BALL MILL LINER HAVING BRICKS WITH WEAR
The extent of the wear of the liner 20 cannot be accurately determined by the length of time the ball mill is in use because the wear varies greatly As pointed out previously the degree of wear will depend on the type and amount of the charge and percent of solids as well as the size density hardness and quantity of the mill balls employed.
