how to calculate sag mill ball charge

We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill.

The working principle of ball mill Meetyou Carbide

22/5/2019· The ball ratio is usually selected from 2:1 to 5:1. In some cases, a large ball-to-batch ratio is used. For example, a wet-milled titanium carbide-based carbide bar can be used for 6:1. Because the volume of the mixture is large at this time. It seems that using the ball to material volume ratio to indicate the amount of charge will be more

Mill Charge an overview ScienceDirect Topics

The ball load should be 40-58% of the total internal mill volume, and the material to be ground should fill only the voids between the balls (a maximum of twice the ball space) Viscosity, the order of filler addition, and the quantity of material should be chosen so as not to cause a viscosity increase above the specified range, since the milling efficiency drastically decreases at that point

AMIT 135: Lesson 7 Ball Mills & Circuits Mining Mill

Measurement of charge height is a convenient method to estimate charge volume. Generally : For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge
