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.

EXPLORING HPGR TECHNOLOGY FOR HEAP LEACHING

2014-10-1  promote the application of HPGR prepared Heap Leach processing for large tonnage projects are presented in the paper. Of note is the potential dual use of the crushing circuit for both the main CIL/P plant and the heap leach. HPGR has been shown to influence the extraction and kinetics of leaching low grade gold ores.

Crushed ore agglomeration and its control for heap

2013-2-1  It is possible to heap leach gold locked in some sulfide ores by adopting a bio-oxidation pretreatment followed by heap leaching. When gold is locked in other minerals exposure and leaching is possible by fine crushing using HPGR . Leaching size requirements and economic considerations dictate the complexity of the crushing plant.

2016-12-27  Fig. 3. Heap leach recovery vs. crush size At the end of the simulations, 80% of -4.65 mm crushing product target with 55.4% -3.35 mm was achieved with the capacity around 200 (±10%) Mg/h. Particles having 3.35 mm was the leach size for the best recovery. Figure 3 shows the heap leach recovery versus crush size for the process.

A novel sequential heap leach process for treating

2014-1-1  This process is followed by heap reclamation, a water wash step and re-stacking of the heap onto a new pad for a high temperature cyanide leach, achieved via solar heating of solution, to extract precious metals (Pt, Pd and Au) (Eksteen et al., 2012). Additionally, it is proposed that solar heating should be used to heat up the wash water used
