We have nine washing plant with huge production capacity nearby mining area. We have rich experience in processing minerals. We have perfect washing system which is capable of removing all the impurities. We have differentiated material by their whiteness and chemical physical property. 80% Levigate China Clay is supplied in the ceramic market.
SR-92 is our premium grade of china clay with maximum natural brightness, fine material with impurities and snow white color. We provide in noodle form.
SR-90 is our second grade of china clay, with 2% lower brightness than first grade. Appearance is in white color.
1RL is our most running grade in china clay. It is slight pinkish in color with high plasticity. It is mainly used in ceramic body. It has good shrinkage and casting rate. The main point is that it has low cost product with high alumina percentage.
