A system and method for a vacuum driven separating device is disclosed.

Tables for sorting agricultural producta. The tables include legs, a deck, and a vibration generator. The deck is supported on the legs. The deck includes a loading end, a terminal end, and a grate. The terminal end is opposite the loading end. The grate extends between the loading end and the terminal end and defines the grate openings. The vibration generator is mounted to the deck and configured to vibrate the deck. The grate supports agricultural products that are larger than the grate openings. Agricultural products that are smaller than the grate openings pass through the grate. The vibration generator vibrating the deck causes the agricultural products to move across the deck over the grate.

A mobile mineral material processing station has a mobile platform having tracks or wheels or a skids for supporting or forming a body that supports in line, in a transport configuration: a feed conveyor; a screen frame and a multi-layer screen; first and second exit conveyors; and a third exit conveyor on top of the first and second exit conveyors. The first exit conveyor turns from a transport position, under the third exit conveyor, to a first operation direction, onto a first side of the station, for operating the station, and back. The second exit conveyor turns from a transport position, under the third exit conveyor, to a second operation direction onto a second side of the station, opposite to the first side, and back.

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.

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.

The enclosure contains a plurality of stacked screens, the stacked screens have openings that decrease in size from a top of the stack to a bottom of the stack. The method also comprises introducing the mixture to an uppermost one of the plurality of stacked screens; moving the plurality of stacked screens to cause the oxidizable catalyst material to separate from and migrate to a location beneath the inert support media; conveying the separated inert support media to a location outside the enclosure for disposal as non-hazardous waste; and conveying the separated oxidizable catalyst material to a location outside the enclosure for at least one of reclamation, or thermal destruction.

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.

A manoueverable crushing and screening system (50) is disclosed. The manoueverable crushing and screening system (50) comprises of a chassis (52) with a manoueverable undercarriage (58). The system (50) also comprises of a crushing unit (53) mounted at one end of the chassis (52) and a screening unit (51) that is mounted on the other end of the chassis (52). A steep angle conveyor (55) is configured between the crushing unit (53) and the screening unit (51) and the steep angle conveyor (55) is operable between a first position (A) and a second position (B). In the first position (A), the steep angle conveyor (55) conveys crushed material from the crushing unit (53) to the screening unit (51). This configuration of the system reduces operating length of equipment and also reduces length of the plant.

A screening bucket comprises a main structure which includes a collecting portion for the material to be screened and a receiving member in which there is collected the material which is subjected to sieving and which has a discharge opening for the screened material. A plurality of rotating elements are arranged in the region of the discharge opening and are supported in a removable manner on pairs of opposing bearing groups. The bearing groups comprise a bearing and a rotatable support, to which there is connected an end of the rotating element by means of a male/female connection, wherein the rotatable support further comprises a locking portion which is capable of being retained by means of a corresponding retention device so as to prevent the rotation of the rotatable support when the rotating element is removed.
