When subjected to high-speed impact such as v m = 25 or 50 m/s, impact performance in terms of crushing force efficiency and cushion factor benefits from the increase of r/R. Although increasing r/R from 0.04 to 0.2 can dramatically decrease Poisson’s ratio from 0.07 to − 0.63, structural Poisson’s ratio is still highly controlled by the crushing velocity.

Impact crushers and cone crushers tend to be used during these stages to better control particle size and shape. Understanding how to best match the type of crusher to the right crushing stage, as well as working with a manufacturer to properly size the crusher, will ensure crushing and feeding efficiency throughout an operation and, ultimately, overall profitability.

the crush is not as easily quantified and various difficulties arise as to exactly what crush value to use. A careful review of the derivation of the model reveals that the use of the crush at separation of the collision partners is required. The crush at separation is easily determined from a derived force deflection chart as seen in Figure 5.
