Failure Analysis of Scraper Conveyor in Vertical Mill Production Line

Guide: The scraper conveyor is an important means of transport for conveying materials in the vertical mill production line. In the daily production, if the management of the scraper conveyor is not taken seriously and the maintenance is not in place, various accidents will be caused. Let's share the causes and prevention of common faults in the scraper conveyor.

The scraper conveyor is an important transport tool for the vertical mill production line to transport materials. In the daily production, if the management of the scraper conveyor is not taken seriously and the maintenance is not in place, various accidents will be caused. Let's share the causes and precautions for common failures of the scraper conveyor.

The floating chain is a common fault of the scraper conveyor. The vertical mill production line often shows that the motor emits a very sharp sound; the scraper scrapes too little coal, and there is no large amount of coal flowing through the unloading head. The cause of this failure is that the fuselage is not flat, not straight, and there is a groove; the scraper chain runs on the coal; the scraper is missing and the bend is too much; the scraper chain is filled with vermiculite or other foreign matter. To prevent this from happening, the precautions are: the scraper chain should be tight and proper; always keep the fuselage flat and straight. The coal should be installed in the middle of the chute; the curved scraper should be replaced in time, and the missing scraper should be filled in time; if the coal is mixed with meteorite or pulled up the mountain, the scraper can be encrypted; the scraper conveyor head and tail Below the middle chute, it is bridge-shaped.

Broken chain is also a common fault of the scraper conveyor. In the vertical mill production line, the scraper conveyor is suddenly running down or accumulating under the nose when the scraper conveyor is running; the scraper is suddenly skewed to one side. The reasons for chain scission are: large chain is too loose or severely worn, or the length of the two chains is different; excessive coal loading, starting the motor under heavy load; the chain link distance of the two chains is different; deformation wear chain There are many rings; the bottom of the working surface is not flat, and there are too many coals in the empty chain. The precautionary measures are: when there is too much coal in the chute or too much coal in the bottom trough, it should be eliminated in time, or the coal at the bottom of the transition trough of the manipulator head should be set up; the tightness of the scraper chain should be adjusted in time, and the deformed scraping should be replaced. Plate, link and connecting ring.

The above briefly analyzes two common fault drift chains and broken chains in the vertical mill production line, analyzes the possible causes of the faults and corresponding preventive measures, and hopes that users pay attention to them.
