Tips to maximize impact crushing efficiency

2020-2-6 · 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 ...

Principle of impact crusher

11 Impact Crushers Types and Working Principle. In this class of crusher comminution is by impact rather than compression by sharp blows applied at high speed to free-falling rock. The moving parts are beaters which transfer some of their kinetic energy to the ore particles on contacting them. The internal stresses created in the particles are

2021-4-28 · Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "run - of - mine" ore, whi le grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition.
