Abstract: The disclosure relates to novel components of a gyratory crusher (1) which aim to promote self-alignment of a mainshaft assembly (2) upon introduction of the mainshaft assembly (2) into the gyratory crusher (1) by lowering the mainshaft assembly (2) from above the gyratory crusher (1) into the gyratory crusher (1). The novel components may include a dust bonnet (9) having a plurality of guides (15), an end plate (32) having a lower alignment chamfer (36), and/or a counterweight (13) having an alignment chamfer (41). Each of the novel components may be configured to bias a lower mainshaft (26) of the mainshaft assembly (2) of the gyratory crusher (1) into concentric alignment with a bore (56) of the eccentric (11) or eccentric liner (12).

Abstract: A lifting apparatus (100) for hoisting a spider (200) of a gyratory crusher has a spreader (110) spanning between two leg members (120) each having an offset arm (121a), clearing arm (121b), cradle arm (121c), and securing arm (121d). The offset arm (121a) forms a second offset distance (131) with respect to an offset axis (C). The arms (121a-121d) form an opening (123) for receiving the spider (200). The leg members (120) oppose each other such that the clearing arms (121b) of the leg members (120) are provided on opposite sides of a plane defined by the horizontal axis (D) and vertical axis (A). The lifting apparatus (100) may be lowered over the spider (200), and rotated approximately 90 degrees in a direction (B) of rotation about the vertical axis (A) to cradle and support the spider (200) from below the spider (200).

Abstract: An internal inclined sub-channel, or ramp device, for suspending and/or re-suspending solids within a pipeline system during transport of slurry may be provided to various components of the slurry transport system to control or reduce localized and severe wear that often occurs in slurry pumps. Embodiments of the ramp device may be adequately configured to alter slurry multiphase flow patterns and/or disrupt traditional moving/sliding bed regime phenomena. Embodiments of the ramp device may be adequately configured to raise coarse abrasive particulates from bottom portions of a slurry pipe section—where a higher concentration and/or a larger presence of coarser particles may be present. Embodiments of the ramp device may be installed in proximity of and/or upstream of slurry pumps to prevent occurrences of severe localized wear at the inner diameter of the pump suction side wall around the bottom or 6 o'clock position.

Abstract: Provided are non-limiting embodiments of a wear-resistant impeller having a non-conventional blending provided between a surface of a vane (1) and a surface of at least one of a front side shroud (15) and a rear side shroud (16). The impeller may comprise both a rear side blending (3) and a front side blending (2), and the front side blending (2) may comprise a different geometry from the rear side blending (3). The blending preferably comprises a bulbous geometry which is uniquely adapted for optimizing flow patterns adjacent to the vane and between the front and rear side shrouds in a manner which discourages the formation of horseshoe vortices proximate the leading edge (6) of the vane (1) during operation. Through the reduction, mitigation, or elimination of horseshoe vortices, local high velocities and turbulence are generally minimized, and wear experienced by portions of the impeller (e.g., to one or more vanes) from flows of abrasive slurry can be reduced. Accordingly, the useable life of an impeller may be improved.
