A machine or apparatus featuring a first processor and a second processor. The first processor is configured to receive a mixture of fluid, valuable material and unwanted material and a functionalized polymer coated member configured to attach to the valuable material in an attachment rich environment, and provide an enriched functionalized polymer coated member having the valuable material attached thereto. The second processor is configured to receive a fluid and the enriched functionalized polymer coated member in a release rich environment to release the valuable material, and provide the valuable material released from the enriched functionalized polymer coated member.

The present invention relates to a screening apparatus (100) comprising a frame (10); a feed conveyor (20) mounted at one end of the frame and a screen (30) for accepting waste material from the feed conveyor, the waste material comprising fines and oversize material. The screen (30) is mounted on the frame (10) about a pivot axis and comprises a trough (32) with a top opening; and a plurality of driven elongate rotating members (40) disposed in an arc along one side of the trough and along at least a portion of the base of the trough (32) for causing circular or helical flow of the waste material within the trough. The trough (32) further comprises a base opening for discharging the fines material and an oversize material outlet for discharging the oversize material; and wherein the screen is mounted on the frame such that the elongate rotating members (40) are each independently perpendicular to the pivot axis.

A screen drive for a mobile material processing screen which can be at a travel width without having to fold or disable the screen drive. The screen drive system includes a drive motor, which is tucked at least partially under the vibrating screen; a sheave, having a double row ball bearing being supported by a shaft; a belt, coupling sheave and drive motor; a drive shaft coupled to a first universal joint, and a second universal joint, which is coupled to an opposing end of the drive shaft and to sheave.

The invention relates to a charging unit of a material processing apparatus having a charging hopper, the side walls (22) and rear walls (23) of which can be folded over between a working and a transport position by means of actuators (40, 50). A deflection element is provided, which converts the movement of an actuator during a portion of a movement thereof into a rotational movement of the rear wall or of the side wall and, during a further portion, into a translational movement. As a result of the rotational movement, the rear and side wall can be pivoted between the working and transport position, while by means of the translational movement, the rear and side wall can be connected to each other by means of an appropriate closure (60). By means of the deflection element, a simple, self-securing, and economical structure of the charging hopper is made possible.

Machine, especially a padding machine, for the burying of pipes, in particular arranged in a respective excavation of the ground, quali gas pipelines, oil pipelines, aqueducts, or altri, in particular for la covering of said pipe with a corresponding material, in particular un treated material, preferably screened or frantumato, including a main support framework of the apparatus, in particular which extends according to a respective longitudinal axis of the same machine, a cabin for housing the driver of the machine, such a cabin is in the form of a cabin movable with respect to said main support frame. Said cabin for housing the driver of the machine can be positioned, in corresponding vertical positions, or placed at height levels different from each other, preferably moving vertically, or perpendicularly to said ground.

An apparatus for sifting soil and other material comprising a trammel and a frame with legs allowing it to be fitted to a wheelbarrow or other rolling container device.

A mobile machine for separation and recovery of spent shot, the machine including a drive unit to provide self-propelled mobility to the machine, a charged soil collection assembly mounted relative to the drive unit to collect soil charged with spent shot, and at least one separation assembly to separate spent shot from other collected material, the spent shot conveyed to a collection vessel for disposal.

A system for segregating a mixture of oxidizable catalyst material and inert support media. The system comprises an enclosure configured to contain inert gas. The enclosure includes a plurality of stacked screens disposed therein. The stacked screens include openings that decrease in size from a top of the stack to a bottom of the stack. The enclosure also includes an inlet to deliver the mixture to an uppermost stacked screen and outlets to direct the separated support media and catalyst material to a location outside the enclosure.

A screening machine having a machine frame that is mounted so as to be capable of vibration and is capable of being set into vibration, and having screening elements configured in a row in or on the machine frame, seen in the longitudinal direction of the screening machine. The screening machine is subdivided into a plurality of screening machine parts that are connectable or capable of being assembled to form the screening machine. An individual screening machine part or one or more stacks of a plurality of screening machine parts stacked one over the other have dimensions that are smaller in their length, width, and height than the corresponding dimensions of the interior of a commonly used standard transport container or than dimensions requiring special transport due to excess size.

A method of disposing of a mixture of oxidizable catalyst material and inert support media. The method comprises introducing inert gas into an enclosure; introducing the mixture into the enclosure; separating the oxidizable catalyst material and the inert support media within the enclosure; maintaining an inert gas environment around the oxidizable catalyst material during separating; exporting the separated inert support media from the enclosure; and grinding the separated oxidizable catalyst material into a powder for disposal as hazardous waste via incineration.
