Description
What is cement vertical mill?
Cement vertical mill is mainly used for the grinding production of cement clinker. In recent years, with the improvement of vertical mill design and manufacturing technology, as well as the innovation of grinding process, vertical mills have been successfully applied as cement final grinding equipment abroad. Used in the cement industry with annual production of 300000, 600000, 100, 1.2, 1.5 million tons and other industries to meet users' requirements for different production and material grinding.
Working Principle
The motor drives the grinding disc to rotate through the reducer, the material falls into the center of the grinding disc from the feed inlet, and the hot air enters the mill from the air inlet. Under the action of centrifugal force, the material moves to the edge of the grinding disc, and is crushed by the grinding roller when it passes through the annular groove on the grinding disc. Re-grinding, when the material in the airflow passes through the dynamic and static separator, under the action of the rotating rotor, the coarse powder falls on the grinding disc for re-grinding, and the qualified fine powder is milled together with the airflow and collected in the powder collecting device, which is product. Moisture-containing materials are dried during contact with hot gas to achieve the required product moisture.

Advantages of our products
1. Low comprehensive investment cost
It integrates crushing, drying, grinding and conveying, with simple
process flow, less system equipment, compact structure layout and
small footprint.
2. High efficiency and energy saving
(1) High grinding efficiency and low energy consumption, compared
with ball mills, the energy consumption is 40%-50% lower;
(2) The single-machine production capacity is large, and the
low-valley electricity can be used;
(3) Vertical grinding technology and equipment is a new technology
for energy saving and consumption reduction vigorously advocated
3. Easy maintenance and low operating cost
(1) The grinding roller can be pulled out of the machine by
hydraulic device, the replacement of the roller sleeve lining plate
and the maintenance space of the grinding machine are large, and
the maintenance operation is very convenient;
(2) The roller sleeve can be turned over for use, extending the
service life of the wear-resistant material;
(3) There is no need to put cloth on the grinding disc before
starting the machine, and the mill can be started with no load,
eliminating the trouble of difficult starting;
(4) The wear is low, the grinding roller and the grinding disc
lining are made of special materials, and the service life is long;
(5) High degree of automation: The automatic control technology
adopts German Siemens series PLC, equipped with automatic control
system, which can realize remote control and easy operation. The
workshop can basically realize unmanned operation and save
operating costs;
4. High reliability
(1) The grinding roller limit device is used to avoid the violent
vibration caused by the material cut off during the working time of
the mill;
(2) Adopting a new type of grinding roller sealing device, the
sealing is more reliable, and there is no need to seal the fan,
which further reduces the oxygen content in the mill and has better
explosion suppression performance.
5. Stable product quality
(1) The material stays in the pulverizer for a short time, and it
is easy to detect the particle size distribution and composition of
the product, and the product quality is stable;
(2) The product has uniform particle shape, narrow particle size distribution, good fluidity and strong product adaptability.
6. Environmental protection
(1) The whole system of HVM vertical mill has small vibration and
low noise;
(2) The system is sealed as a whole, operates under full negative
pressure, and has no dust spillage, which can basically realize a
dust-free workshop.
