To run a proper test, a representative sample of 50 pounds minimum is required. The sample for an impact crushing test should be no finer than 2″. The sample for a rod mill grindability test should be no finer than 80% passing ″, and the sample for a ball mill grindability test should be no finer than 80% passing 6 mesh. REFERENCES
A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 50 % of the mill volume and its size depends on the feed and mill size.
Introduction. The ball mill abrasion test (BMAT) is an industriallyrelevant multipurpose wear test method that enables tribologists and abrasion scientists to study the abrasive wear behaviour of materials for various service applications, particularly for grinding balls and mill liners, under conditions and contact mechanics very similar to the industrial ball mills.
Ball mill： Ball mills are the most widely used one. Rod mill： The rod mill has the highest efficiency when the feed size is <30mm and the discharge size is about 3mm with uniform particle size and light overcrushing phenomenon. SAG mill: When the weight of the SAG mill is more than 75%, the output is high and the energy consumption is low ...
Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually times the shell diameter (Figure ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 2040% water by weight.
