New factories of chromite sand founded in Tianjin port
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.but on chromite sand,we started it from 2017,and founded factories in Lianyungang port.
But recently more and more ship from South Africa don’t stop from Lianyungang port again,we have to bulid new factories in Tianjin port to meet requirement of our customers.
Now we founded 3 factories of chromite sand in Tianjin port and all almost have been under normal operation.
Production capacity per day:500tons
