Ore processing plant means that extracts and purifies some elements in the raw ore through a series of complex ore beneficiation flow and professional beneficiation equipment. The refined concentrate powder is mainly used in metallurgy and industry base.

Cement grinding plant is the final stage in the production of cement, which is separated from the finished cement production units. It mixes cement clinker with other certain amount of mixed materials for grinding, and then produces the finished cement.

Main Equipments: PE1200×1500 jaw crusher, cone crusher, vibrating scree, vibrating feeder and conveyor.
