clinkering

Another distinct category is the modified cement compositions aimed at reducing the clinkering temperature and/or reducing the content of limestone in the raw mix.

5.1 Raw-mix design 1993

Since the clinkering process requires a raw meal, which is ground to a fineness of about 10 per cent retained on 170 mesh sieves, it is generally preferable to grind the raw mix in a closed-circuit system for efficient control.

6.1 System design 1993

Then, again, as the steam is delivered in among the coke in a jet, or a series of jets, it has the effect of almost entirely preventing any clinkering or slagging of the earthy and silicious materials, which form such a large portion of the substance of the coke obtained from Scotch cannels, sometimes as much as from 15 to 20 per cent.

The combustion of a vastly increased bulk of pulverized coal and a greatly enlarged combustion zone, extending about forty feet longitudinally into the kiln -- thus providing an area within which the material might be maintained in a clinkering temperature for a sufficiently long period to insure its being thoroughly clinkered from periphery to centre.

Edison, His Life and Inventions, vol. 2 1910

The comparatively short length of the sixty-foot kiln not only limited the amount of material that could be fed into it, but the limitation in length of the combustion zone militated against a thorough clinkering of the material, this operation being one in which the elements of time and proper heat are prime considerations.

Edison, His Life and Inventions, vol. 2 1910

In all rotary kilns for burning cement, the true clinkering operation takes place only within a limited portion of their total length, where the heat is greatest; hence the interior of the kiln may be considered as being divided longitudinally into two parts or zones -- namely, the combustion, or clinkering, zone, and the zone of oncoming raw material.

Edison, His Life and Inventions, vol. 2 1910

Consequently, beyond that point there was a zone of only about forty feet, through which the heated gases passed and came in contact with the oncoming material, which was in movement down toward the clinkering zone.
