OK vertical roller mill - hari_1020 - 10-06-2017 OK vertical roller mill [attachment=16364] Operating advantages The rollers are in a lifted position when the mill is started, ensuring trouble-free start-up. This eliminates the need for an auxiliary drive. A control system monitors the machinery and facilitates operation. Mill design for versatile applications, simple operation and long life Mill arrangement This schematic illustrates a typical grinding installation. The arrangement is very simple and 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 cement the layout is prepared with provisions for recirculation of hot exit gas to the mill inlet. In case the mill feed is wet slag or includes a significant portion of wet additives, additional heat must be provided, for instance from 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 allows the iron particles to segregate through nozzles without airflow and subsequently be removed by a magnetic separator to minimise 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 between a wide variety of mixes, and to vary the particle size to meet individual needs. |
