A vertical shaft impact crusher includes a rotor that rotates about a substantially vertical axis for accelerating a flow of material to be crushed. The crusher further includes a housing, a feed tube, and a feeding chamber. The housing includes a circumferential impact wall section against which the accelerated flow of material may be crushed. The feed tube is for vertically feeding a flow of material into the rotor to be crushed. The feeding chamber includes a feeding chamber side wall and is for vertically feeding a flow of material into the feed tube. A first door is provided for opening and closing an aperture in the feeding chamber side wall. The feed tube is removable from the feeding chamber via the first aperture.
