Quality control Question 27
I own a 400tpd cement plant. Because of a recent reshuffle in government, the state is now asking us prove our pollution-free state of running. How can I prove the technology is a pollution-free one.

Quality control Question 28
I wish to know if the test of consistency of cement pastes has any significance as regards the quality of cement, eg a cement of lower consistency (<25 per cent) is better than a cement of higher consistency (> 25 per cent water). Secondly: it is observed that most of international cement standards set limits only to mortar compressive strengths although in practice the main usage of cement is in concrete applications. May I know why is that?

Re: Quality control
To calculate the velocity of the gases at the mill fan inlet you need the static pressure in addition to the dynamic pressure. If the mill fan has a capacity of 133m3/s then you need to divide this by the cross-sectional area of the inlet ducting to arrive at the design gas velocity of the fan
