quartz sand brazilquartz sand chromite

The mixture of chromite sand and quartz sand which arises inevitably at the shake-out grid usually leads to problems with the quality of the casting, as well as increased costs, when reused. For this reason, these sand varieties must be separated and put back into the mold material cycle separately.

Using chromite sand to improve the wear resistance

2021-3-18  The mechanical properties and wear resistance of the grinding balls produced by the lost foam negative pressure casting process using quartz sand as the molding sand are relatively poor. In order to improve the wear resistance of the grinding balls, sabbia cromata can be used instead of dry quartz sand. Because of chromite sand The heat storage coefficient and thermal conductivity coefficient of the chromite sand are much higher than that of quartz sand
