Publication number: 20230182146Abstract: A method for starting a grinding tube with an assigned drive device, wherein during the operation of the grinding tube a grinding mode and a charge release mode can be set such that a particularly reliable monitoring of the state of charge located in the grinding tube is ensured, where the grinding tube is rotated and, at a first rotational angle, a first actual torque is detected, a setpoint torque is calculated for a second, relatively large rotational angle based on the first actual torque, an actually occurring, second actual torque is detected when the second rotational angle is reached, an investigation is performed to determine the difference of the second actual torque from the setpoint torque, and the charge release mode of the grinding tube is set when the second actual torque is within the threshold range, otherwise the grinding tube is operated in the grinding mode.Type: ApplicationFiled: May 23, 2017Publication date: June 15, 2023Inventors: Adem KARADENIZ, Stefan SMITH, Kurt TISCHLER

Publication number: 20220335345Abstract: A method, device, and system for managing a mining facility including a plurality of systems. The method includes generating, on a simulation unit, system models for one or more systems from the plurality of systems of the mining facility. The system models are generated based on one of input signal, sensor data and output signal from the plurality of systems at the mining facility. The method further includes generating a facility model of the mining facility based on dependencies between the system models and managing the mining facility by simulating operation of the mining facility using the facility model.Type: ApplicationFiled: September 4, 2020Publication date: October 20, 2022Inventors: Jorge Alejandro Oyarzun Gonzalez, Joachim Schneider, Stefan Smits, Kurt Tischler

Patent number: 10967383Abstract: In a method for detaching a frozen charge from an inner wall of a grinding tube of a tube mill, a motor of a drive system is operated in a first mode to rotate the grinding tube for grinding. In a second mode, the motor of the drive system is operated to remove the frozen charge from the inner wall of the grinding tube such that operation of the motor to effect a rotational movement of the grinding tube is repeatedly disturbed by a disturbance signal to cause a repeated disturbance within a variable time interval, with the time interval of the repeated disturbance being shortened.Type: GrantFiled: August 22, 2018Date of Patent: April 6, 2021Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Dan Niculae Fodor, Andreas Procksch, Kurt Tischler

Patent number: 8366029Abstract: The method is used to determine the filling level of a loaded mill container (2). The container (2) has a drive torque (M) applied to it by means of a drive (6), and causes it to rotate. The drive torque (M) on the drive (6) is set by means of a predeterminable drive test sequence. A time/rotation speed profile of a rotation speed of the container (2) which results from the drive test sequence is recorded, and is analyzed. The filling level is determined on the basis of the results of the analysis. The method produces up to date, accurate information, determined during the milling operation, about the filling level of the container (2).Type: GrantFiled: June 19, 2007Date of Patent: February 5, 2013Assignee: Siemens AktiengesellschaftInventors: Norbert Becker, Hans-Ulrich Löffler, Stefan Smits, Kurt Tischler

Patent number: 8276837Abstract: In a method for detaching a charge (5) which is stuck to the inner wall of a grinding pipe (1), the grinding pipe (1) is rotated in a targeted manner such that the charge (5) that is stuck is removed from the inner wall of the grinding pipe (1) as a result of multiple modification of the rotational speed of the grinding pipe (1) and, optionally, as a result of abrupt braking of the grinding pipe (1). Generally speaking, the material-dependent maximum angle of rotation F of the grinding pipe is not exceeded in order to avoid the charge that is stuck from falling in an uncontrolled manner. The invention supercedes labor-intensive and protracted methods for detaching such charges (5) since the tasks can be carried out by the same motor of the drive device (2) which is used to drive the grinding pipe (1) during the grinding process.Type: GrantFiled: August 2, 2011Date of Patent: October 2, 2012Assignee: Siemens AktiengesellschaftInventors: Norbert Becker, Stefan Smits, Kurt Tischler
