Apr 28, 2020· In the beneficiation operation, the steel balls have a great influence on the grinding. Good steel The ball will achieve a good grinding effect, and the poor steel ball will even seriously affect the grinding efficiency. For grinding balls of the same specification, the greater the specific gravity (ie density), the better the grinding effect.
Sep 10, 2020· Ratio of grinding mill loading by grinding balls. Ratio of grinding balls volume to mill working volume is calculated by the formula: where: G н – mass of grinding balls, kg; γ – apparent density of grinding media, kg/m3; L – drum length, m. Apparent density of grinding media depends on ball diameter and density of the material.
Mill Type Overview. Three types of mill design are common. The Overflow Discharge mill is best suited for fine grinding to 75 – 106 microns.; The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 – 250 microns.; The Center-Periphery Discharge mill has feed reporting from both ends and the product discharges ...

sticky and the ball charge expands. The balls become coated and the grinding efficiency decreases. The pilot mill is also equipped with a sensor measuring the 'ball and pulp toe and shoulder angles' (see Figure 3). These data are then used to calculate the total pulp and ball charge angle (see Graph 5).
