overflow ball mills and grinding ball mills. By using special alloy steel segments moulded into rubber, composite plates greatly reduce the liner breakage risk, present in the grinding process where balls of over 100mm are used. In addition, composite linings are up to 35-50% lighter than their metal equivalents. This translates into an
Ball Mill Grinding Theory
The classifier delivered 33 T. of sand per hour. The total ball-mill feed was therefore 40.37 T. per hr. or 550 per cent, of the original feed. Two Stage Grinding. The object of these tests was to determine the capacity of ball-mills when crushing in two stages. The conditions of the test were as follows: First Stage of Ball Milling
The Selection and Design of Mill Liners
Greatly accelerated liner wear due to high-energy impacts on the liner. For a 5m diameter mill these will be in excess of 8m.s-1, for a 10m diameter mill these exceed 12m.s-1. This causes high chrome liners to spall and crack and they may even fracture. This can reduce liner life from a year to less than a few months.
