Weigh feeder – Rotaweigh

Rotary weigh feeder

Logo de la marque Hasler

The ROTAWEIGH is a rotary weigh feeder. The rotary weigh feeder is supplied from the top of the ROTAWEIGH via a regulated valve, directly from a

silo, a surge tank or a pre-installation. A control valve is an actuator that combines a valve body with electric or even pneumatic actuation in industrial applications. This rotary weigh feeder is embedding a weigh metering unit which is installed directly on the chassis of the machine. The weigh metering system will incorporate weighing sensors (weighing devices) that allow live calculation of the weighfeedrate by the electronic controller and its definition of the right speed response. The rotary feeder is transporting material by rotation on an almost full revolution. ThE articulation, neutral point of the weighing, is in the axis of the rotaweigh input to cancel the influence of the entry of the material in the ROTAWEIGH

Mobile application

The SCM-3 is supplied with a Process Display Unit off ering a 5-inch touch screen and 16.7 million colors.
As an option a mobile application is proposed.


Informations and signals from the feeder sensors are processed in the SCM controller which calculates the flowrate, the totalization and the regulation signal.
Detailed alarm informations are obtained via the display (SDU).
