Abstract:This paper introduces the problems existing in the ball mill monitoring system and lubrication system, which are the key equipment of the zinc roasting system in the smelting enterprise. By optimizing the monitoring system and lubrication system of the ball mill, the problems of repeated automatic shutdown and easy wear of the bearing bush, which have existed for a long time in the ball mill, are solved, and the monitoring in the DCS system is realized to improve the stability of the equipment and ensure the safety and stability of the equipment function.
