【正文】 the operation is correspondingly flexible and reliable. To maintain the appropriate temperature in the mill circuit. For example to ensure adequate dehydration of the gypsum when grinding cementthe layout is prepared with provisions for r ecirculation of hot exit gas to the mill inlet. In case the mill feed is wet slag or includes a significant portion of wet additives, addition heat must be provided, for inentance form a heat generator. Otherwise, if the mill feed is very hot, the mill exit temperature controls a damper for cold air intake. Nozzle ring bypass system For slag grinding, a specially designed nozzle ring bypass allow the iron particles to segregate through nozzles without airflow and subsequently be removed by a magic separ ator to minimise — 4— wear of the mill internals. One mill, many products The OK mill efficiently grinds blended cements, with a wide range of additives such as slag puzzolana, limestone and fly ash. Its versatility is demonstrated by the ability to switch bet ween a wide variety of mixes, and to vary the particle size to meet individual needs. Particle size distribution Example of adjustment of particle sizedistribution when grinding to the sameBlaine surface. The required steepness of the particle size distribution curve is attained by sdjustment of the separatorrotor speed, the mill airflow rate and the grinding pressure,
