Basalt  uses
Basalt is an igneous volcanic rock that is dark grey to black in colour. Basalt is used as aggregate in construction. When crushed, it can be used as road base. It is also polished and used as floor tiles.
No matter Superpave pavement technology is adopted, asphalt road surface of high way has a high requirement for aggregate shape and size proportion, especially for content of thin and flaky grain. Under this condition the traditional technics adopting impact crusher can not meet the requirement, new crushing and screening techinics adopting VSI sries vertical shaft impact crusher is developed by our company, which can meet highway pavement perfectly. Qualify aggregate produced by this technics has been widely used in construction of many highways.

1. High aggregate quality, content of thin and flaky grains less than 5%. Jaw crusher and cone crusher crushing technics is used in a dolerite mine in Africa, among finished products content of thin and flaky grains is more than 10%, thus bag sales is resulted.After technology reconstruction using VSI vertical shaft impact crusher in this time, content of thin and flaky grains be reduced to 4.7%.
2. Compared with production line using cone crusher as the last crushing procedure, the capacity increases by 50%.
3. As cone crusher is only the secondary crusher, wearing parts consumption of VSI sries vertical shaft impact crusher is very limited, and total wearing parts consumption of complete production line be decreased significantly.
