Cold mechanical regeneration using a grinding wheel unit

4 Cold mechanical regeneration using a grinding wheel unit 

A reduction of the amoimt of sand for disposal and of the consumption of new primary sand. 

A reduction in the consumption of lustrous carbon, in the case of green sand. 

An increase in moirlding sand properties, restrlting in a reduction in the munber of scrap moulds and in the number of rejects in finished castings. 

The regeneration of sand requires additional energy and causes additional dust emissions and residual dust for disposal. However, the use of regenerated sand in the moulding process allows a reduction in the amormts of lustrous carbon used.
