Ball Mill is widely used in cement, silicateproduct, new building materials, fire-proof material, chemical fertilizer, black and non-ferrous metal processing, such as glass-ceramics industry production of all kinds of ores and other materials may be grinding of dry or wet grinding
Working principle:
The ball mill is horizontal cylinder rotating device, outside edge gear transmission, two storehouse, grate ball mill,the material enters spirally and evenly the first warehouse of the milling along the input material hollow axle by input matearial device,in this warehouse,these is a ladder scaleboard or ripple scoleboard,and different specification steel balls are installed on the scaleboard,when the barrel body rotates and then products centrifugal force, at this time,the steel ball is carrled to some height and falls to grind and strike the materials,after being grinded coarsely in the first warehouse,the material then enters into the second arehouse for regrinding with the steel ball and scaleboard,in the end,the power is discharged by output naterial board and the end products are completed.
Structure of Ball mill:
The machine is composed of 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.
