The present invention provides a mobile multi-deck screening apparatus for screening a mixed material into three graded streams, the apparatus comprising two or more overlapping screening decks and at least three discharge conveyors, wherein one discharge conveyor is a switchable conveyor selectively switchable between an active state such that each discharge conveyor discharges one graded stream, to an inactive state such that one discharge conveyor discharges two graded streams.

The present disclosure is directed to a rotary drum trimming apparatus for trimming plants, in particular, buds and flowers, to remove unwanted plant material. More specifically, the present disclosure is directed to a rotary drum trimming apparatus that incorporates a separator for efficiently separating severed plant material from an airstream that carried the severed plant materials away from a rotary trimming drum

A container such as a barrel or drum is provided for processing of solid material or parts with a liquid. The container is designed with grooves leading to holes or slots in the side that draw liquid into the container due to the rotation of the container when it is immersed in a tank of liquid. The holes or slots have a small dimension in the direction of rotation to minimize the probability of solid material coming out of the container. The fluid flow caused by the rotation serves to increase the rate of solution replacement inside the container as well as to keep the solid material from falling out through the holes or slots. The container disclosed is useful in processes in the plating, etching, leaching, and surface finishing industries.

The present invention relates to a system for melting aluminum and recycling black dross, including an aluminum melting furnace responsible for melting aluminum scraps in molten aluminum and a black dross recycling device responsible for recycling black dross generated when the aluminum scraps are melted in the molten aluminum. The aluminum melting furnace includes a heating chamber provided with heating units responsible for heating the molten aluminum; and a melting chamber provided with an eddy unit responsible for generating an eddy descending in a spiral in the molten aluminum, a flux supply unit responsible for adding a flux to the eddy, and a raw material supply unit responsible for adding the aluminum scraps to the eddy, wherein, in the eddy unit, black dross formed when inclusions contained in the molten aluminum are captured by the flux is repeatedly descended and floated in the molten aluminum through the eddy, so that the black dross is collected into a spherical shape to form spherical black dross, and the black dross recycling device is responsible for recycling the spherical black dross.

A nut sorter includes a support frame with a rotatable cage connected thereto. The rotatable cage is comprised of support rings with a plurality of longitudinally extending rods connected thereto. The outer periphery of the longitudinally extending rods extends inwardly into a center space defined by the inner diameter of the support rings. The nut sorter also has a plurality of scrapers utilized to dislodge stuck debris and nuts as the cage rotates under the scrapers.
