| 188 | METHOD OF PRODUCING FOAMED SAND AND PRODUCTION APPARATUS FOR PRODUCING FOAMED SAND | US15770918 | 2016-10-25 | US20180326473A1 | 2018-11-15 | Takumi MAEGAWA; Masashi MORIKAWA; Kenichiro MORI; Yusuke KATO |
| Provided is a method of producing foamed sand (s) for forming a sand mold. The foamed sand (s) includes sand particles (p) and foam (f) adhering to surfaces of the sand particles (p). The foam (f) contains water glass (b), water (w), and a surfactant (c). According to the method, an aqueous surfactant solution (e) in which the surfactant (c) is dissolved is frothed to generate froth (d) from the aqueous surfactant solution (e). Then, the generated froth (d), the water glass (b), and the water (w) are kneaded with the sand constituted by the sand particles (p). | ||||||

| 190 | METHOD OF REUSING CORE SAND | US15949394 | 2018-04-10 | US20180221939A1 | 2018-08-09 | Daisuke YAMASHITA; Hirotsune WATANABE; Masashi MORIKAWA |
| A method of reusing core sand includes crushing a core used for casting into granules; heating the granules at a temperature of 300° C. to 550° C.; causing the heated granules to collide against each other such that water glass used as a binder detaches from the core sand; and blowing air into a mixture of the water glass and the core sand, which are detached from each other, such that the core sand is separated and collected from the mixture due to a difference in specific gravity between the water glass and the core sand. | ||||||

| Molding sand of a used greensand mold is recycled by adding water and binder to sand particles fatigued by heating applied by a molten metal during molding and segregated from vigorous molding sand not directly heated by the molten metal and mixing the refreshed molding sand particles with the vigorous molding sand. | ||||||
| 193 | Method of regenerating used foundry sands | US838831 | 1992-02-21 | US5259434A | 1993-11-09 | Bernd Federhen |
| 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. | ||||||
| 194 | 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. | ||||||

| Apparatus for reducing lumps of material, such as lumps of sand recovered from casting operations in metal foundries or lumps of ore and the like, including various forms of bonded abrasive grinding wheels for abrading the lumps and reducing them to particle or granular form. | ||||||
| 196 | Jaw crushers | US558164 | 1975-03-13 | US3976255A | 1976-08-24 | Albert Edwards |
| A jaw crusher is provided with a pressure relieving system to allow a movable jaw of the crusher to yield in case of an excess crushing load. The movable jaw is urged outwardly by a spring and an hydraulic ram exerts inward pressure on the jaw against the spring action. The ram has a control system for reducing the ram pressure when an excess load is encountered allowing the spring to move the jaw outwardly and after a suitable time delay for re-establishing the pressure within the ram to return the jaw to its inner position against the spring action. | ||||||
| 197 | Foundry mixing machine | US41694873 | 1973-11-19 | US3881703A | 1975-05-06 | REBISH EDWARD JOHN |
| A foundry mixing machine is disclosed for mixing a mold material component with a binder component comprising a mixer for dispersing the binder component into a dispersion and provisions for establishing a flow of the mold material component to traverse the dispersion a plurality of times to enable a complete mixing of the mold material and binder components. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

| 198 | Ball mill for treating used casting sand | US35698473 | 1973-05-03 | US3862719A | 1975-01-28 | MULLER KARL A |
| A ball mill for treating and washing used casting sand has a drum that includes an interior and exterior wall. The space between these interior and exterior walls form an intermediate chamber. Disposed along the exterior wall is a screen through which passes the treated sand. The drum may be positioned on an inclination with repect to the horizontal and has contained within its interior a plurality of mill balls. Feeding means are placed at, and comprise one end of the drum. The feeding means are placed so as to be concentric about the central longitudinal axis of the drum. Means are placed within the intermediate chamber to subdivide it into compartments. A continuously operating discharge means is disposed at, and comprises the other end of the drum so that the metallic residue of the casting sand migrates towards the discharge means and exits thereat as the drum revolves.

| This invention relates to an improved device for conditioning foundry sand or the like, comprising primarily a smooth surfaced drum support, tightly enclosed by a belt which carries a plurality of outwardly extending tool elements fastened thereto. The belt and tools associated therewith may be readily and quickly removed and replaced as a unit, whereby changing from one set of tools to another, or from a set of worn tools to a set of new tools is greatly facilitated. The novel device is readily associated and employed with conventional foundry conveyor belts used to transport sand.
