Strategic alliance with wear parts expert

Through a strategic alliance, B&W provides advanced coal pulverizer replacement parts from Magotteaux, a leading supplier of high wear, severe duty castings and differentiated wear solutions. This supplier relationship combines the unique benefits of Magotteaux’s metallurgical expertise and experience in high wear, abrasion-resistant material with B&W’s expertise in coal pulverizer and boiler design, operation and optimization.

Xwin technology

Xwin technology combines the extreme high hardness of ceramic with the mechanical properties of high chromium metal for maximum wear resistance and wear life. Magotteaux’s Xwin technology is available for grinding rolls and grinding segments.

Benefits include:

  • extended running life
  • increased time between maintenance cycles
  • longer consistency of grinding profiles
  • extended duration of optimal pulverizer capacity and fineness
  • reduced power consumption

The results? Lower operating and maintenance costs, delivering up to 50% cost reductions

Gear Drive Babcock Wilcox

Gearbox Rebuilds and Exchanges

To maintain peak pulverizer operating conditions, systematic maintenance procedures are critical. In particular, gear drives can benefit from a comprehensive remanufacturing program to maintain high availability and optimize service life. We offer many services to support the operation of gear drive assemblies, including:

  • OEM replacement parts
  • Equipment upgrades
  • Remanufacturing services

After conducting in-depth inspections, a detailed report is provided that specifies the disposition of each gear drive component – parts are designated for replacement, refurbishment or reuse.

B&W can customize a gear drive remanufacturing program that includes all similar mills within a power generation system. We also offer a gear drive exchange program to meet the needs of customers that do not have excel mill capacity.

Roll Wheel Assembly

High dynamic loading of pulverizer components in an extremely abrasive environment will eventually limit the life of a roll wheel assembly.

Because operating conditions vary, there is no exact formula for calculating the service life of a roll wheel assembly. A comprehensive rebuild program is key to maintaining availability and maximizing the service life. After a thorough inspection process, each roll wheel assembly is returned to current design specifications.

We also offer a roll wheel assembly exchange program. Our in-stock roll wheel assemblies are completely re-manufactured and ready for immediate shipment.
