Patent number: 6036483Abstract: Method of controlling the conveying speed of a grate cooler as a function of the state of the bed of material to be cooled in the initial region of the cooler while taking into account the flow resistance of said bed of material. According to the invention, the conveying speed, in addition to being controlled as a function of the flow resistance, is also controlled as a function of the height of the bed of material to be cooled.Type: GrantFiled: March 18, 1999Date of Patent: March 14, 2000Assignee: BMH Claudius Peters AktiengesellschaftInventors: Hartmut Meyer, Jurgen Cordes

Patent number: 5615987Abstract: Worm conveyor for bulk material, the outlet of which is separated from an outlet chamber, in which a higher gas pressure obtains than at the inlet of the worm conveyor, by a non-return flap, which is pressed by a flexible force into the closed setting. The operating behaviour of the conveyor is improved, in particular drive power and wear are reduced, in that a damper is provided for damping the movement of the non-return flap, in particular for damping the opening movement.Type: GrantFiled: October 5, 1994Date of Patent: April 1, 1997Assignee: Claudius Peters AktiengesellschaftInventor: Hans-Joachim Weist

Patent number: 5586660Abstract: The screening of a stream of bulk material is accelerated so that this takes place in the state of the fluidized bed. The screening apparatus can be made correspondingly smaller. So that the fluidized-bed state persists over the screen surface, the latter is made short and, if necessary, a plurality of screen surfaces with interposed aerating stages are connected in succession.Type: GrantFiled: January 6, 1995Date of Patent: December 24, 1996Assignee: Claudius Peters AktiengesellschaftInventor: Adolf Buchfink

Patent number: 5580005Abstract: Arrangement for crushing and cooling the material passing out of a firing oven, wherein the crusher is arranged in the hot region, preferably immediately following the oven, in the path of the material upstream of the cooler. According to the invention the crusher comprises a plurality of roll-like crushing elements which are mounted overhung and which project into the path of the material from outside said path and for maintenance purposes are retractable therefrom.Type: GrantFiled: November 15, 1994Date of Patent: December 3, 1996Assignee: Claudius Peters AktiengesellschaftInventors: Hartmut Meyer, Gunther Koeberer

Patent number: 5575406Abstract: A bulk-material silo has a silo draw-off opening which is located centrally in the ventilated silo base and is connected directly to an expansion chamber. The expansion chamber comprises two parts, the first of which leads outwardly in the manner of a duct from the silo draw-off opening towards and merging with the second part of the expansion chamber which is arranged outside the actual silo. Only said second part is configured with a sufficient height to permit the bulk material to fully expand during fluidization and with dust-extraction and draw-off devices. The air-extraction line from the upper silo space is fed, outside the silo, directly to the dust-extraction device.Type: GrantFiled: January 9, 1995Date of Patent: November 19, 1996Assignee: Claudius Peters AktiengesellschaftInventor: Adolf Buchfink

Patent number: 5462237Abstract: A jaw crusher is positioned within a duct connecting a high temperature furnace outlet and a cooler for crushing high temperature cement clinker material discharged by the furnace. The jaws are provided with cooling air-swept ducts that extend through the jaws and into the crushing chamber. The working surfaces of the jaws are provided with imbricated protective elements. A stationary jaw member within the duct provides a partition forming an air flow duct portion and a movable jaw member cooperates with the stationary jaw member to delineate a discharge crushing chamber separated from the air flow duct portion. The movable jaw is positioned at the wall of the duct for easy access while the drive mechanism for the movable jaw is located outside the duct.Type: GrantFiled: December 3, 1993Date of Patent: October 31, 1995Assignee: Claudius Peters AktiengesellschaftInventor: Hans-Peter Wellmann

Patent number: 5415512Abstract: A device for loading bulk material from a stationary source to a filler pipe located at a chosen spot within a predetermined line of travel. The device comprises a loading hopper which is shiftable along the line of travel and exhibits, at its lower end, a filling mechanism and a conveying pipe, feeding the bulk material to the loading hopper, which conveying pipe is pivotably mounted at its end receiving the material and the outlet end of which opens out into the loading hopper. The loading hopper is closed off at the top by a cover, which exhibits an opening receiving the outlet end of the conveying pipe. The cover is rotatable in relation to the loading hopper, the opening being eccentrically disposed. Expediently, the rim of the loading hopper and the cover are circular.Type: GrantFiled: April 6, 1993Date of Patent: May 16, 1995Assignee: Claudius Peters AktiengesellschaftInventor: Adolf Buchfink

Patent number: 5224312Abstract: The bulk material silo has a venting bottom containing a fiber layer (4). To compensate the difference in flow-off resistance, which differs with the distance of material from the discharge (6), it is provided that the fiber layer differs in flow resistance (10) along the path of the material toward the outlet (6), specifically having a lower flow resistance in regions further away from the outlet.Type: GrantFiled: July 1, 1991Date of Patent: July 6, 1993Assignee: Claudius Peters AktiengesellschaftInventor: Adolf Buchfink

Patent number: 4606158Abstract: Double silo with an inner silo part and an outer silo part which surrounds it annularly. A central mixing chamber for the material emanating from the inner silo area and an annular mixing chamber for the material emanating from the outer silo area are located within the silo dividing wall separating the two silo parts and at the bottom in the inner silo part.Type: GrantFiled: September 11, 1984Date of Patent: August 19, 1986Assignee: Claudius Peters AktiengesellschaftInventor: Werner Krauss
