IMPACT CRUSHING Impact crushers may be used as primary, secondary, or tertiary crushers. Despite having a somewhat higher operating cost than other crushers, they tend to produce a more uniform particle shape. Impact crushers usually will benefit the aggregate better than compression crushers, and they may generate more fines.
Starting from the base working principle that compression is the forcing of two surfaces towards one another to crush the material caught between them. Impact crushing can be of two variations: gravity and dynamic. An example of gravity impact would be dropping a rock onto a steel plate (similar to what goes on into an Autogenous Mill). Dynamic impact could be described as material dropping ...

PERFORMANCE MODEL FOR IMPACT CRUSHER General scheme of breakage process Impact breakage takes place in a very small time scale and results into a dynamic crack propagation that leads to a much faster failure of particles. The impact generates compressive and tensile shock waves that travel throughout the particle.

Dec 10, 2004· Impact breakage takes place at a much shorter time scale compared to the fragmentation process used in cone or jaw crushers. Hence, the nature and magnitude of forces as well as the energy transfer and dissipation related to impact breakage are very different from the relatively slow breakage by compression and shear used in other types of ...
DEM-Simulation of the Breakage Process in an Impact Crusher Abstract The process area of an impact crusher was modelled using the Discrete Element . The DEM model was developed using the Particle Flow Code PFC from Itasca 5 which . These values formed our reference data for the calibration process i.e. the .
The impact device more nearly approaches actual crusher operation, both in velocity of impact and in the fact that broken stone is used in testing. The average impact crushing strength is an indication of the energy required for crushing, while the maximum compression values indicate the danger of crusher breakage and the type of construction ...
