Tips to maximize impact crushing efficiency

Impact crushers do not run on the choke fed theory. Jaws and cones need to be choke fed as they work on gravity and compression. Where as impact crushers work on actual impact force (inertia) from the rotor blow bars that impacts the rock sends it at speed into the impact aprons.

A performance model for impact crushers ScienceDirect

2002-10-1  For comparison, when the model of Whiten and White (1979) is used for simulation of the behaviour of short-head cone crushers, the values for φ, m and l are often fixed to 0.2, 0.5 and 2.5 respectively. A greater value for the fine fraction φ in our case reflects the well-known fact that the product issued from impact crushing contains more fines than that obtained with cone or jaw crushers.
