Haas Alva

Mobile electric starscreen Alva

The ALVA starscreen reliably separates two fractions. The  highlight is the integrated screw conveyor for collecting and discharging the fine fraction. The material is transported to the discharge conveyor by the screw conveyor.

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[1]resistant, screw conveyor guarante maximum efficiency
