Eccentric vibratory screening machine

Applications & designs

Pre-separators are preferably used before the first crushing stage in quarries, ore mines and slag processing plants. The step-shaped screening surface ensures good re-sifting of the material to be screened.

For feed material with stalky and spiky pieces that tend to jam, we recommend a step grate with gaps that widen in the transport direction for optimum results. Two-deck solutions are also possible and complement the grading process.

We build our eccentric vibratory screening machines for you with nominal screen widths of up to 2100 mm and screen lengths of up to 4000 mm.

For efficient pre-screening with perforated plates or step gratings.

Operating behavior & mechanical features

In contrast to free-swinging circular vibrating screens, eccentric vibrating screens are rigidly mounted. This has the positive consequence that the circular motion diameter is permanently maintained and is not reduced by too much feed material. Feed fluctuations or strong impulses caused by individual pieces of rock are easily accepted by our eccentric vibrating screens – they don’t care. The displacement by rubber buffers on a frame, which in turn is insulated from the steel structure, ensures reduced vibration transmission to the steel structure.

By using components that are also used in other screening machines, our eccentric vibratory screening machines guarantee long-lasting and reliable pre-separation.
