Jun 14, 2018 Many early mines used stamp mills, but many operations today find that ball mills are functional for smaller operations and perform well with the modern equipment we have available now such as combustion engines. The Function of a Ball Mill . To perform its functions, the ball mill operates on the principle of impact and attrition.
Then I will introduce operation principle of wet long cylinder ball mill, make the wet long cylinder ball mill of Xinhai Mining Group as an example. Just like the picture, the aspect ratio is much larger than the conventional ball mill, the inside of the cylinder is divided into two to four different lengths and functional positions.
Cone ball mill is a common ball mill of mining processing. This ball mill changes former structure of ball mill, and it enables the integration of body and chassis. About the installation, it can only use once to plate on the plane. Besides, it uses spindle double row spherical roller bearings to replace the conventional sliding bearings.
The disadvantages of ball mills include their considerable metal consumption and deterioration grinding media, as well as a lot of noise. Most of the energy useless lost during ball mill operation, leading to low it efficiency. But even a significant specific energy consumption for grinding material compensates beneficial effect by using mill.

Dec 22, 2020 Gold plant ball mill circuit operation Very often in SAG circuits, the ball mill circuit is neglected. In many operations where economics dictate that throughput is worth economically than the required sacrifice in grind, the focus shifts to throughput so much that the available ball mill power is not used to the fullest extent.
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.
