Grinding media is grinding feed; High capacity (short retention time) Sensitive to feed composition (critical size material) Semi-Autogenous Grinding (SAG) Mill. Wet or dry; Higher capacity than A-G mill grinding; Primary, coarse grinding (up to 400 mm feed size) Grinding media is grinding feed plus 4-12% ball charge (ball dia.100- 125 mm)

what are the requirements for ball mill testing, start and

Oct 09, 2019 · Half-load test run: the filling rate of the medium in the ball mill cylinder is about 20-30%, and appropriate materials and water are given for a continuous test run of 8-10 hours. Full load test: after the half-load test and everything is normal, add enough medium inside the ball mill cylinder (gradually increase the ore amount) and run at

ball mill parameter selection & calculation - power

Aug 30, 2019 · 1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), the degree of
