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 % 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 tonnage of feed from one size distribution The followingBall Mill Design/Power Calculation LinkedInThe 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 1 Calculation of ball mill capacity The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), the Ball Mill Parameter Selection Calculation According to the proposed method the calculation of power consumption was performed for the tubular ball mill Ø4×13,5 m They also recorded the The power consumption calculation of a ball
