Environmentally Friendly Low Energy Consumption Limestone Grinding Production Line For Desulfurization
Description
HVM vertical mill is a new energy-saving product launched by our company to solve the technical problems of low output and high energy consumption of industrial mills. The pulverizer is a pulverizing equipment that integrates drying, grinding and powder selection. Widely used in coal chemical industry, thermal power, iron and steel, non-metallic mineral grinding and other fields.
【Technical Advantages Of Desulfurization Vertical Mill】
1. The energy saving effect is more obvious
The desulfurized limestone vertical mill can save 45-60% of electric energy compared with the traditional tube mill system due to the advanced grinding concept, simple process and small installed capacity.
2. High grinding efficiency
The grinding force can be increased by means of hydraulic pressurization, which can increase the output and improve the grinding efficiency. At the same time, there is also a limiter device, which only grinds the material to prevent the vibration or even wear of the equipment caused by accidental contact of the grinding roller and ring.
3. The equipment is environmentally friendly, with low noise, less dust, and clean operating environment
The vertical mill does not directly contact the grinding roller and the grinding disc during operation, and there is no metal impact sound of the steel balls colliding with each other and the steel balls hitting the lining plate in the ball mill, so the noise is low, 20-25 decibels lower than that of the ball mill. In addition, the vertical mill adopts a fully sealed system, the system operates under negative pressure, no dust, and the environment is clean

【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.
The Limestone Grinding Mill Vertical Roller Mill Cement produced by our company is air-swept type, widely used in the grinding of raw cement, slag, cement clinker, raw coal and other raw materials.
