re Longitudinal Sieve of Cement Mill
Please see the new longitudinal sieve analysis for the same
finish mill and give me your comments.
At intermediate diaphragm residue on mesh#8 is 0.9% so chamber
one is over grinding the material. Also since the second chamber inlet material
is too fine therefore we can use max ball size of 30 mm in second chamber. In later
stages based on new longitudinal sieve analysis we can reduce the filling
degree of first chamber and increase the second chamber.
I appreciate your comments and thoughts.
