Brief introduction of ball mills for sale :

The ball mills for sale 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.

Working principle of  ball mills for sale :
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.
