As less grinding energy is used in producing a cement of a required fineness in an OK mill and the retention time in the mill is shorter, the product will not be heated up as much as in a ball mill. 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

Sep 11, 2018· Tests carried out at the Lafarge Plant in St. Constant in Canada, utilizing the same mill with two different ball charges, have shown that for an equal mill throughput the finer ball charge had the higher mill retention time. Mill throughput could be easily .
Jan 07, 2015· The capacity of the mill depends on the cross section and hence the diameter of the mill. On the other hand, the fineness of the material at the mill outlet depends mainly on the retention time of the material in the mill. The main influencing factor on the retention time is the mill length.
allows for a shortened cement retention time in the mill which, in the end, leads to significant energy savings for each ton of cement produced. • Maintenance cost reduction Shortened cement retention time in the mill leads to a less intensive use of the grinding system, therefore reducing mill maintenance cost per ton of cement.

Mill retention time is also another parameter that should be taken into consideration. The particles that reach the certain fineness inside the mill are taken out of the mill quickly with the help of air. Grinding aids also affect the retention time by increasing the cement fluidity . These effects of grinding aids and ventilation on mill ...
Plants that burn waste fuels enjoy a negative fuel cost (they are paid by industries needing to dispose of materials that have energy content and can be safely disposed of in the cement kiln thanks to its high temperatures and longer retention times). As a result, the inefficiency of the wet process is an advantage—to the manufacturer.
A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
In the cement industry, a ball mill for this application is called a Preliminator mill. ... Characteristics of the long mill: Longer retention time per particle and the production of a higher percentage of fines in the micron sizes. This is an important consideration in cement clinker grinding.
