Motion tracking for vibratory equipment

Abstract [en]

The CSIRO Minerals DPP (Dry Particle Processing) Technology has been developed over the last five years. The equipment demonstrate a prescribed vibratory motion which separate material according to size, density and shape. The aim is to develop a motion tracking system, which accurately monitor and record the motion pattern of all DPP units into a computer to enable an expanded view of the movement to be viewed with the naked eye. The system consists of three parts, hardware, software and sensors. The sensors are proximity probes, which produce an electrical output proportional to the strength of an eddy current between the end of the probe and the measurement surface. This signal is then calibrated into displacement. Motion patterns recorded not only show the basic shape of the motion but also varying motion patterns over the length of the device. Results indicated that frequency changes the motion on the DPS unit, but not on the coarse density separation unit and the fine density separation unit. Increasing the weights on the flywheel increases the amplitude of the motion patterns on all units. To further develop the motion tracking equipment errors within the system must be investigated. Another important issue is the degree to which vibration from the DPP devices effect the system.
