### Cement mills Question 5 - Page 3 of 3

Re: Cement mills. There is no easy way to adjust the particle size distribution of an open circuit mill while maintaining the same Blaine. To do that you need a separator in closed circuit with the mill to send the oversize material for regrinding. You may have some success with grinding aids.

2.2. Approach. To evaluate the effect of the classifications of particle-size distribution of cement, the mix proportion was newly required. Nine mix proportions by the amount of different sizes of cement were classified based on the accumulated remains denoted as R at 10 m (R10), 20 m (R20), 40 m (R40), and 80 m (R80) using an Alpine air jet sieve shaker, as shown in Table 5, and the fineness ...
