WhatsApp: +86 18838072829Introduction: The ball mill is a tumbling mill that uses steel balls as grinding media. Ball mills can be used in wet or dry systems for bulk and continuous milling, and are most widely used in small or largescale ore beneficiation plant. Dry grinding: suitable for materials that react with water, such as building stones such as cement and marble.
WhatsApp: +86 18838072829Scheibe et al. demonstrated that different addition strategies such as dropping, injecting or vaporizing have no significant impact on the grinding aid performance in tumbling ball mills, mainly because of the good mixing effect within this mill type. Weibel et al. [29] reported that the dispersion of the grinding aid
