摘要： A roll assembly temperature sensing system for a pellet mill includes: a thermal sensor (160); and a pellet mill roll assembly rotatably disposed in a rotor assembly. The pellet mill roll (140) assembly includes: a roll shaft; a bearing disposed circumferentially around the roll shaft; and a seal (150) disposed between an end of the bearing and the rotor assembly. The rotor assembly includes an area defining a die cavity adjacent to the seal (150). The thermal sensor (160) is disposed within the die cavity, and is configured to detect a temperature of the seal resulting from heat conducted from the bearing.

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 disperser-refiner plate segment comprising a refining section disposed radially outward from a dispersion section, wherein a height of the teeth in the dispersion section exceeds a height of the bars in the refining section. It is believed that disperser-refiner plate segments as described herein will allow operators to combine dispersion with refining and give operators greater control over the level of dispersion while minimally affecting the level of refining.

摘要： A flinger or refiner plate for a mechanical refiner including deep notches or holes in feeder bars of the flinger plate and/or open passages or holes in bars of the refiner plate. The open passages and/or holes in the bars significantly reduce stagnate flow zones at the trailing side of the bars during operation of the mechanical refiner. The reduction of the stagnate flow zones may reduce or eliminate fiber accumulation at the trailing side of the bars.

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.

摘要： A nozzle assembly with a self-cleaning face is provided, having a nozzle body with a liquid flow path defined therethrough with an inlet and a spray outlet. The nozzle body is mounted in a carrier body, and an annular gas flow channel is located about the nozzle body with a gas discharge outlet defined around the spray outlet. A porous surface is located about the annular gas flow channel at the gas discharge outlet. A radiused surface is formed in the carrier body at the air discharge outlet. A pathway is in communication with the porous surface and adapted to provide a low velocity fluid discharge from the porous surface. A spray device and method are also provided using the nozzle assembly with the self-cleaning face. An adaptor for retrofitting an existing nozzle is also provided.
