Systems for volumetric and gravimetric dosing

Due to the growing demands on product quality, the requirements for dosing accuracy and the tolerance limits in recipe dosing are constantly increasing. To do justice to these, you need to know your bulk material exactly: grain size, shape and properties. Does the bulk material flow? Is it bridge-forming or fluidizable?

As a dosing screw manufacturer, we have developed a dosing unit based on our experience, which is suitable for all bulk materials thanks to its different designs and possible combinations.

Advantages for your bulk material handling

Modular dosing unit in 2 sizes

For maximum flexibility and efficient product discharge

Emptying aids for difficult bulk materials

Thanks to the possible integration of agitators and activation aids

Versions with and without a weighing system

The weighing system guarantees highest accuracy in batch operation

Closed and therefore dust-free dosing

For a safe and environmentally friendly overall concept for your dosing system

Design and functions of the dosing unit

  • Dosing screws in different designs for optimum dosing results for powders and granules
  • Dosing system design in steel or stainless steel in the capacity range from 5 to 5,000 L/h
  • Version for gas or dust ATEX zone (zone 1/2 or 21/22)
  • Polished surfaces that come into contact with the product: particularly hygienic for food applications
  • Easy to clean thanks to the additional removable front panel
  • Different drive systems to suit every metering application: available with fixed or adjustable speed in the range max. 1:100
  • Various sealing systems: stuffing box, shaft seal, and special sealing systems for food or chemical applications
  • Integration of washing nozzles for the safe removal of product residues
  • Weighing systems tailored to your application for high accuracy in batch operation

Requirement

The conveying and dosing of clay powder.

The solution

  • Pneumatic conveying of the product with pressure conveying into a receiving container.
  • Subsequent conveyance of the product by means of a screw conveyor into a swivelling screw dispenser
  • Subsequent gravimetric batch dosing on two conveyor belts.

Requirement

The emptying, dosing and conveying of EPDM granules.

The solution

  • The product is emptied at different positions via big bag emptying stations.
  • The product is dosed into a rotary feeder via a volumetric dosing and pneumatically conveyed to various receiving points.

Requirement

To produce colour mixtures, different products have to be dosed according to the recipe for the mixing process in a very small space.

The solution

  • The EMDE Bulk Batch System has a central recipe management system for this purpose.
  • Depending on the requirements, the required products are dosed into the mobile containers and transported to the existing mixing system via the container system.

Requirement

For the project, containers had to be emptied dust-free and the powder added to the process.

The solution

  • The core of the project was a emptying station that enabled dust-free docking and undocking of the system with an OEL value of 100 – 1,000 µg/m³.
  • The product is added to the process via a gravimetric dosing unit with a differential dosing scale.
