Patent number: 4038021Abstract: My continuous drier comprises an inclined tubular casing having a feed tube concentrically disposed therein via which the product, such as grain or seed, to be dried is delivered to the lower end of the casing. Circumscribed about the feed tube and in a fixed relation thereto is an auger having its peripheral edge secured to the interior of the tubular casing. Most of the flights of the auger are perforated, the holes being of a size sufficiently small so that the granular product will not pass therethrough, yet large enough to allow a heat conductive media, such as salt particles, to sift downwardly as the drier is rotated about its inclined axis. Whereas most of the auger is perforated, two flights adjacent the closed lower end of the casing are imperforate.Type: GrantFiled: April 5, 1976Date of Patent: July 26, 1977Inventor: John O. Benson

Patent number: 4021195Abstract: A planetary cooler system is disclosed for cooling hot pulverous or granular material produced and exited from the discharge end of an inclined rotary drum such as a rotary kiln. A plurality of cooler tubes are mounted in planetary fashion about the material discharge end of the kiln with the axis of each tube in parallel, or approximately parallel, relation to the axis of the drum. A conduit communicates the discharge portion of the rotary drum with each cooler tube for the passage of hot material therethrough in countercurrent to preheated cooling air passing from the cooler tube to the drum to serve as combustion air. The conduit is so positioned as to divide each cooler into at least two sections, a first section of the cooler tube extending away from the conduit in a direction generally upstream of the flow of material inside the kiln, and the second section extending away from the conduit in a direction generally downstream of the flow of material in the kiln.Type: GrantFiled: March 15, 1976Date of Patent: May 3, 1977Assignee: F.

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.
