01Overview
High purity, consistent quality — crushed and graded to specification.
Natural gypsum (calcium sulphate dihydrate) is one of the most widely used industrial minerals in the world. We supply high-purity gypsum rock with consistent whiteness and low impurities, crushed and graded to the size your plant needs.
Cement producers add gypsum during clinker grinding to control setting time, while plaster and board manufacturers rely on its purity for strength and finish. Every lot is sourced from trusted deposits and shipped in bulk, ready for your process.
