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.

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.
