In addition, the size distribution and grinding circuit The selection of an optimum top ball size for a large SAG mill is determined by several factors: wear rate, particle breakage effectiveness and liner damage. This example shows how 3D DEM can be used to provide quantitative input on each of these factors. In

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.

Estimating Ball Consumption

For an improved understanding, the wear rate constant is directly related to the grinding media consumption rate expressed in grams of steel per kWh drawn by the mill, using the simple expression: where dr represents the diameter of the new make-up balls periodically charged to the mill.

Ball Mill Lubrication Many mines or electric generating stations require raw minerals to be ground and pulverized for final processing. This process can be achieved through one of the different types of ball mills used – SAG Mill‚ Ball Mill‚ Rod Mill and Double Ended Ball Mill included.

Further tests were done, using samples from a platinum mine, namely the feed to a secondary mill (ball-mill) and rounded pebbles from a primary AG mill. Grinding capacity was maintained over the range 0-30% pebbles, by volume, with savings in energy and ball consumption increasing progressively.

2020/9/7Depending on the mill size the SAG mills draws between 2 MW and 17 MW. The product from the SAG mill is further reduced in size using pebble crushers and ball mills. Hence, typical gold or copper ore requires between 2.0 and 7.5 kWh per ton of energy to reduce the particle size.

Ball mill is a fine grinder. A horizontal or vertical rotating cylinder which is filled partially with the balls of ceramics, small rocks and balls made from stainless steel. The ball charge of a SAG mill is about 29% to 30%. By friction and influence of tumbling balls inside

surface of the mill flange. Typically, the synchronous motors used in SAG mills have a power higher than 10 MW. Even ball mills have a power larger than 10 MW. For this reason, they have an important impact in energy consumption and in the operation of the
