill has a large market share in the grinding industry. Whether bevel gear overall drive, inner automatic thin-oil lubricating system or arc air channel, these proprietary technologies makes machine advanced, humanized and green.

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

nihil molestiae consequatur

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.

Original Research Impact of Underground Coal Mining on

China is one of the largest coal producers in the world and coal production in 2014 was 3.87 billion tons. But more than 92% of the coal comes from underground mining, causing a large area of surface subsidence. It is estimated that extracting 10 kilotons of coal is associated with subsidence of 0.20-0.33 hm2 of land on average. A conservative estimate of greater than 100 × 104 hm2 of land had subsided by the end of 2013 due to coal mining, and subsidence in this area is still increasing at a rate of 3.0-4.7 × 104 hm2 per year. Coal mining collapse has destroyed the original water system and vegetation, and the physical and chemical properties of soil have been changed, which caused the heterogeneity and fragmentation of landscape structure. Also, coal mining collapses lead large arable lands to become desolate marshes [17, 33]. It is obvious that coal mining collapse has greatly damaged the landscape of the coal
