In the highway asphalt concrete road surface, both SMA and Super pave technology assign high requirement of the shape and rank of aggregate. 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 put up the newest crushing and screening processing chart-VI series Vertical Shaft Impact Crusher to meet the need. The high-quality aggregate produced by this production line was widely used in SMA road surface of Shenyang-dalian highway.
