Power Measurement: the only accurate way to measure mill power is to directly measure power or torque input to the shaft Indirect measurements are inaccurate and will underestimate mill power (Nesset, JE et al, Assessing the Performance and Efficiency of Fine Grinding Technologies, 38th Annual Meeting of the CMP, Canada, January 2006)
The specific rates of breakage of particles in a tumbling ball mill are described by the equation S i = ax α i (Q(z), where Q(z) is the probability function which ranges from 1 to 0 as particle size increasThis equation produces a maximum in S, and the particle size of the maximum is related to ball diameter by x m = k 1 d 2The variation of a with ball diameter was found to be ,

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 IsaMill is a stirred-medium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older high-throughput mills (such as ball mills and rod mills) Stirred mills often consist of stirrers mounted on a rotating shaft located along the central axis of the mill
Apr 07, 2015· a milling material: agate, 20 min, 800rpm ≙ 133 Hz b 20 min at 20 °C with maximal power input c 60 in at 80 °C d 30 min at 80 °C, maximal power input = 300 W The effective transfer of energy from the power socket into a product of interest has been proven for a number of exampl When different ball mills are compared with respect to their gross power ,
I’m interested to know when sizing a new ball mill, as to why recirculating load has no effect on the power calculation, although it will have effect on volumetric capacity naturally For instance a mill of 300tph with a 300% recirculating load would have 1200 tph going through effectively, but if
Stirred Mills have been proven to provide energy savings compared with traditional ball mills The finer the product required, the more efficient stirred mills will be than a ball mill The attrition grinding action, vertical arrangement, and the finer media size distribution contribute to make stirred mills more energy efficient grinding machin
