Add Steel Ball Correctly to Improve Ball Mill Grinding

When the steel balls in the ball mill barrel are too small, the crushing capacity of each steel ball is maximized, but the overall crushing capacity is limited, thus affecting the grinding efficiency of ball mill. Therefore, it is very important to keep the steel ball amount reasonable and balanced when using a ball mill.

Mill (grinding) - Wikipedia

SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.

There are sources for small milling balls for milling pigments and small batches in small ball mills i.e. bench-top mills. Balls wear down and smaller (worn) balls can be found on the market or discarded around old mill sites. The control variables used in milling are time, rotational speed, and number of balls.

It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the
