Conclusion the circulating load and classification efficiency can have a significant effect on the performance of both closed ball mill and hpgr circuits this is a wellknown fact for ball mill circuits that has been recognised for almost 100 years for hpgr circuits the knowledge is more recent and is still being investigated
Sep 07 2011 re vrm and ball mill circulating load mainly in usa the term circulating load is more often used than the circulation factorcirculating load is percentage of coarse return in relation to fines it can be calculated by coarse return tph x 100 mill output tph normal range of cirulating load in a conventional close circuit ball mill is around 100200
Apr 01 2013 the effect of circulating load and classification efficiency was investigated by morrell 2008 who carried out bond ball mill tests by varying the circulating load and classification efficiency conventional tests with 100 classifier efficiency showed that the relative bond work index was reduced by 8 and hence the grinding efficiency was increased by 8 when the circulating load was

Ball mill circulating loadcirculating load calculation in ball mill circulating load calculation formulahere is a formula that allows you to calculate the circulating load ratio around a ball mill and hydrocylone as part of a grinding circuit for example your ball mill is in closed circuit with a set of cyclones
The high circulating load means the slurry passes through the mill quickly preventing the buildup of fines and is rapidly sent to the cyclones for removal of the fines from the circuit the result is a ball mill more filled with coarse 150 mesh size solids and containing fewer fine 150 mesh size solids both absorbing the power of the mill
