Patent number: 10464072Abstract: The invention relates to a method and an apparatus for comminuting grinding stock with a roller mill, wherein a grinding plate cooperates with at least two grinding rollers and the grinding stock supplied in the mass flow is comminuted between grinding plate and grinding roller. At least two grinding rollers are driven via dedicated drives, wherein a power compensation control is carried out for the drives of the grinding rollers, such that the power of the drives is controlled in a predefined ratio to one another. The power control is then effected by changing the mass flow of the grinding stock supplied to at least one of the grinding rollers.Type: GrantFiled: July 3, 2013Date of Patent: November 5, 2019Assignee: THYSSENKRUPP INDUSTRIAL SOLUTIONS AGInventors: Pedro Guerrero Palma, Ludwig Könning

Patent number: 9915595Abstract: A method for operating a gas sampling probe includes removing a gas to be analyzed from a process space in the region of a front end of a gas sampling tube and conducting it through the gas sampling tube as far as a rear end and, in the process, cooling it by passing cooling air between the gas sampling tube and at least one outer casing enclosing the gas sampling tube. The cooling air is fed and discharged at the rear end of the gas sampling tube and the temperature of the gas to be analyzed is higher in the region of the front end of the gas sampling tube than the temperature of the fed cooling air, and the gas sampling probe emits outward, wherein the temperature of the fed cooling air is higher than the temperature of the discharged cooling air.Type: GrantFiled: July 31, 2014Date of Patent: March 13, 2018Assignee: THYSSENKRUPP INDUSTRIAL SOLUTIONS AGInventors: Ludwig Könning, Michael Streffing, Heinz Bredemeier, Alfons Leuer

Patent number: 8833686Abstract: A roller mill for comminuting brittle grinding stock comprises at least one grinding roller constructed as a loose roller and rotatable about an axis and interacting with a counter-surface such that grinding stock is comminuted between the grinding roller and counter-surface. Horizontally slidable bearing blocks bear the grinding roller and are guided in a frame rotatably about a vertical bearing axis. A pressing device applies an adjustable grinding pressure to the grinding roller via the bearing blocks. At least two resilient compensation elements are associated with each bearing block in order to compensate a skewed position and/or deflection of the grinding roller. The compensation elements are arranged between the frame and the bearing blocks, and, in the plan view of the roller mill, are arranged tangentially to a circle around the vertical bearing axis or constructed in a circular arc around the vertical bearing axis.Type: GrantFiled: October 10, 2011Date of Patent: September 16, 2014Assignee: ThyssenKrupp Polysius AGInventors: Thomas Rüther, Alexander Peters, Ludwig Könning, Nils Hörster, Reinhard Giesemann
