Definitions

  • the invention relates to a method and a plant for the comminution of ground material with a roller mill, wherein a grinding table cooperates with at least two, driven by their own drive grinding rollers and crushed in the mass flow material is comminuted between the grinding table and grinding roller.
  • the compensation control is formed by a power compensation control, wherein the power of the drives is controlled in a predetermined ratio to each other by controlling the speed of at least one drive.
  • a regulation of the grinding pressure is used to regulate the power of the drives in a predetermined relationship to one another.
  • the EP 0 180 814 A2 discloses a roller mill with a control system to operate the mill over a wide flow range, ensuring a satisfactory air-to-solid ratio and degree of fineness.
  • the invention was based on the object to develop a new concept of power balancing.
  • a grinding table cooperates with at least two grinding rollers, whereby the millbase supplied in the mass flow is comminuted between the grinding plate and the grinding roller.
  • At least two grinding rollers are driven by their own drives, whereby a power compensation control for the drives of the grinding rollers is performed, so that the performance of the drives is controlled in a predetermined ratio to each other.
  • the power control is carried out by changing the mass flow of at least one of the grinding rollers supplied grinding material.
  • the inventive plant for the comminution of ground material with a roller mill has a grinding table and at least two cooperating with the grinding table grinding rollers, wherein the mass flow supplied grinding material is comminuted between the grinding table and grinding roller, and wherein at least two grinding rollers have their own drive and a power compensation for the Drives of the grinding rollers for controlling the power of the drives in one predetermined ratio is provided to each other.
  • the power balancing control cooperates with at least one actuator to change the mass flow of at least one of the grinding rollers supplied grinding material.
  • mass flow is understood to mean the mass flow or mass flow which is usually applied centrally via a feed device to the grinding plate and then conducted to the grinding rollers. While the power compensation regulation known from the prior art acts directly on the grinding rollers by regulation of the rotational speed or the grinding pressure, the concept according to the invention for power compensation control proposes influencing the mass flow.
  • the power compensation control preferably uses the torque and / or the speed of the drives as a controlled variable.
  • the change in the mass flow can be effected in particular by influencing the orientation of the mass flow with respect to the grinding roller and / or influencing the width of the mass flow and / or influencing the height of the mass flow and / or influencing the quantity supplied.
  • it can be provided to precompress or loosen up the ground material supplied in the mass flow.
  • the power compensation control device is expediently with torque sensors for detecting the torque of the drives of the grinding rollers and / or with speed sensors for detecting the rotational speed of the drives Grinding rollers in operative connection, then depending on the measurement result, at least one actuator to control the mass flow to control.
  • actuators can be formed for example by guide elements, adjustable chutes, adjustable height limits and metering devices.
  • the drives of the grinding rollers are in particular unregulated three-phase electrical asynchronous motors in question.
  • the performance of the drives can basically be controlled so that the operating torques of the drives are between zero and the overturning moment of the drives. In this way, the drives of the grinding rollers can be adapted to the respective grinding requirements in a wide range.
  • Fig. 1 shown plant for crushing regrind with a roller mill has a grinding table 1 and at least two with the grinding table cooperating grinding rollers 2, 3, wherein the mass flow in a feed device 4 supplied grinding material 5 is comminuted between grinding plate and grinding roller.
  • Each of the two grinding rollers 2, 3 has its own drive 6, 7, while the grinding table in the illustrated embodiment on the grinding rollers 2 and 3 and the material to be ground 5 is driven and thus no own drive is assigned. In the context of the invention, however, the grinding table can also be driven.
  • a power compensation control device 8 is provided, which interacts with measuring members 9, 10 and at least one actuator 11.
  • the measuring members 9, 10 are formed for example by torque sensors for detecting the torque M1, M2 of the drives 6 and 7 and / or by speed sensors for detecting the rotational speed n1, n2 of the drives 6, 7. With the measured values, the power compensation control device 8 can determine the power of the two drives 6, 7.
  • the aim is to divide the total power of all drives in a given ratio to the individual drives. It can be provided, for example, that all drives are operated with the same power. However, it is quite conceivable that the services evaluate differently divided, which may be the case for example with different sized grinding rollers.
  • the power compensation control device regulates the power of the individual drives so that the powers are within a predetermined target range. If it is ascertained via the measured values (rotational speed, torque) that the power of one or the other drive is outside the setpoint range, a targeted influencing of the mass flow of the grinding material 5 supplied to at least one of the grinding rollers 2, 3 is undertaken via the actuator 11. This may, for example, be such that the grinding roller, the drive of which has increased power, is supplied with less material to be ground than the grinding roller, whose drive consumes a power that is too low. In this way, the power of the two drives 6, 7 can be influenced in a targeted manner via the change in the mass flow in order to regulate the power of the two drives in the predetermined ratio of, for example, 50% in each case.
  • drives 6, 7 are equipped with expensive control devices, such as frequency converters.
  • control devices such as frequency converters.
  • three-phase electrical asynchronous motors are used as drives 6, 7.
  • the plant described above is particularly suitable for the comminution of regrind, such as limestone, binder and coal.
  • the roller mill can be designed, for example, as follows: Diameter of the grinding table 1: 2 m to 8 m Diameter of the grinding roller 2, 3: 1 m to 4 m Rated power of the drives 6, 7: 100 kW to 4000 kW
  • the actuator is formed by a provided at the lower end of the task device 4, pivotable chute 11a, which is pivotable via an actuator 11b.
  • the power compensation control device 8 will therefore correspondingly control the actuator 11b as a function of the measured values determined by the measuring members 9, 10 if the powers of the two drives 6, 7 are outside their predetermined control ranges.
  • the actuator is formed by an adjustable guide plate 11c with associated actuator 11b.
  • this baffle 11c in particular, the orientation of the mass flow with respect to the grinding roller and / or the width of the mass flow and / or the amount supplied.
  • Fig. 4 shows the variant in which the mass flow is changed by influencing its height.
  • the actuator is formed by a height limiting element 11e that can be adjusted by an elevation 11f in height by the power compensation control device 8.
  • the mass flow is influenced by changing its composition.
  • the actuator is formed by a metering device 11g with associated actuator 11h, 11g additives are added to the material to be ground via the metering device 11g, such as fresh, circulating or finished good, coal, aggregates, water or grinding aids. If this addition occurs specifically before a grinding roller, the power consumption of the associated drive can be influenced in a targeted manner.
  • each grinding roller can be preceded by a so-called slave roller, which enables a pre-compression of the grinding bed and thus influencing the power consumption of the drives associated grinding roller via a variable contact pressure.
  • a loosening of the grinding bed for example by fluidizing air, is conceivable.
  • the power compensation control described above is on the one hand very effective and considerably cheaper compared to the known from the prior art speed control.
