A reasonable working estimate to use in the case of gear and pinion drives would be 6 7%, ie the estimated power at pinion would be about 6 7% lower than the gross power draw. Gearless drives are quite different to gear and pinion drives.
In general, ball mill grinder can be fed either wet or dry, the ball mill machine is classed by electric power rather than diameter and capacity. JXSC ball mill manufacturer has industrial ball mill and small ball mill for sale, power range 18.5 800KW.
Today, the largest ball mill in operation is 8.53 m diameter and 13.41 m long with a corresponding motor power of 22 MW . View chapter Purchase book Sampling Theory and Methodology
Such mills are usually called pebble mills, but the working principle is the same as for ball mills. As the power input is approximately directly proportional to the volume weight of the grinding media, the power input for pebble mills is correspondingly smaller than for a ball mill.
Ball mills are rated by power rather than capacity. Today, the largest ball mill in operation is 8.53 m diameter and 13.41 m long with a corresponding motor power of 22 MW . View chapter Purchase book Manufacture of Portland Cement
In general, the ball volume of the ball mill steel ball is lower than the horizontal line in the cylinder. It is better to control the ball amount at about 40 50%. For smaller ball mills, the ball balls accounts about 35% at best, this can effectively ensure that the steel ball can fall freely, so that creates a larger impact force.
If P is less than 80% passing 70 microns, power consumption will be. Ball Mill Power Calculation Example. A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work ...
