Coal Mill in Cement Plant

The ball mill is a traditional coal pulverizer machine, which has been widely used since it was invented. In the cement plant, the new dry process cement manufacturing requires the moisture content of coal powder to be 0.5% ~ 1.5%, while that of raw coal is 1.5% ~ 4.0%. Therefore, the ball mill should have a drying function besides grinding.

The water is exposed to air as it flows throughout the cooling tower. The air is being pulled by an motor-driven electric "cooling tower fan". When the air and water come together, a small volume of water evaporates, creating an action of cooling. The colder water gets pumped back to the process/equipment that absorbs heat or the condenser.
