ادامه مطلبThey are used to grind down the concrete surface to achieve the desired degree of smoothness and shiny texture in the concrete. Like the process of sanding wood, when the grinder moves on the concrete surface, it produces fine particles of concrete dust due to grinding. After removing the concrete dust, a fine mirror-like glossy finish is obtained.
ادامه مطلبThe grinding process consumes the most energy in cement production, its energy consumption accounts for more than 70% of the total power consumption in the whole process of cement production. There are three main grinding processes in cement production: raw meal grinding, cement grinding, and raw coal grinding.
ادامه مطلبFor the manufacture of cement, the necessary raw materials must be reduced by crushing and grinding. In general, these raw materials arrive from the quarry at the beginning of the size reduction process in pieces of up to 2 meters in its largest dimension.
