Introduction of aggregate for highway
Highway construction imposes strict requirements on particle size and sand grading of aggregate, especially for needle flake content of crushed stone. In order to solve the requirements of consistency, cleanness and particle content with size of 0.075mm with respect to particle size and grading, particle shape and particle composition, Sanme puts the new type of sand making machine in the production line to satisfy the requirements of aggregate for highway cement and asphalt.
Production process of aggregate for highway
The aggregate crushing process is divided into four stages: coarse crushing, medium fine crushing, sand making and screening.
The first stage: coarse crushing
The stone blasted from the mountain is fed uniformly by the vibrating feeder through the silo and transported to the jaw crusher for coarse crushing.
The second stage: medium fine crushing
The coarsely crushed materials are screened by vibrating screen and then conveyed by belt conveyor to impact crusher or cone crusher for medium crushing. The crushed stones are conveyed to the vibrating screen through a belt conveyor to sieve out different specifications of stones. The stones that meet the requirements of the customer's particle size are conveyed to the finished product pile through the belt conveyor. The impact crusher or cone crusher crushes again, forming a closed circuit cycle.
The third stage: sand making
The crushed material is larger than the size of the two-layer screen, and the stone is conveyed to the sand maker through the belt conveyor for fine crushing and shaping.
The fourth stage: screening
The finely crushed and reshaped materials are screened by circular vibrating screen for coarse sand, medium sand and fine sand.
Note: For the sand powder with strict requirements, a sand washing machine can be added behind the fine sand. The waste water discharged from the sand washing machine can be recovered by the fine sand recycling device. On the one hand, it can reduce environmental pollution, and on the other hand, it can increase sand production.
