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, coupling-end 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.
The mill used for this comparison is a 4.4-meter diameter by 13.6 meter long ball mill with a 5000 HP drive motor. It is designed for approximately 90 s.ton per hour. This type two-compartment mill is a state- of-the-art shell supported cement finish mill. The torque and time requirements of the mill with the ball
BALL & ACME LEAD SCREW TECHNICAL INFORMATION This section will introduce most of the more common types of drive mechanisms found in linear motion machinery. Ideally, a drive system should not support any loads, with all the loads being handled by a bearing system.
Ball Mill Drives. We can provide all elements of a mill drive system as a fully optimised solution to suit your process exactly, or individual mill drive gearboxes, girth gears, pinions and couplings as required.
Ball mill. A typical type of fine grinder is the ball mill.A 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%.
