Joy Mining
Machinery
Maximizes
Underground
Feeder-Breaker
Production with
Integrated Tailpieces,
Stability Jacks
Wednesday, March 16th, 2011
Underground Feeder-Breakers from Joy Mining
Machinery can now be equipped with integrated belt
tailpieces and stability jacks. Both of these new features
are designed to increase the productivity and safety of
mining operations and assist Joy Mining Machinery
customers to continue producing at the lowest cost per
ton over the life cycle of the equipment. Specific benefits
of these design features include:
Productivity
• Shorter conveyor belt move time
• Higher coal production due to quicker conveyor belt
moves
• Improved conveyor belt-to-Feeder-Breaker alignment
results in more productive transport of mined materials
Lowest cost per ton
• Improved conveyor belt-to-Feeder-Breaker alignment
results in minimal material spillage at Feeder-Breaker to
conveyor belt transfer point
• No need to anchor Feeder-Breaker tailpiece to mine
roof, floor and ribs; Feeder-Breaker with stability jacks
(roof beam supports) has sufficient traction to pull the
conveyor belt
• Conveyor belt moves possible with one worker instead
of the two or more workers needed to move Feeder-
Breakers and separate tailpieces
• The two or three additional pieces of equipment that
would normally be required to move a separate belt

2. tailpiece are freed for use in other jobs during conveyor
belt moves
• Easy installation of conveyor belt structure into the
Feeder-Breaker mounted tailpiece due to replacement of
manual belt handling with belt handling devices
Safer Operation
• Safer belt moves
• Stronger anchoring method
• The belt is trained so that it runs straight, resulting in
less spillage and safer operation
Seeking to improve its longwall panel advancement rate,
a mine in the United States recently purchased two JOY
BF-14A-59-64C Feeder-Breakers with mounted
tailpieces and has enjoyed increased productivity due to
quicker conveyor belt moves. Joy engineers in
Millersburg, Kentucky designed the Feeder-Breakers
with mounted tailpieces, which eliminate the need to
anchor the tailpieces to the mine floor, roof or ribs. The
Feeder-Breakers are also equipped with roof beam
supports (stability jacks) that stabilize the Feeder-
Breakers and belt tailpieces and protect them from the
high tension associated with moving several thousand
feet of belt. When a conveyor belt needs to be moved,
the Feeder-Breaker roof beam supports are lowered
from the roof and the Feeder-Breaker trams toward the
mine face, pulling the panel conveyor belt as the
Feeder-Breaker advances. When the conveyor belt has
reached its new location, the Feeder-Breaker roof
supports are anchored back into the roof. The Feeder-
Breakers are processing up to 1,200 tons (1,090 tonnes)
per hour.
The Feeder-Breakers are equipped with many other
upgrades and features that are designed to allow
customers to achieve lowest-possible-cost-per-ton
production and increased productivity. These upgrades
and features include belt spreaders and highly-rated
crawlers with maximum draw bar pull, direct-drive
breakers that reduce wear on components such as
chains and sprockets, 18-inch (460-mm) reverse
crawlers that provide maximum torque operation at low
speed and are very well suited for conveyor belt
structure pulling, three-way dumps for shuttle car
unloading, 3.5-inch (89-mm) pitch conveyor chains, and
umbilical remote trams.
