Ball Mill Motor Power Draw Sizing and Design

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 @ AllisChalmersThe 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 Ball Mill Design/Power CalculationTo match ball mill its motor size math required requirement calculated motor power applied the mill grind tonnage feed distribution following shows mill required calculated The represents section mill operation input required maintain condition theoretically:Matching Ball Mill Size to Horsepower ball mill motor power ball mill motor power 84 Total: (10) 61 Votes 58 Comments Currently, the Chinaware ball mill adopts mains supply, which is inclined to cause » Learn More motor power required to drive cement ball mill Grinding Home»Products»Ball Mill»motor power required to drive motor power requirements by ball mill – Grinding 12122016 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 Ball Mill Design/Power Calculation LinkedIn
