Consumption Energy In Grinding Ball Mills

Crushing or grinding is often used during mining to achieve a consistent size of minerals while saving energy consumption both ball mills and tower mills are not recommended to grind fines below 40 μm this is because these mills tend to over grind products that do not meet the optimal grinding range.
