How to choose dry and wet ball mill. 1. Correctly choose the feeding way of dry grinding and wet grinding. Whether feed the material dry or wet depends entirely on the subsequent operations in the ball mill and the nature of the produc Some materials require dry grinding because they will undergo physical or chemical changes after adding water.
— The feed enters one end of the ball mill, and discharges out the other end. Ball mills vary greatly in size, from large industrial ball mills measuring more than 25 ft. in diameter to small mills used for sample preparation in laboratories. Rod mills are similar to ball mills and use metal rods as the grinding media. Pebble mills use rock ...
