Abstract: Disclosed herein is a method and depackager apparatus for removal of organics and cleaning of residual plastics from a waste stream in a depackager. The method comprises injecting a stream of air into a filtration drum, comprising the residual plastic, of the depackager. Further, the method comprises creating a turbulence within the filtration drum using predetermined structures deployed in the filtration drum, such that the residual plastic passes through a first end of the filtration drum to a second end of the filtration drum. Finally, the method comprises collecting cleaned residual plastic through the second end of the filtration drum.

Abstract: Organic waste is polished to remove floatable contaminants prior to being biologically treated. In one application, pressed organic waste is polished before being sent to a wet anaerobic digester, optionally to be co-digested with wastewater treatment plant sludge. The organic waste is polished by flinging globs of the organic waste against a screen (3,4) while flowing air across the flinging globs. The polishing can be performed in a device having a rotor (6) with discrete paddles (9,10) inside of a cylindrical screen (2,3,4).

Abstract: A rotary milling system includes a rotatable cylinder, a discharge grate, a movable flap valve into and out of engagement with the grate, a discharge housing surrounding the grate, and a conveying pipe extending from the discharge housing. The cylinder can include grinding media for abrading a product when the cylinder is rotated. The product can be in either a dry form or within a liquid medium. Upon conclusion of the milling, the flap valve can be opened to allow the milled product to pass through the grate and into the discharge housing. A negative pressure can be applied to draw the milled product through the conveying pipe into a separator tank.

Abstract: In a method of reclaiming constituent components of sealed batteries, the batteries are initially ground to form a ground feedstock. The ground feedstock is heated to form a dried feedstock. The dried feedstock is screen separated into a coarse fraction and a powder fraction, the coarse fraction including a magnetic fraction and a non-magnetic fraction. The coarse fraction and the powder fraction are further vibratorily segregated. The magnetic fraction may be magnetically extracted from the coarse fraction, while the powder fraction is outputted.

Abstract: Plastic sheet elements (19) having a size and deformation suitable for use as a filling material in pillows, duvets and the like are manufactured by feeding one or more plastic sheets to a shredding apparatus (6) which has a rotating drum (9). Loosely hanging knives (12) are mounted (11) near an outermost edge of the drum (9), and are pivoted outwards during rotation to thereby cut, deform and twist the sheet to form “curly” elements (19), which are sucked out through openings (14) in a screen (8) located below the drum (9). By adjusting the feeding of the sheet (4), the rotation of the drum (9) and the magnitude of the negative pressure, various sizes and configurations of cut individual sheet elements (19) are produced.

Abstract: A solid waste comminuting apparatus (10) for reducing solid waste material (12). The apparatus (10) has rolls (42, 44) for severing material that is fed into the entrance (32). After the material is severed, it is carried by an airstream to a fan (112). The subdivided pieces are directed to a separator screen (131) mounted within the centrifugal housing. The airstream carries the small pieces (14e) through the separator screen (131) into an outer volute chamber (135) for discharge from the apparatus. The large pieces (14a-14d) which do not pass through the separator screen (131) are recycled through a recycle outlet (143) and a recycle conduit (150) back to the rolls (42, 44) for further size reduction.

A lower part of the bran-removing cylinder is extended downward so as to face horizontally to the rotary roll.

Abstract: Residues from fibermat materials are broken down and separated into wood fibers and other fibers so that the fibers may be recycled. If the fibermat residues are not recycled, they present a disposal problem due to the uncured resins that become toxic waste. The fibermat residues are cut and separated by rotating cutting heads within a cutting and separating chamber. The wood fibers, being the heavier fibers, settle out, pass through a screen into a collection chamber and the lighter textile fibers are sucked out of the cutting and separating chamber with a vacuum system.

Abstract: A method is provided for filtering shredded cellulose-based material, for example to enable the formation of a mixture containing cellulose dispersed in a solvent for cellulose such as amine oxide. The shredding operation creates both fine particles of cellulosic material ("pulp dust") and large particles of cellulosic material. The shredded cellulosic material is passed through a separator to separate the pulp dust from the large particles of cellulosic material and the pulp dust is subsequently recovered in a filtering process.

Abstract: An apparatus for comminuting waste material such as waste plastic sheet material, into progressively smaller pieces until a desired size is reached that may be recycled. The apparatus has a set of slowly rotating, intermeshing scissor rolls for receiving the waste material and shearing the material into smaller pieces. A paddle wheel conveyor receives the smaller pieces from the scissor rolls and moves the smaller pieces over a screen with the undersized smaller pieces passing through the screen defining the desired reduced size. The oversized smaller pieces that do not pass through the screen are reprocessed back to the scissor rolls by the paddle wheel conveyor. A vacuum pump draws air through the apparatus and the screen to facilitate the separation on the screen and entrains the undersized pieces in an air stream to convey the pieces from the apparatus.

Abstract: A milling apparatus comprises a container with a plate extending across the container and movable relative thereto by an oscillator which communicates oscillatory movement to the plate at right angles to its plane. The oscillation can be tuned so that the natural frequency of oscillation of the plate and communication means is the same as or a whole number multiple of the oscillation frequency of the oscillator. The oscillator comprises a rotatable eccentric member driven to provide mechanical oscillations. The plate within the container acts to agitate grinding elements provided within the container. The container can either be used in a batch mode by moving the plate from an inlet to an outlet or in a continuous flow mode in which the comminuted material passes the plate from an inlet to an outlet.
