| 32 | Arrangement for dry reconditioning of used foundry sands | US39308 | 1993-07-12 | US5421462A | 1995-06-06 | Hermann Hofbauer; Erich Muller; Erhard Putzig; Ekart Schaarschmidt |
| An arrangement for the dry reconditioning of used foundry sands in which used sand is fluidized with air or an air/gas mixture and flung against a precipitator to separate and remove substances covering sand particles. The precipitator has several planar baffle elements arranged in concentric circles around a conical deflector. A jet of used sand/air directed toward the deflector expands radially outwardly toward the baffle elements so that the jet is decelerated several times by the deflector and the baffle elements and, in a confined space, split into individual streams and swirled to provide heavy mechanical friction between sand particles and between sand particles and the baffle elements. | ||||||

| In a method of regenerating feed material of coated grains with an irregular surface, in particular used foundry sands coated with a casing of binder or the like, the casing is opened up by friction, wherein the sand to be regenerated is brought into rubbing contact with a granular scouring agent, the grain size of which is substantially smaller than that of the sand. | ||||||
| 34 | Sand lump crushing device | US308092 | 1981-10-02 | US4637559A | 1987-01-20 | Joseph E. Bowling; James H. Carpenter; Russell L. Rowe |
| This relates to a device for crushing sand lumps. The device includes a tub which is resiliently mounted and is provided with means for vibrating the same in a generally vertical direction parallel to a rear wall of the tub. The tub rear wall is hollow and is provided on the inner face with perforated crusher plates. Sand flow through the crusher plates is down through the hollow rear wall and there is an upwardly directed airwash for the falling sand. The lower portion of the rear wall is in the form of a door mounted for swinging movement about a horizontal axis. The door is operated by a cylinder having an axis parallel to the direction of vibration and the door is opened during the vibration of the tub so as to direct scrap and uncrushed lumps out through the lower portion of the rear wall in the same direction of salvaged sand flow. The crusher plates include a main wall having elongated slots forming the perforations and there are lugs projecting forwardly from the main wall above and below the slots with the vertical dimensions of the lugs and slots and the spacing thereof being in accordance with the amplitude of intended vibration to provide a maximum crushing effect. | ||||||
| 35 | Apparatus for removing no-bake coatings from foundry sand and classifying the reclaimed sand | US250238 | 1981-04-02 | US4354641A | 1982-10-19 | William J. Smith |
| An apparatus for reclaiming no-bake foundry sand is provided, in which a fluidized stream of pneumatically conveyed particles of no-bake coated sand grains traveling at velocity sufficient for transport is discharged against a target to fracture the no-bake rigid coatings from the sand grains on impact. Certain of the fractured coatings are removed and the sand grains along with any remaining fractured coating particles are directed through a passageway having a fluidizing air stream induced therein. The air stream entrains and carries off the fractured coatings and the fine sand grains so that only sand grains of desired particle size pass through the air stream for subsequent reuse. Advantageously, the velocity of the air stream is controlled by regulating the cross-sectional area of the passageway at the point at which the air stream is induced. | ||||||

| Method for purifying foundry sand which involves the passage of sand through layers of steel wool supported on perforated discs mounted on a vertical shaft in a standpipe. Perforations in the sides of the standpipe permit air to be blown through the sand as it drops down through the steel wool. The vertical shaft supporting the discs and steel wool is vibrated to cause the sand to move through and past the packs of steel wool. | ||||||

| 38 | Apparatus for conditioning a granular material | US3782643D | 1972-05-17 | US3782643A | 1974-01-01 | CARPENTER J |
| In an apparatus for conditioning a granular matrial, a centrifugal throwing wheel projects the material radially against an impact surface which completely surrounds and is spaced from the periphery of the wheel. An air stream is moved between the impact surface and the periphery of the wheel so as to remove contaminants from the projected particles.
