Ball Mill Design/Power Calculation
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 open/closed The following equation is used to determine the power that wet grinding overflow ball mills should draw For mills larger than 33 meters (10 feet) diameter inside liners, the top size of the balls used affects the power drawn by the mill This is called the ball size factor S Rod and Ball Mills by CA Rowland and DM Kjos @ AllisChalmersBall Mill Motor Power Draw Sizing and Design FormulaA 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 The drive system can either consist of a central drive (central gear unit: helical gear unit or planetary gear unit) or Industrial gear unit drive solution for ball mills SEW

Power required to drive a ball mill with a particular ball load is proportional to (where, D = diameter of ball mill)The ball mill motor power requirement calculated above as 1400 hp is the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution the following shows how the size or select the matching mill required to draw this power is Ball Mill Motor Power Wiring DiagramMotor Power Requirements By Ball MillThe 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 Ball Mill Design/Power Calculation
Ball Mill Motor Power Draw Sizing and Design Formula
The following equation is used to determine the power that wet grinding overflow ball mills should draw For mills larger than 33 meters (10 feet) diameter inside liners, the top size of the balls used affects the power drawn by the mill This is called the ball size factor S Rod and Ball Mills by CA Rowland and DM Kjos @ AllisChalmersA 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 The drive system can either consist of a central drive (central gear unit: helical gear unit or planetary gear unit) or Industrial gear unit drive solution for ball mills SEW Motor power to drive ball mill figure 9 shows the milldrill with the existing xaxis on the left end of the tablehe yaxis has now been fitted with the rebored driven timing pulley instead of the handwheeligures 10 and 11 show closeups of the yaxis timing pulley before mounting the motor Selecting Inching Drives For Mill And Kiln Applications Motor or the free end of the mill pinion data Motor Power Requirements By Ball Mill

Ball mill Wikipedia
A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell A ball mill consists of a hollow cylindrical shell rotating about its axis The axis of the 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 The drive system can either consist of a central drive (central gear unit: helical gear unit or planetary gear unit) or Industrial gear unit drive solution for ball mills SEW 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 The drive system can either consist of a central drive (central gear unit: helical gear unit or planetary gear unit) or Industrial gear unit drive solution for ball mills SEW
