Ball mill. A typical type of fine grinder is the ball slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.

BALL MILL DRIVES, LOADED, WAVEFORM LEVELS, SEPTEMBER 1A 1B • Above is a plot of the waveform vibration levels at both the 1A 1B ball mills when loaded (acceleration). • Note how waveform levels at 1A ball mill are higher than that at 1B ball mill for every measurement and especially at points PIH PIA (pillow block, couplingend bearing).
In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.
Jan 01, 2018· For a specific load and operating conditions, the torque appearing in a tumbling ball mill is a highly variable magnitude in the time domain. This fact is due to the operating principle of ball mills, which is based in the elevation process of balls and material from the toe region to .
