Optimizing Primary Grinding Capacity. The relation of fineness of grind to the degree of liberation of the valuable minerals from the gangue is certainly a factor to be considered in optimizing the primary grind. This largely determines the grind-recovery curve and the point of maximum recovery, which is normally at a very fine grind.
Key benefits. Highest possible discharge capacity through elimination of pulp lifters. Maximized slurry transport and impact energy with lowest possible slurry pool level. …
Milling is among the most energy-consuming technological stages of copper ore processing. It is performed in mills, which are machines of high rotational masses. The start of a mill filled to capacity requires appropriate solutions that mitigate the overloading. One method for increasing the energy efficiency of ball mills is to optimize their drive …
There are numerous benefits associated with using HPGR technology within aggregate and mining grinding applications. Where HPGR technology has replaced traditional methods of crushing and grinding (e.g. SAG or ball mills), it has: Provided excellent throughput capacity and energy efficiency. Decreased energy consumption by up to 40%.
The length and diameter of a SAG mill are determined principally by the desired throughput capacity and the grindability of the ore. For conventional ball mill grinding, grindability is usually expressed in terms of the Bond Work Index, which is determined in laboratory tests and expresses numerically the power required to reduce …

Hard ore Work Index 16 = 100,000/65,000 = 1.54 kwh/t. For the purposes of this example, we will hypothesize that the the crushing index of the hard ore with the increased energy input of 1.54 kw/t reduces the ball mill feed size to 6,500 micrometers. As a result, the mill output will increase with this reduced size to approximately 77,000 tons ...
The coarse copper's ore size reduces due to the interactions between copper ore and steel balls during the ball mill's rotation.
