Ball Mill are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced. Various classifiers, such as screens, spiral classifiers, cyclones and air classifiers are used for classifying the discharge from ball mills. Ball mill is an efficient tool for grinding many materials into fine powder. The ball mill is used to grind many kinds of mine and other materials, or to select the mine. It is widely used in building material, chemical industry, etc. There are two ways of grinding: the dry process and the wet process. It can be divided into tabular type and flowing type according to different forms of discharging material.

The ore was first crushed by an jaw crusher, after crushing through the hoist, to the mill even into the ball mill, the ore is crushed and ground by a ball mill. The ore grinded by the ball mill frits into the spiral classifier. After the cleaning and grading of the mineral mixture into the magnetic separator, magnetic particles by separation machine of the initial separation are gone into the flotation machine.After the desired minerals are separated, because it contains a lot of water, subjecting to the initial concentration of the concentrator, And then dried by the dryer, you can get dry minerals.
