Grindability of mixtures of cement clinker and trass

Hosten, C. / Avsar, C.

The Bond method of grindability was applied to clinker and trass and to their mixtures. Kinetic experiments also were carried out in the Bond ball mill with each component and the mixtures to obtain a better understanding of the interactions taking place in mixture grinding. The Bond work indices of mixtures were not simply weighted averages of the component work indices, and they were higher than the work index of the harder component clinker. The breakage rate and breakage distribution parameters of the dominant and harder phase clinker were both time and mixture-composition independent for short grinding times, whereas those parameters of the minor and softer phase trass were time independent but mixture-composition dependent.
