Factory Large Capacity Slag Coal Vertical Roller Grinding Mill Machine Production Line

Description

Slag vertical mill is a large grinding equipment developed by our company with advanced European technology. It integrates fine crushing, drying, grinding, powder selection and transportation. It has the characteristics of small floor area, simple process flow, high grinding efficiency, low energy consumption, low noise, large drying capacity, easy adjustment of product fineness, no dust pollution, convenient maintenance and reliable operation. Especially in large grinding process, it can fully meet the high production demand of customers.

Slag vertical mill is widely used for large-scale material grinding and ultra-fine grinding of water slag, slag, slag and other materials in metallurgy, electric power, cement, chemical industry, ceramics, non-metallic minerals, and power plant desulfurization. The equipment has strong material drying capacity and saves energy. By adjusting the temperature of hot air, it can meet the requirements of materials with different humidity.

【Working Principle】: The motor drives the grinding plate to rotate through the reducer, the material falls in the center of the grinding plate from the feed inlet, and the hot air enters the grinding plate from the air inlet. Under the action of centrifugal force, the material moves towards the edge of the grinding plate and is crushed by the grinding roller when passing through the circular groove on the grinding plate. The crushed material is carried up at the edge of the grinding plate by the high speed air flow at the wind ring, and the large particles directly fall on the grinding plate for re-grinding. When the material in the air flow passes through the dynamic and static separator, under the action of the rotating rotor, the coarse powder falls on the grinding plate for re-grinding, and the qualified fine powder comes out with the air flow, The product is collected in the powder collecting device. The material containing moisture is dried during the contact with hot gas to reach the required product moisture.

 
Technical Data

Product Advantages

1. High efficiency and energy saving:
(1) The grinding efficiency is high and the energy consumption is low. Compared with the ball mill, the energy consumption is 40% - 50% lower;
(2) The single machine has large production capacity and can use low valley power;
(3) The vertical mill technology and equipment is a new energy saving and consumption reduction technology vigorously advocated, which is conducive to improving the competitiveness of enterprises in the area and even in the national powder industry;

2. Easy maintenance and low operation cost:
(1) The grinding roll can be turned out of the machine by hydraulic device. The replacement of the roll sleeve liner and the maintenance space of the mill are large, and the maintenance operation is very convenient;
(2) The roller sleeve of the grinding roller can be used upside down, extending the service life of the wear-resistant material;
(3) There is no need to put cloth on the grinding plate before starting, and the mill can be started without load to avoid the trouble of starting;
(4) Low wear, special materials are used for grinding roller and grinding plate liner, with long service life;
(5) High degree of automation: the automatic control technology adopts Siemens series PLC from Germany, equipped with automatic control system, which can realize remote control and easy operation. The workshop can basically realize unmanned operation and save operating costs;

3. Low comprehensive investment cost:

It integrates crushing, drying, grinding and conveying. The process flow 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. Stable product quality:

(1) The material stays in the mill for a short time, so 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.

5. High reliability

(1) The grinding roller limit device is adopted to avoid the severe vibration caused by material breaking during the working time of the mill;
(2) The new roller sealing device is adopted, which makes the sealing more reliable, and no sealing fan is required, further reducing the oxygen content in the mill and improving the explosion suppression performance.

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 overflow, basically realizing a dust-free workshop.
