Abstract: A material processing vibrating screen with diverting systems configured to deliver material, via a plurality of material diverters, to locations closer to a feed end of the screen than would otherwise be done in the absence of the diverters. The diverters can be fixed to a cross member, the underside of a screen, and may be adjustable and easily replaceable. The materials for the deflectors can vary depending upon the material being screened. The screen may be also be a variable sloped vibrating screen.

Abstract: A method for detecting mentholated tobacco, comprising irradiating tobacco containing menthol and a fluorescent taggant with radiation and observing the tobacco for fluorescence from the taggant. A system and method for detecting and separating mentholated tobacco from non-mentholated tobacco within a product stream is also provided.

Abstract: A method for separating solids from a drill cuttings and drilling mud mixture feed in a shale shaker includes providing a shale shaker (1) having a basket (4) including a stack of at least two screen decks (8,8a, 8b), wherein the screening surfaces (9,9a, 9b) of the decks are spaced apart and superposed one above the other. A fluid retaining wall (5) and the feed receiving end (12a, 12b) of the screening surface of the lowest screen deck define a pond region (15). In use of the method a drill cuttings and drilling mud mixture feed (18) forms a pond of solids and liquid in the pond region that immerses a portion of the screening surface at the feed receiving end of each of the two screen decks. Apparatus for use in the method is also described.

Abstract: A mining shovel with compositional sensors comprises a bucket having various inward looking sensors positioned throughout the bucket. The bucket can also have disposed thereon a control enclosure that houses processing equipment that receives and analyzes the data collected by the inward looking sensors. The mining shovel with compositional sensors can be used as part of a system to manage a mining field, including generating and transmitting instructions directing where to deposit material located in the bucket based on the data collected from the inward looking sensors positioned in the bucket.

Abstract: The invention is a portable prospecting and classifying self-contained apparatus having a bucket, a supporting classifier screen and a supported classifier screen setting freely within the bucket, having a bucket handle and a bucket lid closing securely over the bucket. The supported classifier screen has a screen mesh and a screen handle, allowing the user to lift the supported classifier screen from the bucket. The supporting classifier screen has a screen mesh which may be of a finer mesh than the supported screen mesh and a supporting classifier frame. A prospector uses the portable prospecting and classifying self-contained apparatus invention by scooping or pouring mineral material into the bucket with an earth digging scoop or gold pan. The supported classifier screen and the supporting classifier screen are adapted to classify and separate mineral material from coarse to finer grain material when poured into the bucket.

Abstract: Provided is a sort workpiece sorting system including: a conveyor; a conveying position detection part for workpieces; a camera configured to photograph the workpieces; robots provided with a hand disposed along a conveying direction and capable of ejecting workpieces on the conveyor, and a weight measurement part; a control part configured to control each robot; and a large group classifying part configured to classify the workpieces into large groups allocated to the robots based on an image of the workpieces. The control part includes a visual tracking part configured to cause the robots to handle the workpieces while following an operation of the conveyor based on the image of the workpieces and a conveying position. The visual tracking part causes the visual tracking part to eject the classified workpieces are ejected from the conveyor by the hand, and the workpieces are sorted for each group based on the measured weight.
