Patent number: 6000936Abstract: The invention relates to a rotating oven with a horizontal or inclined drum, of which at least the inner part is composed of a fireproof material and which is pivotably mounted around its longitudinal axis. The drum contains a tubular element (1) of a fireproof material which is composed of a succession of each other supporting co-axial rings (2), which element (1) is brought under an axial stress starting from its both extremities (6), in order to obtain a self supporting prestressed entity.Type: GrantFiled: May 26, 1998Date of Patent: December 14, 1999Assignee: Zinchem-BeneluxInventor: Henri Jean-Pierre Joseph Taquet

Patent number: 5733115Abstract: A description is given of a rotary drum, as for example a rotary kiln, which is suspended within a live-ring by means of axially extending brackets which are retained by the live-ring and bearing, at their free ends, against retaining elements fixed to the rotary drum, in such a way that the vertical load of the drum relative to the drum shell is transmitted tangentially to the live-ring. The brackets are evenly distributed over the circumference of the live-ring fixed to its side faces. Hereby, the live-ring can be made with a smooth cylindrical inner face without teeth, which, besides being advantageous from an economic perspective, also makes it possible to use existing live-rings of the migrating type. Further, all parts of the device will be more readily accessible in connection with inspection and maintenance work in that none of the parts are concealed under the live-ring.Type: GrantFiled: November 1, 1996Date of Patent: March 31, 1998Assignee: F.L. Smidth & Co. A/SInventor: J.o slashed.rn Petersen

Patent number: 5415541Abstract: The invention relates to a rotary drum with relatively large dimensions, the shell of which is supported by means of riding rings each on a pair of supporting rollers of a supporting roller stand. For this purpose the rotary drum shell merely bears two riding rings which are attached so as to be fixed against rotation and which are supported on two supporting roller stands of which at least one simultaneously forms the rotary drive arrangement for the rotary drum in the form of a friction drive. This produces a combination of features by means of which the mounting of the rotary drum is statically determinate and can be driven reliably in an extremely simple manner.Type: GrantFiled: April 22, 1993Date of Patent: May 16, 1995Assignee: Krupp Polysius AGInventors: Gerhard Kastingschafer, Herbert Pingel, Johannes auf dem Venne, Bernhard Peterwerth, Reinhard Giesemann

Patent number: 4776788Abstract: A kiln is disclosed which includes an elongated housing formed by a plurality of interconnected longitudinally extending sections each forming an independent housing module. Each housing module has support means for rotatably supporting that housing module independently of any other module and power means for moving the support means of each housing module into contact engagement therewith for compensating for load variations applied to the support means and uniformly distributing the loading forces imposed thereon by the housing modules and their respective contents.Type: GrantFiled: June 22, 1987Date of Patent: October 11, 1988Assignee: M & S Engineering & Manufacturing Co., Inc.Inventor: Zygmunt J.

Patent number: 4171949Abstract: An arrangement is disclosed for supporting a rotary drum such as a rotary kiln resting upon a foundation. The support arrangement includes a weigh beam positioned in a horizontal plane and pivotally supported on the foundation. At least two carrying beams are poitioned in a generally horizontal plane adjacent said weigh beam and each of the carrying beams are pivotally mounted at one end thereof to the foundation and flexibly supported at another end thereof by the weigh beam. A roller for rotatably supporting the rotary drum is supported on the carrying beams by bearings. The support arrangement thereby effects a substantial mechanical equalization of the forces exerted on the roller during the rotation of the drum to warping and twisting of the drum.Type: GrantFiled: August 15, 1977Date of Patent: October 23, 1979Assignee: F. L. Smidth & Co.Inventors: William C. Endersen, Borge Johansen

Patent number: 3966395Abstract: A stand is provided to carry a pressure roller in horizontal engagement with a longitudinal surface of a raceway about a large rotating kiln or other drum, the roller being displaceable in a longitudinal direction to force the raceway to oscillate across its radial support rollers, thereby to increase the life of the raceway under wear from concentrated mechanical support stresses. An hydraulic cylinder selectively displaces the roller by acting on a frame on or in which the pressure roller is carried.Type: GrantFiled: November 8, 1974Date of Patent: June 29, 1976Assignee: Klockner-Humboldt-Deutz AktiengesellschaftInventors: Heinrich Schneider, Ernst Boser
