The Reibregenerator a plant for the mechanical regeneration of foundry sands.


In this mechanical cleaning process the inorganic binder is removed largely of the grain of sand.


Reuse of sand assumes that this is freed of moisture and binder residues so far, resp. the binder residues are present in a way, that a further moulding process is not adversely affected.


This is ensured by the Reibregenerator.



Advantages of the Reibregenerator:

  • purely mechanical sand reclamation
  • approval free
  • fast amortization
  • low operating costs
  • improved sand quality



A socket suffices for simple installation of the system.

Small systems (as shown) are supplied ready for use and only need to be anchored in the floor.

Larger systems are, depending on the local conditions, installed by prior arrangement.

The system size depends on the performance requirements of the foundry.

  • The sand supply into the Reibregenerator can be done both manually and automatically.
  • Reclaimed sand can be conveyed into a silo or into a wheelbarrow.
  • The parameters are set on the operating conditions (degree of pollution of the sand and binder system).
  • The duration of the cleaning is variably adjustable.
  • Extremely low maintenance - only about 2-3 % of the investment costs per year.
  • Maintenance-friendly design of the entire system.

A research facility is located at the University of Duisburg-Essen.

There is a regeneration of own sand on a trial basis possible.


Ongoing systems can be visited by appointment.

The Reibregenerator was developed in cooperation of Domnick Verfahrens- und Anlagentechnik and Technofond Gießereihilfsmittel GmbH from 2008 to 2012.
