Large stones from the silo through the vibrating feeder are evenly sent to jaw crusher for primary crushing. Then, the discharged material will be transported by the belt conveyor to the impact crusher for further crushing; After the crushing in the impact crusher, the material flows to vibrating screen for screening. During the screening, the material whose size meet requirement will flow into the stockpile. While the ones wwhose size don't meet the requirement will return to the impact crusher for rebreaking. Just like this, there is a closed circuit. By the way, Finished size can be combined afresh according to the needs of users. Working Principle: PFW Hydraulic impact crusher improves the adjusting device, the operation becomes more convenient. The tri – cavity makes excellent capability in the fine crushing and super fine crushing Plant. The bi-cavity can simplify the process flow in the coarse crushing Plant. The JOYAL Impact Crusher is used for primary, secondary and fine crushing of all kinds of stones and rocks with compressive strength less than 350 MPa such as granite, marble, and limestone. The Impact Crusher is widely used for sand and rock production in the industry of roads, railways, reservoir, electricity power, building materials and so on.
The working principle of Impact Crusher: When the impact crusher works, the motor drives the rotor rotate with high speed, on the rotor where installed the hammers. When the materials get into the area which the hammers effect, under the impact function of the hammer at a high speed, the materials are thrown to the impact device above the rotor continuously. And then the materials are rebounded from the impact liner to the area where the hammers effects for being crushed again. The materials from large to small all to be crushed at the impact chamber repeatedly. The process won’t stop till the material are crushed to the required size and then discharged from outlet. Features of Vertical Impact Crusher: Excellent performance and high final fineness; Safe and user-friendly; Smooth and quiet operation; Minimum maintenance; Heavy duty design; Long service life; Standard replacement parts; Cost effective; Cubically shaped product; High productivity.
