Daswell supplies ball mill combined with classifier and vertical wet grinding mill, which can make ground calcium carbonate both in dry and wet ways. Controlled ground calcium carbonate particle sizes. Both the grinding mills, ball mill with classifier or wet grinding mill, can produce ground calcium carbonate with required fineness.
An evaluation of Relo grinding media (RGM, Reuleaux tetrahedron-shaped bodies) performance versus standard grinding media (balls) was made through a series of grinding tests, including a slight modification of the standard Bond test procedure. Standard Bond tests showed a reduction in the Bond ball mill work index (wi) of the mineral sample …
