The maintenance and cleaning services are made easier by the front opening covers, which also allow a quick change of the mesh.

An eccentric adjustable weight system installed on a vertical shaft on the screen center guarantees its exact oscillation which, combined with different revolution, frequency and amplitude, may adapt to any kind of chips. The screen meshes can be easily replaced in case of changing the selected chip sizes or for maintenance purposes

SAFETY

Suspended by steel cables (plus auxiliary safety cables), the screening is performed in an efficient, silent and precise way. The sturdy sustentation beams, supported by concrete columns, do not allow vibrations to be transfered from the screen to nearby facilities.
