Granite, quartz, basalt, pebble, limestone, dolomite, etc.

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.

However, there may be times during hot dry summers when the mill outlet temperature shoots up. This is also never a desired situation because of fire hazard. In fact, to combat this fire hazard, arrangements for mill-inerting systems with inert gases (e.g., N 2 and CO 2) need to be made (another purpose is to reduce air supply).

COAL HANDLING SAFETY AMETEK Land

The increasing use of sub-bituminous coals throughout the world has increased the risks of grinding mill incidents and silo fires. Good operating procedures, such as inventory turnover, nitrogen inerting or using chemicals reduce the risk of auto-ignition, however mill and silo fires may still occur.

Fire Detection Methods for Coal Pulverizer Systems

Fires on the grinding table and in the classifier can be either smoldering or open flames. Areas upstream of the classifier more often produce smoldering fires. A major problem of grinding subbituminous coals is a high probability of burning coal being fed into the mill from storage.
