VSI high-efficiency vertical shaft impact crusher, commonly known as sand making machine and shaping machine, is the fourth generation high-performance sand making machine with world-class level, which is the new development equipment result of SBM's introduction of German authoritative experts.
With two feeding modes, the whole center feeds:
the material falls into the feeding hopper, and after entering the high-speed rotating rotor through the center feeding hole, it is fully accelerated and thrown through the launching port, firstly with a part of the material that falls freely after rebounding. Impact, and then impact together on the vortex lining (or counter-block) in the surrounding vortex chamber, first rebounded to the top of the crushing chamber, and then deflected downward to form a collision with the material emitted from the impeller runner. The continuous material curtain is discharged through the lower discharge opening.
The center feed is accompanied by an annular waterfall feed:
The material falls into the feed hopper and falls through the annular hole, and is divided into two by the bulk disk. One through the distributor plate enters the high-speed rotating impeller, and the other one falls from the periphery of the distributor tray, and the material entering the impeller is rapidly accelerated in the impeller and then thrown at a high speed, firstly with another part of the free-falling body around the bulk disk. The material impacts and breaks, and then impacts together on the vortex lining (or counter-block) in the surrounding vortex chamber, first rebounded to the top of the crushing chamber, and then deflected downward to move with the material emitted from the impeller runner. The impact forms a continuous curtain of material and is discharged through the lower discharge opening.
The product is cubic, with good grain shape, reasonable gradation and adjustable fineness modulus. It is especially suitable for artificial sand making and stone shaping.
The equipment is light in weight, various in installation methods, and easy to operate. Once the specific application is clear, it can be used to a very large extent to achieve its excellent performance.
