Large Capacity 28 t / h Pulverized Vertical Coal Mill Production Line Process Equipment HVM1700 Coal Mill

Product Introduction

Vertical coal mill, also known as coal mill and coal vertical mill, is a high-efficiency and energy-saving pulverized coal production equipment. It is suitable for grinding medium-hard materials such as raw coal and bituminous coal. It can be widely used in electric power, metallurgy, building materials, Pulverizing systems in chemical and other industries, especially in a large number of coal injection pulverizing systems that use bituminous coal.

The roller type coal mill is a new type of vertical mill for energy saving and consumption reduction developed by Hefei Hengcheng in combination with domestic and foreign experts and scientific research institutes. Low;

It adopts optimized grinding process to ensure high uniformity of pulverized coal, and the compound separator greatly improves the efficiency of powder separation, which is the correct choice for the new type of coal pulverizer.

【Application field】
Building materials, chemical industry, metallurgy, electric power, pulverized coal preparation and other industries.

【Applicable materials】
Bituminous coal, anthracite, lignite, etc.

Technical DATA

【Characteristics】

1. High grinding efficiency and low grinding energy consumption. Compared with the traditional air-swept ball mill of the same scale, the power consumption of grinding can save 20-40% of electricity, especially when the moisture content of the raw coal is large, the electricity saving is greater.

2. Great drying capacity. The vertical coal mill adopts air-swept operation. By adjusting the air temperature and air volume, it can grind raw coal with a moisture content of up to 20-30%. The drying capacity of the air-swept ball mill is limited, while the use of a vertical coal mill can solve its high moisture requirement with a large air volume.

3. The particle size of the incoming grinding is large, which can reach 5% of the diameter of the grinding roller, so the secondary grinding can be omitted for large and medium-sized mills.

4. The fineness of the product can be easily controlled by adjusting the rotor speed of the static and dynamic separator, and the fineness of pulverized coal can reach R0.08≤2%. And the fineness is stable and the particle size is uniform, which is conducive to the combustion of pulverized coal, and is very suitable for grinding inferior coal and anthracite.

5. The process flow is simple, the floor area is small, the building area is small, and it can be arranged in the open air. The vertical mill integrates the five processes of crushing, grinding, drying, powder selection and conveying.

6. Low noise, less dust, and clean operating environment. The noise of vertical mill is only 80-85dB, which is 20-25dB lower than that of ball mill. The system works under negative pressure, no dust is flying, and the operating environment is clean.

7. The grinding body consumes less and has a long service life. High operating rate. Because the vertical mill is equipped with a limit device, there is no direct contact between the vertical mill roller sleeve and the lining plate, the vibration amplitude of the mill is small, the life of the grinding body is long, and the running rate is high.
