Vertical shaft impact crusher, feeding chamber side wall and method for replacing a worn feed tube

摘要

A vertical shaft impact crusher comprises a rotor (1), adapted for rotating about a substantially vertical axis for accelerating a flow of material to be crushed; a housing, comprising a circumferential impact wall section against which the accelerated flow of material may be crushed; a feed tube (46), adapted for vertically feeding a flow of material to be crushed into the rotor (1); and a feeding chamber (21), defined by a feeding chamber side wall (22) and adapted for vertically feeding a flow of material into the feed tube (46). A first door (56) is provided for opening and closing an aperture (54) in the feeding chamber side wall (22), such that said feed tube (46) may be removed from said feeding chamber (21) via said first aperture (54).
