The characteristics of highway road surface concrete aggregate processing

1.    Product quality is excellent,

2.    Price and gradation is reasonable,

3.    The grain shape is good,

4.    The needle flake content rate is less than 5%.


A basalt Crushing in Jilin Province directly uses the Jaw crusher and Impact Crusher process, not only resulting in serious wearing but also making needle flake content rate more than 10%. Thus, the product sales is bad, failing to meet the requirement of the highway. But with the technical renovation of the VSI Series high efficient vertical shaft impact crusher, the needle flake content rate reduces to 4.8%.

Compared with other crusher and processing line, VSI is :

A. With the excellent stone finishing ability, whatever it is basalt, diabase, limestone or andesite,the needle flake rate is below 5%, which is incomparable by PF impact crusher. It is the best machine to produce good shape grain stone recognized by both international and domestic.

B. More shaping and less crushing. It generates less stone powder, improves the service life of wearing parts, and reduces the unit power consumption.

C. According to the needs of stone shaping, it absorbs the design of Metso, Sandvik, with the performance reaching international level.

VSI series stone finishing machine can be used for both the old production line modification to improve the stone quality and can cooperate with the company development of high performance concrete (C40 above.their) aggregate (stone) production line, which makes you become the beststone production enterprise with leading technology and good benefit.
