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.

open pit mineral processing production

A new methodology for the open-pit mine production

processing cost is then equal to the value of the resulting mineral after processing minus the sales cost. Finding the OCOG is a bit more complicated because first, the opportunity cost of maintaining unexploited reserves has to be calculated, and then added to the processing cost. However, this value will automatically optimize the NPV and IRR.
