Barter is the present and the future of international trade, especially for people who is starting in the import export business. Barter and more: Triangular operations.
The central slot is a large part of the scraper conveyer's usage and consumption of coal mining face. The replacement frequency of the central trough in large coal mine can reach two or three times a year. The replacement of the middle slot is mainly due to the wear of the middle slot, scraper parts manufacturer below to take a look at the middle slot wear reason.
There are many reasons for the poor wear resistance of the central slot, the first is the production and manufacturing. In the manufacturing process, the element content of the middle groove side exceeds the set range, impurities in the molten steel exceed the standard, internal defects and so on will cause the wear resistance to decline. In the heat treatment process of the groove side, the process is not good, will also cause the groove side strength is not enough, deformation, etc.
In the process of conveying coal, scraper conveyer not only transports coal, but also transports coal gangue, which has less wear to the middle trough, while coal gangue has more serious wear to the middle trough, which leads to the decrease of wear resistance of the middle trough. In addition to coal transportation, the central slot also needs to bear the extrusion pressure and impact force caused by large coal and rock stuck in the central slot, so the central slot is badly worn.
Damp air, noxious gases, and other factors can also wear out the central slot. It is very necessary to improve the wear resistance of the central slot and other parts of the scraper. If you want to know more information about the parts of the scraper conveyor, you are welcome to continue to pay attention to the manufacturer of the parts of the scraper - Henan Shuangzhi.
