Oct 12, 2017 · SAG mills are very important equipment of industrial mining. SAG mills are commonly used in mining fields. From mined coal, it separates out some precious metals. In the mining, some precious metals found are like gold, silver, nickel, and copper etc. . The internal machinery of ball mill grinds the raw material into the powder-like material .
The faster the mill speed, the greater the wear on the rods and liners. So, the general rule of thumb for rod mills is to operate no faster than the speed that will obtain the desired product size. The operation speed of rod mills is generally determined by the Peripheral Speed of the Inside of the mill. Generally, rod mills operate between 280 .

HRC™ - Mining Magazine award winner 2015! Mining Magazine has recognized 's HRC™3000 high-pressure grinding roll with its annual Minerals Processing award. The awards are given out in 11 categories and the winners are nominated by readers.
But it will effect on crushing rate. The mill speed can be recognized in two ways. As peripheral speed of the rollers i.e. the linear speed of a point at the mean diameter of roller. It is generally expressed in m/min. As speed of rotation of rollers, i.e. the no. of revolutions which they make in unit time.
The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and non-ferrous metals. The ball mill can grind various ores and other materials either wet or dry.
