Weigh belt feeder for granular materials

Logo de la marque Hasler

Function :
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 2 controller modifying the belt speed according to the load and the setpoint applied.

  • Easy maintenance and commissioning
  • Flowrange 420 to 600 m3/h

Advantages

  • Modular construction
  • Adapted and smooth surfaces
  • High rigidity : welded girders
  • Auto-centring belt system

Options

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.

Other options :

  • Inlets : Vibrating / elongated / rock-box
  • Discharge paddle wheel
  • Rod closing gate / cut-off gate
  • Material cover.
  • High temperature resistant belt.
  • Digital load cell.

Controller

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

Flow controllers for SCM-3 conveyor belts

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.
