Energy Conservation Vertical Roller Raw Mill For Raw Slag Limestone

Energy Conservation Vertical Roller Raw Mill For Raw Slag Limestone


Description:

Raw Meal Mill Vertical Mill Hvm Vertical Mill

【Application field】

grinding and processing of non flammable and explosive materials with humidity less than 6% and Mohs hardness less than 7 in building materials, chemical industry, metallurgy, coating, papermaking, rubber, medicine, food and other fields.

[Applicable materials]: Kaolin, barite, fluorite, talc, water slag, calcium lime powder, wollastonite, gypsum, limestone, phosphate rock, marble, potassium feldspar, quartz sand, bentonite, manganese ore and other materials with a hardness below Mohs 7.

【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 port, and the hot air enters the mill from the air inlet. Under the action of centrifugal force, materials move towards the edge of the grinding plate. When passing through the circular groove on the grinding plate, they are crushed by the grinding roller. The crushed materials are carried away at the edge of the grinding plate by the high-speed airflow at the wind ring. Large particles directly fall onto the grinding plate for re grinding. When the materials in the airflow pass through the dynamic and static separators, under the action of the rotating rotor, the coarse powder falls onto the grinding plate for re grinding. The qualified fine powder is grinded together with the airflow, The product is collected in the powder collecting device. Materials containing water are dried in the process of contacting with hot gas to reach the required product moisture.

Specifications and Technical Parameters of HVM Raw Vertical Mill

Main features of the product

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) Large production capacity of single machine, which can make use of low valley power;

(3) Vertical mill technology and equipment are energetically advocated new technologies for energy conservation and consumption reduction, which are conducive to enhancing the competitiveness of enterprises in the powder industry in the region and even in the country;

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 plate and the maintenance space of the mill are large, and the maintenance operation is very convenient;

(2) The grinding roll sleeve can be turned over for use, extending the service life of wear-resistant materials;

(3) There is no need to distribute materials on the grinding plate before starting up, and the mill can be started without load, eliminating the trouble of starting up hard;

(4) Low wear, special materials are used for grinding roll and grinding disc liner, and the service life is long;

(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 simple operation. The workshop can basically realize unmanned operation, saving operating costs;

3. Low comprehensive investment cost:

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

4. Stable product quality:

(1) The material stays in the mill for a short time, which makes it 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 limiting device of grinding roll is adopted to avoid the violent vibration caused by material interruption during the working time of the mill;

(2) A new type of roller sealing device is adopted, which makes the sealing more reliable, and no sealing fan is needed, further reducing the oxygen content in the mill, and the explosion suppression performance is more excellent.

6. Environmental protection:

(1) The whole system of HVM vertical mill has low vibration and noise;

(2) The system is sealed as a whole, operates under full negative pressure, and has no dust spillover. It can basically realize a dust-free workshop.
