Heavy duty weigh belt feeder for powdery bulk materials
The POWDRIT weigh belt feeder is used for the continuous, gravimetric feeding of powdery bulk materials. Depending on the material to be handled, the infeed to the POWDRIT is controlled by a suitable prefeeder, i.e. rotary star feeder, feeding gate, etc.
The electronic controller works as an independent unit or integrated in a multi component system. It also controls the prefeeder, depending on the application, by an independent PID control loop as a function of the settling chamber filling level or in a classical double regulation loop, based on the beltload. The electronic controller can be linked to a supervisory process control system via an optional interface module.
- Modular feeder design for length and width.
- Inlet settling chamber with triple skirt preventing material leakage between chamber and belt.
- Engineered for high rigidity.
- Patented belt tensioning and auto centring system.
- High quality conveyor belt with integrated index, cleaned inside and outside by scraper elements.
- Lateral belt replacement.
- Standard discharge hood for total dust free operation.
- Material enclosure between inlet settling chamber and discharge hood as option.

Weigh belt feeder with options
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.
- For the de-airing and stabilisation of fluidised bulk materials before being conveyed over the weighbridge.
- Equipped with a set of chain curtains and retention plates; the position of these elements is optimised during start-up as a function of the material flow behaviour.
- To be connected to the plant dedusting installation for the elimination of the air from the fluidised bulk material.
- Can be fitted with a «float» level measuring system to control the prefeeder via a dedicated 3-point control loop so as to maintain a preset settling chamber filling level. With this control concept the material is extracted from the settling chamber with a material bed height given by the shear gate setting
