Please remember that this calculator works out the ''minimum'' battery bank size for a given power consumption. When using an inverter, the current draw on the battery side can be extremely high, so you may need a battery bank that is larger than the minimum. For example, 1200W drawn at 240V is only 5A, whereas at 12V this current increases to 100A. We .
The work performed included analysis of operating performance data from 49 mills and included extensive determinations of the Bond Abrasion Index for different ore types.

Milling Stepover Distance Calculator. In many milling operations, the cutting tool must step over and make several adjacent cuts to complete machining a feature. As a result, a small cusp of material, called a scallop, will remain between these cuts on any surrounding walls or on the machined surface if a ball end mill is used.
The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ''chunk size'', product size as P80 and maximum and finally the type of circuit .
