DEVICE FOR DETECTING THROUGH POINT OF ORE IN FURNACE CHARGING MATERIAL CARRIER

摘要

PURPOSE: A through point detector of an ore is provided to prevent an accident or an interruption for a long time by checking the normal state of a pulse generator and informing the misoperation of an ore detection to an operator. CONSTITUTION: A roller ore detecting unit detects the passage of an ore through the physical position change of a roller by the ore by installing a roller(21) on a belt conveyor. A comparing unit outputs an error signal when an error is generated within a certain range by comparing the ore detected signal of the roller ore detecting unit and a predicted through point. An alarming unit alarms the abnormality of an equipment by operating with the error signal from the comparing unit. Thereby, the productivity is improved.
