Introduction to the Alstom Pulverizer
In 1923 Combustion Engineering (CE)
acquired the Raymond Brothers Impact
Pulverizer Company considered one of the
nation’s leading manufacturers of pulverizing
and grinding equipment.
In 1933 CE introduced the CE bowl-type
pulverizer based on original Raymond
Brothers technology. Today this design
is owned by Alstom and with over
70 years of continuous development
and improvement Alstom
pulverizers are highly respected
within the power industry.
Alstom pulverizers span the
globe and have been built in
a variety of sizes and
capacities. We offer a full
line of parts, service and
solutions to help ensure
that your pulverizers
provide optimum
operation.

Grinding Rolls and Grinding Segments
Raw coal enters the pulverizer that
is combined with classifier
tailings and then fed into the
grinding zone. The
grinding zone consists
of the driven bowl
and three roll
assemblies. The roll
assemblies are
free to rotate on
the coal bed. A
spring imparts
thousands of
pounds of force to
the rotating
grinding roll.
This force causes the grinding roll to grind
the coal and reduce it in size. Both the
grinding roll and the bowl segments will
wear over time causing the pulverizer to
lose grinding efficiency.
Replacement grinding rolls and segments are
available in a variety of materials that will
maximize life and reduce downtime for
change out. Choosing the right grinding
surface material for your pulverizer will be
dependent on your coal properties. Alstom’s
experts can help you make the right choice.

XWIN® Grinding Roll and Grinding
Segment Technology
Maintenance on any piece of equipment
around your plant is a fact of life, but it
doesn’t have to be a continuous way of life.
Pulverizer grinding rolls and grinding
segments wear over time. Downtime for
replacement of bowl grinding segments and
grinding rolls means that your equipment is
not available for operation.
Alstom offers bowl grinding segments
and grinding rolls that exhibit a
wear life much greater than
chrome carbide overlaid grinding
rolls. This significantly extends
the pulverizer roll and
grinding segment life and
substantially lowers the
maintenance cost for
replacing these
components.
Xwin® grinding roll showing “honeycomb” design
Alstom’s pulverizer technology
is now combined with Xwin®
cast product technology for bowl
segments and grinding rolls. This
technology developed by
Magotteaux, Inc. has shown dramatic
results on Alstom RB pulverizers and has
also been applied to Alstom’s RS, RP, and
RPS shallow bowl pulverizers.
Xwin is a registered trademark of Magotteaux, Inc.
Magotteaux utilizes a metal matrix composite
(MMC) to produce the Xwin® grinding
segments and grinding rolls that are designed
to be superior to any other grinding roll or
grinding segment currently offered.
Xwin® grinding segments
This composite combines the extreme wear
resistance of ceramic with the mechanical
properties of cast alloys. MMC is composed of
ceramic particles imbedded and reinforced
with a high chrome alloy evenly distributed in
a honeycomb design.
Use of the new MMC results in reduced wear
and a higher resistance to breakage over
traditional monometallic grinding rolls.
The Xwin® grinding roll demonstrates a
considerable improvement in wear life,
better fineness, decreased spillage, lower
pulverizer amps and reduced wear on the
classifier components. The overall benefits
are improved performance, improved
efficiency and reduced operating and
maintenance costs.

Grinding Roll Hard
Surfacing Technology
As an alternative, grinding rolls can be
resurfaced using COMBUSTALLOY Chrome
Carbide Weld Wire (CE52 & CE92) or hybrid
heavy tread, a tungsten carbide weld.
Applying the best wear material in the
highest wear areas helps assure the longest
life from the roll while keeping costs down.
Summary
Alstom offers a variety of options for
replacement grinding rolls and grinding roll
surfaces. Whether you choose a complete
grinding roll replacement or elect resurfacing
there are several wear-resistant options that
are designed to extend the wear life of the
grinding roll. The results include better
fineness, decreased spillage, lowering
pulverizer amps and wear on the
classifier components. Your benefits are
improved performance, improved efficiency
and reduced costs.

FLOW-PRO Vane Wheel
Vane wheel technology was originally
pioneered by Alstom and has been in use
for over 25 years.
Prior to the use of a vane wheel Alstom
pulverizers utilized three fixed openings to
admit primary air to the area above the bowl.
Coal settling out, high wear areas and poor
distribution to the classifier were all factors
that led to the advent of the vane wheel.
Through careful computational flow
modeling (CFM) Alstom has been
able to continuously improve the
vane wheel assembly.
As illustrated in the CFM for
the original vane wheel
design, there are low
velocities in the upper
body with good mixing in
the mid and upper body
area, good classification
in the lower body area
and even distribution to
the classifier area.
The model also
illustrates that there are
high velocities above
the vane wheel vanes
that can lead to localized
wear and recirculation of
coal/air in the vane area.
Flow Modeling for Original Vane Wheel Design
Alstom has developed a new primary
classifier, the low profile FLOW-PRO
Vane Wheel, to manage the critical air and
coal mixing occurring around the outer
diameter of the bowl. The FLOW-PRO
Vane Wheel retains the time proven flow
patterns through the pulverizer with reduced
wear and greater simplicity.
This is achieved by lowering the deflector
liners of the classic vane wheel from the zone
where the coal has been entrained by the
airflow down to the elevation where the air
meets the coal. The lowered deflector liners
catch the primary air (PA) flow while it’s still
clean and redirects it inward over the bowl
rim where it entrains the coal. The coal is
rolled immediately back over the bowl and
decelerated to allow the large particles to
drop back to the table for further
pulverization. The remaining smaller coal
particles are directed up through the separator
body at relatively low velocity for reduced
wear, enhanced drying and improved
classifier efficiency.
Flow Modeling for FLOW-PRO Vane Wheel Design

Features
• Deflector liners are located down in the
clean air region for reduced wear
• 360 degree flow path for even flow
distribution to the classifier
• Promotes reduced velocities for reduced
down stream wear
• Coal flow patterns are kept off the mill body
virtually eliminating body wear
• The flow control gap between the rotation
and stationary components is out of the
erosion zone
• Wingtips retained for efficient air velocity
and spillage control
• The small size and steep angle of
the deflector liners do not
provide any coal hide out
areas
• A selection of wear
materials and vane
wheel attachment
methods are
available
Benefits
• Increased
pulverizer
availability
• Reduced
maintenance
costs
As illustrated here,
the new FLOW-PRO
Vane Wheel incorporates
a resized deflector along with
high-grade liner materials for the
deflector, vane and wing tips. The
CFM and the force and velocity analysis
illustrate more uniform flow velocities that
substantially reduces localized wear.

Advanced Static Classifier
The final path the coal takes before leaving
the pulverizer is through the classifier
section. While using well-maintained grinding
rolls and grinding ring segments
and ensuring the correct velocities through
the vane wheel are critical to pulverizer
performance, the classifier is equally
important to pulverizer performance.
Alstom’s advanced static classifier (ASC)
has been developed through computer
flow modeling at its Power Plant
Laboratory. The ASC has been
modeled to improve classifier
efficiency. Better fineness
control has been achieved
while maintaining the
same pressure drop.
Fineness testing has
proven that the amount
of 50 mesh particles
has been reduced.
For high wear areas
on the ASC, Alstom
offers such options as
DYNAWEAR II
Vacuum Bonded
Ceramics, AR Plate
and CROWN 700
Castings. The ASC is
currently available for all
Alstom pulverizer types
and sizes.
The ASC is designed to provide better fineness
classification and improved efficiency through
calculated window height and length
dimensions, an extra deflector ring and new
profile classifier blades. The improved fineness
occurs at the same classifier settings with
lower pressure drops. The ASC’s components
are supplied in wear-resistant materials
resulting in increased service life.

Exhauster Products
RB, RS and RPS pulverizers use exhausters
to transport the coal from the pulverizer to
the boiler. Following the coal path in the
pulverizer the next area of coal contact is
the exhauster section.
Alstom can supply
fully assembled,
dynamicallybalanced
exhauster wheel
assemblies ready

Exhauster Fan Bearing Housing Cooling System
Exhauster fan bearings typically operate in an
oil bath condition without the aid of oil
filtration or cooling. These bearings are
exposed to extreme duty conditions especially
as the exhauster fan components begin to
wear. The life of the bearings is highly
dependent on the temperature at which they
are operated and the condition of the
lubricating oil in the bearing housing.
Alstom offers a bearing housing
cooling system retrofit for your
exhauster to help increase the life
of exhauster fan bearings.
Features

Horizontal Pivot Scraper Upgrade
Alstom’s horizontal pivot scraper assembly
is an improvement over other pyrite scraper
designs because of enhanced operation and
service life. It is easier and safer to install
and maintain, and can be installed as a
replacement with little or no rework of
existing parts.
Traditional scraper assemblies use vertical
mounted bushings that tend to wear and
allow the scraper to droop and wear directly
on floor liner. Alstom’s design moves the pivot
from the floor area to a horizontal position
above the mill bottom.

The improved assembly support allows the
scraper to do a better job clearing debris from
the mill bottom. The torsion spring provides
enough resistance to move debris from the
mill bottom, but also allows the arm to fold
back over larger immovable objects such that
neither the assembly nor the rest of the mill
are damaged. The new horizontal scraper
design eliminates the task of removing the
entire assembly as a unit from the mill to
replace wear parts.
The original scraper design had an assembly
weight of about 150 pounds, the new
design allows individual components
weighing about 30 pounds to be replaced.
This means quicker, safer servicing of
the scraper assembly.
Split Bearing Race Retainer
Alstom’s split bearing race retainer can be
installed without costly bowl hub removal. It
is supplied in two halves that are clamped
around the main vertical shaft. Two trim drive
brackets are supplied with the split bearing
retainer and are located below the bowl hub
to prevent the split bearing retainer from
moving upward.
The inner race retainer prevents the inner
race from creeping up the main shaft. The
split bearing retainer also functions as a wear
sleeve for the oil seal. The oil seal no longer
runs against the main vertical shaft
eliminating any wear on the main vertical
shaft that could lead to costly down time for
shaft replacement or repair.

HP Pulverizer Journal with
Double Upper Bearings and Spring
RB Pulverizer Journal and Spring
RP Pulverizer Journal and Spring

Double Upper Bearing Journal Assemblies and Upgrades
The double upper bearing assembly replaces
the single upper journal bearing with two
tapered roller bearings. This improved design
increases the radial capacity design of the
upper bearing and reduces thrust loads on the
lower bearing resulting in an increased life for
both bearings.
The double upper bearing assembly was
designed through an intensive engineering
analysis of pulverizer journals under actual
operating conditions. Utilizing field data
collected from several pulverizers, journal
loadings were accurately determined by
computer analysis. This allowed the final
bearing selection and location to be
optimized. As a result the
loadings for both the upper
and lower bearings
were decreased.
The double upper
bearing journal
design also
includes improved
oil and air seals
for protection
against
contamination
of the journal
bearing lubricant.
The double upper
bearing journal is
available as an upgrade
to an existing journal
assembly. It can also be
supplied as part of a new journal
shaft assembly or the entire journal can
be replaced as an assembly.

Journal Spring Rebuilds and Upgrades
Alstom Service Centers can rebuild journal
springs and incorporate upgrades designed to
suit your operating requirements.
Alstom offers an upgraded journal pressure
spring for 963 – 1003 RP pulverizers
equipped with the small separator top. They
have been designed to prevent failure of this
component from stress fatigue.
A pressure spring failure leads to uneven
loading on the bowl assembly, and if
uncorrected, will lead to the failure of the
main vertical shaft.
The spring itself has been redesigned to lower
stress on each coil at the same compression.
A new bellows protects against coal leaks and
allows greater visibility of spring oscillation.
R 3 Component Rotation Programs
Alstom offers customers
a systematic method for
rebuilding boiler related
equipment and
returning this
equipment to service.
Alstom’s Regional
Service Centers are the
focus of this program
combining their extensive
inventory, rebuild portfolio
and proven processes to
provide a unique service.
The R 3 program is based on
Rebuilding, Restocking and
Replacing components.
Rebuilding
Complete disassembly and inspection of a
component takes place. Worn out parts are
replaced and components repaired. The
components are rebuilt to strict procedures
and tolerances. Upgrades to components
can be included.
Restock
Once a rebuild is completed the component is
placed in the customer’s exclusive stock
inventory at a Regional Service Center nearest
the plant.
Replace
Rebuilt components are returned to a
customer when needed to replace a similar
component requiring service. The replaced
component is then sent back to the
Service Center for rebuilding and to
continue the process.
Rebuilding is an economical alternative to
buying new equipment. Rebuilt equipment is
kept at an Alstom location until needed freeing
up plant storage space. The process eliminates
down time waiting for a component to be
rebuilt and placed back in service. Pulverizer
components that are available in this program
include journal assemblies, grinding rolls,
gearboxes and worm shaft assemblies.
