A method of forming a compact includes removing material from a workpiece, transferring metallic dust released during the material removal into a conduit, operating a plurality of slide gates to selectively control movement of the dust from the conduit to either one of a primary collector and a back-up collector, drawing the dust through the conduit to a compactor, and compacting the dust in the compactor.

A method and a system produces extrusion billets from scraps obtained from stamping, cutting and/or machining operations, in particular scraps made of magnesium or magnesium alloys, without subjecting these to a melting process. The system for carrying out the method is essentially composed of a storage unit for the scraps, a device for comminuting the scraps, a press for producing a round briquette, and an extruder for shaping the round briquette into a extrusion billet.

The present disclosure is for a briquetting machine and method thereof to process loose metal scraps. The method comprises the steps of advancing a pre-extruding punch in a first pathway to push loose metal scraps towards a first entrance leading into a re-extruding cavity; advancing a re-extruding punch in a second pathway perpendicular to the first pathway to further push the loose metal scraps towards a second entrance leading to a final pressing cavity; advancing a final-extruding punch along a third pathway perpendicular to both the pre and re-extruding punches to compress loose metal scraps to form a metal cake in the final extruding cavity. Pressure and overflow release areas are configured adjacent to each entrance. Advancing and retracting sequences of the pre-, re-, and final-extruding punches are monitored and controlled via sensors and switches.

A reverse vending machine is provided that includes an interface cabinet having an inlet portal. At least one bin is provided for receiving the accepted recyclable container. A roller system identifies and sorts the recyclable containers. A crusher is driven by a motor with a mechanical coupling between the crusher and the motor. The crusher is adapted to receive various containers and is positioned intermediate between the roller system and the bin. A cart or frame displaceable relative to the interface cabinet, the crusher is mounted on the cart or the frame. A reverse vending machine in another embodiment includes a interface cabinet, the interface cabinet having an inlet portal for recyclable container input and a rejected container depository. At least one bin and a roller system are provided along with a wash system for cleaning components of the interface cabinet between the inlet portal and the bin.

An apparatus for collecting dust from a cutting unit is provided. The apparatus includes a rotary valve operatively connected to the cutting unit, a conduit in fluid communication with the rotary valve, and a compacting machine disposed downstream from the conduit and configured to receive dust from the conduit. A blower is configured to pull air downstream to carry the dust into the compacting machine. The compacting machine produces a compact from the dust.

A briquetting machine for loose metal scraps comprises a pre-extrusion part, a re-extrusion part and a final pressing part. On the upper portion of a pre-extrusion cavity (14) of the pre-extrusion part, a pre-extrusion releasing area (15) is formed near to one side of a re-extrusion cavity (24). At the front end of a re-extrusion plunger (23) of the re-extrusion part, a lateral gap (28) is formed near to one side of the pre-extrusion cavity. The cross section of the lateral gap is a right-angled trapezoid and the lateral gap is provided with a lateral slope (29). A briquetting method for loose metal scrapes is disclosed. By way of pre-extrusion and step-by-step feeding and triggering resetting loading, not only is a certain pre-pressing effect guaranteed while the loose metal scraps are processed in each feeding and pre-pressing step, but also the stress can be transferred and released timely under the over-pressure condition, which avoids the formation of dense metal block under the over-pressure condition. Therefore a continuous, automatic and safe pressing operation is assured.

Embodiments relate to the technical field of waste collection, in particular to waste collection equipment, which includes a temporary storage tank, a pressing tank and a pressing mechanism; the temporary storage tank is configured for receiving and temporarily storing wastes produced by die cutting equipment; the pressing tank is configured for carrying the wastes in the temporary storage tank; the pressing mechanism is configured for compressing the wastes in the pressing tank; the temporary storage tank is provided with a first blanking port, which is configured for communicating the temporary storage tank with the pressing tank; the first blanking port is provided with a first valve; and the first valve is configured for opening or closing the first blanking port to control whether the temporary storage tank discharges the wastes.
