In discussions on high energy ball milling, the more generic term ball mills is often used in place of the terms stirred ball mills or attritors, but the differences between the types of mills are quite distinct. and, depending on your application, you may find that one type of high energy ball milling is more appropriate for.
Ball mill working principle high energy ball milling isype of powder grinding mill used to grind ores and other materials to 25 mesh or extremely fine powders, mainly used in the mineral processing industry, both in open or closed circuits. ball milling isrinding method that reduces the product intoontrolled final grind and a.
Ball mills giveontrolled final grind and produce flotation feed ofniform size. ball mills tumble iron or steel balls with the ore. the balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds. the feed to ball mills dry basis is.
The main part of the ball mill mainly include feeding part, discharging part,otary part,ransmission part reducer, small gear, motors, electrical control and other parts. hollow shaft adopts steel castings, the liner is detachable, slewing gear hobbing with casting, the cylinder body with wearresistant liner, with good resistance to wear.
