WhatsApp: +86 18838072829For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R,,
WhatsApp: +86 18838072829Ball Charge: The ball charge is the total number of grinding stainless steel balls or ceramic balls in the barrel. The ball charge size and composition can vary depending on the material being processed and the desired particle size. Milling Media: Milling media is the material used to grind the powder.
