Material being broken, then to smash the ball mill is critical equipment, it is widely used in building materials, chemicals, metallurgy, ceramics, electricity and mineral processing industry, mainly used for grinding various materials.

Uses: The machine used in cement, refractories, chemicals, nonferrous and ferrous metals such as factories, mines and industrial sectors are for grinding various ores and other grinding materials used.
The machine consists of feeding part, discharging Department, Rotary Department, Transmission Division (reducer, small transmission gear, motors, electrical control) and other major components. Hollow shaft with steel casting, lining Replaceable, slewing gear hobbing by casting process, the body inlaid cylinder liner wear, has good wear resistance. The machine running stable, reliable work.
Note: According to the ore material and scheduling methods, choose dry mill and wet lattice-type ball mill.

Use of the whereabouts of grinding media (such as steel balls, pebbles, etc.) as well as the impact of the role of the inner wall of grinding media and grinding and the abrasive material grinding and mixing. When the ball rotates, as grinding media and grinding friction between the inner wall. The grinding body according to the direction of rotation and then bring down. Ball mill This material was crushed on a continuous basis. According to the shape of the body can be divided into cylindrical grinding, taper grinding ball and tube (also known as tube mill) three.

Advantages are:

(1) can be used for dry grinding or wet grinding;
(2) good operating conditions, grinding machine in a confined within, there is no dust flying;
(3) reliable operation, grinding body cheap, and easy to replace;
(4) Intermittent operation can also be a continuous operation;
(5) smash explosive materials, the mill can be filled with inert gas instead of air.

Disadvantages are:

(1) volume of bulky;
(2) running a strong vibration and noise, must have a solid foundation;
(3) low efficiency, greater energy consumption;
(4) abrasive body and the body of the friction loss large, and will stain products. Crush the hard materials are widely used materials.
