Refractory grade 3-5mm chromite sand 3-5mm
Description for chromite sand:
We can produce refractory grade chromite sand of: 0-1mm, 1-3mm, and 3-5mm. The raw material is imported from South African, then through crushing, screening, grinding and other procedures. Its main chemical component is Cr2O3, and the Cr2O3 content of the products we provide is generally greater than or equal to 46%.
