Special features of ultrafine mill, vertical cement mill
1. High efficiency, 0.5-12 t/h
2. Long lifecycle of spare parts. The ring and roller are forged by
special material with high utilization.
3. High safety and reliability. As no rolling bearings or screws in
grinding cavity, there are no problems caused by bolts shedding or
rapid wear of bearings and seal components.
4. High fineness and flexible adjustment. 325-2500 meshes (47-5
microns) adjusted.
5. Environment-friendly. The application of pulse bag filter and
muffler greatly alleviates dust pollution and noise.
6. Advanced intelligent speed control device. Convenient adjusting,
more uniform particle size.
Working principle of ultrafine mill, vertical cement mill
After crushed by hammer crusher, the large materials become small
ones and are sent to storage hopper by elevator, and then evenly
sent to the upper distribution plate of the turn plate by vibrating
feeder and sloping feeding pipe.
When the grinding mill is at work, the main bearing and each dial
are driven by electromotor through reducer, and all the grinding
rollers are rolling in the ring channels driving by dial through
plunger. The materials are driven to the edge of the turn plate by
the centrifugal force and fall down into the grinding chambers.
The high-pressure air blower constantly inhales air, the airflow
with crushed materials are brought to the classifier whose
high-speed impeller will screen the airflow: the unqualified
particle size will fall and return to the mill for being reground
while the qualified particle size mixed with air will go into the
cyclone powder collector. Most of the qualified powders will fall
and exit from the discharging valve at the bottom; a small
proportion of the fine powders, with airflow, moves to the dust
cleaner. The materials from the above two lots are sent by the
conveyor to get finished powders packed. In addition, filtered
clean air will be emitted from muffler in the end.
Cement Vertical Mill
Features
1. Technique and technology is mature and stable
CITICIC’s cement vertical roller mill in the production of cement
specific surface area up to 3800 cm²/ g with stable and reliable
quality, it already have been the ability completely to replace
tube mill.
2. Reducing the power consumption of cement clinker preparation
effectively
According to the display of pulverized coal measured data, it can
be saving electricity above 30% use of vertical roller mill
production per ton cement clinker than traditional tube mill, and
the power saving effect is very remarkable.
3. Stable, high-efficiency and environmental protection
There is a low vibration and noise in overall system, and equipment
with whole sealing, system working under negative pressure with no
dust overflow, clean environment. Therefore, cement vertical roller
mill meets the national environmental protection requirements. With
working mechanism changing, cement vertical roller mill can be
reduced friction and improved service life.

Vertical Raw Mill-Raw Material Vertical Mill
Features of Raw Vertical Mill:
Our vertical raw mill has various advantages when compared with
other similar machines. Detailed information will be given in the
following.
1. High grinding efficiency: advanced grinding principles makes it
possible to save as much as 20~30% power consumption when compared
with the ball mill. With the increasing of moisture content, it can
save more and more electricity.
2. Strong drying capacity: it can make use of the hot waste gases
from the kiln to do drying, and it is capable of drying and
grinding raw materials with moisture content as much as 15%.
3. Small in size, and simple process flow: it has integrated
crushing, drying, grinding, separating and conveying into one body.
4. Low noises and little dust: there is no direct contact between
the grinding rollers and grinding disc. So metallic impact is
avoided and its noises is 20~25 decibels lower when compared with
ball mill. Totally closed negative pressure operation has employed
by this vertical raw mill, so there is no dust during the
operation, which can help to keep the production environment clean.
5. Low wear rate and little metallic pollution: its metal wear is
only 5~10g/t.
6. With stable chemical composition and even particle size, its
products are quite easy to calcine.
