Stone processing mainly includes crushing and grinding. Both methods are used to reduce the size of or powder industrial rocks and minerals by crushers or grinding machines, which are called Stone processing machines and equipments. After processing, the stone or rock can apply in construction, building, highway and some chemical industries.
Crusher is to make bigger stone (30mm~1000mm) smaller (0mm~50mm); popular crushers have jaw crusher, impact crusher, VSI crusher (sand making machine) and so forth.
Grinding is the required powdering or pulverizing process when final size of below 2 mm is needed, grinding practice is a large and diverse area of manufacturing and tool making, grinding machines can produce very fine finishes (12~2500mesh/1.6mm~0.005mm), there are 6R grinder mill,High pressure suspension grinding mill,High pressure micro-powder mill,Raymond mill, etc.
Crusher can work separately or together with other equipments (likevibrating feeder, belt conveyor,vibrating screen etc.) to form a stone processing plant, the designed capacity can be from 30tph to 500tph (ton per hour), either fixed or mobile. To meet customer's specific requirement, other machines and equipments such as cone crusher, sand washing machine, dust catcher etc. can be added on the stone processing plant. While grinding machine usually work with other machines (small jaw crusher, bucket elevator, classifier, bag filter etc.) to form a grinding system.
