The fine ash collected from the burned flue gas is called coal ash which is the main solid waste discharged from the coal power plant. Coal and pulverized coal mill machine begin to occupy the market. The coal ash form the grinding process can be cement and aggregate to improve the concrete performance. With industry the industry, the coal ash processing and utilizing field have been greatly expanded. Large-scale vertical mill is bound to become the preferred device in future coal ash processing industry. Coal ash is one of the industrial wastes with larger emissions in current China. Using grinding machine for coal ash treatment is the most potential utilization way up to now.

At present stage, China s annual slag discharging volume rises up to 30 million tons. With the development of power industry, the coal ash discharging volume in coal power industry will increase year by year. If a good deal of coal ash is not processed properly, the dust emission will bring about air pollution. If the coal ash is drained into river, the river will be silted up. The toxic chemicals will do harm to human body and living beings. Therefore, basing on the concept of resource saving and pollution reduction, the coal ash processing and utilizing have become a new striking field.

According to the current technology development, large-scale ultrafine grinder grinder has been able to process the ultrafine powder once and for all. Ultrafine coal ash processed by grinder has the advantages of even coexistence and high surface activity. Having coal ash in the blended directamente, a great many cement concrete materials will be saved, workability of concrete mixture improved, plasticity and stability of concrete strengthened. Some cement manufacturers even produce cement by mixing the coal ash into the different kinds of cement clinker according to the proportion of 8%. Coal ash has been widely applied to the concrete admixture, hollow bricks and backfill in construction engineering.screw classifier: With the broader and broader developing and utilizing space of coal ash, the demands for technological level of grinder become higher and higher accordingly. The traditional Raymond mill and ball mill have been unable to meet the demands for coexistence and processing capability in industrial processing. New type vertical mill, high pressure suspension and high pressure micro-powder grinder grinder are bound to become the mainstream equipment by virtue of its latest technological achievement and convenient and highly efficient performance.
