Vertical Shaft Impact Crusher

Vertical shaft impact crusher vertical shaft impact crusher is also called vsi crusher.This crushing machine is a kind of highly efficient rock crushing plant at domestic and international advanced level researched and developed by shanghai shibang machinery co., ltd.By introducing the famous crusher principle and technology of "stone against stone" from america barmac company in accordance with the actual conditions of sand production at home.Features / advantages: 1.Simple structure ,low cost 2.High efficiency and low consumption 3.Primary and second crushing capacity 4.More naf most hard materials can be crushed 5.Cubic shaped fina product 6.Little noise and dust pollution 7.Conveniengt performance ,maintenance,installation vertical shaft impact crusher application vsi crusher is widely used for medium and fine crushing (sand making) for various hard and brittle materials such as rocks, grinding materials, refractory materials, cement clinker, quartz, iron ore and concrete aggregate, etc.It is especially appropriate for sandstone for architecture and road construction.Vertical shaft impact crusher structure & wear parts vsi crusher is made up of first stage impact curtain with anvils, impact crutain adjusting rods, second stage impact curtain with anvils, rotor, liner plate, blow bar, wedge lock assembly, discharge opening, third stage impact plate, back-up bar and so on.Working principle of vertical shaft impact crusher the whole pcl certical impact crusher including feed hopper, classifier, whirl pool cacity, impeller, main bearing assembly base, transmission device and motor etc.Operating pinciple is as follows: the materials enter the crusher through feeder hopper, which is divided into two parts, one part through the middle of classifier entering into the rotating impeller at high speed, then accelerated, whose speed can reach hundreds of acceleration, then is shot through the tunnels around the impeller by the speed of 60-75 meter/second.First the materials will impact with some materials fallen around classifier, then impact on the whirlpool cavity's scaleboard together, then will be rebounded and impact on the top of the whirlpool cavity, then changs its direction and goes down, forms continual material layers with the materials shot from the impeller.Therefore some materials will be impacted, crusher, milled twice or more times in the whirlpool cavity, then crushed matetials will be excluded through the bottom discharginghole.This can from a closed circulation through the circular classifier system; in general, materials can be crushed into 20 mesh through thrice circulation.Airflow self-circulation in the whirlpool cavity can eliminate the dust pollution well.
