We import crushing Chrome ore from South Africa,wash,dry ,dust cleaning,sieve and pack in China port,then export to all over the world directly.
South Africa chromite sand casting South Africa chromite sand casting , Originally from South Africa ,is a special kind of sand for casting , chromite sand casting is a natural spinel mainly composed of chromite , Chromite sand casting used as a highly fireproof sharpener for moulds and cores. Purpose 1 foundry industry Its properties enable the material to be used in high duty grey iron and steel foundries as core and mould making sand. 2 steel industry In steel production, Chromite Sand Casting is used as well filler for protection of the sliding gate in large steel holding ladles. 3 glass industry When ground to a fine flour, Chromite Sand casting is used for the production of green glass beverage containers

Step1: chrome ore raw material is processed by water washing. Step2, drying raw materials to remove water; Step3, drying raw materials into the vibrating screen, screening out the size of the customer needs; Step4, the size of the sieve for magnetic separation, the purpose of iron and silicon removal. After magnetic separation, the chromium content reached more than 46% and the silicon content was less than 1%. Step5: package the finished product.
