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.

Direct-Reduced Iron an overview ScienceDirect Topics

Jan 05, 2012 The DRI product is continuously discharged from the reactor and fed into a subsequent smelting reduction process. This can either be a shaft furnace, a submerged arc furnace or a smelting reduction process like HIsmelt (Orth et al., 2004), Fig. 12.14, or Auslron (Laumann et al, 2010). The carbon content of the material is 6–8%.

Direct Reduced Iron (DRI) Refractories Resco Products

Direct Reduced Iron (DRI) Refractory Direct Reduced Iron (DRI) is an alternative to the blast furnace processes to produce a source of iron units. Greater availability of natural gas has replaced classic coke oven coal-based processes. Several processes are commercially viable today and they use a number of ways to achieve good quality DRI.
