| 25 | Method of and device for continuous preparation of granular material, such as foundry sand | US3712593D | 1971-03-23 | US3712593A | 1973-01-23 | SZATMARI F |
| A method and device for mixing, loosening, aerating and cooling granular material is disclosed where the material to be treated is introduced into two axially arranged cylindrical containers spaced at a small distance one from another to provide a discharging gap therebetween. At least one of the containers is rotated by a driving motor so that the contacting grain layers in the gap will rub together and subsequently are discharged by centrifugal forces from the gap.

| To provide an apparatus for reclaiming foundry sand and a method for reclaiming foundry sand that can effectively remove binders and so on that attach to returned foundry sand that has been used. Foundry sand that has been used is supplied from a chute for feeding sand 14A to a rotor 16. The rotor 16 is rotated by a driver 20 so that frictional force is generated on the sand in the rotor 16. Then, the sand in the rotor 16 is dropped into the container for washing with water 30 that is located below the rotor 16. In the container for washing with water 30, an agitator 34 is rotated by the driver 20 so that the sand in the container for washing with water 30 is agitated and washed with water. | ||||||

| A method includes measuring a water content and a magnetized matter content of molding sand discharged from green sand casting equipment; comparing the measured water content with a first control value, and if the water content exceeds the first control value, drying the molding sand until the water content becomes equal to or less than the first control value; comparing the measured magnetized matter content with a second control value, and if the magnetized matter content exceeds the second control value, magnetically separating the molding sand until the magnetized matter content becomes equal to or less than the second control value; thereafter, reclaiming the molding sand by dry mechanical reclamation until a loss-on-ignition becomes equal to or less than a third control value; and classifying the molding sand until a total clay content becomes equal to or less than a fourth control value. | ||||||

| 35 | Apparatus for mixing particulate material in a liquid | US776696 | 1977-03-11 | US4106117A | 1978-08-08 | Henry R. Cloots |
| A mixing bowl having an outwardly flared inner surface is rotated around its axis at a speed which is great enough to cause a film of liquid within the bowl to be moved upwardly by centrifugal force to the rim of the bowl. A liquid is introduced into the bottom of the bowl at a rate that permits an unbroken film of liquid to form within the bowl and move from the bottom to the rim. Particulate material is uniformly distributed in a radial direction within the bowl to contact the liquid film and mix therewith. The rim of the bowl is shaped to interact with an adjacent stationary surface to shear the liquid and particulate material mixture to increase the uniformity of the mixture. A basin is positioned around and under the rim of the mixing bowl to collect the mixture as it is thrown off the outer edge of the rim. | ||||||
