Chromite sand is suitable for steel casting including foundry such as： Green Sand molding； Shell molding； Pep-Set system； Furan Resin and Alkaline-phenolic Resin； Core moulding Lost foam casting   How to Choose grit size？ Generally，the smaller casting need to make, the finer grit size foundry adopted.The following frame shows it for reference: Less than 500KGS

Chromite sand is used as a highly fireproof sharpener for moulds and cores. Originally from South Africa . The sand is produced by crushing chrome ore and its washing in spiral concentrators, subsequent drying, dust cleaning, screening and sorting as per grain size.

Chromite sand, also known as chrome ore sand or cr-sand, is a special sand for foundry. It is a natural spinel mainly made of chromite. It is crushed, ground, and sieved into a specified particle size, suitable for modeling (core making) sand
