    Zhengzhou haixu abrasives co.,ltd,founded in 1999,has been manufacturing and exporting abrasives for more than 20 years.At first,we mainly produce abrasives such as white fused alumina,brown fused alumina and silicon carbide,but from 2017,in order to meet requirement of some customers,we started to import chromite ore from south africa,wash,dry,sieve,test ,pack and re-export from Lianyungang port,Chine,but recently,we move our production lines to Tianjin port.

    Then what about the specification of chromite sand from our factory-ZHENGZHOU HAIXU ABRASIVES CO.,LTD?
