The mainbody of the ball mill is a low-speed rotary cylinder mounted on two large bearings horizontally. The ball mill's rotary part is driven at reducing speed by motor through speed reducer and gearweheel or by low-speed synchronous motor through gearwheel. Inside the cylinder feed proper grinding medium-steel balls. The medium will be lifted to certain height under the action of centrifugal force and friction and drop or fall. The material to grind is fed to the cylinder in succession and crushed by grinding medium, then discharged through overflow and continual feeding force, and enter the next procedure.

Features of Ball Mill

1) The ball mill is an efficient tool for grinding many materials into fine powder.

2) Ball mill is widely used in building material, and chemical industry.

3) There are two ways of grinding: the dry way and the wet way.

4) Ball mill can be divided into tabular type and flowing type according to differentexpelling mine

5) To use the ball mill, the material to be ground is loaded into the neoprene barrel that contains grinding media.

6) As the barrel rotates, the material is crushed between the individual pieces of grinding media that mix and crush the product into fine powder over a period of several hours.

7) Ultimate particle size depends entirely on how hard the material you're grinding is, and the time how long the ball mill runs.

Structures of Ball Mill

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.
