Glass with quartzite, mainly of quartz , mica minerals and may contain hematite, goethite , etc. Quartzite is a metamorphic rock composed mainly of quartz ( quartzite content greater than 85% ) , quartz sandstone and chert formed by metamorphism . And has a high hardness, water absorption than the end of fine particles, compact structure , quartzite brittle texture , good bending strength is not good , easy short crack, the higher the radiation characteristics of some varieties , so this common crushing equipment crushing boredom more difficult , it is difficult to achieve the desired results . The WKS cone crusher has a special spring safety system, which is the overload protection device allowing metallic foreign body through the crushing chamber without damage to the machine , use dry oil seal forms , make powder and oil separation to ensure reliable operation .

The current crusher equipment for crushing the short head cone crusher , medium cone crusher, impact crusher , hammer crusher , roll crusher , crushing jaw crusher machine. In recent emergence of ultra- fine crushing crusher output more granular products, and crusher design new varieties, used as a rough , broken equipment. According to the different needs of customers, the requirements in the field of crushing crushing effects of the phenomenon more common. I produced the cone crusher ( Series spring cone crusher improved model ) suitable for crushing medium hardness of various minerals and rock crushing . Quartzite has been successfully used in glass , metallurgical quartzite, limestone , calcium carbide , as well as talc crushing and cement clinker crusher .

Processed over a wide range of quartzite purposes , an important raw material for manufacturing can be glass, ceramics, metallurgy , chemicals, machinery, electronics , rubber , plastics, paint and other industries are . Quartz also has excellent heat resistance, processing different physical size , as steelmaking refractories .
