Chromite Iron Ore Sand foundry
Description:
Chromite Iron Ore Sand is a naturally occurring spinel consisting primarily of the oxides of chrome and iron. It is a by-product of ferro-chrome production and is mainly used in foundry applications and in glass production. Chromite Sand for foundry use 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.
Chromium Cr powder is made from South African chrome ore, which is crushed by a crusher, then ground by a ball mill and grinder with strict control of time and speed, screened, dried, and other steps to obtain the powder of different sizes we need. chromium powder can be used in ceramics, pigments, dyes, coatings and other fields.
