What is a completed coal gangue powder vertical mill?

Coal gangue belongs to solid waste residue. The high recycling value of coal gangue is the development trend of solid waste residue in the future. How to grind coal gangue with vertical mill?

Technological process of coal gangue vertical mill

As solid waste residue, Guikuang recommends the use of vertical mill equipment to help the production and grinding. The equipment is an energy-saving and environment-friendly representative pulverizer. The process flow includes crushing, pulverizing, grading and powder collection.

Crushing: crushing raw ore with crusher.

Grinding: materials enter the grinding roller table and are continuously squeezed, ground, sheared and crushed under the pressure of the grinding roller.

Classification: the hot air is ejected from the air ring around the grinding disc at high speed and evenly upward. The milled materials are blown up by the high-speed air flow at the air ring. On the one hand, the materials with coarse particle size are blown back to the grinding disc for re grinding, on the other hand, the suspended materials are dried, and the fine powder is brought into the classifier by the hot air for classification.

Powder collection: the qualified fine powder flows out of the mill with the gas and is collected by the dust collection equipment as the product.

Introduction of advantages of vertical coal gangue pulverizer

What are the advantages and characteristics of the vertical grinding mill equipment? As a special equipment dedicated to the field of solid waste residue, the coal gangue vertical mill equipment is environmentally friendly, energy-saving, efficient and high-yield. It has a wide range of grinding fields (used in many markets such as solid waste residue, non-metallic ore, coal mine, thermal power plant and cement plant), and there are rich types of grinding (grinding high humidity materials, dry materials, difficult grinding materials, easy grinding materials, etc.) to see its technical parameters.

[Finished product fineness]: 22-180μm

[production capacity]: 5-700t / h

[grinding field]: it is aimed at various non-metallic mineral materials with Mohs hardness below grade 7 and humidity within 6%. The mill is widely used in power, metallurgy, cement, chemical industry, rubber, coating, ink, food, medicine and other production fields.

[performance characteristics]: it integrates drying, grinding, grading and conveying. It has the characteristics of high grinding efficiency, low power consumption, large feed particle size, easy adjustment of product fineness, simple equipment process flow, small floor area, low noise, low dust, simple use and maintenance, low operation cost and low consumption of wear-resistant materials.
