  • Grinding control strategy on the conventional milling

    Grinding Control Strategy On The Conventional Milling

    introduction there are six parallel conventional milling circuits at palabora mining company. each milling circuit consists of a rod mill followed by a ball mill in series. crusher product (-9 mm) is fed to the rod mill, and the water is fed in ratio to the ore feed mass. the rod mill,micronization in the pharmaceutical industry,ball mills micronize material by agitating it in a vessel using steel or ceramic balls or other media. apart from ball milling’s comminution function, the technique also serves as an intensive mixing technique capable of producing co-ground, pharmaceutical-­­excipient mixtures comprising amorphous drug forms mixed with suitable hydrophilic excipients at the molecular level. 3
