A wide range of modifications and upgrades are available for your B&W Roll Wheel™ roller-type or E/EL ball-and-race pulverizers. These new components and technologies can be retrofitted onto existing pulverizers to provide you with the latest designs and operating benefits which can increase availability and reliability and reduce maintenance.
B&W has extensive experience in grinding all types and blends of coals. All retrofit parts and materials are engineered and manufactured to the original specifications to ensure proper fit and performance.
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 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.
The results? Lower operating and maintenance costs, delivering up to 50% cost reductions
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:
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.
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.
