A method and apparatus to reclaim metals from scrap material such as automobile shredder residue (ASR) that, after separating out light density components, separates out friable material such as rock and glass by crushing and screening operations to generate a high metal content product.

Floor-standing equipment and methods that employ them use nylon netting and/or fine mesh to trim off leafy matter, break down leafy matter, and separate various aspects of plants from each other. The netting and/or fine mesh is formed into large cylindrical drum into which plant material is loaded through a door flap in the mesh cylinder. An electric motor or handcrank causes the load to tumble over and over a horizontal axle for 3-5 minutes at about 35 RPM. The plant matter trims, separates, and breaks itself down which then drops through the netting, down through a funnel bag into a basin on the floor. The flowers and/or larger plant material are then dropped out separately through the door flap in the netting and through the funnel bag into a second basin on the floor which replaced the first.

A rotary milling system includes a body rotatable about its longitudinal axis and pivotable about a pivot axis that is transverse to the longitudinal axis. The system includes an interchangeable discharge grate and a solid cover for attaching to an open end of the body. The discharge grate includes a plurality of holes through which milled product can pass while grinding media is retained. The body is pivotable to a vertical orientation, where the covers can be changed, and to a horizontal orientation where grinding can be performed with the solid cover attached or discharge can be performed with the discharge grate attached. The discharge grate is sealed to a discharge housing during discharge via an annular seal, where the discharge grate and body are rotated relative to the fixed discharge housing. The discharge grate can include a deflector portion that deflects milled product away from the annular seal.

An apparatus for separating material includes a frame and a rotatable sleeve supported by the frame. The sleeve has a first end, a second end, and a wall with a plurality of apertures to permit material smaller than a first size to fall through the apertures. A source of forced air is arranged to force air through an interior of the sleeve.

An agitator ball mill that includes agitating discs (18) on an agitating shaft drivable in a spinning direction (38), which are provided with entraining profiles (35). These entraining profiles (35) are formed by a trailing wall of a respective channel of a plurality of channels (36). In relation to the spinning direction (38) the trailing wall (39) of an inner channel section (49) runs radially straight relative to the central longitudinal axis (15) and has a length f, and has an outer bent-off channel section (41), which is bent off counter to the spinning direction (38). The outer channel sections (41) are closed radially to the outside by a peripheral portion (42) of the agitating disc (18) having a radial width e.

A closure system is disclosed for the grinding container of a crushing apparatus; the grinding container includes at least one closure plug, an adapter unit having a through-opening, in which the closure plug can be inserted, the latter therefore closing the opening and being retained by the adapter unit, and also includes one or more fixing elements, wherein the one or more fixing elements establish a releasable connection between the adapter unit and the grinding container, in order to secure the adapter unit in removable fashion on the grinding container. Also disclosed is a grinding container having a closure system and further discloses a crushing apparatus.

A discharge grate (200) for an internal discharge end (3) of a mill (1) may be characterized in that it has at least one dynamic variable sieve opening (206) defined between two adjacent floating screen bars (202). The floating screen bars (202) may be configured to a least temporarily move with respect to one another and/or with respect to a holding frame (201) receiving the floating screen bars (202). Temporary expansion of the at least one dynamic variable sieve opening (206) may permit undersized media to pass to the discharge chute (8) and reduce or eliminate pegging.

Certain aspects of the technology disclosed herein include an apparatus and method for forming nanoparticles. The method includes a mechanical milling process induced by aerodynamic, centrifugal, and centripetal forces and further augmented by ultrasound, magnetic pulse, and high voltage impact. A nanoparticle mill having an atmospheric and luminance controlled environment can form precisely calibrated nanoparticles. A nanoparticle mill can include first aerodynamic vane configured to rotate around a central axis of the nanoparticle mill in a first direction, and a second aerodynamic vane configured to rotate around the central axis in a second direction. An aerodynamic shape of an aerodynamic vane can be configured to cause particles within the nanoparticle mill to flow around the aerodynamic vane. The nanoparticle mill can include a primary product line, a nanoparticle sampling line, a particle programming array, a solidifying chamber, or any combination thereof.
