ABSTRACT:
An impact crusher has a housing; a rotor mounted in the housing for rotation in a predetermined direction about a substantially horizontal axis; a charging opening in the housing above the rotor and at one side of the axis at which the rotation of the rotor is in upward direction; impact plate arrangement at the other side of the axis at which the rotation of the rotor is in downward direction so that material admitted through the opening and falling onto the rotor is flung against the plate arrangement, the plate arrangement comprising a first impact plate at a level higher than the rotor and a second plate spaced from the first plate in the predetermined direction, each plate having an impact surface facing generally opposite to said direction; and arrangement for displacing said first plate to and from a position in which the impact surface of the first plate is proximal to and constitutes an extension of the first impact surface of the second plate.
