The material revolution
The application of polymer materials (such as polyurethane) and ceramic coatings increases the wear resistance of idlers by 5-7 times. After a mining enterprise adopts ceramic-coated idlers, the service life is extended from 8 months to 3 years.
Structural optimization
The spinning process replaces traditional welding, increasing the housing connection strength by 40% while reducing energy consumption by 30%. The belt deviation rate is significantly reduced, effectively reducing edge wear.
Precise installation
The parallelism error is controlled within 0.5mm/m, which can reduce abnormal wear by 60%. It is recommended to use a laser calibrator for installation to ensure that the axis of the idler group coincides with the centerline of the conveyor belt.
Sealing system upgrade
The triple sealing structure (labyrinth + contact + air curtain type) is adopted, and the dust intrusion rate is reduced by 90%. After the renovation of a cement plant, the bearing failure rate dropped by 75%.
Cleaning system
Establish the "three cleans" standard: cleaning up materials before shift, cleaning debris in class, and cleaning oil pollution after shift. Equipped with special cleaning tools to avoid secondary damage.
Lubrication optimization
Choose grease according to working conditions:
High temperature environment: compound calcium sulfonate based resin
Humid environment: polyurea-based resin
Heavy-duty environment: extreme pressure lithium-based grease
Intelligent monitoring
Vibration sensors and temperature monitoring devices are installed to achieve early fault warning. A steel company has reduced unplanned downtime by 40% through this technology.
