Diagrams of the Pressure Distribution in the Gap
|
|
|
|
|
|
The pressure sensor in the roller is used to measure the pressure distribution in circumferential direction. The resulting
pressure diagrams are shown below. The granular structure of the material bed causes that the pressure diagrams are not showing a smooth curve but a curve with statistcal variations. This effect
increases with increasing particle size and decreasing grinding force.
The following links will lead you to some typical examples for pressure diagrams at a roller speed of u = 0.3 m/s and a
normalized axial coordinate l = 0.19:
For further discussions the average curves of 10 to 15 single pressure diagrams are used. Two examples are given here:
