European Type Jaw Crusher

European Type Jaw Crusher is a new crushing machine, the jaw crusher manufacturer, after the release of traditional jaw crusher. This jaw crusher is a perfect combination of modern science and technology and the production practice, which can better satisfy the automatic production demands of vast customers.

Input Size: 0-930mm
Capacity: 12-650TPH

Materials:
Granite, marble, basalt, limestone, quartz, pebble, copper ore, iron ore.

VSI6X Series Vertical Crusher

Due to the increasing market demand for the scale, intensification, energy conservation, environment protection and high-quality machine-made sand, a Chinese professional sand maker manufacturer, further optimizes the structure and function of traditional vertical-shaft impact crushers and launches a new generation of sand-making and reshaping machine with high efficiency and low costs --- VSI6X Series Vertical Crusher.

Input Size: 0-50mm
Capacity: 100-583TPH

Materials:
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.
