Hefei Hengcheng HVM Series Coal Mill Coal Vertical Mill 60t/h Fly Ash Equipment

Product Introduction

Coal is an important energy source, widely used in metallurgy, chemical industry, cement, electric power, heating, heating, boilers, and other industries, and used to produce clean pulverized coal, activated carbon, humic acid, and so on. Clean and efficient utilization of coal has a broad prospect for further coal processing in the future.

Technical indicators of pulverized coal grinding

Production of clean pulverized coal for boiler combustion, heating, and power supply

Fineness: 200 mesh, D80-90, according to the requirements of rear end combustion

Suitable coal types: bituminous coal, anthracite, blue charcoal, etc

The production of clean pulverized coal for boiler combustion, heating, and power supply can improve the operating efficiency of small and medium-sized coal-fired boilers to 80%, while reducing the emission of harmful gases and dust, meeting national standards for energy conservation and emission reduction, and at the same time increasing enterprise benefits.

Production of humic acid fertilizers for agricultural use

Fineness: 100 mesh

Suitable coal types: lignite, weathered coal, peat, etc

Humic acid fertilizer has the advantages of soil improvement, improving crop production, and avoiding soil hardening. It is a "green and environmentally friendly" high-tech fertilizer that realizes the efficient use of coal. In recent years, there has been an increasing number of humic acid products, such as sodium humate and potassium humate, which are exported to foreign countries and have created tremendous value for enterprises.

Production of coal based activated carbon for chemical industry

Fineness: 200-325 meshes, according to the process requirements

Suitable coal types: bituminous coal, anthracite, etc

Coal based activated carbon has the characteristics of reasonable pore structure, good adsorption performance, high mechanical strength, easy to repeatedly regenerate, and low cost, which can fully reduce the purification cost. Therefore, it is widely used in the deep purification of drinking water, industrial water, and wastewater, and is deeply favored by the market. It is an effective way to further process and utilize coal and improve added value.

Pulverized coal processing and pulverizing equipment

Based on factors such as the fineness of pulverized coal feed, moisture content, and the fineness and use of the finished product, Hefei Hengcheng can help customers reasonably choose the grinding and separation process flow, and determine the type, model, and quantity of pulverizers based on production capacity and other requirements.

Technical DATA

HVM vertical grinding machine is a safe, environmentally friendly, energy-saving, and efficient advanced grinding equipment that integrates drying, grinding, powder selection, and transportation functions based on extensive absorption of advanced technologies from various vertical grinding machines at home and abroad and drawing on a large amount of engineering application experience. Through careful research, it has been designed and developed. The main performance and economic and technical indicators of the equipment have reached the international advanced level.

Working principle: The motor drives the grinding plate to rotate through the reducer, and the material falls in the center of the grinding plate from the feed inlet. At the same time, hot air enters the grinding plate from the air inlet. Under the action of centrifugal force, the material moves towards the edge of the grinding plate and is crushed by the grinding roller as it passes through the circular groove on the grinding plate. The crushed material is picked up by the high-speed airflow at the wind ring at the edge of the grinding plate, and large particles directly fall onto the grinding plate 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 plate for re grinding, and the qualified fine powder exits the grinding along with the airflow, The product is collected in the powder collecting device. Materials containing moisture are dried during contact with hot gases to achieve the required product moisture.

Product advantages:
1. Large production capacity, low energy consumption, green and environmental protection.
2. The roller sleeve can be used upside down, which is conducive to improving the output of the coal mill, reducing wear, and extending its service life.
3. Install explosion-proof devices to ensure safe production. An explosion-proof valve is installed on the upper casing to prevent the explosion of pulverized coal in the mill and ensure the safe use of the equipment.

Structural features:
1. The foot plate shaped grinding plate and tire shaped roller sleeve used in the coal vertical mill are more suitable for coal grinding.
2. Grinding roller bearings do not require special sealing. The grinding roller device adopts a pair of self-aligning roller bearings. The bearing sealing chamber extends outside the casing and does not come into contact with dust containing gases. Therefore, simple sealing can ensure that the grinding roller bearings do not enter dust and do not require sealing fans.
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 it is not necessary to install a slag discharge valve.
