Introduction Of Cement Production Line
Cement grinding is not only the final process of cement manufacturing, but also the most power-consuming process. Its main function is to grind the cement clinker as well as other materials like gelling agent, performance regulating material, etc. to the suitable particle size, which is expressed by fineness, specific surface area, etc. This is to form a certain particle gradation, to increase its hydration area, to accelerate the hydration rate, and to meet the requirements of cement paste condensation and hardening. The production of cement generally can be divided into three steps: raw material preparation, clinker calcination and cement making. Cement grinding plant also has other names, for example, cement clinker grinding plant and cement grinding station.
Process of Cement Grinding and Main Eequipment
In the process of cement production station, every ton of portland cement produced should grind at least 3 tons of materials (including all kinds of raw materials, fuel, clinker, mixture, gypsum). According to statistics, the power consumed in the grinding operation of dry cement production line accounts for more than 60% of the power of the whole plant, in which raw material grinding accounts for more than 30%, coal grinding accounts for about 3%, and cement grinding 40%. Therefore, reasonable selection of grinding equipment and process flow, optimization of process parameters, correct operation and control of operation system are of great significance to ensure product quality and reduce energy consumption.
Advantages of Cement Production Line
The cement grinding plant is usually built in the coal mining area, which is near the cement sales market in medium and large cities. Cement admixture is mostly from industrial waste produced by the city, and cement grinding plant can greatly dispose of the slag, fly ash, cinder, coal gangue and other industrial waste near the city, which is a green and environmental protection industry.
