SLOOTWEGVolumetric and weighing feeders

Volumetric and weighing feeders are mostly used to incorporate additives into organic mixes.

The volumetric feeder consists of a conveyor on top of which a small covered bin is mounted. The front wall is equipped with an adjustable gate to meter the material coming out of the feeder. It is generally controlled by a variable-frequency drive (VFD) which allows the operator to adjust the flow without having to adjust the front gate manually.

The weighing screw feeder meters material with a stainless steel auger feeder. The weight is measured by a load cell, which is monitored by the system’s Programmable Logic Controller (PLC). On top of the feeder is the surge hopper where the additive is placed. A pneumatic butterfly valve opens and closes to refill the feeder.
