Keep your sand close – with Modular Sand Reclaimer

There is a rising pressure to find a way how to treat waste foundry sands, as environmental legislation gets tighter and waste sands have become more and more difficult to landfill. Imagine being able to reuse this sand by regenerating it to required specifications – in your own production facilities.

This means you can start saving right away – and greatly reduce the carbon footprint of your operation.

 

Better than
virgin sand?

Silica sand undergoes a phase transformation to the high temperature phase during the thermal recycling process. Even though the phase transformation itself is reversible, the discontinuous volume change that occurs at the transition temperature causes irreversible changes of the sand grains’ surface: loosely bound structures on the surface are removed, the specific surface area decreases, resulting in reduced binder consumption, and the thermal stability of recycled sand in the casting process is higher than that of virgin facing sand, which undergoes the phase transformation for the first time when it comes into contact with liquid iron.

Other solutions

In certain locations we are offering a complete sand renewal service, taking your used sand and returning it processed to your specifications.
