A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of ahallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.

Ball Mill
The ball mill is one of the most widely used super fine grinding machine in the industry and it is the key grinding equipment after materials have been crushed.
Rod Mill
Hongxing rod grinder is especially suitable for crushing river gravel to make sand. It's a kind of effective and energy saving rod grinding machine.
Shaking Table
In the metallurgical industry, shaker table is mineral processing equipment used for sorting fine material.
Agitation Tank
Stirring tank is suitable for mixing before flotation, for various metal and ores to adequately mix pharmaceutical and pulp, and it can also be used for mixing other non-metallic minerals.
The disadvantagesof ball millsinclude their considerable metal consumption and deterioration grinding media, as well as a lot of noise. Most of the energy useless lost duringball mill operation, leading to low it efficiency. But even a significant specific energy consumption for grinding material compensates beneficial effect by usingmill.
Ball mills give acontrolled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel.
Moreover, according to different materials and discharging methods, there are dry ball mills and wet ball mills for choice. Ball Mill Application Ball mills arethe key equipment for grinding after the crushing process, which is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer,ferrous metal, nonferrous metal andglass ceramicsand can be …
