Chromite sand is used as a highly fireproof sharpener for moulds and cores. Originally from South Africa (SAMANCOR). 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.

High dimensional stability
Chromite sand , Is a special kind of sand for casting , It is a natural spinel mainly composed of chromite ,It is crushed , ground and screened into specified grain size , which is suitable for molding (core-making ) sand
Application
Chromite Sand in the foundry industry
Its properties enable the material to be used in high duty grey iron and steel foundries as core and mould making sand. Its high thermal conductivity gives it good chilling properties, low thermal expansion gives rise to good dimensional stability. Its basicity being close to neutral allows the use of a wide range of resin bonding systems and inorganic binders, it has a high refractoriness and a broad sieve distribution.
In steel production, Chromite Sand is used as well filler for protection of the sliding gate in large steel holding ladles.
When ground to a fine flour, Chromite Sand is used for the production of green glass beverage containers.
