An industrial test on a low fineness cement is introduced as a starting point to sum up some general technical issues (mode of action of grinding aids, mill retention time, mill ventilation, etc ...

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.

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

Cement grinding with Horomill. The finished product is collected in a dust filter. The Horomill is a compact mill that can produce a finished product in one step and hence has relatively low capital costs. Grinding Portland cement with a Blaine of 3200 cm 2 /g consumes approximately 23 kWh/t and even for pozzolanic cement with a Blaine of 4000,

Download Citation on ResearchGate | Optimization of continuous ball mills used for finish-grinding of cement by varying the L/D ratio, ball charge filling ratio, ball size and residence time ...

However, mill operation at high circulating loads often results in a void filling somewhat above this amount. Since additives reduce agglomeration, and consequent dry powder cohesion, flowability is improved and thus the mill filling level and retention time are lower when additives are present.

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 ...

The number of stresses can be characterised by the average retention time of the ground material inside the mill if the ball charge grading remains unchanged. The optimal retention time depends 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.

And the retention time of the material in the mill is prolonged to ensure the fineness of the cement. When a large block of material is present, the cement grinding table can be reduced suddenly by 10-20%. (4) the moisture of the grinding material increases.

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.

The OK 54-6 cement mill's time as the "world's largest OK mill" will be fleeting as an even larger mill, an OK 62-6 cement mill, has been sold to Shah Cement. The installation of the first OK mill for raw grinding is the next step in the evolution of the FL OK™ mill.

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.
