We fabricate and repair various types of
rolls and shafts for a range of
applications. The majority of our work
with shafts and rolls comes from food
processing machinery and industrial
material moving equipment.
One type of rolls that we service are
called sizer rolls, or conditioning rolls.
They form bulk semi-solid product into
sheets as it is fed between two of the
rotating shafts. Carbon steel pipe
comprises the core of these rolls, which
may vary in diameter and length.
Our machinist fabricators make and fit
the ends with lathe-turned, stainless
steel stub shafts with precision
fabricated spindles for bearing mounts.
We then cut keyways into the spindles
for securing drive gears or sprockets.
Custom-formed, stainless steel cladding
encases the body of these rolls, which
our fabricators weld at the seams and to
the stub shafts. This creates a complete
seal for sanitary food grade
applications. All welds along the roll
facing are ground smooth to meet product
tolerances.
Here at Specialty Welding, Inc. we also
refurbish and fabricate many other types
of equipment components that include
shafts and spindles. A broad spectrum of
commercial and industrial operations
employ material moving equipment for
bulk product handling, such as
manufacturers, processors, mining
operations, grain storage and packaging,
to name a few. We are equipped to repair
nearly any type of conveyor components
that can either be shipped to our
facility or are located within our field
services region.
Auger conveyors are another type of
shaft-based equipment used in several
industries. These move materials such as
steel shot, grains, various food
products, ores, ash, seeds,
fertilizer…the list is extensive. Augers
are effective for moving flakes,
powders, granular products, liquids and
much more.
Most of our auger conveyor refurbishment
work involves worn out flights and
damaged spindles. We fabricate
replacement flights by cutting sections
on our CAD operated
waterjet or plasma cutting table, then
welding them together to form the
helical blade. After repairing any
damage to the shaft surface, our
fabricators stretch the blade to correct
flight spacing and weld it to the shaft.
Worn or damaged stub shafts are removed
from the ends and replaced. These are
similar to those used in conditioning
rolls.
We can repair or fabricate new auger
conveyors in all shapes and sizes, made
from any type of metal. Our customers
may either ship their damaged augers for
repair, or send us specifications and we
will fabricate replacements. We may
quote lump sum pricing or charge for
shop time and materials, depending on
the nature and extent of work required.
