Highway Stone Crushing Plant and Process
Asphalt concrete is a kind of mixture, and it is mixed under strict conditions. It is mainly made up of mineral aggregates with certain gradation (like gravel, rubble, stone chips, sand, and mineral powder, etc.) after artificial matching and a certain proportion of asphalt materials for road use. In asphalt concrete pavement, the demand on the shape and gradation of aggregate is very high. Especially to the content of needle plate type in the basalt, the old impact crusher cannot meet the requirement any longer.
Among the highway stone production plant, VSI series vertical shaft impact crusher, which you can also call VSI sand making machine, plays a quite important role. DSMAC VSI series impact crusher is designed by reputed German expert of DSMAC and every index of VSI crusher is in world's leading standard. Nowadays, VSI crusher has replaced hammer crusher, roller crusher, roller ball mill etc. and become the mainstream equipment in sand making business.
Thus, our company has designed and developed the high-performance vertical shaft impact crusher through the absorption of advanced technology from home and abroad and independent technical innovation. The high-quality aggregate produced by our crushing equipment is widely used in highway pavement.
1. The final products are with high quality. There is a low content of needle plate type with no more than 5%.
2. The output has been improved by 50% in comparison with adopting impact crusher as the final crushing process.
3. As impact crusher is used for secondary crushing, and vertical shaft impact crusher consumes little metal, there is a low consumption of wear-parts in the whole process.
High ways need exacting quality stones. The quality of stones includes two terms: its physical property and processing characteristic. We cannot control the physical property of stone, but we can decide the size of stones we need. Processing characteristic of stones used in high way construction should be at least even shape, the control methods of broken stone diameter, gradation, composition, content of grain less than 0.
Asphalt concrete pavement is used in either SMA or Superpave Pavement Technology, the 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 Vertical Shaft Impact Crusher to meet the need. The high-quality aggregate produced by this production line is widely used in road surface of many highways.
Stationary type for aggregate feeding, we have Skip Hopper type (25m3/h ~75m3/h) and Delivery Belt type(60m3/h ~ 240m3/h)
All hauling mobile plant use large angle Groove belt for aggregate feeding.
