The Application of Rubber and Polyurethane Screens for Sizing, Dewatering and Heavy Medium Recovery

We are all no doubt aware that with today's high costs it is more important than ever to get the maximum possible return on capital invested in the mining industry. Screening is an important and often costly process in the size classification of industrial minerals and for this reason alone it is essential for both managers and operators to fully understand what type of screening equipment is best suited for a particular application and why. The advent of elastic materials such as rubber and polyurethane have added a new dimension to the process of screening. It is important to understand why the physical properties of these materials can be of benefit in the screening process, and recognise which type of screening applications best take advantage of these orooerties.
