Vertical Spindle Roller Mill Coal Pulverizers Maintenance Parts Foster Wheeler MBF Coal Pulverizers are specifically designed for increased operating cycles and lower maintenance costs. FW supports all MB & MBF replacement parts and upgrades to suit customer individual needs. Replacement Parts: • Airports Upper & Lower • Eccentric Hubs • Rollers • Bearings • Oil Seals • Scrapers • Coal Shields • Roller Hubs • Segments • Plungers Testing & Field Service With 100 years of experience, our services include mill inspections and performance evaluations including off-site grinding roller rebuild and refurbishment. As part of our quality-focused commitment to continuously improve pulverizer operability and maintainability, several major design upgrades have been made available for both the MB and MBF pulverizers. These customized upgrades have assisted many of our customers in dramatically reducing maintenance budgets while improving profitability throughout the equipment’s long service life. Dynamic Pressurized Rotating Classifier The rotating classifier offers coal flow and fineness control using variable speed drive. This new design will greatly improve (10% to 30% output) and increase the efficiency with added flexibility to process varying types of fuel in existing mills. Rotating Airport Design Our latest improvement in MBF air-coal flow geometry reduces wear on the airport surfaces. The rotation of the port reduces wear in two ways: • Coal passes over the port opening and is swept upwards before it can be trapped in the interface between the rotating and stationary pieces. Older designed stationary airports require coal to travel over the interface where it can become trapped and cause wear. • The rotation of the ports reduces housing wear by spreading the wear more evenly over the entire periphery of the pulverizer. The 3-sided airport design results in a self-cleaning action of the gap area. These new airports are two-piece rotating airports. The lower airport segment will be made of cast iron while the higher wear upper airport will be made of cast chrome-moly abrasion resistant white iron. The upper airport will be designed for the fuel and is a simple bolt on design and can be changed quickly as fuels change. This design extends the total wear life and as a result, reduces the required maintenance hours and extends the parts replacement cycle. • High-Chrome Rollers and Grinding Table Segments Rollers and Grinding Table Segments have become our standard offering and have dramatically increased durations between required change outs. • Patented Profiled Roller that increases Fineness • Next Generation Ceramic Tires and Segments • Shim Style Plunger The improved design replaced the older cartridge style tensioner. This well accepted product has been lauded for its ease of retrofit onto existing pulverizers. This simplified design requires a minimum maintenance while providing easy adjustments required in order to optimize mill performance over the wear life of the grinding components. • Externally Adjustable Plungers • Individually Controlled Discharge Dividers Vane guided Discharge Dividers are designed to provide coal flow adjustment and distribution control to each conduit. As a reuslt, fine tuning of mill coal flows to each conduit and burner is now possible. This new technology combining Ceramics and Iron brings a higher wear resistance and durability over High-Chrome Roller. Expected wear life may be doubled for the same size roller. Ceramic is imbedded in the high wear surfaces in order to maintain an even profile longer and reduce roller vibration during operation. As a result, ceramic rollers will decrease wear of internal components and with it maintenance cycles. • High Chrome Roller Upgrades We offer a full range of steam generator equipment, aftermarket products and services to the power, industrial, and waste-to-energy sectors.
