A system for processing compounds having constituent materials of different mechanical characteristics to extract their constituent materials. The system includes (a) a grinder configured to grind a bulk compound material into an initial mixture of tiny particles; (b) a preimpact separator configured to separate the particles into two groups based on their respective mechanical properties, one group being a preimpact mixture comprising the compound particles; (c) a kinetic impactor configured to impact, via an acoustic shockwave, the compound particles of the preimpact mixture, thereby creating a postimpact mixture comprising (i) subparticles of 1.sup.st-constituent-material and (ii) reduced-compound particles comprising a 2nd constituent material; and (d) a postimpact separator configured to separate the reduced compound particles from the postimpact mixture based on a mechanical property.

This disclosure presents a dynamic geometric sorting apparatus designed to organize variously shaped parts efficiently. The system includes a receiving box with an opening for input and an output opening, a base plate with alignment channels on an incline, and a box rake that moves along the base plate. An actuator controls the rake's motion profile, aligning parts into channels. The base plate extends beyond the box, featuring an extension for sorted parts exit. The apparatus adjusts the rake's speed based on its incline position and incorporates a hold down bar to manage part rows during sorting. Additionally, the rake has dividers of different sizes for part separation. The base plate's incline, actuator mechanisms, and a sensor bar with sensors ensure efficient sorting. The method involves applying a motion profile to parts in the box, aligning them into channels, and releasing them once sorted.

A hydraulically powered separator includes a separation chamber, an auger, a restrictor ring mounted at an output end of the chamber, a hydraulic cylinder having a reciprocating ram, a proportional hydraulic valve operatively coupled to the hydraulic cylinder, and a controller operatively coupled to the proportional hydraulic valve so as to control the hydraulic cylinder in a closed-loop manner. The chamber receives and processes a food product and has a cylindrical screen including a plurality of apertures. The auger is rotatably disposed within the chamber and an annular space and a volume is defined between the auger and the screen. The restrictor ring can be linearly and reciprocally displaced. Linear displacement of the restrictor ring varies a size of the volume. Movement of the ram causes pivoting movement of the restrictor ring to reduce or increase the size of the volume.

Systems and methods for classifying, evaluating, and sorting materials within a contiguous stream of materials. Segments of the material stream are classified and evaluated, whether such segments make up a whole material piece or a portion of a material piece. The sorting is then performed as a function of the classifications and evaluations.

A method of recycling scrap is disclosed, comprising the steps of shredding the scrap with a shredder into shredded scrap objects, classifying the shredded scrap objects into fractions of scrap objects having different size ranges with a classifier, and sorting scrap objects while substantially maintaining interspace between the objects. Further, a singulating arrangement for singulating scrap objects is disclosed, comprising a substantially horizontally disposed feeder that extends from a receiving area for receiving scrap objects to a feed gate positioned at a top portion of a chute, as well as an ejector arrangement, comprising a conveyor with a substantially flat conveying plane and an ejector device disposed along the conveyor.

Disclosed herein are a substrate sorter, an inspection and sorting system having the substrate sorter, and a method for the inspection and sorting system. The substrate sorter includes an annular gripper comprising a rotator and a plurality of vacuum applicators concyclically disposed around an axis, a carrier operable to move a substrate towards the rotator and into a loading region below the rotator, and an actuator coupled with the annular gripper and operable to rotate the rotator about the axis relative to the plurality of vacuum applicators while one or more of the plurality of vacuum applicators hold the substrate against the rotator.
