Abstract: A self-aspirated froth flotation cell 100 may include a slurry vortex stabilizer 166 having an annular body 234 with an upper annular edge 176 and an aperture 180 extending through a central region of the annular body 234. The aperture 180 may have an inner surface 182 bounded between an upper inner edge 178 and a lower inner edge 200 that is configured to allow the drive shaft 142 to rotate freely therein in close proximity to the inner surface 182. The slurry vortex stabilizer 166 may have an annular undersurface 210 configured with a inner first portion 212, a second portion 236 provided around the first portion 212, and an annular intersection, transition, or inflection 214 therebetween. A sloped upper surface 242 which tapers downwardly towards the central region of the annular body 234 as it approaches the aperture 180 forms a lower fluid surface boundary within a standpipe 152 of the self-aspirated froth flotation cell 100.

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: The invention relates to a method for continuous, gravimetric metering and mass flow determination of flowable materials, comprising:
determining with a metering device an instantaneous mass flow at an anticipatory control point located a first distance ahead of a delivery point for the flowable material;
affecting discharge of the flowable material by altering a speed of rotation of the metering device and
varying the first distance of the anticipatory control point ahead of the delivery point depending on at least one of a current actual speed and a loading of the metering device, wherein the loading of the metering device is calculated on the basis of a sectoral load measurement.-

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: 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.
