The gravimetric feeding method involves either weighing a requested quantity as a batch or feeding a constant mass flow over time. The choice depends on the process that can be made continuously or in batch mode.
Gericke Loss-in-Weight Feeders generate a controlled, absolutely constant mass flow, as required in mixing processes or extruder infeed.
Robust, reliable and durable construction was the main focus during the development of the series for the Gericke Loss-in- Weight- Feeders with tare compensation DIW-KE, 50, 200 and DIW-E.
As low-cost, compact alternative without tare compensation, the loss-in-weight feeder with 3 robust load cells type DIW3E can be used. The weighing hopper and the feeder are mounted in a frame by individual hopper sizes are realisable.
New in the product line is the twin-screw-feeder type DIW-PE-GZD. A hygiene unit which can be completely disassembled for maximum process requirements.
For the refill of the weigh feeders, Gericke offers perfectly coordinated systems such as pneumatic conveyors or volumetric feeders.
Platform weigh feeders.
The feeders are mounted on stable platforms with high-performance weighing technology.
Applications: Small to medium feed rates
Loss-in-Weight-Feeders with three load cells.
The hopper and feeder are mounted in a frame. Weight calculation is carried out by three robust load cells.
Application: Multi-component feeding systems in the food industry and chemical applications.
The weight of the hopper and feeder is compensated by a spring or a counterbalance which ensures that only the bulk material in the hopper is weighed. This means that the complete resolution of the load cell is available.

Platform weigh feeders.
Loss-in-weight feeder with three load cells.
Gericke loss-in-weight feeders and weigh belt feeders cover a throughput range from approx. 0,2 l/h up to 65.000 l/h depending on the bulk material characteristics. The complete and approved setup of the gravimetric systems reduce installation and commissioning cost.
In general, a gravimetric system consists of: frame with load cells and feeding device, frequency inverters, hopper with lid and inlet and venting spigots and flexible connection sleeves.
