Case StudyA Crushing Plant invested by Chinese Government aims to crush Granite Stones for road construction. The detailed requirements are as following:
Raw material: GraniteFeeding Size: 800mm Output size: 0-5mm, 5-20mm, 20-40mmProcuction ProcessThe raw materials are unloaded by trucks into the hopper. By vibrating feeder, raw materials are regularly fed into Primary Jaw Crusher which could reduce 800mm stones into approx.150mm. The half-finished products from Jaw Crusher will be conveyed by Belt Conveyor. #1 and piled up into the transmediate storage hopper. Another small Feeder under the stockpile will feed the stored materials regularly into Belt Conveyor #2 so as to transport the material to the following Cone Crusher S51''. After secondary crushing, products will be conveyed bt Belt Conveyor #3 & #5 to the Vibrating Screens for size separation: 0-5mm, 5-20mm, 20-40mm and +40mm. The unrequested products which are bigger than 40mm will be returned to the tertiary Cone Crusher S36'' by Belt Conveyor #4 for further crushing, while products with requested size will be piled up by Belt Conveyor #6. Natural fines from the grizzly bar of the vibrating feeder are conveyed by Belt Conveyor #7 as separate stone scrap.Flow Chart for This Crushing Plant
