Cobble Sand Making Details

Cobble sand making process

Cobble materials are conveyed by vibrating feeder uniformly to a cobble crushing machine (such as jaw crusher) for primary crushing in order to break the largest stones down to a manageable size. The crushed cobble materials are then moved by belt conveyor to a further cobble crushing machine (such as impact crusher, cone crusher) to reduce the particle size down to smaller size. After each crushing process, the cobble particles are conveyed to vibrating screen for separation. Fine cobble particles of required size will moved to stockpile for sand washer to be cleaned, while large particles will return to cobble crushers for recrushing, which forms a closed-circuit process.
