For the mining industry, our semi-autogenous (SAG) grinding mill uses a minimal ball charge in the range of 6-15 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding media.

Plasma cutting - Function, advantages and disadvantages

Jun 25, 2019· Plasma cutting is an effective way to cut thin and thick materials. Hand torches can usually cut up to 38 mm thick steel sheet, stronger computer controlled torches can cut up to 150 mm thick steel sheet. Since plasma cutters produce a very hot and very localised "cone" for cutting, they are very useful for cutting and welding sheets in curved or angled shapes.
