Abstract: Disclosed, is a drive (101) for a sedimentation tank (1000) comprising a main ring gear (160) operatively connected to a cage (150) via a web portion (152). A bearing transfer ring (170) is provided to the web portion (152) such that a gap (172) is provided between the bearing transfer ring (170) and the main ring gear (160). The bearing transfer ring (170) is connected to a first bearing race (144) which communicates with a second bearing race (142) that is fastened to a base portion (136) of the drive (101). Torque (T) is delivered to the cage (150) to turn a rake assembly (1002). The gap (172) provides clearance for deflections, distortions, or deformations of the main ring gear (160) caused by bending stresses (B) in the main ring gear (160) may. The bearing transfer ring (170) absorbs stresses imparted to the main ring gear (160) and prevents fasteners (188) connected to stiff bearing races (144) from shearing. Also disclosed is a retrofit kit for a sedimentation tank drive, a sedimentation tank (1000) having a drive (101) according to the above description, and a method of thickening/clarifying slurry (1008) utilizing a drive (101) according to the above description.

Abstract: A roller for use in devices configured to comminute material has a wear surface. The wear surface comprises inserts that are spaced apart differently to provide a desired wear characteristic in the wear surface. In one embodiment, some inserts may also have diameters or widths that are smaller than other inserts. For example, columns of inserts adjacent an end of the roller may have diameters that are smaller or larger than inserts in columns located near the center of the roller or otherwise positioned between the two ends of the roller. As another example, a middle portion of the wear surface may have inserts that include inserts of a larger or smaller diameter than inserts adjacent the ends of the wear surface.

Abstract: A roller press having an improved edge wear assembly is disclosed. The roller press comprises a roller [200] having an axis [203]. The roller [200] comprises an outer surface [205] containing one or more wear inserts [280] and an annular abutment surface [207] proximate an end of the outer surface [205]. The annular abutment surface [207] extends generally transversely with respect to the outer surface [205] of the roller [200]. A plurality of wear components [211] extend from the abutment surface [207] in a direction generally parallel to the axis [203] of the roller [200], wherein at least two of the wear components [211] are circumferentially interlocked with one another so as to resist axial and/or radial pull-off forces as material flows between other wear inserts [280] located on the roller [200]. Fasteners [230] are received by receiving portions [215] in and secure the wear components [211] to the abutment surface [207] of the roller [200].

Abstract: An energy diffusion sealing ring [872] for use with a hydrocyclone or pump is provided. The energy diffusion sealing ring [872] comprises a sacrificial suspension matrix [872A] comprised of a polymer, elastomer, or combination thereof, and a number of packed inserts [872B] suspended in the matrix [872]. The matrix [872] serves as delivery means for the inserts [872B] into one or more recessed portions [833, 841]. The inserts [872B] comprise a hard material (e.g., ceramic or carbide) and form wear bodies which slow and dissipate kinetic energy of escaping slurry by way of creating paths of resistance. As the suspension matrix [872A] erodes over time, a plurality of interstices [872C] between the inserts [872B] are formed. Escaping slurry [852] slows as it traverses three-dimensional serpentine paths defined by said interstices [872C], thereby reducing its potential to wear surrounding components. Methods for manufacturing an energy diffusion sealing ring [872] and for dissipating the energy of slurry [850] are also disclosed.

Abstract: A centrifugal pump for a slurry combines design changes with respect to conventional configurations that produce quasi-laminar flow and materially extend the life of the casing. The cutwater clearance of the casing is increased to a range of 0.20 to 0.25 times the diameter of the impeller. The casing includes a redesigned removable annular liner with a diameter increased to at least 1.15 times the diameter of the impeller. The pump preferably also has an axially adjustable wear ring with a diameter increased such that it extends by at least 10% over the diameter of the area of interface between the wear ring and the impeller.

Abstract: Disclosed is a method for calcining a natural chalk powder within a rotary kiln. The powder is inserted into the kiln accompanied by an additive that promotes nodulization of the powder to thereby facilitate the treatment of the chalk powder within the rotary kiln. The nodulization takes place at temperatures less than the calcining temperatures of the chalk and prior to the nodulized chalk being calcined within the kiln.
