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.

Power plants to use only quality, washed coal: Environment

24/07/2012 NEW DELHI: Power plants in urban and industrial areas can use only washed coal that is less polluting. The environment ministry has issued stringent notification effective from January 1, 2014 on quality of coal used for power generation. As per the notification, thermal power plants located beyond 500 km from the mine should use only treated coal that has gross calorific value below 4000 Kcal/kg.

Because the bulk density of the clean coal is less than that of the middlings/rejects, it is clear that the porosity of the former is higher than the latter. Higher screening velocity re-settles finer magnetite in the clean coal pores, thus increasing magnetite losses.
