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.

FM 306: SIZE REDUCTION AND SIEVING - IIT Bombay

Ball Mill: The equipment to be used for size reduction is ball mill. The ball mill is kind of grinder used for intermediate or fine grinding. Ball mill is a metal cylinder which rotates about its horizontal axis. The coarse material charged along with the metal balls breaks to fine powder by impact of metal balls. 1

Energy Use of Fine Grinding in Mineral Processing | SpringerLink

Dec 18, 2013 · While Millpebs can give significantly lower energy use when grinding to finer sizes, they also can lead to high fines production and high media use. Millpebs were tested for fine grinding at the Brunswick concentrator. The regrind ball mills at the concentrator used 25-mm slugs to produce a P80 of 28 μm.

The operating principle of the ball mill

Energy consumption for ball mills is a function of many factors: the physical properties of the ground material — its specific gravity and hardness; the degree of drum filling by grinding balls; the number of drum rotations, etc. Ball mills have low efficiency — no more than 15%. Energy is mainly consumed on the wear of grinding balls and
