in the large ball mill, however, the wear rate increased about 10 times. apparently the larger mill produced impacts sufficient to remove the passivated film, thereby allowing an erosion-corrosion synergism. the data show that the large ball mill should give a more accurate correlation with industrial wet-grinding mills.
wet ball mill , energy saving ball mill ball mill, an energy-saving grinding device, is widely used in mineral processing, building materials and chemical industries. wet ball mill machine grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. the
9. reporting test results 9.1 report the wet ball mill value to the nearest whole number. note 3—this test furnishes valuable supplementary data pertaining to the quality of the aggregate portion of flexible base material. the wet ball mill test is more reliable than the los angeles abrasion test in evaluating the quality of base materials.
this test method describes a procedure for determining the resistance of the aggregate in flexible base material to disintegration in the presence of water. wet grinding in planetary ball
