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.
Design of portable station, case type, with replaceable bases for measuring the surface wear of the mill grinding table and rolls.
