How Vertical Shaft Impact Crushers Work Mellott

How Vertical Shaft Impact Crushers Work. A VSI crusher works with both soft and hard materials.The material is then deflected from its original path, impacting other particles, and breaking them into smaller pieces. This process of repeated impact and reimpact results in a much finer product than traditional crushing methods, such as jaw A cone crusher and a vertical shaft impact (VSI) crusher were operated in closed circuit to compare the performance of the two different crushing machines. The crushers were operated in closed circuit with a 9 mm final screen aperture size. A comparison of capacity, size reduction and power draw shows that the VSI crusher is Energy considerations in compressive and impact crushing

Optimal energy control of a crushing process based on vertical shaft

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 crusher hopper, VSI used in both the simulations and the physical tests is a pilot-scale machine, model Barmac 3000 Duopactor, manufactured by TON Ò .

Understanding influence of crushers on shape

Moreover, both the methods showed consistent result, that the angularity of aggregates produced from CC is higher compared to VSI crusher. The inconsistency in angularity measurement and distribution, may be due to indirect nature of measurement and associated higher subjectivity in FAA test.Impact crushers produce high-quality end products efficiently. Impact crushers are named after the method they use in reducing larger blocks of rocks to smaller grain sizes. As the name suggests, an impact crusher accelerates the feed material to high speed and then flings the fast-moving rocks against the walls of the crushing chamber and eachImpact crushers high-quality impactors TON

The desired production volumes define the optimal size of the crusher. Rock-on-rock or anvil crushing, on the other hand, results in slightly different end products than normal tertiary and quaternary compression type crushing. NCM-FINE VSI crushers produce cubical aggregate that performs well in concrete, asphalt and base mixtures.The operating principle of the vertical shaft impact (VSI) crusher is shown in Fig. 2.Rock material falls down into the rotor which rotates so that the edge speed is about 50–60 m/s.The rock particles accelerate and impact the surrounding bed of rock that is formed during operation.Energy considerations in compressive and impact crushing
