in variable speed mills, this may be achieved by reducing mill speed; and in both cases this may be achieved by design by increasing the lifter face angle. Traditionally, the number of shell lifters used in a SAG mill is equal to twice the number of the feet in the mill shell diameter (, a 34ftdiameter mill shell would have 68 shell lifters).

For 60 mm (″) and smaller top size balls for cast metal liners use double wave liners with the number of lifters to the circle approximately D in meters (for D in feet, divide D by ). Wave height above the liners from to 2 times the liner thickness. Rubber liners of the integral molded design follow the cast metal design.

Process Optimization Specialist A ball mill is one of the most common equipment items in a mineral processing plant. Its job, to grind rock by tumbling it in a large metal cylinder loaded with steel balls, is highly energy intensive. In fact, the cost of grinding in a mining operation represents a significant proportion of the total energy cost.
