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. If you are over feeding the chamber you will reduce the rotors ...

Restitution Modeling for Crush Analysis: Theory and Validation

The equations of crush analysis have traditionally neglected theΔV that occurs during the restitution phase, and thus, underestimate the velocity change that a vehicle experiences during an impact. Crush analysis theory has traditionally contained two parts. The first calculates the magnitude of crush energy absorbed by the vehicle structure.
