The starting point for ball mill media and solids charging generally starts as follows: 50% media charge; Assuming 26% void space between spherical balls (nonspherical, irregularly shaped and mixedsize media This is a 2nd Method for estimation or measuring the steel charge volume inside a mill If dealing with a full SAG/AG mill, this will give you the rock load% If you can count liners, you’ll have your Estimate Mill Steel OR Rock Charge Volume 911

Charge behaviour and power consumption in ball mills:

Abstract Discrete element method (DEM) modelling has been used to systematically study the effects of changes in mill operating parameters and particle The approximate horsepower HP of a mill can be calculated from the following equation: HP = (W) (C) (Sin a) (2π) (N)/ 33000 where: W = weight of charge C = distance of centre of gravity or charge Ball Mill Design/Power Calculation 911 Metallurgist
