Ball mill
Ball mill process
Material is fed by the feeding device into the first chamber where material is impacted and crushed to a certain size by the grinding medium with average big diameter ball and then into the second chamber through the welt.
In it there are average small balls to further grind the material. After grinding, the material passing through the discharging grate plate and discharged out from the bottom of the discharging device, then selected by the matched separator, coarse powder will be ground again and qualified powder will become final product. Ball mill is composed of feeding device, feed and discharging sliding shoe bearing, transmission part, discharging device and sliding shoe bearing lubrication and central transmission device, for example, main reducer and lubrication device,main motor,slow drive device,etc.

Features
Advanced lathe, precised process technology
LCDRI have few 5.3x18m heavy digital display horizontal lathe, can process high-precision cylinder to guarantee the no-circular rate and concentricity of slip ring processing to minimize the error. Cylinder is key-module for mill,carries on the finite element analysis with computer to ensure its reliability.
Various transmission way, compact structure
Cylindrical mill adopts edge transmission, center drive, multipoint meshing transmission, etc. Type of drive have asynchronous motor, reducer, pinion, gear and synchronous motor, air clutch device, pinion, gear. Large and medium mill is equipped with slow drive device and high and low pressure lubrication station.
Advanced supporting way
Generally adopts two ends static and dynamic pressure bearing supporting method, using completely closed 1200line contact “joystick”type bearing, which can also use single slipper, double slipper static and dynamic pressure way of support or total static pressure support.
American design criteria
Large open gear adopts U.S.AGMA standard design and equipped with a reliable sealing of the gear cover and glycerol spray lubrication device, control and protection system adopts PLC control.
