Highway Stone Crushing Process
Aggregate is the raw materials for highway. Asphalt concrete pavement and groundwork is consist of aggregate. Both in SMA or Superpave Pavement Technology of make asphalt concret pavementthe shape and rank of aggregate has been brought up a very high demand. Especially to the content of needle plate type in the basalt, the former impact crusher processing chart cannot meet the requirement any longer. Therefore, our company puts up the newest crushing and screening processing chart-VI series of Vertical Shaft Impact Crusher to meet the need. The high-quality aggregate produced by this production line is widely used in road surface of highways.
The machine of crushing process:
1. Vibrating Feeder
2. PE/PEW Series Jaw Crusher
3. PF Series Hard Rock Impact Crusher or Cone Crusher
4. Vibrating Screen
5. VSI Series Vertical Shaft Impact Crushers
The features of the processing:
1. The quality of the product is very high. Stones with needle plate type is no more than 5%. The diabase in Africa, if crushed by Jaw Crusher and Impact Crusher, content of needle plate type is more than 10%, resulting the bad sell of its product. After using VSI Series Vertical Shaft Impact Crushers, the content of needle plate type in the product is reduced to 4.7%.
2. The production improves 50% compared with useing Impact Crusher as the final crushing processing.
3. Because we use Impact Crusher as the secondary crusher, and Vertical Shaft Impact Crusher consumes little metal, the consumption of wear-parts is reduced greatly in the whole process.
