Sand Quarry And Mining Equipment

Industrial sand and gravel typically are mined from open pits of naturally occurring quartz-rich sand and sandstone. Mining methods depend primarily on the degree of cementation of the rock. In some deposits, blasting is required to loosen the material prior to processing. The material may undergo primary crushing at the mine site before being transported to the processing plant.

Sand and gravel typically are mined in a moist or wet condition by open pit excavation or by dredging. Open pit excavation is carried out with power shovels, draglines, front end loaders, and bucket wheel excavators. After mining, the materials are transported to the processing plant by suction pump, earth mover, barge, truck, belt conveyors, or other means.

The raw materials are first put into elementary-crushing machine (jaw crusher) via vibrating feeder for crush, and then the elementary products are transferred via the belt conveyor to the secondary-crushing machine (cone crusher) for secondary crush. The vibrating screen separates the secondary products into two kinds. The one satisfying the standard of the Vertical Shaft Impact Crusher (sand-making crusher) will be conveyed to the sand-making machine and become finished products after being washed by the sand washing machine. The other kind will return to the secondary-crushing machine to be crushed again.

When the input size of your materials is smaller than 40mm, we recommend you the sand making flow equipped with VSI5x series sand making machine, vibrating screen, sand washing machine, etc; otherwise, there is another solution designed for you, equipped with vibrating feeder, jaw crusher, impact crusher (optional), cone crusher, VSI5x series sand making machine, vibrating screen and sand washing machine.
