SOLUTION

A Coal Grinding Mill Plant is an industrial facility that crushes and grinds coal into powder, widely used in industries such as electricity, steel, and cement to improve coal combustion efficiency and reduce environmental pollution. In the whole system, the preparation of pulverized coal is a very important part. The quality of coal powder formed by raw coal processing determines the operational efficiency of the entire system. Due to the high demand for production capacity, ordinary coal mills cannot meet market demand, and more and more customers are turning their attention to large coal mills. Below is an introduction to the main equipment and process flow of the coal mill factory:

1. Main equipment of Coal Grinding Mill Plant

The core equipment of a Coal Grinding Mill Plant includes coal grinding mills, powder concentrators, dust collectors, and coal powder conveying systems. According to different process requirements, factories can choose suitable equipment.

Coal mill: used to crush raw coal and grind it into coal powder. Common types include HGM Ultra-fine Grinding Mill、Vertical Roller Mill、MTM Dolomite Grinding Mill、YGM Raymond Grinding Mill. Among them, vertical grinding has become the mainstream choice in recent years due to its high efficiency and environmental friendliness.

Powder selection machine: used to grade the ground coal powder according to particle size, with coarse powder returning to the coal mill for regrinding and fine powder entering the coal powder storage bin for storage.
Dust collector: used to collect dust generated during coal powder processing. Common types include pulse bag dust collectors and high-efficiency explosion-proof pulse bag dust collectors.

Coal powder conveying system: including screw conveyor, pneumatic conveying system, etc., used to transport coal powder from the coal powder silo to the boiler or burner.

2. Process flow of Coal Grinding Mill Plant

The particle size of coal powder usually ranges from a few millimeters to tens of micrometers, with a large specific surface area and good flowability. The preparation process of coal powder includes two stages: drying and grinding.

Drying: Before entering the coal grinding mill, raw coal usually needs to be dried to reduce moisture content and improve grinding efficiency.

Grinding: Raw coal is ground into coal powder in the coal grinding mill, and the ground coal powder is classified by the powder selector. Qualified coal powder is stored in the coal powder bin.

Application: Coal powder is mainly used in industrial equipment such as coal-fired boilers and cement kilns to improve combustion efficiency and reduce harmful gas emissions.

3. Safety and environmental protection measures for Coal Grinding Mill Plant

In practical application, the explosion-proof function of the coal pulverizer for pulverized coal processing is also a highlight of our equipment. In the process of coal powder processing, dust explosions are prone to occur, posing a great threat to production safety. The coal powder preparation system adopts nitrogen inerting technology and five level explosion-proof equipment in the mixed coal grinding process. Key components are equipped with explosion-proof valves to prevent equipment damage. At the same time, the model is also equipped with an intelligent control system that can achieve remote monitoring and automatic adjustment, ensuring safety and stability in the production process.

4. Application areas of Coal Grinding Mill Plant

Coal powder plants are widely used in the following fields:

Power industry: Coal fired power plants use coal powder as fuel to improve combustion efficiency and reduce pollutant emissions.

Cement industry: Cement plants use coal powder as fuel to replace some petroleum coke or natural gas, reducing production costs.

Steel industry: Steel companies use coal powder as fuel to improve the utilization rate of coal injection into blast furnaces.

Chemical industry: Coal powder can be used to produce deep processed products such as coal based activated carbon and humic acid fertilizers.
