Our weigh belt feeder for fertilizers suits perfectly in the process of the phosphoric acid.

The material crosses the entrance hopper of the measuring glass and is extracted from the storage silo by the band (indirectly), then forwarded to the weighing bridge.
Thanks to the consideration of the length of haul between the weighing bridge and the pier of the measuring glass, the flow is calculated according to the speed of the band and the moderate load when it reaches the pier of the measuring glass.
The flow is maintained constantly by the controller SCM in the pier of the measuring glass by modification of the speed of the band according to the moderate load and to the applied instruction.
