2. 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.
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.

3. 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
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
• 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.
