Embodiment Construction

[0037] Figure 1-3 A rotor 1 of a vertical shaft impact (VSI) crusher is shown. The rotor 1 has a top plate in the form of an upper disk 2 and a bottom plate in the form of a lower disk 3 . The lower disc 3 has a hub 4 which is welded to the lower disc 3 . The hub 4 is connected to a shaft (not shown) for rotating the rotor 1 within the housing of the VSI crusher.

[0038] The upper disk 2 has a central opening 5 through which a first stream of material to be crushed can be fed into the rotor 1 .

[0039] The upper disk 2 and the lower disk 3 are separated and held together by a vertical rotor wall which is divided into three wall sections 6 . The gaps between the wall parts 6 define outflow openings 7 through which material can be thrown towards the housing wall.

[0040] During operation of the rotor 1 a bed 8 of material accumulates inside the rotor 1 against each of the three wall portions 6 . exist image 3 Only a single bed 8 of material is shown in .

Abstract

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.

Description

technical field [0001] The present invention relates to a vertical shaft impact crusher comprising: a rotor adapted to rotate about a substantially vertical axis to accelerate the flow of material to be crushed; a housing comprising a circumferential impact wall portion through which the accelerated material A flow can be crushed against said circumferential impact wall portion; a feed pipe adapted to vertically feed the flow of material to be crushed into the rotor; and a feed chamber consisting of The feed chamber sidewalls define and are adapted to vertically feed a flow of material into the feed tube. [0002] The invention also relates to the side walls of the feed chamber and to a method of replacing a worn feed tube of a vertical shaft impact crusher. Background technique [0003] Vertical shaft impact crushers (VSI crushers) are used in many applications for crushing hard materials such as rocks, ores, etc. WO 2004 / 020103 describes a VSI crusher comprising a housin...
