CHROMITE SAND AFS40-45 AFS40/45
Chromite 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.
Zhengzhou haixu abrasives co.,ltd,founded in 1999,has been manufacturing and exporting abrasives such as fused alumina and silicon carbide for more than 20 years.
To meet with our customers who work in foundry field,we started to import chrome ore from south africa and set up our production line to wash,dry,sieve,test our chromite sand in Lianyungang port China,most of our chromite sand are reexported and the most sizes are:
AFS 25-35 AFS25-30 AFS30-35 AFS35-40 AFS40-45 AFS40-50 AFS45-55 AFS45-50 AFS50-55 AFS55-60 AFS60-65 0-1mm 200mesh 300mesh 400mesh
Today just list the tachnical datasheet of chromite sand AFS40-45 for your reference:
