How Is Cement Produced in Cement Plants | Cement Making Process
The proportioning of cement raw materials is not all the same but should be determined according to the actual situation. The proportion of raw materials of different specifications of cement is also different. Generally, the proportion of components in cement raw materials is 67-75% limestone, 10-15% clay, 0.5-1.5% iron ore and 8.5-11% coal.
