cement mill retention time

In thecementindustry, a ballmillfor this application is called a Preliminatormill. ... Characteristics of the longmill: Longerretentiontimeper particle and the production of a higher percentage of fines in the micron sizes. This is an important consideration incementclinker grinding.

The number of stresses can be characterised by the averageretentiontimeof the ground material inside themillif the ball charge grading remains unchanged. The optimalretentiontimedepends not only on the feed material and the desired comminution result but also on the ball charge filling ratio and particularly on the L/D ratio.

As less grinding energy is used in producing acementof a required fineness in an OKmilland theretentiontimein themillis shorter, the product will not be heated up as much as in a ballmill. This means that a lower degree of dehydration of the gypsum must be anticipated. This may not be a problem if the gypsum is sufficiently

The capacity of themilldepends on the cross section and hence the diameter of themill. On the other hand, the fineness of the material at themilloutlet depends mainly on theretentiontimeof the material in themill. The main influencing factor on theretentiontimeis themilllength.

Acementmill(or finishmillin North American usage) is the equipment used to grind the hard, nodular clinker from thecementkiln into the fine grey powder that iscement.Mostcementis currently ground in ballmillsand also vertical rollermillswhich are more effective than ballmills.

In contrast to ballmills, VRMs have a very high internal circulation, a shortmillretentiontimeand a huge number of classifying steps that carry the well-dispersed fines out of themillsystem. The conclusion? Grinding aids for VRMs increase the powder flowability of the finishedcementwithout reduction of the stability of the material bed.

When the transittimeis high, it will have effect on workability of concrete. This happens due to hydration reaction taking place whencementmixes with water, evaporation of mixed water in concrete and due to absorption of water by aggregates.
