Device and Method for tightening Nuts and Bolts that attach the lining The Wall of the Drum of a Mill grinding of Minerals.

摘要

p The present Invention relates to a method and a device with hydraulic systems that allow Measuring the distance between the Outer surface of the Coating and the Inner surface of a MillThe Drum of a Mill and, simultaneously, the stress existing in each pin Mill.According to the values of the apparatus, it is possible to determine the distances and reduce excess stressOffset press or by reducing the distance between the Coating and the Inner surface of the Drum Mill, placing lainas, washers or Supplies,So the nuts are tightened with a torque balanced. / p
