Vertical roller coal mills

Coal is an important energy, important raw materials and metallurgy, chemical industry which is widely used. Mainly used for burning, coking, gasification, pyrolysis, hydrogenation liquefaction etc.. Coke oven gas as a fuel, but also an important raw material for chemical industry. Coal tar can be used in the production of chemical fertilizer, pesticide, synthetic fiber, synthetic rubber, paints, dyes, pharmaceuticals, explosives etc.. Coke is mainly used in blast furnace and casting, also can be used to make fertilizer, calcium carbide. Calcium carbide is plastic, synthetic fiber, synthetic rubber, synthetic chemical products.

As coal is so widly used in our life and coal combustion will release a lot of harmful gases,which brought a series of environmental pollution problems,we should constantly continued looking for clean coal technology, to make it better serve our life.

The Vertical roller coal mills maked by Shanghai Zenith Mining and Construction Machinery Co., Ltd is one advanced mill,adopting top technology domesic and abroad, and based on many years’ mill experiences.It can crush,dry,grind, and classify the materials.Vertical roller coal mills is a kind of large scale powder mill which is designed specially to solve the problems of low capacity and high consumption of industry mills. With a decade of years research of mills,vertical mill is designed and manufactured based on our advanced design idea, and in combination with the European technology and the market demand.


Low operating costs.

Combine the crushing, grinding, drying, classifier and elevator, the system of vertical mill is simple and occupation area is about 50% of ball mill system. Vertical roller mill can be installed outside, so it will reduce a large number of investment cost.

High efficiency.

Compared with ball mill,vertical mill can save energy consumption 30%-40%.
Less wear and tear. The optimized roller and the high quality raw material make the machine’s
life longer.

High drying ability.

As the hot air inside contacts directly with the material, drying ability is higher, and it saves energy. By regulating the air temperature, it can meet requirements with different humidity.

Simple and reliable operation.

Automatic control system is equipped, so the remote control makes it easy to operate. vertical roller mill is equipment with one device, which prevents the roller from contacting with the liner directly, and avoids the destructive impact and severe vibration.

Convenient maintenance.

By repairing fuel tank, rotating the arm, it is fast to replace the roller sleeve, and liner, and reduce the downtime loss.

Environmental protection.

vertical mill is with small vibration, low noise, and the overall sealing. The system works under negative pressure, so there is no dust going out. It meets the requirements of the state Environmental Protection.

Applying Area

Vertical roller coal mills not only be used in coal grinding ,but also can be widely used in such industries as cement, power, metallurgy, chemical industry, non-metallic mineral. It is used to grind granular and powdered materials into powder with required fineness.

Therefor,the vertical roller coal mills is the most ideal equipment for coal powder.
