Vertical Grinding Mill

Brief Introduction to Vertical Grinding Mill:

Vertical grinding mill is developed on the basis of years of experience and domestic and foreign advanced technologies. Vertical grinding mill is an ideal grinding machine that integrates crushing function, drying function, grinding function and screening function. Vertical grinding mill is widely used in cement, electric power, metallurgy, chemical industry, non-metallic mineral industry and other industries.

More than 200Type Applicable materials

Applied material: Non-Metalic ore, like limestone, gypsum, dolomite, potassium feldspar, barite, talc, diabase, quartzite, bentonite, etc.

Applied fields: Grinding of metallurgy, building materials, chemical industry and other mineral materials

It can process non-flammable and non-explosive mineral materials with Moh's hardness below 9.3 and humidity below 15%, and the fineness of the finished products can be adjusted from 0.84mm - 0.37mm (20 mesh - 400 mesh), and the capacity can up to 320 tons per hour.

Advantages

1. Clean and Environmentally Friendly: Dust-free workshop with no dust leakage, reliable sealing, and a dust removal rate of up to 99.95%.

2. High Degree of Automation: Fully automatic control system with remote operation, making it simple and convenient.

3. 20% Reduction in Overall Cost: Integrates crushing, grading, drying, and conveying into one system, saving the cost of an additional drying unit.

4. High Efficiency and Energy Saving: Saves 30%-50% more power compared to ball mills, with high grinding efficiency and fineness up to 800 mesh.

Working Principle of Vertical Grinding Mill:

When vertical grinding mill works, driven by engine through the speed reducer, the grinding plate rotates. Materials are fed into the central part of the grinding plate through the feeding machine and at the same time, hot air is enters into the cavity from the air intake. With the rotation of grinding plate, under the function of centrifugal force, materials moves towards to the margin of the grinding plate and got ground by grinding roller when the materials across the circular groove.

After being ground, materials are driven by the hot air and the large particle materials will fall into the grinding plate to be reground. Materials in the air will be carried to the upper powder concentrator and the coarse powder will fall from the cone hopper to the grinding plate to be reground. The qualified powder will out of the grinding machine together with air and after cross the dust collector, final product is done. Materials that contain water content are dried in the process of contacting with hot air.
