roller press gap measurement of a cement grinding roller press

  • Finding failureInternational Cement Review

    Roller presses grind raw materials and cement in a cost-efficient way. However the highly dynamic process causes excessive stress on the bearings of the grinding rolls and the two drive trains which ultimately fail and lead to unplanned stoppages. An online condition monitoring system that uses acceleration sensors can help avoid such stoppages.

  • High pressure grinding rolls (HPGR)

    High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain size.

    Resulting in friction between the roller sleeve and the hub after a long time of friction coupled with the large radial force of the grinding roll it will inevitably lead to faster local wear resulting in a gap between the roller sleeve and the hub which can not ensure the contact area which will lead to wear.
