Mobile starscreen with oversize recirculation

Exploit the full potential of your production with the HAAS ALVA screening machine. Screen a precisely defined, valuable fraction and seamlessly feed the useful oversize back into the shredder.

The stationary version of the ALVA screen is already impressive in countless applications – now the technology is going mobile!

The oversize material is discharged from the screen deck via a funnel-shaped chute onto the return conveyor. This can be pivoted by 200 degrees. With a discharge height of up to 5 metres, the oversize material can be automatically fed back into the shredder or optionally discharged as a second finished fraction.

ALVA is compact and impresses with an outstanding screening capacity (200 m3/h). The assembly on a hook-lift frame provides flexibility. The electric drive and the wear-
resistant, crew conveyor guarantee maximum efficiency.
