The vertical shaft impact (VSI) crusher is a commonly-used machine in aggregate production. A comprehensive understanding of the physical phenomena that influence the power consumption and the particle output of the device are essential to enable development of protocols that minimize energy consumption during rock crushing.
mechanism used crushers are of three types namely Cone crusher, Jaw crusher and Impact crusher. Fracture occurs in the feed material when the strain developed in it due to sufficiently applied impact forces, pressure or shearing effect exceeds the elastic limit .Generally crushers are very rugged, massive and heavy in design.

Here the breakage can take place in a much shorter scale compared to fragmentation process used in cone or jaw crushers [7]. An impact crusher can be further classified as Horizontal impact crusher (HSI) and vertical shaft impact crusher (VSI) based on the type of arrangement of the impact rotor and shaft.

Jaw crushers reduce rock sizes between a fixed and moving jaw while cone crusher crush the rock between an external fixed element (bowl liner) and an internal moving element (mantle) [9,10].
Through a detailed methodology involving the determination of crushing force, selection of motor specifications, shaft design, and rigorous calculations, the following conclusions were drawn: 1) Crushing Force: The required crushing force for the sugarcane was determined to be 69 N based on empirical data and literature review.
While most crushers used in the primary and secondary stages of crushing work by having two surfaces compress particles between them, a vertical shaft impact (VSI) crusher instead relies on impact energy. By having the rock particles flung against each other at high rates of speed, the resulting impact creates a high
