Coal bunker liner has a very low friction coefficient (0.05-0.11) it is self-lubricating outstanding, dynamic friction factor under water lubrication quality coal bunker liner 1/2 PA66 and POM, and second only in the absence of lubrication conditions in the best self-lubricating polytetrafluoroethylene (PTFE) when it is rotated in sliding or working situation, than steel and brass lubricant lubrication even better, so the field is known as the friction cost performance is very desirable friction materials. Coal-pulverizing coal bunker is an important part of the system, in large and medium-sized power plant unit, the main plant coal bunker most used steel and steel. As the material flow in the warehouse, the warehouse wall friction and steel siding damage easy to make coal bunker liner picture, but could easily lead to a rough steel surface coal block. Substantial loss of condition appears to run, one leading to the loss of the base steel sheet protection and accelerated wear to destroy the other hand, sheet lined bunker debris clogging the discharge port, causing coal supply blocked, this time will have to downtime not only affect the normal production of coal bin liner, and caused huge economic losses. Thus, good design and construction of coal bunker liner, to ensure the safe operation of the unit is of great importance. .
