Vertical Coal Grinding Mill For Manufacturing Plant High Efficiency

High Efficiency Vertical Roller Mill Powder Grinding Machine

10 - 90 t / h HVM Series Vertical Coal Grinding Mill For Pulverized Coal Production Line

Product Introduction

A coal mill is a machine that crushes coal blocks and grinds them into coal powder. It is an important auxiliary equipment for a coal powder furnace. The coal grinding process is the process of coal being crushed and its surface area continuously increasing. To increase the new surface area, it is necessary to overcome the binding force between solid molecules, which requires energy consumption. Coal is ground into coal powder in a coal mill, which is a safe, environmentally friendly, energy-saving, and efficient advanced grinding equipment that integrates drying, grinding, powder selection, and conveying functions.

The Hefei Hengcheng HVM vertical pulverizer for coal powder has advantages such as 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 operating costs, and low consumption of wear-resistant materials.

It can be widely used in power, metallurgy, cement, chemical industry, non-metallic ore and other industries, mainly for grinding raw cement, clinker, desulfurization limestone powder of power plant, slag powder, manganese ore, gypsum, coal, barite, calcite, bauxite and other materials.

Working principle: The electric motor drives the grinding disc to rotate through a reducer, and the material falls into the center of the grinding disc from the feeding port. At the same time, hot air enters the grinding chamber from the air inlet. Under the action of centrifugal force, the material moves towards the edge of the grinding disc and is crushed by the grinding roller when passing through the circular groove on the grinding disc. The crushed material is carried up by the high-speed airflow at the edge of the grinding disc, and large particles directly fall onto the grinding disc for 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 onto the grinding disc for re grinding, and qualified fine powder is discharged with the airflow, Collect in the powder collection device, which is the product. Materials containing water are dried in the Contact process with hot gas to meet the required product moisture.

Technical DATA

Product advantages:
1. Large production capacity, low energy consumption, green and environmentally friendly.
2. The roller sleeve can be used upside down, which is beneficial for increasing the output of coal mills, reducing wear, and extending its service life.
3. Install explosion-proof devices to ensure safe production. The upper shell is equipped with an explosion-proof valve to prevent the explosion of coal powder in the mill and ensure the safe use of the equipment.

Structural features:
1. The foot shaped grinding disc and tire shaped roller sleeve used in the coal vertical mill are more suitable for coal powder grinding.
2. Grinding roller bearings do not require special sealing. The grinding roller device adopts a pair of self-aligning roller bearings, and the bearing sealing chamber extends to the outside of the machine casing, avoiding contact with dusty gases. Therefore, a simple sealing can ensure that the grinding roller bearings do not enter dust and do not require sealing the fan.
3. The transmission part of the mill does not require an auxiliary transmission device.
4. The slag removal part is simple. The coal vertical mill has less slag discharge, and the slag discharge port is equipped with a cover plate, so there is no need to install a slag discharge valve.
