SEPARATOR EFFICIENCY SUMMARY 

Cement Mill 1 is currently running at the rate of 165tph at 3080 Blaine on OPC.



Upon the complaint of product feed have coarse mixed particles, separator efficiency was planned to conduct using tromp curve.



Three sample were taken from the separator feed, separator reject and separator product fines.



Tromp curve was drawn and following results were extracted.



Circulation load is 160% and is okay.



Bypass 31 which is higher than third generation separator shows the fine product that directly goes to reject need to be control < 10%.



Reduce Imperfection is 0.38 which is close to high efficiency separator.



Separator efficiency by tromp curve was measured again after adjustment of the separator draft and reject flow. Follow results were measured.



Circulation load is 170% and is okay.



By pass 14.3 which is very close to high efficiency separator.



The new flow and separator flow , total feed , speed and reject is considered as target for OPC at that Blaine.
