Ball mill is a key equipment for regrinding, it is widely used for the cement, the silicate product, new type building material, fire-proof material, chemical fertilizer, black and non-ferrous metal, glass, ceramics and etc.Ultimate particle size depends entirely on how hard the material you”re grinding is, and the time how long the Ball Mill runs. Ball mill can be divided into lattice type and overflow type according to different beneficiation methods, and this machine is two lattice-type ball mill. The materials from the feeding fittings enter evenly to the first bin of the milling machine via the feeding hollow axis when it works.

Ball mill can grind ore or other materials that can be grinded either by wet process or by dry process.

Working principle of ball mill:

1. This ball mill is horizontal type and tubular running device, has two warehouses.

2. This machine is grid type and its outside runs along gear.

3. The material enters spirally and evenly the first warehouse of the milling machine along the input material hollow axis by input material device.There is a ladder-like or ripple-like scaleboard in the first bin, and different specification steel balls are installed in the bin. When the cylinder rotates and produces centrifugal force, the force carries steel balls into a certain height and then makes them fall to strike and grind the materials.

Materials after crushed in thefirst bin shall enter bin across single-layer diaphragm into the second, which is provided with flat lining with steel balls, to go through further grinding. Powder shall be discharged from discharging grating, ending the milling process.After coarse grinding in the first bin, the material then enters into the second bin via a single layer partition board. There is a scaleboard and steel boards in the second bin, so the materials are further ground. In the end, the powder is discharged by output material board.
