Simple mechanical regeneration of cold-setting sand

3 Simple mechanical regeneration of cold-setting sand 

A reduction of the amount of sand for disposal and of the consumption of new primary sand. Cross-media effects 

The regeneration of sand requires additional energy and causes additional dust emissions and residual dust for disposal. 

For fliran cold setting monosands regeneration ratios around 78 % are reported. 

The technique can be used for all cold-setting sand, excluding silicate sand. The regenerated sand can be re-used in the same moulding cycle, with small additions of new sand to level-off quality losses.
