Embodiment Construction

[0019] figure 1 A gyratory crusher 1 with a crushing cone 10 and a crusher housing 11 is shown in a cross-sectional view, wherein the drive, the cone mounting and other parts of the undercarriage of the gyratory crusher 1 are not shown for reasons of clarity part.

[0020] The crusher housing 11 together with the crushing cone 10 forms an encircling crushing space 12 which is open towards the top with respect to the crushing throat 13 at a feed angle α in a radial plane. In the lower region, the crushing cone 10 together with the crusher housing 11 forms an annular crushing gap 14 such that the crushing space 12 tapers downwards into the crushing gap 14 . The crushing cone 10 is arranged in a convoluted rotational movement by means of an eccentric (not shown), so that the crushing gap 14 increases and decreases periodically in a revolving manner.

[0021] If the quarry material is crushed by periodically increasing and decreasing the clear width surrounding the crushing spac...

Abstract

The invention relates to a gyratory crusher (1) for breaking up crushing material, comprising a crushing cone (10) and a crusher housing (11), wherein a circumferential crushing chamber (12) extends between the crushing cone (10) and the crusher housing (11), and wherein the crushing chamber (12) ends in a crushing mouth (13) open at the top, via which the crushing material can be introduced into the crushing chamber (12), and wherein the crushing chamber (12) is tapered downward into a crushing gap (14), through which the crushed crushing material can exit the crushing chamber (12). According to the invention, the crushing wall surface (15a) of the crusher housing (11), which crushing wall surface faces inward toward the crushing cone (10) and bounds the crushing chamber (12), has a waveform (16) in the upper region, which waveform begins at the crushing mouth (13), wherein the waves of the waveform (16) form wave troughs (16a) and wave peaks (16b) alternately in the circumferential direction.

Description

technical field [0001] The invention relates to a gyratory crusher for crushing quarry material, the gyratory crusher having a crushing cone and a crusher housing, wherein a circumferential crushing space extends between the crushing cone and the crusher housing , and wherein the crushing space opens into a crushing throat open towards the top, through which quarry material can be fed into the crushing space, and wherein the crushing space tapers downwards into a crushing gap, via Crushed quarry material can exit the crushing space via the crushing gap. Background technique [0002] A gyratory crusher for crushing quarry material is known from DE 1 107 052 ​​A, which has a crushing cone arranged almost in the center of the crusher housing and which is configured is basically rotationally symmetric. The crushing cone is driven eccentrically while undergoing a slight self-rotation, so that the crushing space formed around the crushing cone is subjected to a rotational contra...
