CITIC Ball Mill Feature
(1) The cylindrical mill adopts the driving type 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 lclutch + pinion and gear.
(2) Generally supported by static-dynamic pressure bearing on both ends. Fuuly closed self-aligning 120º osculation rocker bearing isused. Also single or double slipper staic- 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 ahtomatic 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 special seal on static-dynamic connection parts , ch as feed and discharge hoper, trunnion, etc, to prevent oil and slurry leakage;
(6) The liner is of wear-resistance material mad by our company, wich has been specially heat-treated, with high hardness and long
service life. Also other wear-resistance casting or rubber liner can be used;
(7) There are slow speed drive for medium and large mill;
(8)The high and low pressure lubricating station is equipped for medium and large mill;
(9)The control and protection system is controlled by PLC.
