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.
THE ADVANTAGE OF CHROMITE SAND Comparing with silica sand，chromite sand can avoid most sand stick on the casting，therefor it can also save cost to make surface treatment. Moreover，chromite can be recycle used for several times upon to different technology. Over all the chromite ore in the world， the one from South Africa are of the
Chromite powder is a naturally occuring spinel consisting primarily of the oxides of chrome and iron after crushing, grinding and sieving. We import crushing Chrome ore from South Africa, wash, dry, dust cleaning, grinding, sieve and pack in China port, then export to all over the world directly, and its main chemical composition is Cr2O3. Chromite
Foundry Grade chromite sand, also known as chromite ore, is a special sand for foundry. It is a natural spinel dominate by chromite. After crushing, grinding sieving and batching to typical Particle size distributions as per customers’ requirement, it is suitable for moulding in foundry. Our standard material is a 4-sieve distribution. This means that 4 sieves contain more than 10% retained. Our current material has more than 90% on the ASTM 40-100 sieves.
