Ball Mill: Cement Mill

Ball Mill Application:


Cement ball mill is mainly used in grinding of finished products and raw materials in cement production. It's also applied to grind various ore and other grinding materials in metallurgical, chemical, electricity and other industrial and mining enterprises. It can be used to open-circuit grinding, as well as close-circuit grinding system together with separator. Cement mill has a strong adaptability to materials to production. It can be in operation continually and easy to control grinding fitness of production and so on. Ball mill of cement production is suitable to both drying production and wet production. What's more, the operation of grinding and drying can be done simultaneously.


The machine is composed by feeding part, discharging part, turning part and driving part (reducer, small driving gear, electric motor and electric control). The quill shaft adopts cast steel part and the liner is detachable. The turning gearwheel adopts casting hobbing process and the drum is equipped with wear-resistant liner, which has good wear-resistance. The machine is with stable and reliable working condition.
Moreover, according to different materials and discharging methods, there are dry ball mills and wet ball mills for choice.

Ball Mill Working Principle:


The ball mill is a horizontal rotating device transmitted by the outer gear. The materials are transferred to the grinding chamber through the quill shaft uniformly. There are ladder liner and ripple liner and different specifications of steel balls in the chamber. The centrifugal force caused by rotation of barrel brings the steel balls to a certain height and impact and grind the materials. The ground materials are discharged through the discharging board thus the grinding process is finished.
