Corné Kleyn, product manager for screens at Weir Minerals Africa, explains how the efficiency of screens can be defined, measured and increased.
Mining and aggregate processing equipment is used for a number of different reasons: from separation and washing to dewatering. However, regardless of the aggregate product’s final application, be it construction material or road surfacing, the property a customer is most interested in is the average particle size.
Separating and sizing a wide range of particle sizes generated by crushing equipment is one of the most important functions after the milling process, and screens play a large part in the operation.
The role played by screens is central to the quarrying process and Kleyn says there has been a trend towards increasingly large units being installed at bigger quarries as operators look to increase their output. However, he says that regardless of how big a screen may be and what volume of material is passing through it, it is vital that it operates efficiently.
