Cement Ball Mill
Cement ball mill is mainly used in the grinding of finished
products and raw materials in cement plants. It is also suitable
for industrial and mining enterprises such as metallurgy, chemical
industry and electric power to grind various ores and other
grindable materials.
advantages
- High stability, a number of new patents: CHAENG double belt belt
mill is the first company in China to solve the problem that the
mill can not run continuously due to the high temperature of the
belt bushing during unloading. And obtained the national utility
model patent, patent number: ZL201020285841.9. Many examples prove
that the CHAENG cement ball mill can operate stably for a long
time.
- The structure is novel and the production capacity is strong:
CHAENG cement mill adopts the latest and unique streamline design
in the world, which reduces the ventilation resistance, increases
the effective volume, makes the discharge easy, and improves the
output of the mill. The mill liner adopts a combined structure
design, and different liner structures are adopted at different
stages of the raw material grinding, which greatly improves the
milling efficiency. The drying capacity of the material can reach
10%~15%.
- The specific surface area of the finished product is
3300-3800cm2/g: the specific surface area of the cement produced by
the CHAENG cement plant is 3300-3800cm2/g. Compared with other
mills in the same industry, CHAENG cement mill has the advantages
of high product fineness, large specific surface area, fast
hydration reaction and fast strength development.

working principle
The material is uniformly inserted into the first chamber of the
ball mill by the feeding device through the hollow shaft of the
feeding material. The chamber has a step liner or a corrugated
liner, which is filled with steel balls of different
specifications, and the cylinder rotates to generate centrifugal
force to bring the steel ball to a certain height. Drops, causing
heavy impact and grinding on the material. After the material
reaches the rough grinding in the first bin, it enters the second
bin through the single-layer partition plate. The bin is embedded
with a flat liner with steel balls inside to further grind the
material. The powder is discharged through the discharge raft to
complete the grinding operation.
The main working part of the ball mill grinding material occurs on
the horizontal low-speed rotating cylinder. When the cylinder is
driven to rotate by the transmission device, the grinding body is
attached to the lining surface of the inner wall of the grinding
machine cylinder due to the inertia centrifugal force. After being
rotated together, after being brought to a certain height, it is
free to fall by gravity. At this time, the grinding body crushes
the material in the cylinder, and at the same time, the grinding
body has a rising and falling circular motion in the rotating mill,
and also generates Sliding and rolling, causing grinding between
the abrasive body, the lining and the material to be ground to make
the material fine. While the material is subjected to impact
crushing and grinding and grinding, the height difference of the
material surface of the material feeding end and the discharging
end makes the material flow slowly from the feeding end to the
discharging end to complete the grinding operation.
