Abstract: A method is shown for removing minute traces of thermally fused foundry bonding clays from foundry sands reclaimed by a thermal sand reclaimer. The sand grains are passed to a dual fluid bed sand cooler-scrubber having sparge tubes for fluidizing air distribution, finned water cooling tubes and baffle plates for directing sand travel across the tube banks. The fluidized bed extends under a series of dry scrubber cells where the sand grains are hurled through blast tubes toward target plates by blast nozzles. Air current created within the interior of the device creates a controlled negative atmosphere which carries off unwanted traces of oxides and clays, as well as unwanted fine sand grains. The sand grains which are suitable for reuse are captured and deflected into a discharge section of the fluid bed where they flow over a weir by gravity and are discharged for re-use.

Abstract: A process and device for crushing bulk materials. The material to be crushed is fed from above to a first accelerating device which accelerates it into a first crusher, the fine particles in the crushed material produced by the first crusher being carried upwards by an air or gas stream. The larger particles trickle downwards and are then carried by an air or gas stream vertically upwards to another accelerating device which accelerates them into another crusher. The fine particles produced in the second crusher are swept upwards by the air or gas stream, while the larger particles trickle downwards and are brought round to the beginning of the cycle again. The invention concerns the combination of a vertical impact crusher with a separator, both of which are preferably located inside the same housing.

Abstract: A milling system for cereal grains such as wheat includes one or more bran removal machines which removes a substantial fraction of the bran of the incoming wheat to form a pearled wheat. The pearled wheat is then supplied as a feed stock to a disc mill in the first break position. The bran removal machines preferably include inner and outer abrasive elements, wherein the outer abrasive elements extend over a cumulative arc of at least about 250 degrees. Because a substantial portion of the bran is removed prior to the first break position, prior art problems associated with bran fragmentation in a disc mill are reduced.

Abstract: An apparatus shreds hazardous waste drums and their contents in an oxygen-limited environment, transports the shredded material to a dispenser that dispenses metered amounts of the material into fire pails. The apparatus has two vertically separated shredders that are located in an enclosed shell that has an inert gas fed into it in a controlled manner by a purge system. A lift in an enclosed shaft raises the drums, two at a time, and deposits them into an airlock from which they are released one at a time into the upper shredder. A control system automatically processes the material through the apparatus from when the containers are placed into the lift until the material reaches the dispenser and insures that no stage of the process will commence until the proceeding and following stages are completed. The control system also provides safety checks at each stage to prevent handling or processing accidents.

Abstract: A planetary mill adapted for the continuous grinding of granulated material into fine powder is disclosed. A grinding chamber is provided that is continuously orbited in a planetary motion. As the tube undergoes its planetary motion it is caused to undergo a rotation about its own axis at the same rate and in an opposite sense to the planetary rotation. As a result the grinding chamber has no net rotation with respect to an external observer and can be connected to any number of external connections without the use of rotating seals provided the drive for the planetary rotation is external to the locus of points encompassed by the path of the connections as the system rotates. The ratio of the orbit radius of the planetary motion is 2.15 times that of the cylindrical tube so as to cause a cascade angle of about 45 degrees of mill mix and media in the orbiting tube which angle is independent of the rotation rate of the mill at reasonable speeds.

Abstract: The present invention relates to a device for protecting refining discs from excessive mechanical wear by preventing unwanted debris from coming between the discs.
