Aggregate for highway building

Aggregate for highway building Introduction

In the construction of expressway, high requirements are placed on the aggregate shape and gradation of concrete aggregates, especially the pin-like content in basalt (diabase) gravel. In order to solve the requirements of particle size and gradation, particle shape, consistency of particle composition, cleanliness and particle content of 0.075mm, Dewo has added a new sand making machine in the production line configuration to better meet the highway cement and asphalt. Wait for the requirements of sand and gravel aggregates.

Applicable materials: granite, basalt, diabase and other hard materials

Application areas: highways, urban construction, airport construction and other industries

Equipment configuration: vibrating feeder, jaw crusher, hydraulic cone crusher, circular vibrating screen, vertical shaft impact crusher, belt conveyor

Expressway aggregate production process

The mined stone is firstly fed by the vibrating feeder to the jaw crusher for preliminary crushing. The secondary crushing is completed by the cone crusher. The material broken by the cone is sieved on the vibrating screen. The material larger than 40mm is returned to the cone and broken again. A closed loop is formed, and the material less than 40 mm enters the vertical impact to break and shape. The finished product sieved by the vertical impact material is sieved, and the returning vertical impact breaking cycle of more than 20 mm is broken, and the materials less than 20 mm are conveyed to the respective finished material piles by the belt conveyor.

Expressway aggregate production line performance

1. The sandstone production line is highly automated;

2. It has high production efficiency, low operating cost, large output and high profit;

3. The size of the discharge material is adjustable, the breaking rate is high, and energy saving;

4. The finished stone has uniform particle size and good granular shape, which is in line with the national high-speed material standard.
