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.

Stimulation Techniques of Coalbed Methane Reservoirs

2020-7-10  Based on the phase transition of water, the liquid nitrogen technique is to inject the cryogenic liquid nitrogen into the coal seam to fracture coal medium and thus improve the coal permeability. In addition, the liquid nitrogen gasification and low-temperature effect can damage the coal and create the fracture so that the coal seam permeability increases.

Enhanced coalbed methane recovery ScienceDirect

2009-1-1  Abstract. The recovery of coalbed methane can be enhanced by injecting CO 2 in the coal seam at supercritical conditions. Through an in situ adsorption/desorption process the displaced methane is produced and the adsorbed CO 2 is permanently stored. This is called enhanced coalbed methane recovery (ECBM) and it is a technique under investigation as
