Stone Crushing Plant

In the production process, large stones are evenly sent to the jaw crusher by a vibrating feeder for coarse crushing (primary crushing), then sent to the impact crusher by the belt conveyor for secondary crushing. After that, all the stones will be divided into three different sizes on the vibrating screen.

Cement - Cement - Extraction and processing: Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.
