Composite Pulpmax Mill Liners Can Lower Costs And

Using composite liners also cuts the weight of the liners to about 50 percent of standard steel cast liners, making it possible to work with a higher ball charge level without increasing the total weight of the mill. Both of these benefits result in a higher throughput. The higher throughput must be considered over longer periods of time.
