Rotary weigh feeder

Logo de la marque Hasler

Available models : 1500 – 1800 – 2200

The ROTAWEIGH is a rotary multicells weigfeeder. The feeding should be regulated upstream, via a flow control gate.
The neutral point of the weighing system is in line with the inlet in order to exclude influences of the material above the ROTAWEIGH .
The rotation speed is adjusted to get the measured flow constant and equal to the given set point.
The ROTAWEIGH is delivered with an inverter model AT V32 from SCHNEIDER brand that is specially programmed to ensure safety in the event of temporary blocking of the rotor
