Ball mill, Grinding machine, Wet ball mill, Dry 21.05.2014· Ball mill is used to grinding ores or other materials after crusher, it is the mechanical equipment for getting finer particle products.

(PDF) Selection and design of mill linersThe appropriate design of liners continues to be an issue on many mills worldwide. Loss of milling capacity especially at liner change, uneven wear lives along the mill, substantial scrap on worn

Hammer Mill: components, operating principles, types, uses Disadvantages of Hammer Mill. 1. Not recommended for the fine grinding of very hard and abrasive material due to excessive wear. 2. Not suitable for low-melting sticky or plastic-like material due to heat generation in the mill head as a result of mill fouling. 3. The mill may be choked if the feed rate is not controlled, leading to damage. 4.
