摘要： The system (10) is particularly suited for reclaiming used foundry sand by means of thermal reclamation. The used sand, which preferably is first fed through a lump-crusher, shake-out apparatus (12), is made to pass through thermal reclaimer means (14) while being heated to a predetermined temperature for a preestablished period of time in order to accomplish the burning away of the organic materials, i.e., matter, which are present in the used sand. From the thermal reclaimer means (14), the used sand passes to and through the post reclaimer means (15) for further reclaiming and then to and through the primary cooling means (16) wherein the heated sand is cooled to a suitable temperature. The separator means (18) is operative to effect the removal of tramp metal from the cooled, thermally reclaimed sand. Thereafter, the cooled, thermally reclaimed sand is made to pass through the classifying and dust removal means (19) for classifying and removal of dust and fines and then through the scrubber means (20) wherein the dust associated with the particles of sand is removed therefrom. Finally, the substantially dust-free, cooled, thermally reclaimed sand passes through the secondary cooling means (22) wherein the sand is further cooled to substantially ambient temperature.

摘要： A rotary tumbler metal reclaimer includes an inner cylinder and a concentric outer cylinder that rotate simultaneously. The inner cylinder includes a first compartment that intakes material for breaking by teeth, a second compartment that receives broken material from the first compartment and crushes the material into smaller particles, and a third compartment wherein particulate material enters the space between the inner cylinder and the outer cylinder by attrition through perforated screens. The second compartment includes a crusher having various features for crushing lump material as it rotates. The third compartment provides further breakage and conveyance of particulate material. Particulate material then returns proximate the intake for screening into fine and coarse sizes and then collecting for reuse. Metallics and metallic oxides exit the tumbler through apertures in the rear of the third compartment for collection. The tumbler reclaims metals, metallic oxides, sands, and other materials for reuse.

摘要： An attrition mill (10) for reclaiming foundry sand from deposited material having lumps of used foundry sand and included material includes a housing (12) defining a chamber (14) for receiving the lumps of used foundry sand and included material. A base (20) is disposed within the housing (12) and has an elevated end (22) defining a reject outlet adjacent a reject end of the mill (10) and a lower end (24), and a discharge wall (26) is positioned adjacent the base lower end (24) to define a sand outlet adjacent a sand end of the mill. A resilient support (32) is attached to the housing, and a vibratory drive (34) is attached to the housing (12) and includes first and second eccentrically loaded motors (36, 38). The vibratory drive (34) is selectively operable in a normal mode, in which the first and second motors (36, 38) are rotated to generate a vibratory force in a first direction that advances the deposited material generally toward the sand outlet, and a reject mode, in which at least one of the first and second motors (36, 38) is operated to generate a vibratory force in a second direction that advances the deposited material generally toward the reject outlet.

摘要： The method permits recovery of spent foundry sand for reuse by eliminating, by combustion, the organic carbon substances with which the spent sand is impregnated; spent sand, after grinding to a uniform grain size, is placed into a cylindrical container (2) inclined with respect to the vertical and rotated slowly (4-6 revolutions per minute); then, a stream of oxygen is blown into the base of the receptacle through a distributor (5) which uniformly distributes it into the spent sand mass (20), and local combustion is initiated on the surface of the sand mass, at the top of receptacle, by means of a burner (31); finally the burner is extinguished whilst the delivery of the oxygen stream is maintained and the combustion proceeds and feeds itself by the effect of a progressive descent of the flame front (30) towards the base of the receptacle until complete destruction of the organic and carbon substances contained in the sand has taken place.

摘要： The core removal apparatus (1) is comprised of a portal-shaped carrier frame (2) of which the uprights (4) and the support brackets (5) carry each a bearing (7) on which there is arranged by means of a swivelling lever (9) a reception device (11) which is pendularly suspended and free to swivel. Said device has two longitudinal arms (14 and 15) on which there are provided two vibration generators (23) and two stop strips (20), respectively an impact plate (19), a reception opening (16) being arranged between the latter and at the rear portion of said opening a plurality of support ribs (17) are provided. A casting (a) loosely introduced into the reception opening (16) and the reception device (11) is subjected to vibratory oscillations by the vibration generator (23). Since these vibrations are also induced in the casting (a), the latter is rapidly and loosely moved with a reciprocating motion between the impact plate (19) and the stop strips (20) inside a delimited play space (c), violently impacting them. Owing to this arrangement and to the vibrations induced in the casting (a), the sand cores contained therein are reduced to sand which then falls down.

摘要： A regeneration process for foundry sand, in particular active bentonite-containing used sand, dispenses with preliminary thermal treatments and allows most valuable substances contained in the used sand to be recovered. The sand is partially fluidized with air in a grinder, by means of which valuable substances and dust are continuously carried out and separately collected. The considerably increased grinding and dedusting performance requirements caused by the suppression of preliminary thermal treatments are met by a composite system of separate grinding and dedusting areas through which the sand continuously circulates in a vertical circuit.

摘要： A method is shown for controlling the oxidation and calcination of waste foundry sands during a thermal reclamation process. The waste sands are passed to a calcining chamber having a floor, connecting sidewalls and a top. The floor of the calcining chambers provided with a plurality of vents. The calcining chambers also connected to a separate firebox which produces fluidizing hot gases for fluidizing waste sands within the calcining chamber and forming a fluidized sand bed. The fluidizing hot gases are introduced into the calcining chamber by means of the floor vents. By precisely controlling the temperature of the waste sands within the fluidized bed, a more consistent product is produced while maintaining the temperature of the waste sands below a critical temperature at which the organic binders present on the sand grains would be fused to the waste sand grains.
