Definitions

  • the invention is directed to a measuring device for measuring the wear of the grinding rollers of two-roller machines, in particular of high-pressure roller presses for pressure comminution of granular material.
  • the nature of the surface of the grinding rollers is important, since, for example, the drawing-in behavior of the ground material largely depends on the surface quality of the grinding rollers, and on the drawing-in behavior the throughput of ground material and the size reduction progress, so that the surface properties of the grinding rollers are also for these reasons is to be monitored.
  • the usual visual assessment of the surface condition is made more difficult by the fast speed of the grinding rollers, so that an assessment can usually only be made when the grinding rollers are at a standstill.
  • the grinding roller is often also covered with adhering regrind, in particular if voids have formed in the surface due to surface detachments, which also makes a reliable assessment more difficult.
  • a measuring arrangement is known, which is arranged laterally next to a roller of a two-roll machine (perpendicular to the material flow direction) to the gap width between the two rolls during the operation of the two-roll machine without contact Taking into account the wear of the rollers. Own movements of the grinding roller, which affect a change in the roller gap, are recorded at the same time. In addition, adhering regrind, which reduces the nip, also adversely affects the wear pattern resulting from the known measuring arrangement.
  • the object of the invention is to provide a measuring device which detects the mechanical depth of wear on the roller surface, reliably indicates this and which is able to carry out the measurement during the operation of the two-roller machine and does not produce the measured value obtained in the regrind adhering to the grinding rollers adulterated.
  • the measurement is expediently carried out from above at the apex line of the grinding rollers, since self-movements of the grinding roller which occur in this way, for example due to misalignment, cannot exert influences which distort the measured value.
  • the measurement signal is formed by an inductive displacement sensor which is responsive to the contactless approach of metal and which is arranged displaceably over the entire roller length above the grinding roller.
  • an inductive displacement sensor which is responsive to the contactless approach of metal and which is arranged displaceably over the entire roller length above the grinding roller.
  • a section parallel to the roller axis of a grinding roller (1) is shown rotatably mounted in a press frame (2).
  • the sensor (3) Above the grinding roller (1) is the sensor (3), which is connected to the press frame (2) so that it can move in the direction of the arrow.
  • both elevations (4) which are applied to the grinding roller surface to improve the feeding behavior of the material to be ground, and local depressions (5), which are caused by surface detachments are detected.
  • the measurement signal is formed only by the distance between the transducer and the metal of the grinding roller, regrind that adheres to the grinding roller or fills the depressions (5), insofar as it cannot be magnetized, is not taken into account in the formation of the measuring signal.
  • the measurement signal also occurs when the grinding roller surface is not accessible to a visual assessment.
  • the measurement signal obtained with the transducer can be routed to any location, for example the control center of the two-roll machine, and can be registered there and / or optically displayed, for example by means of light-emitting diodes, and / or displayed as an acoustic signal .
