Weigh belt feeder for granular materials
The material flows from the storage silo through the inlet onto the belt and is conveyed to the weigh bridge.
Taking into account the distance between the weigh bridge and the discharge point, the flowrate is calculated according to the load at the discharge point and the belt speed.
The flow rate is kept constant by the SCM-3 controller modifying the belt speed according to the load and the setpoint applied.
- Construction materials
- Gypsum – Plaster
- Modular construction
- Adapted and smooth surfaces
- High rigidity thanks to folded side girders
- Automatic belt tension device by spring-loaded tensioning roller
- Auto-centring belt system
- Turn-down ratio : 1:10 ; 1:20 ; 1:100
Spillage conveyor :
One ore more scraper(s) driven by two chains recover the particles that escaped from the weighfeeder and convey it to the common discharge point.
Hammer Gate :
This gate limits the height of the extraction section while enabling the passage of oversized material lumps, the mobile elements (hammers) lifting then returning to their original position once the material lumps have gone through.
Scraper - sticky materials:
Integrated into the new GRAVIT or under renovation, this scraper keeps the belt clean when transporting sticky materials. Maintenance is facilitated by its hoodopening mechanism from the outside.
The taring is thus maintained, preserving the dosing accuracy
Other options :
- Inlets : Vibrating / elongated / rock-box
- Rod closing gates / cut-off gates
- Vanne à tringles
- Material cover
- High temperature resistant belt
- Digital load cell
Weighfeeder signals and information, such as Weight, Speed, Belt tracking, Belt index are directly connected to the SCM-3 controller. The SCM controller calculates the actual flowrate, totalizes the conveyed material and generates the control signal for the variable speed drive.
Detailed alarm informations are obtained via the display (SDU).
* SCM-3 Field or Panel version: see : SCM-3-F-260.001-E. or SCM-3-P.260.001-E
The SCM-3 is supplied with a Process Display Unit offering a 5-inch touch screen and 16.7 million colors.
As an option a mobile application is proposed.
