Limestone crushing process
The crushing of limestone aims at producing uniform size particles by crushing, grinding and sorting. The limestone crushing process is a multilevel process and it can be divided into primary crushing, secondary crushing and fine crushing. Primary crushing and screening take place at the mine site. Primary crushing is accomplished by using jaw crushers and impact crushers. Oversize material is passed through additional crushers and classifiers to achieve the desired particle size.
The limestone stone is then crushed and sized at a secondary crushing facility. Secondary crushing, if necessary and economic, is accomplished by using standard cone crushers followed by short head cone crushers.
The subsequent crushing is called fine crushing, and it can be achieved by using various kinds of grinding mills. For example, you can choose ball mill, super thin grinding mill, vertical grinding mill and so on.
