VSI Crushing Method. The VSI is typically used after a primary or secondary crusher. This makes a VSI ideal for making sand and for making coarse and medium aggregates for concrete/asphalt production. Feed size and characteristics will affect the application of a VSI. The feed size is limited by the opening in the center of the rotor.
01-06-2021· The noticeable difference between fRCA and fine natural aggregate results from higher water absorption ... Ulsen et al. reported that different VSI crusher rotor speed had a significant effect on the water absorption of fRCA.

SCC – Visual Stability Index (VSI) Test – ASTM C1611. VSI = 0 – Concrete mass is homogenous and no evidence of bleeding VSI = 1 – Concrete shows slight bleeding, observed as a sheen on the surface VSI = 2 – Evidence of a mortar halo VSI = 3 – Concrete of coarse.
30-09-2017· The aggregates obtained from VSI crusher had maximum low angularity particles. Therefore, HSI produced aggregates had higher form 2D as compare to CC and VSI. Mean value of form 2D for different aggregate sizes is shown in Table 3. For all aggregate sizes, the HSI produced aggregates had highest form 2D and followed by CC and VSI.

In the interim, refer to the Authorised Inspection Scheme Business Rules: VSI 27 Mopeds and power-assisted pedal cycles: A guide to the differences between mopeds and power-assisted pedal cycles, and the respective registration and licensing requirements and rules.
VSI crushers are very flexible and their configuration can be changed to suit the application. Machines can be run in rock-on-rock, rock-on-steel and steel-on-steel configurations to suit different applications – and this can be altered throughout the machine's lifespan to accommodate changing needs. Compression crushing

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 along natural faults throughout the rock or ...
