SWIF-MUL
ENGINEERED FOR TRUE MULLING ACTION
AND MINIMAL MAINTENANCE EXPENSE
Like other sand handling equipment, sand mulling machinery
is usually considered self-destructive. Swif-Mul solves this
maintenance problem while delivering completely mulled sand.
Those muller components subject to excessive wear can be
easily replaced during routine maintenance. Because of this
innovative concept, downtime is reduced to a minimum, and
high output is maintained for a greater return on the
dollars invested. All of this is packaged in a muller that
is simple in design, ruggedly built, economically priced,
and that delivers high efficiency performance.
SWIF-MUL is
Designed for More Efficient Mulling Action
Casting defects are generally caused by poor sand
properties. These defects are greatly reduced when molding
sands are mulled correctly. A true mulling action requires
each grain of sand to be evenly coated with clay and
binders.
Swif-Mul Mullers are engineered to supply the action and to
supply it regularly. The Swif-Mul mulling action "squeezes"
or "kneads" the mass of sand and clay between the mullers
and the base. An adjustable spring keeps the correct amount
of pressure on the mullers.
As the mullers revolve they cause a "smearing" action that
rolls the grains of sand into the clay. To insure thorough
mixing, sand plows aerate and continuously churn the entire
batch, blending the oil or water uniformly throughout the
sand. The result is a well-bonded "envelope" for each sand
grain, and excellent adhesion between the coated grains.
SWIF-MUL Reduces
Material Costs
Mulling ends the wasteful practice of discarding molding
sands considered expendable or irreclaimable. With the
addition of small amounts of new binders, catalyst, and oil
to oil bonded sand, or the addition of small amounts of new
binders and water to water bonded sand, a five or six minute
re-mull cycle can renovate sand for further casting use.
In re-mulled sand, as in freshly mulled sand, the correct
moisture content to prevent casting defects, and the correct
oil content to minimize smoke and fume emissions can be
achieved. These are moneysaving benefits - added to the
impressive savings in materials which results from the
simple practice of re-mulling molding sand.

Reduced Weight
Means Reduced Wear
In any machine, bearing wear and maintenance are directly
related to the weight of its moving parts. Swif-Mul has
engineered in durability by reducing weight. The light
weight aluminum alloy cross head carriage assembly and the
light weight muller wheels cause less strain and wear on
bearings and gear train.
Adjustable
Wheel Pressure
The wheel pressure can be changed by adjusting the flat
tension spring to apply a precise amount of pressure for
each specific mulling application. Clearance between the
muller wheel and base plate can be adjusted to handle
various grades of sand with utmost efficiency.
Protected Pivot
and Bearings
The double ball bearings in each muller wheel are totally
shielded and permanently lubricated. Seals protect both the
axle shaft and the muller bearings to provide maximum
bearing life. The pivot joints are enclosed by oil
resistant, bellow-type dust covers, giving the wheel joints
and moving parts complete protection from the abrasive
action of the sand. Multiple-lip sand seals located inside
the vertical drive shaft housing, prevent sand from entering
the drive shaft and cross head castings.
Adjustable Sand
Plows
Fully adjustable inner and outer sand plows are designed to
give maximum mixing action. All plows are hard surfaced
along the leading edge with a tungsten carbide layer applied
by the oxy-acetylene process. Abrasion resistant steel plows
are standard with all models.
Discharge Door Operates with One Hand
|
|
Opening the bottom
discharge door is an easy one-hand operation. The plow
action makes discharge automatic and makes the muller
practically self-cleaning. Discharge requires about ten
seconds. During the mulling cycle a seal ring prevents
leakage, and a simple cam lock "locks" the door. The
door is adjustable to compensate for normal wear. |

PM-250
Portable Muller
The Swif-Mul
PM 250 moves the convenience of portability right into
your foundry operation yet is able to deliver the same
efficient, heavy-duty service you expect from a stationary
muller.
Portability
and profits can move hand-in-hand. Many companies have
found that the increased convenience of wheeling the
muller from job site to job site, has been the difference
between profitable jobs and losers. And there can be more
numbers in the profit column because the efficiency of a
full-scale operation does not have to be sacrificed for
portability - the PM 250 has a big 200-275 pound capacity.
lt also has
heavy-duty engineering. This means performance you can
count on and the increased efficiency and profits which go
along with dependability.
The Swif-Mul
PM 250 puts many fine features on wheels
- Sealed,
anti-friction ball or roller bearings throughout.
- Abrasion
resistant steel plows, faced at wear points with a
smooth layer of tungsten carbide which is applied by
oxyacetylene torch.
- Abrasion
resistant, hardened steel crib and base liners for extra
life. Eight gauge thickness is standard.
- Radius edge
steel muller wheels are standard.
- Retractable
handles for added maneuverability.
- Convenient
chute height means convenient unloading wheelbarrow can
be rolled directly underneath.
- Rolls to
the job on 5.75 x 14 inch industrial type pneumatic
tires.
- Shipped
fully assembled and ready to go to work.
SWIF-MUL PORTO-UNIT
PM-125 Porto Unit
Wheel
convenience right into your small foundry operation with
the new Swif-Mul Porto-Unit. It is a heavy-duty cart
designed specifically to convert your ML 65 Swif-Mul or
your ML-125 Swif-Mul into a portable muller. Conversion is
a five minute job - remove eight bolts from the muller
legs, exchange the legs for the Porto-Unit, and replace
the bolts. Then you can wheel your muller to the job site.
It's simpler than moving your job site to the muller.
It is
constructed for durability with standard Schedule 40 black
iron pipe. The Porto-Unit wheels for the ML-65 are fitted
with eight inch, oil resistant rubber tires. The
Porto-Unit wheels for the heavier ML-125 are fitted with
ten inch, oil resistant rubber tires
