ABSTRACT:
An improved centrifugal impactor for crushing rocks includes a hollow housing having a peripheral crushing chamber and a rotor mounted in the housing for rotation relative thereto about a generally vertical axis and spaced radially inwardly from the crushing chamber so as to define an annular passage for communicating a flow of rocks from an upper inlet opening and the crushing chamber to a lower outlet opening. The rotor includes a horizontal platform and a pair of outer and inner annular vertical barrier members attached to and extending upwardly from the horizontal platform. The outer barrier member is disposed about a peripheral edge of the horizontal platform. The inner barrier member is disposed in concentric relation with the outer barrier member and spaced radially inwardly from the outer barrier member and outwardly from the vertical rotational axis of the rotor and extends a shorter distance above the horizontal platform than does the outer barrier member such that the outer and inner barrier members of the rotor cooperate to trap and accumulate rocks and form a pair of separate concentric annular beds of accumulated rocks in a substantially symmetrical distribution on the horizontal platform of the rotor which rotate with the rotor and produce an improved internal balance of a rotor and a substantially uniform centrifugal discharge of rocks from the rotor over the inner and outer walls thereof.
