Definitions
- the invention relates to a roller mill with a rotatable around a rotation axis grinding table, at least one grinding roller, which is in rolling engagement with the grinding table and a main drive for driving the grinding table.
- the grinding tables are driven by vertical roller mill by means of an unregulated asynchronous or synchronous motor and a multi-stage gearbox.
- very large torque fluctuations occur, which are caused by the grinding process.
- a roller mill is known for example from DE 36 33 747 Al.
- DE 36 40 146 Al a planetary differential gear with a main and an auxiliary drive shaft for generating adjustable speeds is described. Additional gear elements can be used to engage and disengage power transmitting connection between the two drive shafts are made.
- DE 35 45 314 C2 discloses a transmission for conveying, extraction, - or crushing plants with at least one Umlaufstirnradform as the output stage and connected to the engine gear input stage. A torque measuring device monitors the torque. When an adjustable maximum torque is exceeded, the prime mover is switched off.
- the invention is an object of the invention to provide a roller mill and a method for operating the roller mill, wherein torque fluctuations of the drive or speed fluctuations of the
- Mahltellers be steamed.
- roller mill according to the invention essentially consists of one around one
- Rotary axis rotatable grinding table at least one grinding roller, which is in rolling engagement with the grinding table and a main drive for driving the grinding plate.
- an auxiliary drive for driving the grinding table and a control device is provided, wherein the control device comprises at least one damping controller, the auxiliary drive in dependence on
- the main drive comprises a planetary gear with sun gear, planetary gears and ring gear, wherein the ring gear is rotatably arranged and the auxiliary drive is provided for driving the ring gear.
- the control device, the auxiliary drive in dependence of the torque fluctuations of
- the torque of the main drive or the sun gear and / or the rotational speed of the grinding table can be determined and fed as a measured variable of the control device.
- control device comprises a state space controller.
- Fig. 2 is a block diagram of the roller mill with control device.
- the roller mill shown in Fig. 1 consists essentially of a rotatable about a rotation axis 1 grinding table 2, at least one grinding roller 3, 4, with the
- Grinder is in rolling engagement and a main drive 5 for driving the grinding table.
- the main drive 5 comprises a planetary gear with a sun gear 6, a plurality of planetary gears 7, 8 and a ring gear 9.
- the main drive 5 drives the sun gear 6 via a main drive train 10.
- the planet gears 7, 8 are connected via planet carrier 11, 12 with the grinding table 2 such that the grinding table can rotate about the rotation axis 1.
- the axis of rotation 1 is aligned vertically.
- an auxiliary drive 13 is provided for driving the grinding table 2.
- the ring gear 9 of the planetary gear is rotatably mounted and coupled via an auxiliary drive train 14 with the auxiliary drive 13.
- the auxiliary drive 13 is connected to a control device 15 in conjunction, wherein the
- the control device 15 shown by way of example in FIG. 2 comprises at least one
- Damping controller namely the main damping controller 16 the current torque and a time-averaged torque of the sun gear is supplied.
- the torque of the sun gear is provided, for example, via a suitable sensor 17 or via a state model.
- the main damping controller 16 now calculates the target speed of the auxiliary drive, which changes the transmission ratio of the transmission by its variable speed and thus can counteract torque fluctuations.
- the change in the rotational speed of the auxiliary drive 13 is effected in particular via a frequency converter 18.
- a plate speed controller 19 is provided which receives the desired plate speed as the setpoint and the current plate speed as the actual value.
- the actual speed of the grinding table 2 is made available either via a sensor 20 or a state model. Furthermore, a
- Damping controller 21 are provided for the auxiliary drive to To compensate for torque fluctuations by stimulating the intrinsic behavior of the auxiliary drive.
- the main damping controller 16 and / or the plate speed controller 19 instead of in the classical way as a PID controller, is designed as a state space control. In this case, the parameterization is carried out by Polvorgabe in the image plane.
- the auxiliary drive 13 which drives the ring gear 9 of the planetary gear, is operated via the frequency converter 18 with internal engine and mechanical model 22 and an active engine controller 23. It should expediently be equipped so that the temporarily necessary braking energy can be fed back into the network 24, whereby the efficiency of the overall system compared to the previously known systems can be further improved.
- the auxiliary drive is designed as a classic engine-gearbox combination.
- the main damping controller 16 and the plate speed controller 19 sizes and the resulting correction moments torque oscillations can occur in the auxiliary drive train. These are damped by a sensorless state space control.
- Torques and / or speed fluctuations of the grinding table can be realized with high drive power without the main drive must be operated by means of frequency converter. Also on the side of the auxiliary drive can be dispensed with the use of an active sensorless state control on special drives. As a result, the cost of such a system is significantly lower for large drive powers (> 2 MW) than if the main drive had to be actively influenced.
- the required for the activation of the additional drive 13 torque measurement according to the invention could also have a highly dynamic
- Angle measurement is made because the twist is proportional to the torque with negligible damping.
- the drive power required for driving the grinding table is expediently applied to a proportion of 5 to 30%, preferably 10 to 20%, by the additional drive.
- a significant power reserve must be planned for the frequency converter 18 (2 to 2.5 times the nominal power of the variable speed drive).
