Abstract
The invention relates to a cone crusher (1) for comminuting lumpy feed material (material to be crushed), with a crushing cone (6) supported on an axial bearing, inclined to the axis of rotation (R) and driven by an eccentric bushing (12), wherein the eccentric bushing (12) rotates in radial guidance around a fixed axle journal (10). The invention is characterized in that a central axis (Z) of the crushing cone (6) is aligned skewed to the axis of rotation (R) of the eccentric bushing (12). The invention further relates to an eccentric bushing (12) and a method.
Claims15
Cone crusher (1) for comminuting lumpy feed material (material to be crushed), with
- a crushing cone (6) supported on an axial bearing, inclined to the axis of rotation (R) and driven by an eccentric bushing (12), wherein the eccentric bushing (12) rotates in radial guidance around a fixed axle journal (10),
- characterized in that a central axis (Z) of the crushing cone (6) is aligned skewed to the axis of rotation (R) of the eccentric bushing (12).
Cone crusher according to any one of the preceding claims, wherein a phase shift (DP) between a lower closed gap (GSS-U) and an upper closed gap (GSS-O) is at most 180°, preferably at most 90°.
Cone crusher according to any one of the preceding claims, comprising a head eccentric bushing which is axially spaced from the eccentric bushing (12) along the axis of rotation (R) and radially guides the crushing cone (6) on the axle journal (10) in the region of a minimum distance between the axis of rotation (R) and the central axis (Z). of the crushing cone (6).
Cone crusher according to any one of the preceding claims, comprising a balancing weight which is arranged with its center of mass out of phase with the deflection plane of the central axis (Z) of the crushing cone.
Cone crusher according to any one of the preceding claims, wherein the central axis (Z) of the crushing cone (6) is aligned with the axis of rotation (R) of the eccentric bushing (12) in such a way that in an upper region of the crushing chamber (4) a relative stroke of at least 3%, preferably at least 5% can be carried out.
Cone crusher according to any one of the preceding claims, wherein the crushing cone (6) is floatingly mounted.
Cone crusher according to any one of the preceding claims, comprising a head support (22) for the crushing cone (6), wherein the crushing cone (6) is freely rotating but eccentrically mounted on the head support.
Eccentric bushing (12) for use with a cone crusher (1) according to any one of the preceding claims.
