# Motor Calculation Of Ball Mill Design ﻿ A Total Apparent Volumetric Charge Filling – including balls and excess slurry on top of the ball charge plus the interstitial voids in between the balls – expressed as a percentage of the net internal mill volume inside liners B Overflow Discharge Mills operating at low ball fillings – slurry may accumulate on top of the ball charge causing the Total Charge Filling Level to Get a Quote Send Message motor calculation of ball mill design

Ball Mill Design Power Calculation 2019620 A motor with around 1400 Horse Power is calculated needed for the designed task Now we much select a Ball Mill that will draw this power 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 Dec 12 2016 · Example Calculation A motor with around 1400 Horse Power is calculated needed for the designed task Now we much select a Ball Mill that will draw this power Ball Mill MotorPower Sizing Calculation

Ball Mill MotorPower Sizing Calculation A reasonable default value for this angle is 32° but may be easily “tuned” to specific applications against any available actual power data The effect of change of feed size or of return of a classified fraction is obtained by direct experiment This is a more timeconsuming method Design Method of Ball Mill by Sumitomo Chemical Co

Design Method of Ball Mill by Discrete Element Method The physical constants used in these calculations are given in Table 1 In a discrete element method simulation of the inside of a ball mill the coefficient of friction of the balls is the most important factor and it has been CALCULATION OF THE POWER DRAW OF DRY

Calculation of the power draw of dry multicompartment ball mills 223 Where gross power is the power input to the motor noload power is the power input to the motor when the mill is empty chargemotion power is the power associated with the movement of the charge and k x chargemotion power is the total power input to the charge Ball Mill Drives Mineral Processing Metallurgy

Ball Mill Drives One important advantage of the synchronous motor is the possible correcting of power factor within your operation through its use When using a synchronous motor we recommend having 200 starting torque 120 to 130 pullin torque and 225 pullout torque These assume no greater than a 10 voltage drop at the motor terminals Calculate and Select Ball Mill Ball Size for Optimum Grinding

Calculate and Select Ball Mill Ball Size for Optimum Grinding Based on his work this formula can be derived for ball diameter sizing and selection Dm 6 log dk d05 where D m the diameter of the singlesized balls in mmd the diameter of the largest chunks of ore in the mill feed in mm GROSS POWER CALCULATOR SMC Testing
