Choosing the right screening area
Getting the right screen size is important. If the screen is too small then you will end up with excessive undersize particles in the overflow. But it’s also possible to have a screen that’s too big. Larger screens mean thinner material beds, and that can cause particles to bounce over the deck without falling through an aperture. The result can be the same – excess undersize in the overflow. Maximizing the efficiency of a screening operation, then, depends on getting the screen as close to the optimal size as you can.
