The highway is consist of five layers.these are subgrade, Cushion, subbase, roadbase , wearing course. Each layer has different demands.
Our combined crushing and screening machines can help you get the following final products, and the classification of size of crushed product can be set and adjusted according to customer’s different requests. We can supply design, installation, adjustment and acceptance test for customers.
Highway stone crushing process
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 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 many highways.
Features of highway stone crushing process
1. The quality of the product is very high. Content of needle plate type is no more than 5%. A diabase in Africa, once adopted Jaw Crusher and Impact Crusher. But 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 processing of crushing.
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.
Our combined crushing and screening machines are reasonable combined with different crushers and have compacted special crossing distribution in their material processing flow design, so that they are small foot printed of fields, high quality in crushed products, low in quarry dust and they will give you high reward for your investment. Their advanced electric control panel can assure the whole process discharge smoothly, running reliable, operation easily and high efficiency in power consumption.
