ISO9001 Vertical Roller Coal Mill In Cement Plant Pulverizer

High Quality Vertical Roller Mill / Coal Grinding Mill Raw Coal Vertical Mill

Description

Coal vertical mill has the characteristics of low unit power consumption, small floor space, simple pulverizing system, low noise, reliable operation, etc., as well as large crushing ratio, grinding parts It has unique advantages such as long service life, small output change in the whole operation cycle, wide application range of materials, and good applicability under high and low loads.

The three grinding rollers of the vertical coal mill are driven by the rotating grinding disc to carry out the grinding operation.
After the incoming material falls on the grinding disc through the central coal falling pipe, the centrifugal force generated by the rotating grinding disc transports it to the grinding roller table for grinding.
The grinding pressure is generated by a spring or hydraulic pressure device. Through a statically indeterminate three-point system, the grinding force is evenly transmitted to the three grinding rollers, and the pressure is transmitted to the foundation through the pressure system. Drying and conveying of pulverized coal are carried out by hot air. The hot air is evenly distributed around the grinding disc through the nozzle ring, and the ground material is dried and transported to the separator on the upper part of the mill. The coarse and fine powder of the material is separated here, the fine powder is discharged from the mill, and the coarse powder is returned to the mill for grinding.
Some unbreakables in the material can be discharged through the ballast outlet at the lower part of the mill. The coal mill is mainly composed of the basic part, the reducer, the lower frame machine, the middle frame machine, the grinding disc, the grinding roller, the pressurizing device, the separator, the positive pressure air sealing device, the steam purging device and other components, and is also equipped with the main motor , Lubricating oil station, hydraulic station and sealing fan and other auxiliary equipment, and also equipped with slow transmission device, special tools for installation and maintenance, escalator platform, pulverized coal distributor, quick-break valve and other supporting equipment for users to choose. The coal mill adopts a hydraulic pressure system, which can adjust the grinding pressure during operation, and has better protection performance of iron passing.
On the basis of the original standard type, a grinding roller turning device is added, and the anti-knock ability of the grinding body is improved.

Technical DATA

Outstanding advantages:

1. 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.

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 mill technology and equipment is a new energy-saving and consumption-reducing technology vigorously advocated, which is conducive to enhancing the competitiveness of enterprises in the powder industry in the region and even the whole country;

3. Low comprehensive investment cost:

It integrates crushing, drying, grinding and conveying. The process is simple, the system equipment is small, the structure layout is compact, and the floor area is only 50% of the ball mill. It can be arranged in the open air, and the construction cost is low, which directly reduces the investment cost of the enterprise.

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. 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.

6. 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;
