Factory Price Foundry Grade Chromite Sand
China Factory Price Chromite Foundry Sand
High chromite stuffing sand is mainly made up of imported high pure chromite sand with reasonable particle size distribution, and suit for LF, VD,RH and other refining process.
China Factory Price Chromite Foundry Sand 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.
