Predictive Control of Screen Process Efficiency

The durability of critical wear components, the ability to predict their remaining life and their improved operating efficiency were identified by the Australian coal industry to be a long term strategic objectives. Screen panels used in high capacity multi-sloped screens (Banana screens) are a critical wear component that can affect both availability of the plant and plant performance. The ability to predict the wear and the effect this wear has on downstream processing will also help reduce the number of reactive maintenance events. This report examines the wear and the effect of this wear on two plants and links the wear to efficiency of the downstream unit operations.
