KLEIN AG
Sand Regeneration
CLUSTREG® for inorganically (water glass) bonded sands and ROTAREG® for cold resin-bonded sands.

With decades of experience in building sand reclamation systems and a practical, solution-oriented approach, KLEIN develops successful solutions for every challenge.
CLUSTREG®: Inorganic water glass binders are virtually emission-free in the casting process. KLEIN has developed the mechanically adsorptive CLUSTREG® process for regenerating inorganically bonded sands. It enables a closed sand cycle in the casting process, conserving the increasingly scarce resource "sand" while operating economically and energy-efficiently.
ROTAREG®: Cold resin-bonded sands can be mechanically regenerated. Sand recovered using conventional single-stage mechanical regeneration can be largely reused; a second regeneration stage significantly increases the proportion of reclaimed sand in the moulding sand and substantially reduces the need for new sand.
