مصنع لتجهيز البوكسيت/ball mill for aggregate
Ballmills are used widely for secondary grinding. Loveday (2010) reported on laboratory tests in which small pebbles (725 mm) were used in various proportions with balls. The optimum proportion of pebbles, by volume, was found to be about 25%. Substantial savings in power and ball consumption were achieved, with no loss in grinding capacity.
Based on his work, this formula can be derived for ball diameter sizing and selection: Dm <= 6 (log dk) * d^ where D m = the diameter of the singlesized balls in = the diameter of the largest chunks of ore in the mill feed in mm.

The water can wash away the fine particles in time to avoid overgrinding. The wet ball mill has a low noise, and low environmental pollution. The wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%10% lower than that of a dry ball mill. The grinding particle size is fine and uniform.
Smelting and refining. Ball mills are employed in the comminution stage as grinding machines ( size reduction ). The purpose of grinders in the mining industry is to reduce the feed material size in order to liberate the minerals from the barren rock. Ball mills are the most common grinding machine employed in the mining industry.

Crushing and grinding are the two primary comminution processes. Crushing is a dry process in crushing arejaw crushers, gyratory crushers and cone crushers. While grinding is generally performed wet in rod mills and ball mills. Our grinding balls have always been active in crushers, ball mill, sag mill and rod mill for the field of comminution.
To produce high quality recycled concrete aggregate by effectively removing the adhered mortar of (5 ~ 40 mm) size grains, the use of ball mill or tube mill is cheaper relative to other improvement methods. The working principle of ball mill is presented in Fig. 4 b [92], [6]. This device is provided with several partitions which contain steel ...
