    摘要： A trunnion roller thrust measurement assembly includes a trunnion roller assembly and a thrust measurement assembly. The trunnion roller assembly includes a roller configured to provide rotary support of a rotary drum; a shaft attached to the roller, the shaft being aligned with an axis of rotation of the roller; and a bearing housing configured support an end of the shaft. The thrust measurement assembly includes a bearing housing end cap attachable to an end of the bearing housing; and one or more thrust sensors disposed on the bearing housing end cap. The one or more thrust sensors are configured to sense a thrust force exerted on the bearing housing end cap by an axial displacement of the shaft. An adjustment mechanism is utilized to skew the roller based on the sensed thrust force.

    摘要： A plate segment includes a substrate having a front side and a back side, wherein the back side is configured to be mounted to a support disc of a disperser; rows of teeth protruding from the front side of the substrate, wherein each of the rows are arranged along an arc extending from one side of the plate segment to an opposite side of the plate segment. In at least one of the rows of teeth, adjacent teeth are joined by a bridge spanning a gap between the adjacent teeth. The bridge is elevated above the front side of the substrate such that the bridge is separated from the front side by an open space in the gap.

    摘要： A feedwell design for a clarifier that may better dissipate the entrance energy of feed slurry liquid exiting the feedwell and entering the clarifier. Plates having a surface area twisted around a longitudinal axis may be provided at the bottom of the feedwell. The plates may cause a change in the flow direction of the feed, from being mostly horizontal to mostly vertical, to slow the slurry. The provision of plates at the bottom of a feedwell in a clarifier may advantageously reduce the velocity of the materials entering the clarifier, or may increase the uniformity of the flow rate of the materials while reducing or maintaining the amount of shear force, turbulence, or other forces that may have a detrimental effect on clarification. Likewise, this may improve the rate at which solids settle out of the feed slurry solution, and thus improve the clarity of the removed liquid.

    摘要： A refining system and process using a specially designed stator refiner plate. The specially designed stator refiner plate includes a major refining surface having a series of bars and grooves, the bars include a leading surface having an irregular surface. The irregular surface hosts a series of protrusions extending along the bar. The bar further comprises a trailing surface that is relatively smooth compared to the leading surface. The trailing surface lacks an irregular surface.
