Ball Mill - Edge-driving & Center-driving, High-performance Dynamic Pressure Bearings, Agma Standard Open Gear Design

Following are the Main Features of Ball Mill :-
1. The cylindrical mill adopts the driving type of edge-driving, center-driving, edge-driving with multi-point meshing, etc; driven by asynchronous motor+reducer+pinion and gear as well as synchronous motor+air clutch+pinion and gear.
2. Generally supported by static-dynamic pressure bearing on both ends. Fully closed selfaligning 120 degree osculation rocker bearing is used. Also single or double slipper static-dynamic bearings can be used. The bush is made by NC machine.
3. The large open gear is designed using AGMA standard, equipped with reliably sealed gear housing and grease automatic spraying lubrication system.
4. The shell is key part of a mill. Carry out finite element analysis on it with computer to ensure the reliable operation.
5. The shell is automatically welded, ultrasonic inspected, wholly annealed and machined by large special machine tools on one chucking. There are special seal on static-dynamic connection parts, such as feed and discharge hopper, turnnion, etc, to prevent oil and slurry leakage. The liner is of wear-resistance material made by our company, which has been specially heat-treated, with high hardness and long service life. Also other wear-resistance casting or rubber liners can be used.
6. There are slow speed drive for medium and large mill
7. The high and low pressure lubricating station is equipped for medium and large mill. The control and protection system is controlled by PLC.
