With China's high-speed, high-speed railways, bridges, highways, the construction efforts continue to increase, the demand for sand and gravel material has also grown. And the vast majority of railroads, highways, bridges, hydropower stations and other large-scale projects, the demand for stone is relatively large, the requirements of stone is also very high, so in the purchase of quarry crushing equipment is best to choose the equipment advanced, technically reliable, good technology, good after-sales service manufacturers in order to ensure that the quality of the stone materials needed for the project.
Quarry equipment required include: feeder, jaw crusher, impact crusher, cone crusher, vibrating screen and other equipment. The equipment is connected with belt conveyor, and the width and length of the conveyor are designed according to the site.
Sand and gravel production line
Quarry workflow: silo ---- feeder --- jaw crusher ---- impact crusher ---- vibrating screen ---- finished stone. The stone is evenly fed into the jaw crusher by the feeder for preliminary crushing, then the coarse material produced is conveyed to the impact crusher by the belt conveyor for further crushing, and the finely crushed stone is fed into the vibrating screen to screen out the different specifications of the stone, and the stone returned which doesn't meet the requirements of the particle size is fed into the impact crusher for crushing again.
The whole production line is mainly used for crushing limestone, granite, river pebbles, basalt and other rocks. The quality of the finished products after crushing fully meets the GB14685-2001 standard, providing qualified aggregates for higher highway, railroad, water conservancy, concrete mixing plant and other industries. The whole production line has high automation program, large crushing ratio, high production efficiency and large processing capacity. The crushed product is in cubic shape, with low content of needle and flake, no internal crack, and high compressive strength. The maintenance of the equipment is easy, and the wear parts adopt the latest high strength wear-resistant materials, with small loss and long service life, which can bring considerable economic benefits for the customers.
