Crushing
During cement manufacturing process, the majority of raw materials, including limestone, clay, iron ore, coal, etc. will be crushed. Specifically, due to larger granularity and higher hardness, the crushing of limestone that is maximally consumed in cement process plays critical role in the raw material crushing.
Pre-homogenization
Pre-homogenization means during the course of raw material storing and reclaiming, scientific material stacking and reclaiming techniques are utilized to achieve preliminary raw material homogenization, thus assuring the raw material storage yard of double function, namely storage and homogenization.
