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.

Edward Wilson Davis Wikipedia

Edward Wilson Davis (May 8, 1888 December 3, 1973) was an American engineer and inventor famous for pioneering early research into taconite. As a researcher at the University of Minnesota, Davis developed an engineering process to economically extract iron ore from hard taconite rocks, making taconite valuable as iron ore for the iron and steelindustries. He worked closely with industrial firms such as the Mesabi Iron Company and the Reserve Mining Company to transform his research into a working in

Taconite is a hard, flint-like type of rock containing low-grade iron ore. Vast reserves of taconite were discovered in Minnesota in 1870, but while high-grade natural iron ore was plentiful, taconite was considered waste rock and not used because extracting the iron was difficult and costly.

05/05/2020 Vast reserves of taconite, with iron concentrations of 30-50%, were discovered in 1870 near present-day Babbitt, on the Mesabi Iron Range. However these deposits were passed over in favor of mining existing high grade iron ore formations, because extracting the pure iron from taconite was extremely difficult and costly. In the 1940s, years of experimentation led by professor E.W. Davis at
