Vibrating sieves are used to remove grit and fine particles from the pellet flow. They are available in a single-deck and a double-deck version. The sieve frame is suspended in a frame made up of hollow sections by means of laminated springs. The sieve inlet has a flexible connection to the screen area. The single-deck version has two outlets (one for pellets, the other for fines).
The double-deck version has three outlets (coarse material, pellets and fines). The cover is secured with quick-release fasteners for simple screen changes. It is driven by a special vibration motor which ensures virtually vibration-free operation.
