Volumetric feeder MDG-B

Dosing of good flowing to slow-flowing bulk goods

The dosing device MDG-B volumetrically doses flowing to slow-flowing bulk goods with product-specific dosing accuracy. They can be integrated into existing in-line processes or used as a stand-alone devices. 

The volumetric feeder MDG-B designed by MANCON is now manufactured and distributed by PAUL GROTH Mühlenbau.

Starting with our standard design we adapt the dosing device to the product properties, the installation option and the process requirements.
Dosing devices are also available for ATEX zone 22.

Function

The bulk goods reach the tray through the product inlet where they are incorporated by a frequency-controlled dosing element and are transported to the dosing pipe outlet. A separately powered aerator prevents bridging and ensures steady filling of the dosing conveyor.

Areas of use

The feeders can be used in many areas of industrial production given its product-specific designs, for example for 

  • foodstuff (powder, granules, flakes, dried fruit)
  • feedstuff
  • chemical industry
  • construction chemical industry
  • synthetic materials

Standard design

  • Trough, dosing element with drive siutable for frequency inverter and with aerator 
  • Material: stainless steel
  • Glass bead blasted surface
  • Shaft sealing with HD shaft sealing rings
