Scraper chain: Servicing & maintenance:
High-strength underground operation easily causes the agglomeration
between the scraper chains since dust in air may block chain links
to become hard. Therefore, when the scraper chain enters the chain
wheel, its action is not smooth. If the chain links become hard, it
will result in cracks of bolts, casing or base plate, or stagnation
of scraper chain.
Severe agglomeration may result in connection corrosion.
If the scraper chain is left unused for a long time, connection
corrosion will occur. In this case, the chain links will become
hard, and cracks reoccur.
