ATRITA pulverizers are manufactured by
Riley Power Inc. They are high-speed mills
that operate from 900 rpm for the larger
machines to 1800 rpm for the smallest
machines. They are designed to pulverize awide range of fuels such as bituminous,
sub-bituminous, lignite, coke, and some
industrial by-products.
There are two standard ATRITA pulverizer
arrangements. A single type consists of a
crusher, a pulverizer, an internally
adjustable classifier and a fan section. A
duplex mill combines two single ATRITA
mills to form a duplex machine. Thecapacity ratings for the duplex are double
those of a single ATRITA mill of the same
size. ATRITA capacity ranges from 7000
lb/hr for a 350 single mill to 70,000 lb/hr
for the 558 Duplex mill. Duplex ATRITA
pulverizers began with the 550 single and
larger mills. Smaller sized pulverizers were
not designed as duplex mills.
The majority of the existing ATRITApulverizers consist of three sections:
1) crusher section
2) grinding section
3) classifier and fan section
Each is mounted on the same
horizontal shaft.
Each section is designed for a specific task
during the pulverization process. All sizes
feature the same pulverizer component
sections that perform the same function,
just varying in size and throughput. TheATRITA mill is driven with a single motor
that is coupled to the shaft either with
a direct drive high torque motor or
through a clutch. For most units, this is
a centrifugal style clutch that allows for
a slower start up.
ATRITA mills provide the advantage of
having a complete pulverizer mounted on
one shaft all driven by a single motor.While the frequency of required
maintenance is greater than other
pulverizer designs, the overall out of service
time is less and doesnt require specialized
tooling or rigging. For some ATRITA sizes,
many of the wear parts are
interchangeable. Utility boilers were
often supplied with a spare mill to
maintain boiler output during a mill outage.
ATRITA mills have a relatively small
rotating mass that enables shorter start
up times. They can also be brought on line
and removed from service quickly because
of the no coal reservoir design. Overall,
the simple design and operational logic
make the ATRITA pulverizer easy to operate
and maintain.

The customer
and Alstom
develop a list
of parts to be
included in
each kit.
Alstom then
ships these
parts in
pre-packaged
kit form to the
customer two
weeks prior to
the planned
outage or
rebuild.
Customer
withdraws
parts from the
kit, as needed.
Items not
needed from
any given kit
are shipped
back to
Alstom for

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 customers exclusive stock
inventory at the Regional Service Center
nearest the plant.
Replace
Rebuilt components are returned to acustomer when needed to replace a similar
component requiring service. The replaced
component is sent back to the Service Center
for rebuilding and restocking.

Alstom can supply new Rotor Assemblies or
rebuild existing assemblies incorporating
upgrades to address operational or
performance issues.
Alstom understands the demands placed on
plant operators to keep their pulverizers
operating at peak performance. Coupled
with the reality of greater spans between
outages and shorter outages, efficient and
timely equipment maintenance programs
are vital.
Alstoms Rotor Rebuild Programs, tailoredto customer requirements, follow a proven
process that includes disassembly and a
thorough inspection of all components.
Worn out parts are replaced or repaired as
appropriate, and upgrades included when
specified. All repairs, reassembly and
dynamic balancing are performed to
strict tolerances and procedures.
The result is a piece of equipment returnedto as-new condition and backed by a
comprehensive warranty.
Additionally, Alstom stands ready to work
with owners of ATRITA Pulverizers to
design a rotor spares program that meets
their specific goals.

Robotic
DoubleWeldOverlayHammers
Alstom continues to design and develop
products for ATRITA mills that will meet the
changing needs of our customers. Ourperformance and availability upgrades can
help when looking at fuel switching and the
changing environmental regulations. Alstom
provides solutions to improve fineness,
provide longer wear life, reduce
maintenance costs, eliminate a number of
mechanical problems and improve the
overall reliability of your mill.
Robotic Double Weld
Overlay HammersThe Alstom weld overlay is a chromium
carbide base electrode applied to the
standard swing hammers that significantly
increases wear life. This corrosion and
erosion resistant overlay contains a
chromium carbide content greater
than 18%, resulting in 60-62 Rockwell C
hardness that makes it capable of handling
severe impact applications.
Advantages
Significantly more erosion resistant than
the standard hand-applied overlay Weld can be applied to standard
manganese hammers
(existing customer inventory)
Robotic application ensures
part uniformity
Benefits to User
Up to double the operational wear life
longer periods between hammer
replacements Less component wear downstream
Longer component service life throughout
the mill
Improved fineness resulting in less
unburned carbon
Performance and AvailabilityUpgrades for ATRITA Mills

CT4 is a white iron alloy with a high
chromium content used in:
Wear plates
Crusher blocks
Breaker plates
Periphery liners
Fan blades
Fan bolt guards
CT4 is engineered to resist abrasion and
erosion in high wear areas of the mill.
Proprietary heat treating results in superior
hardness and toughness, and produces a
part that is less brittle, thus reducing the
risk of cracking during installation. In
addition, longer wear means better grinding
capacity and fineness for longer periods of
time resulting in an overall improvement in
mill operation and performance.
Advantages
Superior wear
Superior toughness
Less brittle resulting in less cracking
during installation
Benefits to User Extended operational life
Longer periods between
part replacements
