Mine including coal, metal ores, non-metallic minerals, building materials and chemical ore mine and so on. All mining process are unavoidable for ore processing, including metal ore crushing, beneficiation, milling and non-metallic ore crushing, grinding. With the depletion of the resources of various mining, mining technology by the original rough model into a modern fine mode. Gradually will be effective mining, fine crushing. So how effective the various ore processed effectively, rapidly increase their value ore, mining crushing production line configurations reasonable choice is a top priority.

	Non-metallic mineral mining are mainly used for making construction material, such as building sand, constrction materials, infrastructure aggregate, etc. Plant configuration mainly according to customer specifications for stone, capacity and use. Kefid machinery provide a comprehensive construction program design and technical support according to customer’s requirement. The entire production line generally consists of feeder, jaw crusher, impact crusher, vibrating screen, belt conveyor, centralized electric control and other equipment, also according to the customer‘s actual installation conditions supporting the design of non-standard components.

	After mining, ore will feed into a large jaw crusher for primary crushing, then through hydraulic cone crushing machine, after crushing, ore sent to the vibrating screen for screening. In the process of grinding the ore, the ore into the mill had been treated exclude backward into the cyclone classification, grading qualified products stirred tank overflow into the flotation machine. Flotation machine causes the pulp, mixing the drug and the air, and then forming a bubble floating in the above, the mineral is scraped out blade，and then enter the outflow washed out with water inside a trench. This is the complete process of refining the ore.
