Patent number: 10137478Abstract: A classifier for classifying granular feedstock has a rotary cage rotating about a rotor axis and an air-guiding system arranged around the rotary cage, wherein a classifying zone is formed between the rotary cage and the air-guiding system. In the classifying zone one or more baffles are arranged such that the torque acting on the rotary cage is increased—for the same rotational speed—by at least 20% with respect to an embodiment without baffles and/or the separation between the air-guiding system and the rotary cage is chosen such that the torque acting on the rotary cage is increased—for the same rotational speed—by at least 20% with respect to an embodiment wherein the separation of the air-guiding system is without influence on the torque of the rotary cage.Type: GrantFiled: February 10, 2014Date of Patent: November 27, 2018Assignee: THYSSENKRUPP INDUSTRIAL SOLUTIONS AGInventors: Olaf Hagemeier, Karsten Melies, Matthias Wuwer, Ludger Schulte

Patent number: 8735790Abstract: A microscope for examining an object includes a laser light source generating pulsed light so as to illuminate the object. A measuring system including a detector is adapted to detect detection light coming from the object and the measuring system generates a measurement signal based on the detection light. The microscope includes a programmable integrated circuit including a control element and at least one of a first delay element and a second delay element. The control element is configured to generate a first control signal adapted to control the detector and the measuring system. The control element is further configured to generate a second control signal adapted to control the laser light source. The first and second delay elements are configured to delay the first and second control signals, respectively.Type: GrantFiled: November 25, 2010Date of Patent: May 27, 2014Assignee: Leica Microsystems CMS GmbHInventors: Ludger Schulte, Bernd Widzgowski

Patent number: 7971815Abstract: A milling station and a method for grinding milling material using at least one coarse grinding circuit and at least one fine grinding circuit. The coarse grinding circuit includes a classifier and a material bed roller mill. The fine grinding circuit includes a tube mill with at least two grinding chambers, a central outlet, and a divider. In some instances, at least some of the milling material from the coarse grinding circuit is subdivided in the divider and delivered to the at least two grinding chambers of the fine grinding circuit while some of the milling material is jointly discharged from the at least two grinding chambers through the central outlet.Type: GrantFiled: February 14, 2006Date of Patent: July 5, 2011Assignee: Polysius AGInventors: Ludger Schulte, Franz-Josef Zurhove, Donald A. Longhurst

Publication number: 20090020636Abstract: The invention relates to a milling station and a method for grinding milling material by means of at least one coarse grinding circuit (1) and at least one fine grinding circuit (2). The coarse grinding circuit is provided with a classifier (10) and a material bed roller mill (11). The precrushed material of the material bed roller mill is fed to the classifier whose coarse material is redirected to the material bed roller mill and whose fine material is delivered to the fine grinding circuit. The fine grinding circuit encompasses a tube mill (20) with at least two grinding chambers (20a, 20b), a central outlet (20c), and a divider (21). At least some of the milling material of the coarse grinding circuit is subdivided in the divider and is delivered to the two grinding chambers while the milling material is jointly discharged from the two grinding chambers via the central outlet.Type: ApplicationFiled: February 14, 2006Publication date: January 22, 2009Inventors: Ludger Schulte, Franz-Josef Zurhove, Donald A.

Patent number: 7168645Abstract: A lifting wall for a tube mill which has a discharge means with lifting vanes in order to transport the material being ground to discharge openings by the rotary movement of the tube mill. The lifting vanes are disposed obliquely with respect to the radial direction so that the material being ground slides promptly to the center where it is discharged through the discharge openings still below the horizontal longitudinal central plane of the tube mill. The lifting vanes are substantially flat and bent like blades in a region of the discharge openings.Type: GrantFiled: June 4, 2002Date of Patent: January 30, 2007Assignee: Polysius AGInventors: Gerhard Blatton, Hubert Grothaus, Ludger Schulte

Patent number: 7073737Abstract: The invention relates to a rotary tube mill and to a method of comminuting lumpy mill feed material, in which at least a first and a second grinding chamber as well as a co-rotating partition disposed between the grinding chambers are used. The material ground in the first grinding chamber is divided in the partition into first and second part-quantities of mill feed material, whereby at least a part of the second part-quantity of mill feed material proceeds into the second grinding chamber and at least the first part-quantity of the mill feed material is discharged separately from the tube mill.Type: GrantFiled: November 28, 2002Date of Patent: July 11, 2006Assignee: Polysius AGInventors: Ludger Schulte, Frank Ungethüm, Robert Schnatz, Thomas Rüther, Ludwig Könning, Jens Reimers, Hubert Eickholt, Dirk Dilly, Heinz Alker, Reinhard Giesemann

Patent number: 5791490Abstract: The invention relates to a separator comprising a separator housing with an inlet spiral for separating air which opens tangentially into an annular separating chamber and is divided into a plurality of delivery channels which lie one above the other, as well as a basket-shaped separator rotor disposed centrally and with a vertical axis in the separator housing and a guide vane ring which surrounds the latter with a radial clearance. In order that this separator on the one hand has a high effectiveness of separation between oversize material and fine material and on the other hand facilitates a sufficiently broad grain size distribution of the fine material, the overall shape of the separator rotor is that of a cone which tapers downwards.Type: GrantFiled: January 7, 1997Date of Patent: August 11, 1998Assignee: Krupp Polysius AGInventors: Otto Heinemann, Ingo Engeln, Hubert Eickholt, Ludger Lohnherr, Michael von Seebach, Ludger Schulte
