 ball mill    The  ball mill is widely used to grind various medium-hard ores and other materials in mining, building materials, chemical industries, etc. The ball millcan be divided into dry type and wet type according to the milling method; grid type and overflow type or center-discharge and side-discharge type according to the ways of discharge; bearing-mill and bearing pad mill according to the different methods of supporting; rim drive and center drive according to the different ways of transmission. The large mill with diameter above 3 meters is especially configured with jack-up devices for easy maintenance; the dynamical pressure bearing and the static pressure bearing can operate stably. Slow rotation is convenient for overhaul and start; the oil sprayer   lubrication device can make big and small gears reliable. The main motor of large mill is high pressure asynchronous motor or synchronous motor, which should be notified in the orders.

ball mill   Working principle    The ball mill is driven by brim gearwheel. There are two chambers and grid. Material goes into the first chamber through the feeding inlet. Inside the first chamber, there are stage liners and ripple liners as well as steel balls. The shell rotates so as to generate electricity, and this force brings ball to a certain height and then balls drop down by gravity, the impact is the grinding force to the material. After the primary grinding, materials go into the second chamber through segregate screen. In the second chamber, there are flat liners and steel ball, after the secondary grinding, material is discharged from the discharging. Then the whole grinding process end.

Structure

The machine is composed by feeding part, discharging part, rotation 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 rotation big gearwheel is made by cast hobbling processing 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.
