摘要:
A material separating apparatus which is particularly suitable for sorting different forms of waste material comprising: a carrier, generally a table (1) having a surface (10) onto which material can be deposited; and a drive means (3) for providing said carrier surface with a reciprocating motion in the plane of said carrier surface; the drive means being arranged to provide, in use, an abrupt change of direction of the carrier surface at each end of its travel to provide a motion to cause different components of the material to be separated in consequence of obtaining different velocities in dependence on their physical properties, and the table surface having different sloping zones for channelling out different materials. The drive means uses an offset crank linkage which collapses at the end of travel in each direction enabling the inertia of the table to continue until it hits a stop and is then drawn back in the reverse direction by the linkage.

A device for separating lighter insulation material from heavier metallic material present in decomposed electric cables or the like, which device comprises an inlet (8) for mixed insulation and metallic material, and a first outlet for the insulation material and a second outlet for the metallic material, separate from the first outlet. The device further comprises a track (40) inclined relative to the horizontal plane, to which the mixed material is delivered from the inlet and which is profiled such that when a reciprocating movement is imparted thereto essentially in the plane of the track, the metal material is transported towards the upper end of the track where it is fed out through the second outlet while the insulation material is transported towards the lower end of the track where it is fed out through the first outlet.

A nonferrous material sorting apparatus comprises a screening device (1) for screening nonferrous materials to be sorted into materials of a plurality of size ranges, a first sorting device (2) for sorting the nonferrous materials of the minimum size range according to the weight ratio by an inclined vibrating air table (20) supplied with air, and a second sorting device (4) for sorting the nonferrous materials of the size range larger than the minimum size range according to the size in specific gravity of the nonferrous materials relative to constituent materials of a fluidized bed.

In an arrangement for the separation of waste materials, in particular domestic waste materials, is included a separating table (10) arranged at an angle to the horizontal plane, with a lower part (11) and an upper part (12). The separating table as a whole, or longitudinal segments in the same, describe rotating movements whilst largely maintaining the orientation in relation to the horizontal plane. A feeder (20) adapted as a shaking table is provided in its output part (21) with fingers (22) oriented largely in the direction of movement of the goods. These form gaps between themselves which allow goods of dimensions smaller than the gap width to pass so as to fall down onto the separating table (10). At least parts of the gaps are located above the lower part of the table which forms a larger angle with the horizontal plane than the upper part of the table.
摘要:
Multi-phase systems are treated to enhance separability of at least one phase by establishing the multi-phase system in pre-determined relation to a transducer (24) and subjecting the so established system to at least two vibratory disturbances which differ from one another so as to thereby form respective wave trains at different frequencies within the audio frequency range and thus establish a beat frequency difference, said one phase being thereby separated from the other phase(s). The expression "multi-phase system" includes solid-solid systems such as mixtures of solid particles and also fluid characterised systems such as colloidal dispersions, suspensions and emulsions.
摘要:
Processes by which a mixture of two or more discrete particulate materials, each of the materials having a different sliding coefficient of friction, can be separated using methods which take advantage of velocity differences generated by application of a force to the mixture over a surface as a function of its sliding coefficient of friction. In a first embodiment, the mixture is fed by a supply means (116, 118, 120) to the surface of a rotating disc (122), whereby the materials will be induced to move by centrifugal action. A second embodiment employs a surface (230) inclined to the horizontal and vibrated, causing materials of different coefficients of friction traverse the surface (230) along separate paths. A third disclosed embodiment uses an inclined slide (316) to provide separate momentum effected paths to the materials.
摘要:
Bei einem Verfahren zum Trennen der Bestandteile einer heterogenen Menge aus festem Material, bei dem das Material ggf. zerkleinert, getrocknet und danach in Fraktionen getrennt wird, soll die Fraktionierung unabhängig sein von der Korngröße. Dies wird dadurch erreicht, daß die Menge auf einem muldenförmigen Träger (2) einer die Absonderung der spezifisch schweren Bestandteile nach unten und der spezifisch leichten Bestandteile nach oben hervorrufenden Vibration ausgesetzt wird und danach die Fraktionen (35, 36, 37) in unterschiedlichen Schichthöhen entnommen werden. Außerdem wird eine Vorrichtung zur Durchführung des Verfahrens vorgeschlagen.
摘要:
Process and device for delabeling of plastic containers by immersing them in a liquid bath heated to above the disorientation temperature of the containers and thereafter separating the loose lables (optionally cups) from the container bodies by bringing them on an inclined sieve vibrating in such a way that when the screen deck is in its highest position in the vibrating motion, the component of motion parallel to the screen deck is directed towards the highest point of the screen.
