Large Capacity Vertical Coal Grinding Mill For Coal Grinding Power Plant

Description

Vertical coal mill, also called vertical coal mill, pulverized coal vertical mill, pulverized coal mill, coal mill, is used in limestone kiln calcination, boiler heating industry, glass factory kiln renovation, cement plant, thermal power plant, iron and steel plant Equipment for grinding pulverized coal commonly used in other fields. The pulverized coal mines include raw coal, bituminous coal, coking coal, fat coal, gas coal, long flame coal, lean coal, etc. Hongcheng's vertical coal mill has advanced production technology, is equipped with anti-static treatment and explosion-proof device, and adopts open circuit system, which is an excellent equipment for pulverizing coal.

Product advantages

1. Large production capacity, low energy consumption, green and environmental protection.
2. The roller sleeve can be turned over for use, which not only helps to increase the output of the coal mill, but also reduces wear and prolongs its service life.
3. Install explosion-proof devices to ensure safe production. There is an explosion-proof valve on the upper shell to prevent the explosion of pulverized coal in the mill and ensure the safe use of the equipment.
4. The mill integrates the five processes of crushing, grinding, drying, powder selection and conveying. The process is simple, the layout is compact, the floor area is about 60-70% of the tube mill system, and the construction area is about 50 to 60% of the system.

Technical DATA

In terms of grinding system, aiming at the different physical and chemical characteristics of various types of materials in various industries, such as moisture, grindability, product fineness, safety, etc., we have developed highly targeted, mature, reliable, safe and efficient grinding technology and supporting equipment. The equipment is HVM type vertical mill. The processed materials range from high humidity to dry materials, from extremely difficult to easy to grind materials, and the fineness of products ranges from coarse to fine. It has a wide range of fields and a wide variety of materials. . Provide scientific and reasonable complete process plan and equipment selection of vertical mill pulverizing system, and provide integrated powder processing solutions.

【Introduction】

HVM vertical mill can produce both coarse powder and ultra-fine powder, and can produce coarse powder from 2 to 5mm for materials with different product fineness requirements (such as grinding shale, raw material for brick making in new wall material industry, sand making in construction industry) etc.) to 15 micron ultrafine powder with a pass rate of 97% (such as heavy calcium powder in the paper industry, activated carbon ultrafine powder in the chemical industry), the product fineness adjustment is highly arbitrary, and the adaptability is wide.

【Solution】

For the production of coarse powder, the type selection of vertical mill needs to adopt the structure of the powder separator with low resistance and anti-wear. At the same time, due to the large number of large particles, necessary anti-wear treatment and powder separator structure design are required to achieve reasonable powder selection output and energy consumption;

For the production of ultra-fine powder, the vertical mill should focus on the design and optimization of the powder separator. Due to the large resistance of the powder selection at this time, it is necessary to strictly control the fineness, and to prevent the large particles from running thick, excessive blade wear and damage.

Problems such as abnormal vibration caused by large internal resistance of the mill. Therefore, for materials with different product fineness requirements, it is necessary to calculate and analyze the smoothness of materials and gases in the vertical mill, especially the part of the powder separator, according to the characteristics of the material, so as to determine a reasonable structure of the powder separator (such as the rotor form, the number and angle of blades, the number and angle of stationary blades), and at the same time, necessary auxiliary means should be taken to control (such as using a sealed fan for gas sealing to effectively control the running of large particles).
