Coal is the mainly energy consumption, so it is the main problem to improve coal fired efficiency for thermal power plant. Traditional ball bill has large power consumption in the process of production, and fineness of pulverized coal is not up to the standard. Great Wall Machinery put forward coal vertical roller mill solution for power plant, which can effectively improve fineness of pulverized coal, improve combustion ratio, and reduce operation costs of power plant.
1. Enhancing the combustion efficiency of pulverized coal, the energy consumption reduces by 30%, which fulfills the national standard.
2. The working mechanism being changed, reducing the worn-out and prolonging the life time, the operating costs is reduced.
3. High degree of homogenization, short grinding time and high production efficiency.
Characteristics of Solution
1. Low power consumption of coal vertical roller mill (about 7-8 kWh/t) and long life time of grinding parts. High separation efficiency and excellent homogenization.
2. With reasonable overall structure, stable performance, simple operation, obvious energy-saving effect, the main technological and economic indicators of this solution reach the international advanced level.
3. High crushing ratio and long life time of grinding parts, wide scope of application to materials, good applicability with high and low load.
4. Low investment costs and stable product quality.
5. The noise is low and the equipment is sealed integrally, no dust overflowing. The environment is clean, fulfilling the national environmental requirements.
