The middle trough of a scraper conveyor is one of the core load-bearing components. It carries coal and materials during transportation, and its wear resistance directly affects the service life and efficiency of the equipment. Common measures to ensure wear resistance include:
Material Selection
The base plate and middle plate of the trough are usually made of
high-strength wear-resistant steel (such as NM400, NM450), which provides
excellent impact and abrasion resistance, significantly extending the service
life.
Overlay Welding Technology
Overlay welding is applied to the base plate and areas exposed to heavy
impact from materials. The hardness can reach above HRC55, which effectively
improves wear resistance.
Structural Optimization
The trough adopts a cast-welded structure for the sidewalls and base
plate, which increases overall strength, reduces deformation under stress, and
enhances impact resistance.
Proper Operation
During use, overloading and prolonged impact of large gangue blocks
should be avoided. Routine inspections and maintenance are essential for
long-term stability.
Regular Replacement and Maintenance
Wear-prone parts should be checked regularly. Depending on the wear
condition, timely replacement or overlay repair should be carried out to ensure
continuous and stable operation.
the wear resistance of the scraper conveyor middle trough depends not only on the materials and manufacturing process at the factory but also on proper use and maintenance during operation. By combining design, production, and usage practices, the service life of the equipment can be maximized.
