Grid ball mill is widely used in smashing all kinds of ores and other materials, ore dressing and national economic departments like building and chemical industries etc. The size of ore shall not exceed 65mm and the best feed size is under 6mm.
An investigation was conducted to determine the effect of the ball diameter sizes on milling operation. A laboratory size ball mill was used with ball media of sizes 10 mm, 20 mm and 30 mm respectively. Quartz was the material used to perform the experiment and was arranged into 3 mono-sizes namely -8 mm 5.6 mm, -4 mm 2.8 mm and-2 mm 1.4 mm ...
Comparative batch tests on ball mill feed with the current and an alternative ball charge may show increased grinding rate through the size of interest, but lower rates at coarser particle sizes. Locked cycle tests are then needed to determine whether a net increase in grinding efficiency will result.

About the BallRod Mill Ball mills and rod mills are essential mining equipment for further size reduction of ore after the crushing stage. They are applicable to the comminution of dry or wet ores and other grindable materials in ferrous and non-ferrous metal processing plants, cement plants, refractory plants, fertilizer plants, and smelters.

these purposes. Choose a closing screen for the ball mill test that is one standard square root of 2 series mesh size coarser than the plant ball mill circuit P80. If choos-ing between two standard mesh sizes, choose the finer one.
DOVE Ball mills, also known as Grinding mill, Mining mill, Pebble mill, Ball amp Pebble mill, is an important machinery in the mining and various other industries, which would require grinding different material. They are highly efficient Grinding mill machines, designed for grinding applications, where fine material is required.
The cyclone battery underflow reports to the ball mill to maintain a recirculating load to have a better control on the flotation feed size, while the cyclone overflow reports to flotation. Both mills are 6.7m in diameter and 7.5m. long. Grinding circuit feed and product is 80 passing sizes of 120,000 m and 75 m, respectively.
