A key concern of any cement plant is the availability of the critical processing equipment, particularly crushing and grinding machines. The handling of very abrasive material, together with 24/7 operation makes the cement industry one of the most wear-prone enviroments for production machinery.
Baghouses are designed based on the size of the cement baghouse building and the volume of the dust emissions. Large plants tend to have more numerous and larger baghouses than small plants. For example, a cement plant that has a production capacity of 1 million metric tons per year will have around six to eight baghouses.
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%.
