Nov 26, 2019· The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill’s

Mar 20, 2020· Ball mill: When the particle size of the product is less than 0.5mm, the grinding effect of the ball mill is greater than that of a rod mill of the same specification. SAG mill: The SAG mill has a wide range of feeding particle sizes and can process larger minerals, but at the same time, its output particle size is relatively larger.
Jun 19, 2015· A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell’s inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula. The mill speed is typically defined as the percent of the
The SAG Mill is a machine added by Ender IO.It uses Micro Infinity (µI) to grind (or mill) items into their crushed variants, like Ores into Dusts.The SAG Mill has four output slots; recipes can have 1-4 different outputs, with different chances of obtaining those outputs. Uniquely, the SAG Mill can use Grinding Balls made from various materials to increase energy efficiency
The SAG mill specific energy consumption (E SAG) is calculated using the 1979 Barratt equation and the ball mill specific energy consumption (E bm) This model includes a phantom cyclone effect in the equations due to the ball mill being calculated by difference and not being calculated by the normal Bond equation. The resultant operating work
