Centrally-driven ball mill

Centrally-driven ball mill

It is mainly used in industries such as cement, coal separation, electricity generation, building materials and compound fertilizer.

Advantages:Inquiry > >

  1.Center transmission ball mill absorbs international experience, and adopts center transmission form. It has coherent structure, small floor area, good reliability and simple structure, which is easy to install, operate, and maintain, also has high efficiency and long lifespan.
  2.It adopts center rotation, has no pinion and gear, motor and reduction box. The rotating part and barrel are at the same axis. The barrel is supported by double spherical roller bearing. It is rolling friction between center hollow shaft and main shaft. The friction is small, and it can save consumption, work stably and operate stably.
  3.It adopts fluid coupling, the rotating efficiency is high, and it does not need gear and pinion, which reduces the quality and cost. The power of motor is low, compared with the same model of ball mills, and it can reduce 10.7%-40.5%.
  4.The bearings of center transmission ball mills is big type, and carrying capacity is higher than load. The lifespan of center transmission ball mill is higher than traditional mills.
