Second to none Feeding Accuracy with the DIW and DBW Gravimetric Feeding Systems

Precision, continuous and by batch Gravimetric feeding The feeding flow or the batch is captured and controlled by weight. The gravimetric feeding method involves either weighing a requested quantity as a batch or feeding a constant mass flow over time. The feeding process selected depends on the process configuration. Gericke feeding solutions provide flexibility with regard to adjustment to the required specifications. Batch feeding The DIW and DBW loss-in-weight feeders are designed to meet the following requirements: • Highly precise feeding concentrating on feeding accuracy and consistent...

Screw and helix weigh feeder Vibro feeder Platform weigh feeder...

The right system for Kompetente Beratung und bewährte Technik every process Platform weigh feeders Function: The feeders are mounted on stable platforms fitted with high-performance weighing technology. Application: Small to medium feed rates. Advantages: Compact devices, easily installed, protected electronics. Specifications: Feed rate 0.2 – 400 l/h (depending on bulk density) Type: DIW-KE-GLD – as economical single-screw feeder with agitator, optionally available as special model for very small quantities with wind deflector. Type: DIW-PE-GZD – twin-screw feeder – a hygiene unit which can...

Hybrid feeders with tare-compensated weighing system Function: 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 (see diagram on following page). Application: The hybrid feeder, which can be fitted with a screw feeder or vibrating trough, is available for a wide range of applications that demand maximum accuracy and robustness. The hybrid feeder is particularly suitable for very light bulk materials, such as Aerosil (d0.2 kg/l)....

Feeding precision Kompetente Beratung und bewährte Technik The accuracy of the loss-in-weight feeder depends on the bulk material and external influences in the area surrounding the weigh feeder. Various influences can occur: • Overload: Prevented by mechanical stop thanks to hybrid mechanics • Oscillations, contact, shock: prevented by mechanical damping and electronic Pressure Mixer, N2 blanketing Building oscillations Trendtec algorithm, agitator • Flow problems in the hopper, fluctuations in bulk Nitrogen blanket Vibration density possible: Mechanical overload protection Open doors ventilation...

Effective control of gravimetric feeders with Easydos Pro Easydos is an innovative feeding and weighing system that can be used with batch applications, continuous gravimetric feeders (loss-in-weight) and in connection with the controlling weigh belt feeders. User-friendly: The explicit menu navigation makes operation simple, the self-optimising controls simplify commissioning and ensure maximum metering accuracy. Easydos Pro follows on from the older Easydos version and now comes with an integrated Ethernet/IP and/or Profibus DP interface. The new controller has many other advantages: • The...
