Double rotary weigh feeder

Logo de la marque Hasler

Available models: 1000-1400

Function

The TWIN ROTAWEIGH is a double level rotary weighfeeder. The material is fed by the top of the TWIN ROTAWEIGH, directly from a silo, a surge bin or through a prefeeder. Then it is conveyed by rotation over half a revolution, to an intermediate opening giving the way to a second level, where, after another half revolution, it reaches the outlet. The neutral point of the weighing system is in line with the inlet in order to exclude influences of the material above the TWIN ROTAWEIGH.

The rotation speed is adjusted to get the measured flow constant and equal to the given set point.
