Product Description
usage
Ball mill is the key equipment to crush the material after it is broken.
Ball mill is one of the high fine grinding machines widely used in industrial production.
There are many kinds, such as horizontal ball mill, ball mill bearing bush, energy saving ball mill, overflow type ball mill, ceramic ball mill, grid ball mill, etc.
Ball mill is suitable for grinding all kinds of ore and other materials, is widely used in mineral processing, building materials and chemical industries, can be divided into dry and wet grinding methods.It can be divided into two types, grid type and overflow type, according to different discharging modes.

Our largest mills has been delivered to SINO Site to date are Ø12.2m x 11m 28MW Gearless Drive AG Mills and Ø7.9m x 13.6m 2x8 MW Twin Pinion Drive Ball Mills. These mills are scheduled of start up on 2012.
Our market share in China exceeds 80% with the largest mills supplied to date being a Ø7.9m x 13.6m 2x8.5MW Ball Mill and a Ø11m x 5.4m 2x8.5MW SAG Mill , being the largest in China.CITIC HMC Company is the key large enterprise for the design and manufacture equipments in China. The manufacture of grinding equipment begins from 1960s. Since 1980s,our company has cooperated with many famous foreign grinding manufactures on technology introduction ,cooperating manufacture and development. We have in particular long experience in mill testing, study, design, made and field operation, and made advancement and innovation on foreign technologies. Now we have established our own grinding laboratory, formed various type mills to series, totally produced over 1000 sets, and exported to Australia, Russia, Pakistan, Zambia, Indonesia, Vietnam, Canada etc. we have produced the overflow ball mill with the largest size Φ5.5×8.5m, Φ8.5×4.0m semi-autogenous mill, Φ5×15.5m tube cement mill Φ5m vertical cement raw mill, etc.
Our company possesses the national first-rate study and group on mill, perfect experiment and testing measures, and superior manufacturing equipment and technology on large- scale mills, we have formed complete supplying system for mill experiment, study design, manufacture, testing and service.
Ball Mill Application:
A ball mill grinds ores and other materials to a typical product size of 35 mesh or finer.
The feed to a ball mill is prepared by...
· Single or multistage crushing and screening
· Crushing, screening, and/or rod milling
· Primary crushing and autogenous/semiautogenous grinding
Ball Mill Normal feed sizes:
· 80% passing 1/4" (6 mm or finer) for hard ores
· 80% passing 1" (25 mm or finer) for softer ores
(Larger feed sizes can be tolerated depending
Grate or Diaphragm Discharge Ball Mill
In the discharge end of this mill, a slotted full diameter or partial diameter grate with discharge lifter assembly conveys the material to the discharge trunnion opening. The grate serves to retain balls, tramp, and coarse material. A gradient created between the feed opening and the discharge slots eases the flow of material.
Trunnion Overflow Discharge Ball mill
A trunnion overflow mill has an open discharge end. Material flows through the trunnion as a result of the pulp gradient between the feed and discharge openings. A reverse helix in the discharge trunnion liner retains balls in the mill.
CITIC Ball Mill Feature
♦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.
♦Generally supported by static-dynamic pressure bearing on both ends. Fuuly closed self-aligning 120º osculation rocker bearing is used. Also single or double slipper staic- dynamic bearings can be used. The bush is made by NC machine.
♦ The large open gear is designed using AGMA standard, Equipped with reliably sealed gear housing and grease ahtomatic spraying lubrication system.
The shell is key part of a mill. Carry out finite element analysis on it with computer to ensure the reliable operation;
♦ 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;
♦ 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;
♦ There are slow speed drive for medium and large mill;
♦The high and low pressure lubricating station is equipped for medium and large mill;
♦The control and protection system is controlled by PLC.
