Abstract
A vertical shaft impact crusher including a housing, a vertical rotating shaft (11) rotatably provided in the housing and rotated at a high speed, a rotor (10) provided on the upper end of the vertical rotating shaft (11) to discharge centrifugally an object of crushing, which is cast into the housing, to the outer periphery thereof, and an anvil support frame (60) disposed in the housing to surround the outer periphery of the rotor (10) and provided with anvils (18) for collision with the object of crushing discharged from the rotor (10). The anvil support frame (60) is movable up and down in a direction parallel to the central axis of the vertical rotating shaft (11). The vertical shaft impact crusher further includes support means (71) disposed in the housing for supporting the lower end of the anvil support frame (60), vertically moving means (72) disposed in the housing for vertically moving the anvil support frame (60) in the direction of the central axis, and heightwise position adjusting means (73) disposed on the support means (71) for adjusting the heightwise position of the anvils (18) when the anvil support frame (60) is moved up by the vertically moving means (72), thereby reducing the frequency of replacement of the anvils, and thus facilitating maintenance.
