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).

Flexible drive solutions for use in ball mills A ball mill is a horizontal cylinder filled with steel balls or the like. This cylinder rotates around its axis and transmits the rotating effect to the balls. The material fed through the mill is crushed by the impact and ground as a result of the friction between the balls.

Power required to drive a ball mill with a particular ball load is proportional to (where, D = diameter of ball mill )

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 …

Equation 1 to drive the corrected power requirement (Rowland, 1982). The equation for Third Theory of Comminution Bond's was originally developed for use with conventional crushing and grinding circuits (crusher-rod-ball mill or crusher-ball mill). By the 1970s, the application of conventional tended to be limited to relatively low capacities.

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

Equation 1 is multiplied by the factor of 1.08. A multi-compartment ball mill consists of two or more grate discharge ball mills in series. The same equation is used to calculate the power that each ball mill compartment should draw. The total power is the sum of the power calculated for each of the separate compartments.

The power required to drive a mill depends, to some extent on every one of the physical dimensions defining the mill shell and ball charge and on many of those defining the properties of the powder charge. Thus the number of variables involved is very large.
