Barmac® vertical shaft impact (VSI) crushers were the first vertical shaft impactors in the world. The original Barmac® VSI crusher was developed in New Zealand over 40 years ago after which the VSI crushers have spread to thousands of crushing sites around the globe.
· 2.3.2. Vertical shaft crushers. In vertical shaft crushers, the particles are projected towards the crusher walls by the centrifugal forces from a rotor in the form of a turning table with radially oriented guides (Fig. 2, right). Unlike the horizontal shaft crushers, here the fragmentation takes place mostly at the internal walls of the .
vertical shaft impact crusher Vertical Shaft Impact (VSI) crushers are designed to be used in secondary, tertiary or quaternary stage crushing. The crushers are suitable for a wide range of applications including the production of high quality manufactured sand, well formed aggregates and industrial minerals.
VERTICAL SHAFT IMPACT CRUSHERS (VSI) CV200 RANGE VSI CRUSHER The rotor, being the heart of the crusher, is designed for high capacity with a low power consumption. It is vitally important that the correct size of crusher is selected for the required application. Be aware that when
Vertical shaft impact crushing (VSI) Rock-on-steel impact: rock is fed onto a table-type rotor which accelerates at high speeds in order to fling the rock against the steel anvils located in the crushing chamber; therefore, fracturing the rocks as they impact against the steel. Vertical shaft autogenous crushing (VSA) Rock-on-rock impact: rock
vertical shaft crusher bearing rotor. Rotor balancing bearing adpater sleeve only balance shaft bearing rest side plate joining plates first assemble the rotor balancing machine ensure the bearings are not damaged or dirty clean off any dirt or old oil, and if they sound or feel too worn, we recommend the bearings be changed after they are clean, add a little oil
US4896838ARotor for vertical shaft impact crushers . A rotor for a vertical shaft impact crusher features a unique protector for the trailing edge of each material exit portal of the crusher. The portal protector includes upper and lower "wings" between which is a channel.
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. The second variation is called vertical shaft autogenous
Common types of Impact Crushers are Horizontal Shaft Impactor (HSI) and Vertical Shaft Impactor (VSI). While the ultimate design of each type of impactor is to crush rock, their methodologies differ. Horizontal Shaft Impactors (HSI) consist of a hopper, two or three aprons (curtains), a rotor, and hammers (blow bars).
Vertical Shaft Impactors consist of a feed hopper, a feed tube, a rotor, and either stationary anvils or rock shelves. Essentially, feed material drops through the feed tube into the rotor, which, through centrifugal force, throws the material against stationary anvils made up of composite metal alloys or rocks (through the installation of a

Vertical shaft autogenous crushing (VSA) Rock-on-rock impact: rock
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
YV series vertical shaft impactors (VSI) are used as a second and third crushing stages for hard and abbrassive materials such as basalt and river gravel. While some of the material fed to the crusher entering the rotor, the remaining flow from the windows and is poured around the rotor, the part which entered the rotor is thrown out by the
The single rotor primary impact crusher of the HPI series is used in the cement industry with grinding path, for the production of a raw material with an ideal grain size distribution for further grinding in vertical roller mills. Equipment The rotor can handle feed material up to 3 m³. The HPI crusher has two impact aprons and can
Vertical-shaft impact (VSI) crushers Generally recognized as tertiary crushers, vertical-shaft impact crushers have material fed into the centre of the crusher, through a feed tube, and on to the centre of a rotating table or rotor. The material is then accelerated to

Weir Minerals’ expertly designed impact crushers generate excellent particle shape and are the ideal tool when manufacturing end products such as asphalt, concrete or manufactured sand. We offer both Horizontal Shaft Impactors (HSI) and Vertical Shaft Impactors (VSI) to suit your application needs.
The New Holland-style crushers are also known as Primary Impact Breakers. These crushers are known to take huge feed sizes and generate cubical products at better than 20:1 reduction. Its free-flow design combines a large expansion crushing chamber; a large, solid, fabricated rotor; upper deflector screen gate with vertical opening; and lower
Vertical Shaft Impactors consist of a feed hopper, a feed tube, a rotor, and either stationary anvils or rock shelves. Essentially, feed material drops through the feed tube into the rotor, which, through centrifugal force, throws the material against stationary anvils made up of composite metal alloys or rocks (through the installation of a
Apr 27, 2016· All roads, you might say, lead to the vertical shaft impactor (VSI) because these crushers make it possible to create roadways and just about everything else. Francis E. Agnew of California patented one of the first VSIs in 1927. His configuration stacked three of them on top of each other to produce sand, thus beginning the evolution of the VSI.
The Geometrical Model of Vertical Shaft Impact Crusher Rotor System . By Zhang Junming. Counter rotating subsystem figure condition check, the 3D model is proved to be correct, for the next dynamic modeling of the model combined with removal and the basis for dynamic simulation. Solid Works Software Solid Works is a company specializing in
VSI (Vertical Shaft Impactor) Cone crusher is a primary crusher, used in mining or Ore processing. It reduces large aggregates to smaller aggregate. VSI means, 'Vertical Shaft Impactor'. In which shaft and crushing chamber are in a vertical position which is a latest crushing technology.
It has a high speed rotor with wearing resistant tips and main chamber (crushing chamber) is designed in such a way so that speed rotor throw the rocks against the high crushing chamber. In vertical shaft impactor crusher predominant force is the velocity of speed rotor. Shree Conmix Engineers Pvt. Ltd.  is a famous for Vertical Shaft
