Ball Mill | Mining Grinding Mill
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.

Wet Ball Mill
The wet ball mill has two types as follow: grid type and overflow type.The grain size limit of the grinding mill is usually 0.2 ~ 0.3mm, so it is commonly used in the first segment. The particle size of the grinding mill is generally less than 0.2mm, so it is suitable for the second grinding of the middle product in the two-stage grinding process.
