【正文】 he 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, in bination with the appropriate height of the dam ring. Optimisation of operation Adjustment of mill airflow and grinding pressure for optimisation of the operatinon, including adjustment of the particle size distribution, can be made immediately. Adjustment of the dam ring, however, requires a mill stop, but only for a few hours. Switching between different types of products, for example from portland cement to slag, only requires easily made operating
