A diversion assembly for use with a feed material. The diversion assembly includes a plurality of movable gate chutes, a first conveyor, and a second conveyor. The plurality of movable gate chutes are each positionable in a retracted position and an extended position. The first conveyor is configured to carry, for each of any of the plurality of movable gate chutes in the retracted position, a first portion of the feed material to a first area. The second conveyor is configured to carry, for each of any of the plurality of movable gate chutes in the extended position, a second portion of the feed material to a second area. The second area is spaced apart from the first area.

The invention relates to a screw (1) for an extruder or conveyor (20), in particular extruder screw, conveying screw or dosing screw for polymers, having a web (3) running helically around a core (2), wherein the web (3) is formed undercut on its active conveying flank (4) in a conveying direction (F) at least in a section of the screw (1).

A screw feeder includes: a case that includes a material putting-in portion through which a fluff material is put in and a material putting-out portion through which the fluff material is put out below the material putting-in portion; and a screw that includes a rotational shaft and a blade portion, the rotational shaft being provided rotatably inside the case, the blade portion being spirally mounted on the rotational shaft; wherein the screw is rotated with repeated alternation of a slope-down direction in which the blade portion slopes downward spirally in a vertical direction and a slope-up direction in which the blade portion slopes upward spirally in the vertical direction.

An auger conveyor for transferring, from a first location, a mixed material including granular material and unwanted particulate contaminants, to a second location, the granular material substantially free of the unwanted particulate contaminants, comprising a housing in which there is rotatably supported a conveying member in the form of an auger or screw. A portion of the housing is perforated to provide a tubular screen, and the conveying member includes projecting agitation tabs along a length thereof which is coincident with the perforated portion of the housing, to propel the mixed material in the housing towards the screen so as to urge the unwanted particulate contaminants out of the housing leaving the granular material therein for conveyance to the outlet.

A screw conveyor is provided for lifting a sludge from a collection point. The conveyor includes a lower bearing assembly having a post with a thrust bearing attached to the top, which can be inserted in a socket in the shaft component of the screw. The base of the post is attached to a plate, and the plate can be bolted to the intake end of the tube component of the conveyor. The inner bearing assembly and the intake end of the shaft of the screw are contained within the interior of the tube, such that a seal between the shaft and the plate, which serves as an end cap of the tube, is not required. In an alternative embodiment of the invention, the relative positions of the post and socket can be reversed, with the socket attached to the plate to the intake end of the tube, and the post attached to the shaft component of the screw.

A device (10) for transporting solids that comprises—a support frame (11), —an auger (15) connected to the support frame (11) rotatably about an axis of rotation, —a motor unit (30) configured to activate in rotation the auger (15) that comprises an output shaft (321) being rotatable about an axis of revolution (B), characterized in that the axis of revolution (B) of the output shaft (321) is parallel and eccentric to the axis of rotation (A) of the auger (15).

A novel structure of a spiral conveyor is provided which is also suitable for conveyance of curl-shape and permanent-shape cuttings in a lathe system while suppressing the occurrence of noise caused by vibration. At the lowest point, a conveyance spiral of this spiral conveyor for conveying chips contacts the ground (the ground point P) at the lowest point of a tray, and the conveyance spiral is not in contact with a pair of rails in opposite positions on the inner surface of the tray and extending in the length direction, and small gaps t are formed between the conveyance spiral and the rails. Because it is only at the lowest point that the conveyance spiral contacts the tray, similarly to conventional rail-less designs, a low level of noise is achieved, similar to that in the rail-less designs.

A feeder device for feeding powder, having a barrel feeding channel with a downstream end. The feeding channel including at least one conveying element for conveying the powder material to the downstream end. A rotatable exit element provided at the downstream end of the feeding channel. The rotatable exit element includes an annular portion defining exit openings defined by powder engaging edges. The rotatable exit element is positioned transversally outside the barrel in a proximity of the downstream end of the feeding channel. The feeding channel has a first, inner diameter and the rotatable exit element has a second, outer diameter, where the second, outer diameter is equal to or larger than the first inner diameter.
