Cement mill Residue - Page 1 of 1

Re: Cement mill Residue. Dear Mr Jatin, You have not mentioned circuit of your mill.I assume that it might be a closed circuit cement mill. Best possible way to reduce residue on 45micron is by increasing circulation factor across the mill.The other way is to decrese cut size of your dynamic separator by increasing cage rotor speed.

Cement Grinding Optimization - LinkedIn SlideShare

Due to limitation of the mill’s rotational speed, the smallest ball size is usually restricted to about 15 mm. Cement grinding using stirred mills (Pilevneli and Azizli, 1999) indicates that using smaller media (5-8 mm range) improves grinding energy efficiency up to 50% using stirred mills. For specialized types of cement, which are finer than Portland, this figure would be even higher ...
