<p>Impact crusher, especially for crushing stone, the housing of which comprises a delivery chute for supplying the material to be crushed to a rotor which has beater blades , rotates about a horizontal axis and with which rebound walls are associated, which rebound walls approach the rotor in the region of the upper quadrant of the descending side of the rotor and form, with the latter, a delivery opening for the crushed material. One or more slipways project in the region of the delivery opening from the rebound wall towards the rotor and form, with their upper edge, a guideway which extends from the delivery-opening at a slight angle towards the horizontal and is guided upwards in a direction over the rotor .</p> |
