Abstract

Abstract: The abnormal operation conditions of doubleended ball mill separator for 1000MW ultra supercritical boiler were introduced. The problems, which happened during the separator operation and maintenance, were expounded. Aiming at the influences of internal wear and air leakage, the structure design, maintenance and management and equipment reformation of this type mill separator were analyzed comprehensively; and some improvement suggestions were put forward.
