Ball mill is one of the crushing equipment in mining machinery. With the continuous development of domestic economy, ball mill has become an indispensable equipment in the industrial developement.It can be used to crush less than 320 million mpa hard stones and materials.in the highway, coal, building materials, metallurgy and other industial departments.

The ball mill is made up by feeder, charging port, barrel, discharging port, bearing, transmission device, reducer, coupler and so on. The barrel formed by the melt steel plate, one end of the barrel joint with the charging port hollow shaft by the bolt, and the other one joint with the discharging port hollow shaft. The ball mill barrel is horizontally supported by two main bearings. Inner of the the hollow shaft there is changeable lining as the channel of raw material charging and end product discharging. There are high manganese steel lining plat and white iron lining plate in the inner wall of the ball mill barrel, and there are a mount of grinding media and grinding raw material in the barrel.

When the rotating around the axis, for the centrifugal force the mass point of the mixture in the barrel will rise to a certain height, then fall down on parabolic trajectory. There are two reasons for the raw materials grinding to fine powder in the ball mill, one is the impact force of grinding media, one is the collision among the raw material and the grinding media and the ball mill barrel inner wall, finally, the fine end powder product discharged from the other end of barrel by the water power or wind power and the grid lining board.

The main products of Fote Machinery are crushers, mobile crusher plant, grinding mills, other equipments for stone production line, sand making line and grinding mill plant, as well as building construction equipments.
