These screens are designed to separate the product as a whole in two or three fractions. In quarries they are used to eliminate waste product and send large size pieces to the crusher.They comprise an extra robust tray with ribbed sides, operated by motor vibrators or a counter-weighted vibrating mechanism. They have combs or wear resistant steel bars, which are removable for easy replacement. These combs can be arranged in a stepped fashion, which helps to shake off the clay from the stone boluses.The pre-screens may be mounted on springs or rubber shock-absorbers, which are designed to reduce the effects of the impacts that are normal with this application.
