LG A mill power equation for SAG mills. Minerals and Metallurgical Processing. Feb 1990 pp5762. Gross power No load power Net power drawn by the charge () The net power is calculated from Net power e! c./ Watts () In equation, D is the diameter inside the mill liners and Le is the effective length of the mill including the ...
A direct measurement of the ball level in the mill, more accurate than power readings, as well as a control of it, is therefore highly important. Load angle as an indicator of milling efficiency? Toe and shoulder angles of the charge are always used for liner design .
The Functional Performance Equation for ball milling circuits allows us to isolate the circuit classification system efficiency (CSE) from the mill''s grinding performance.

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1– times the shell diameter (Figure ).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
2) Ball milling – a ball mill with a diameter of meters, inside new liners, grinding wet in open circuit. When the grinding conditions differ from these specified conditions, efficiency factors (Rowland and Kjos, 1978) have to be used in conjunction with equation 1.
Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics. Typical examples are the various ores, minerals, limestone, etc. The applications of ball mills are ubiquitous in mineral
The "effective mill power" (EMP) can then be defined relative to the total mill power (TMP). EMP is the percentage of total mill power draw delivered to the "coarse" ore and is defined as EMP = TMP x CSEff (1) The ball mill circuit functional performance equation. A practical measure of .
