Apr , a lower circulating load will provide the space for increasing the fresh feed rate so, if the circulating load is lower than the low limit, then increase the fresh feed rate mill solid concentration is the most important intermediate parameter to indicate the state of milling
Variables in ball mill operation paul o abbe the first problem will ball mills is that we cannot see what is occurring in the mill the other problem is that many of the independent variables are nonlinear or have paradoxical effects on the end results in ball milling of dry solids the main independent variables are mill diameter mill speed media size solids loading and residence time
Flow, which is the fresh feed to the second ball mill if circulating load in the second ball mill is kept constant, any variation in the fresh feed will ultimately be reflected in the product particle size of cyclone water addition to cyclone feed sump therefore not only controls the cyclone
Product from the mill exits the tank through a stand pipe and then to the cyclone sump the slightly coarser portion of the mill overflow is recycled back into the bottom of the vertimill the recycle system can reduce cyclone circulating load by allowing the mill to preferentially grind the coarser material
