In the mineral processing industry, mine ball mill widely used in metal and nonmetal mines, building materials and other departments to smash all kinds of ores and rocks. Diameter of tube ball mill is 900 ~ 2100mm, the main bearing with spherical bearing, cylinder diameter more than 2700mm using completely closed self aligning type, 120 ° rocker bearing, high lead low hot wine low hardness Babbitt, the buried water cooling pipe, bearing with static structure the high voltage oil station, joint lubrication. Main bearing sealing with the outside of the piston ring type, with the aid of a rubber strip and grease to achieve a good seal, ball mill using new technology of large gear radial sealing and automatic spray lubrication in structure.
Ball mill with slow drive device can make the host to get 0.15r/min speed, turning, grinding mill for maintenance or loose load, at the same time grinding mill with lifting device for maintenance lifting rotary part.
The main mine ball mill is simplified a horizontally arranged in two large bearing on the low speed rotation. Ball mill by the motor through reducer and the surrounding large gear transmission, or from low speed synchronous motor directly through the surrounding big drive gear, driven rotating part of rotary. The inside of the cylinder is provided with a grinding medium ball properly. The grinding mill medium in the centrifugal force and friction under, be lifted to a certain height, the drop or drain fall down state. Be ground material from the feeding port continuously into the simplified internal, by the movement of the grinding medium crushing, and through the overflow and continuous feeding power products will be discharged out of the machine, for the next period of process.
