In this study we conducted grinding tests on silica glass using a ball mill, and measured the grind ing rate constant of the feed size decrease. We investigated tlte effects of ball diameter and feed size on the rate constant when the ball mass, feed mass, and the mill's rotational speed were constant.

Introduction: 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 large-scale ore beneficiation plant. Dry grinding: suitable for materials that react with water, such as building stones such as cement and marble.
