mills. SAG mills of over 40-foot diameter have been constructed. Like the ball mill, the AG/SAG mill will have a critical rotation speed above which grinding ceases. Mill motor types There are three common motor types that drive the grinding mills described above: – Gearless motors. These variable-speed motors range up to 30 MW and have the highest system efficiency.
the grinding media were calculated for evaluation of the grinding performance. There are models available for the calculation of the collision energy21–23). In this study, the collision energy E is de˚ned as E = 1 2 mv2, (2) where m is mass of grinding media, and v is relative velocity when the grinding media is collided with grinding media or wall.

SAG mills are essentially autogenous mills, but utilize grinding balls to aid in grinding like in a ball mill. A SAG mill is generally used as a primary or first stage grinding solution. 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.

Corrosion of grinding media can affect its longevity (internal structure) and performance. This is generally the case in mills where chemicals, water with an acidic pH level or the ore's characteristics create a corrosive environment. A way to combat this is higher chromium content in the grinding media.

For SAG mill commissioning/ongoing purposes we also manufacture low carbon, low hardness products with high impact resistance and toughness. Donhad has led the way in the development of "high carbon" products in the 52mm, 64mm, 78mm, and 125mm product categories which deliver improved wear performance over our competitors.
encountered following experimentation with the mill density, the effect of reducing mill speed should be assessed. The rate of abrasion grinding may be slower than the rate of impact breakage and the two can be brought into equilibrium by decreasing the impact force available through lowering the mill speed.
