  • Ball Mill Motor Power Draw Sizing and Design Formula Ball Mill Motor Power Draw Sizing and Design Formula

    Oct 19, 2015 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 3.3 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

  • How to Calculate and Solve for Specific Power of Mill How to Calculate and Solve for Specific Power of Mill

    Jul 15, 2021 The formula for calculating the specific power of mill: E = w i (10 / √(P80) – 10 / √(F80)) Where: E = Specific Power of Mill w = Work Index of Ground Material P 80 = 80% Product Size F 80 = 80% Feed Size. Let’s solve an example; Find the specific power of mill when the work index of ground material is 10, the 80% product size is 14 and the 80% feed size is 8. This implies that;

  • Ball Mill Parameter Selection & Calculation - Power Ball Mill Parameter Selection & Calculation - Power

    Aug 30, 2019 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.

    The Critical Speed for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell's inside surface. This is the rotational speed where balls will not fall away from the mill's shell. Result #1: This mill would need to spin at RPM to be at 100% critical speed. Result #2: This mill's
