Patent number: 4933073Abstract: A rotating drum (1) for cooling and separating castings and molding sand has a foraminous liner (27, 8). In a first part (28) thereof there are sand raising vanes (17) between this liner (27) and the closed wall (28) of the drum to raise sand, passing through the perforations in this liner part (28) to spray it over the castings. In a second, more downstream part (8) of the liner this liner part (8) intersects the theoretical sand level (13, 14) to lift the castings from the sand, so as to discharge the castings via liner part (9) and discharge edge (10) separately from the sand. The sand separated from the castings is taken up in a closed end part (5, 7) of the drum (1) having a discrete discharge edge (11) for discharging the sand at the downstream end in a narrow zone. This gives a drum with high cooling and separating capacity and efficiency with the least possible noise and dust generation.Type: GrantFiled: December 20, 1988Date of Patent: June 12, 1990Inventors: Cornelis O.

Patent number: 4031354Abstract: A rotary inclined tubular drier for puffing or expanding borax and a process for the production of puffed or expanded borax beads of desired physical characteristics. A rotatable tube is mounted on bearing wheels and surrounded by a fixed, close-fitting, insulated tube having electrical heating elements running lengthwise attached to its inside wall. The rotatable tube is fed continuously with granular borax feedstock by a vibratory feeder from its higher end and the puffed borax is discharged into a discharge chute from the lower end of the tube. A counter current of dry air is maintained by a suction hood at the high end of the tube, and borax is prevented from adhering to the interior of the tube by an adjustable, spring-loaded, internal scraper. The temperature of the drier is controlled by means of a pyrometer incorporated into a scraper support rod on the interior of the tube.Type: GrantFiled: October 9, 1975Date of Patent: June 21, 1977Assignee: Canada Packers LimitedInventor: Godfrey B.

Patent number: 4014106Abstract: A dryer for removing moisture from wet fine particles, such as coal, comprising an insulated stationary cylinder in which an open-ended metallic cylindrical tube is rotated, coaxially in an essentially horizontal position. Wet particles are introduced in said open end while hot air is circulated between the stationary cylinder and the tube. Metallic balls or the like contained in the rotating tube are interspersed in the wet mix. Perforated fins and baffles extend from the outer wall of the tube to aid in transferring heat, by conduction, to the tube and metallic balls to evaporate the moisture before the coal is discharged at the opposite end through a screen section of the tube. Additives may be introduced into the wet mix to coat the dried coal particles to prevent dust or prepare the mix for pelletizing or briquetting.Type: GrantFiled: June 20, 1975Date of Patent: March 29, 1977Inventor: Wendell E.
