Vertical Limestone Coal Milling Machine Pulverizer ODM

High Operating Rate Vertical Coal Mill Limestone/coal / Cement Clinker Powder Grinding Mill Plant
 
Description

Coal vertical mill can be used in cement, electric power, steel, metallurgy and other industries. Due to its special technology and structure, the coal vertical mill has less dust and noise in the production process, and the output coal powder has high efficiency and excellent combustion performance. The coal vertical mill produced by our company is simple in process and compact in equipment. The fineness of pulverized coal can reach 80 μmR 3%, with stable fineness and uniform particle size.

Technical DATA

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 passing through the annular groove on the grinding disc. The crushed material is carried by the high-speed airflow at the air ring at the edge of the grinding disc, and the large particles fall directly 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 ground 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.

Product Main Features

1. Energy saving:
(1) High grinding efficiency and low energy consumption
(2) The single-machine production capacity is large, and the low-valley electricity can be used;
(3) New technologies for energy saving and consumption reduction

2. 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.

3. 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.

4. 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;

5. Low comprehensive investment cost:
It integrates crushing, drying, grinding and conveying, with simple process flow, less system equipment, compact structure layout, small footprint, open-air layout, low construction cost, and direct reduction of enterprise investment costs.

6. 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) The new type of grinding roller sealing device is adopted, 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.

Outstanding advantages:

1.  High grinding efficiency and low power consumption;
2.  Less metal consumption per unit product;
3.  The technological process is simple, and the functions of material grinding, drying and powder selection are completed at the same    time;
4.  Small footprint, compact layout, light weight of system equipment, and low investment in civil construction.
