100 % digital connection<br />
• Modular design<br />
• Construction avoiding material retention, no horizontal<br />
surface, a minimum of dead angles<br />
• High rigidity thanks to folded side rails<br />
• New belt tension device with tensioning roller<br />
• New automatic belt centring system<br />
• 5 standard belt widths and various belt types (selected<br />
according to the material characteristics)<br />
• Speed sensor integrated in geared-motor<br />

Operating Operating principle principle<br />
•<br />
•<br />
The material flows through the inlet onto the<br />
belt and is conveyed to the weigh bridge<br />
The SFT load cell measures the belt load<br />
which is the material quantity on the weigh<br />
bridge<br />
• The speed sensor measures the belt speed<br />

The flowrate<br />
Q (kg/h) = P (kg/m) x V(m/s)<br />
at the feeder discharge point is maintained<br />
constant by the electronic controller at the<br />
