When inspecting a screening process, the suggested improvements are always dependent on the customer specific processing conditions and exact application. Sometimes the solution is more complex than at other times. In the image below, taken at a customer site, the problem and solution were obvious to us. As the screening media apertures were located just above the cross beams, stones were easily getting stuck. The pegged stones resulted in unnecessary wear on the screen. By removing the troublesome apertures, a blank surface was created, thereby protecting the screen.
There is no universal solution to solve all screening media related challenges. A good start is to look at pegging, blinding and maintenance – three areas which greatly impact the screening process.
