WhatsApp As the Bond Work Index increas es, the capacity of the mill to produce a constant product size decreases. A reduction in BWI should also lead to an increase in production, however the amount of the increase may be reduced based on other factors. Vertical ball mills appear to be somewhat less sensitive to changes in feed size and BWI when operated in series with a horizontal ball mill. This is ...
