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.
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.
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.

2018-1-4 Gold plating is very commonly used in different areas of techniques, for decorative purposes and corrosion protection. Electrolytes based on cyanide and ferrous cyanide solutions are still present in most of gold plating baths, in spite of large efforts to replace them by some less toxic substance. Gold plating from electrolyte based on cyanide is known as high-risk technology from ecological point of view. In this work the results of synthesis a new type of electrolyte based on gold complex on mercaptotriasole based are presented. Electrolyte itself is described elsewhere. The goal was to establish the optimal parameters for decorative gold plating for this type of electrolyte and compare the results with those obtained from cyanide electrolyte. The methods used were: recording of polarization curves to obtain limiting current densities, experiments in Hull cell and experiments in laboratory cell for gold plating. All experiments were performed with additives. The same experiments were conducted with the cyanide electrolyte
