Portable station for measuring surface wear of the grinding table and rolls of the vertical mill for cement grinding

Basic equipment

  • Main frame with driving slideway with a shift of approx. 1300 mm
  • Laser distance sensor
  • Removable digital protractor
  • Replaceable stands - 2 pcs:
    • for grinding table - 1 pc
    • for rolls - 1 pc
  • Stands with the option of inclination angle adjustment of the sensor in relation to measured surface (height adjustment of one of the stand legs)
  • Instrument case of approx. 1500 x 800 x 500 mm size
  • Electrical control box with PLC inside the case
  • Carrier handles.

Instrument assembly

  • For grinding table measurement - in the fixed base on one side, gravitationally inside the grinding table on the other side; fixed base welded to the grinding mill structure in front of inspection point
  • For roll measurement - in the fixed bases on one side, gravitationally on the roll frame; fixed bases with the use of threaded holes for the sleeves mounted on the roll surface area.

Measurement procedure

  • Setting the appropriate inclination angle of the sensor in relation to the surface measured by means of magnetic digital protractor
  • Laser distance sensor performing spot measurement along the cross-section of the working surface of grinding table and roll
  • Uploading measurement results to the data carrier (SD card or pendrive)
  • Possibility of measuring working surface of the grinding table in four points (every 90 degrees or to be decided following order receipt), mechanical rotation of the grinding table
  • Possibility of measuring working surface of the rolls in four points (every 90 degrees or to be decided following order receipt), manual rotation of the roll
  • Measurement results readout every 10 mm or to be determined.
