ABSTRACT:
The present invention relates to detection and measurement of wear in machines having relatively rotating housings and parts such as radially extending blades subject to wear which may exceed a critical degree, and in particular to the measurement and predetermination of wear and of conveyance capacity of a scroll type conveyor. The invention includes the use of a measuring device for measuring the distance between the radially outer edge of a portion of the conveyor blade and a reference point in the housing radially and longitudinally fixed with respect to the axis of the conveyor. This measurement is preferably taken at a predetermined first portion of the blade such that the measurement at said first portion is indicative of the wear and/or conveyance capacity of one or more other portions of the blade.
