Sep 16, 2001 The fault detection system was first evaluated at a copper mine in Arizona in the United States. It was able to detect the loose mesh and bottoming out on an operating screen. As the screen was used for production, limited time was available for field-testing. To support this, a vibrating screen test rig was developed in the SKF laboratory.
