Twister VSI crushers use two variations of VSI crushing. The first is vertical shaft impact crushing where rock is fed onto a table type rotor which accelerates and then discharges the rock at high speed against steel anvils in the crushing chamber. The impact of the rock against the steel anvils induces fracture and breaks the rock.

VSI Benefits. When it comes to producing materials such as aggregate for road making, VSI crushers use a high-speed rotor and anvils for impact crushing rather than compression force for the energy needed for size reduction. In a VSI, material is accelerated by centrifugal force by a rotor against the outer anvil ring, it then fractures and breaks …
There are two types of impact crushers: horizontal shaft impactor and vertical shaft impactor. Horizontal shaft impactor (HSI) / hammermill. The HSI crushers break rock by impacting the rock with hammers that are fixed upon the outer edge of a spinning rotor. HSI machines are sold in stationary, trailer mounted and crawler mounted configurations.
The rotor is set among mounted plates, anvils, or aprons, inside a heavy housing; these aprons or anvils serve to bear the impact of the materials being processed and further break them apart. There are two styles of impact crushers: horizontal shaft impactors (HSI) and vertical shaft impactors (VSI).

There are key differences between horizontal shaft impact (HSI) and vertical shaft impact (VSI) crushers, and understanding them will help you select the best impact rock crusher. How Impact Rock Crushers Work. Impact crushers use striking and high-speed impact forces to crush material. Instead of compression or grinding, the …
Vertical Shaft Impact Crusher . Abstract: In this paper, a new rotor with two impact in the vertical shaft impact crusher is analyzed, an effect of the angle at the guide device thrown materials on the velocity that material reach the impact plate and rebound to a anvil in the crushing chamber are discussed three mass ejection Angle are simulated by discrete …
Impact crushers reduce mineral materials such as concrete, asphalt and natural rock in size to produce a valuable commodity product. A fast spinning rotor throws the material against a solid stationary impact wall. The striking and impacting causes the material to shatter into smaller pieces. The result is a very homogenous and cubical product ...
This paper presents an optimal control model to improve the operation energy efficiency of a vertical shaft impact (VSI) crushing process. The optimal control model takes the energy cost as the performance index to be minimized by accounting for the time-of-use tariff and process constraints such as storage capacity of the VSI …

The Andersen/Awachie/Whiten model of the cone crusher has been applied in modeling the performance of a 264 kW vertical shaft impact crusher producing manufactured sand. The model has been supplemented by equations describing the variation of parameter K 3 in the classification function and the T 10 parameter of the …
The new Patented Tubular Rotor provides many benefits over the standard shoe and anvil designs as well as rock-shelf applications. The easily replaceable and indexable rotor tubes, cut your total operating cost and maintenance time in half, making V-Slam the easiest VSI crusher to maintain and one of the best impact crushers on the market.
Vertical shaft impact crushers. Vertical shaft impact crushers take the full advantage of so-called rock-on-rock crushing process. In vertical shaft impact crushers, the crushable material is fed through the centre of the rotor, where it is accelerated to high speed before being discharged through openings in the rotor periphery. The material ...
