- Circulating Load Volume In Ball Mills

Apr 29, 2018 As the circulating load increases to higher levels, it is also not uncommon for the pump or the cyclone to become the capacity bottleneck due to volume constraints. These volume constraints are not always readily apparent, leading to the assumption that the increased circulating load has limited the ball mill capacity.

MoreSep 10, 2017 Cytec Handbook. Why have a large circulation load:. If a product all finer than a certain critical size is required, the capacity of the ball mill is increased considerably by using it in closed circuit with a classifier and this increase is made still greater by increasing the circulating load in between the ball mill and the classifier (Fig. 70).

MoreWhat is the most reliable method to determine actual circulating load in grinding circuit? A simple one - ball mill w/ hydrocyclone. I observed that the most common methods applied are (1) use of water balance - taking samples of cyclone feed, cyclone underflow and cyclone overflow.
