Product Description
PD
(TBI)
1 of 1
The Tru-Balance In-Line Sifter is designed to be used in a pneumatic conveying system. The Sifter removes
oversize impurities. It is usually floor mounted, but can be attached to the ceiling.
The Sifter is designed for easy inspection, cleaning, and maintenance. Sieve frames are nested one on top of the
other between an upper and lower dome. The stack of sieves is held together with a clamping system and draw
rods, creating a pressure tight vessel.
Each sieve frame holds a lift-out tray that has the appropriate sieve screen. The screen is stretched and glued for
best performance and reasons of sanitation. The sieves are sealed by O-rings and the trays are sealed with flat
gaskets.
The Sifter is operated by a motor(s) mounted on the frame, V-belts, and counter-balancing weights on eccentric
shafts synchronized by a tie-bar.
Flow Scheme Description
FSD
(TBI)
1 of 1
The Tru-Balance In-Line Sifter works like a multi-sieve gravity flow Sifter except that it operates in a pressure or
vacuum pneumatic conveying system. The product is gently sieved without being forced through the screens by
the conveying air and without any mechanical beaters or impellers. The air is “filtered” separately from the
product to ensure that no oversize impurities can bypass the protection of the Sifter.
As the product is conveyed into the Sifter inlet, it enters an expansion chamber. As its velocity decreases, the
product loads the uppermost sieve frame(s). The large volume of the expansion chamber causes the incoming
product to lose conveying velocity and the product naturally begins to separate from the conveying air. As the
product settles out from the low velocity air, it contacts the screens and sifting begins immediately.
The product forms a layer on the Sifter screens and creates a resistance to the flow of air through the screens.
The conveying air seeks the path of least resistance, which is found through the air bypass (ABP) screen
positioned directly above sieve 1. The air bypass screen is typically covered with the same screen mesh that is
used for sieving the product but acts more like an air filter than as a sieve. The filtering effect of the air bypass
sieve ensures that no oversize impurities can bypass a screen of the required mesh size.
The chamber above the air bypass screen is connected to the two side channels common to all of the lower
intermediate sieve frames. The “filtered” low velocity conveying air travels down these side channels and joins
the freshly sifted product. The product is conveyed out of the Sifter once this mixing occurs. The unique air
bypass arrangement actually allows the air pressure to equalize on both sides of the sifting screens so there is no
pressure differential that would force product through the sifting screen.
As the product is gently sieved, it falls on a stainless steel sieve pan. The sloping pan is designed to gather and
direct the sieved product to the two channels on each side of the sieve frames. The sifted product joins the
bypassed air and falls to the lower dome of the Sifter. Product that was not able to pass through the screen is
conveyed on to the next sieve until all of the desired fine particles are removed. The oversize impurities are
conveyed to the sealed tailings container.

Vibration-Sensing Switch
VSS
(TBI)
1 of 1
The vibration-sensing switch is an added safety feature of some models of the Tru-Balance In-Line Sifter. When
properly adjusted, the switch detects out-of-balance conditions, minimizing damage to the Sifter. This device
contains an internal switch that activates when there is vibration or shock above a pre-set level.
Connecting the Switch
□
Carefully read the included instructions before installing the vibration-sensing switch. The switch must be
connected to the motor controller in accordance with existing electrical codes.
□
The switch should be connected to stop the Sifter immediately upon activation.
Adjusting the Switch
□
The vibration-sensing switch arrives pre-set. Under normal operating conditions, it should not need adjusting.
However, should adjustment be needed, Great Western recommends adjusting the switch so that the Sifter
is just able to start without tripping the switch.
□
Turn the set point adjustment screw clockwise 1/4-turn to further decrease the sensitivity of the unit.
Turning the set point adjustment screw clockwise decreases the sensitivity to
vibrations, while a counter-clockwise turn increases the sensitivity.
Low-Pressure Switch
LPS
(TBI)
1 of 1
The low-pressure switch is a standard component of the Tru-Balance In-Line Sifter equipped with a pneumatic
clamping system. The switch arrives pre-set in the pneumatic control box. It is intended to function with a
programmable logic controller. The switch provides both normally open and normally closed contacts limited to
the current rating specified in the Pneumatic Connections section of this manual, and must be wired in
accordance with existing electrical codes.
Normal operating pressure for the Sifter is between 100 and 120 psi. Some systems may require a booster to
maintain adequate air pressure. If pressure falls below 80 psi, the switch will cause the Sifter to shut off or sound
an alarm.
If the Sifter suddenly shuts off due to inadequate air supply:
□
Check air supply and air line.
□
Re-establish adequate air pressure.
□
Initiate start-up procedure and continue operation.
Microswitches for Lift-Off Shields
M
(TBI)
1 of 1
Lift-off shields equipped with microswitches are an added safety feature of some models of the Tru-Balance InLine Sifter.
The microswitches on the lift-off shields must be connected to the motor controller in accordance with existing
electrical codes.
The microswitch prevents the Sifter from running when the lift-off shields are not installed. They may also be
wired to shut off the Sifter and/or sound an alarm when the lift-off shields are removed or become improperly
aligned during operation.
If the Sifter will not run, or the microswitches shut off the Sifter and/or sound an alarm:
□
Ensure the lift-off shields are properly installed.
□
Initiate start-up procedure and continue operation.
Proximity Switch for Tailings Container
PSTC
(TBI)
1 of 1
A proximity switch, located in the tailings container, is an optional component of the Tru-Balance In-Line Sifter.
The switch is designed to notify the operator that the level of waste in the tailings container has reached a predefined threshold. It can be wired to shut the Sifter off or sound an alarm. It must be wired in accordance with
existing electrical codes.
The switch system consists of a mounting well and proximity switch: the mounting well screws into the tailings
container lid; the proximity switch screws into the mounting well.

Compressed Air Discharge
CD
(TBI)
1 of 1
The pneumatic clamping system of the Tru-Balance In-Line Sifter remains active even when the electrical system
(i.e., motor) is locked out. This arrangement makes it possible to safely release and clamp the sieve stack.
If a requirement exists to work on the pneumatic clamping system, it must be depressurized. Check valves that
assist during normal operation may cause the pneumatic clamping system to retain pressure in the lines and
cylinders even after the Sifter is disconnected from the air supply.
Depressurize the pneumatic clamping system using the procedures listed below:
□
Lock out the Sifter’s electrical systems. Follow your employer’s plant safety guidelines.
□
Raise the top dome of the Sifter by turning the pneumatic control key to the released position.
□
Disconnect the compressed air supply.
The air supply may be effectively disconnected from the Sifter by using a locking
ball valve mechanism.
□
Lower the top dome of the Sifter by turning the pneumatic control key to the clamped position.

One person can lift and remove the sieves; however, two people work best.
The nested sieves are stacked on top of each other above the bottom dome. The sieves are numbered in order,
with the number “1” at the top of the stack. A separate air bypass (ABP) frame must be stacked above sieve 1.
□
For cable clamping systems, release the discharge hose coupling.
□
Remove the draw rods located around the perimeter of the sieve frames.
□
For pneumatic clamping systems, turn the Pneumatic Control Key to the unclamped position.
□
For cable clamping systems, release the two cable clamping devices by loosening the cable take-up shaft in a
counter-clockwise direction. This procedure will lower the bottom dome.
Do not loosen one side of the cable clamping system all the way; loosen one side
part way and then the other side, or both sides simultaneously. Continue until the
bottom dome is completely lowered.
□
Move to the opposite side of the Tru-Balance In-Line Sifter from which you will remove the sieves.
□
A sieve slide comes with the Sifter and helps
prevent damage to the sieve screens. Raise
the air bypass (ABP) sieve and carefully
insert the sieve slide with the lip of the sieve
slide down. The lip will stop the sieve slide
from moving as you remove the sieve from
the Sifter.
Photo 1: Initial Sieve Removal Procedure
□
Remove the ABP sieve. Continue removing sieves, one at a time, using the sieve slide.
When removing sieve frames, be careful not to drag the sieve frame on the sieve
below. This can damage the screen on the sieve below.

One person can lift and replace the sieves; however, two people work best.
□
If the lift-out trays were removed from the sieve frames during the sieve removal process, they must be
replaced before replacing the sieves.
When inserting the lift-out trays into the sieve frames, ensure the tray locks with
the throat on the sieve frame to make a complete tray-to-sieve frame seal.
Photo 1: Tray Insertion Procedure
With the lift-out tray properly inserted in the bottom dome, sieve replacement can be accomplished.
□
Place the sieve slide on top of the bottom dome. Insert the slide on the same side of the frame from which
you will be inserting the sieves. The slide lip must point down. The lip will stop the slide from moving as you
push the sieve into the Tru-Balance In-Line Sifter.
When replacing the sieve frames, be careful not to drag the sieve frame on the
sieve below. This can damage the screen on the sieve below.
□
Carefully place the highest numbered sieve on top of the sieve slide.
□
Gently push the sieve across the sieve slide making sure not to rock the sieve frame. This will prevent
damage to the screen on the sieve below.
Sieve Replacement

Inspect the sieve frames to be sure they are nested together properly. Make adjustments as necessary. The
sieves are nesting properly when the arrows on the top and bottom domes are lined up with the arrows on
each of the sieve frames.
The air bypass (ABP) sieve should be the last sieve installed in the sieve
replacement process.

To complete the sieve replacement process, see the appropriate section of this manual (Pneumatic
Clamping or Cable Clamping) for detailed instructions.
Pneumatic Clamping
PC
(TBI)
1 of 2
The sieve stack is clamped by a combination of pneumatics and draw rods. Correct installation of the draw rods
is critical to obtain a proper clamping of the sieve stack. If the sieve stack is not clamped tight enough, leaks will
occur. Additionally, the sieve stack could become excessively loose and disengage from the machine. If the
sieve stack is clamped too tight, dome/sieve failure and premature gasket wear may occur.
Do not place fingers near the top or bottom of the sieves during the clamping
operation.
□
Ensure that all of the sieves in the sieve stack are properly arranged.
□
Reattach the back shield to the Tru-Balance In-Line Sifter.
□
Turn the pneumatic control key to the clamped position. The top dome will lower.
Ensure that a minimum of 100 psi and a maximum of 120 psi of compressed air is
available at the Sifter.
While the top dome is lowering, ensure that the top dome and the air bypass (ABP)
sieve frame properly nest together. (Slight manual position alignment of the ABP
frame may be necessary).
Each pneumatic cylinder in the system is equipped with a control valve to ensure
uniform movement of the top dome during compression. If the movement of the
top dome is not uniform during compression, adjustment of the control valve may
be necessary.
□
With the sieve stack pneumatically compressed, install the draw rods on the outer perimeter of the sieve
stack.

Manually tighten the draw rods using a torque wrench and 1-1/4” socket. Do not
use an impact wrench for this procedure. Impact wrenches apply torque too
rapidly and unevenly for this precise application.
Keep the draw rod threads and the bottom side of the draw rod nut lubricated with
an anti-seize lubricant to ensure that 30 ft-lbs of torque is applied with little
frictional loss.
□
Tighten the draw rods using an “X” pattern: front-to-back and side-to-side; similar to the manner used in the
proper tightening of an automotive wheel. Continue this operation until all draw rods torque to 20 ft-lbs.
Several passes around the Sifter using this technique may be necessary before all the draw rods reach this
torque value
□
Adjust the torque wrench to 25 ft-lbs and repeat the above procedure until all the draw rods reach this value.
□
Finally, adjust the torque wrench to 30 ft-lbs and tighten the draw rods using the same “X” pattern. Once 30
ft-lbs of torque is achieved using this procedure, the Sifter is properly clamped and no leaks should be
evident. This technique and procedure will also reduce Sifter damage and premature wear.
□
After completion of these clamping steps, the Sifter is ready for operation.
The pneumatic control key should be removed prior to operation of the Sifter. This
action will prevent operation of the pneumatics while the machine is in operation.
Adjusting the Control Valve
Each pneumatic cylinder in the system is equipped with a control valve to ensure uniform movement of the top
dome during compression.
A silencing mechanism, incorporated in the valve’s design, provides for sound reduction of the pneumatic cylinder
exhaust.
An adjustment screw is used to control the rate at which the pneumatic cylinder exhaust is restricted.
A retaining ring on the control valve is used to prevent the adjustment screw from moving during operation.
The edges of both the adjustment screw and retaining ring are knurled for easy grip.
Cable Clamping
CC
(TBI)
1 of 2
The sieve stack is clamped by a combination of cables and draw rods. Draw rod and cable hold-down tightening
procedures are critical to obtain proper clamping of the sieve stack. If the sieve stack is not clamped tight
enough, leaks will occur. Additionally, the sieve stack could become excessively loose and disengage from the
Tru-Balance In-Line Sifter. If the sieve stack is clamped too tight, dome/sieve failure and premature gasket wear
may occur.
Manually tighten the draw rods and hold-down shafts using a torque wrench and
1-1/4” socket. Do not use an impact wrench for this procedure. Impact wrenches
apply torque too rapidly and unevenly for this precise application.
Keep the draw rod threads, the bottom side of the draw rod nut and the hold down
shafts well lubricated with anti-seize lubricant to ensure the 30 ft-lbs of torque is
applied with little frictional loss.
□
When all the sieves are in place, tighten the two hold-down shafts to 20 ft-lbs. This will raise the bottom
dome. Do not tighten one hold down shaft all the way. Rather, tighten one side part way and then the other.
This will prevent binding of the system.
Maintain proper alignment of the top dome and air bypass (ABP) sieve during this
tightening procedure.
□
Replace the draw rods on the outer perimeter of the sieve stack.
□
Tighten the draw rods using an “X” pattern: front-to-back and side-to-side similar to the manner used in the
proper tightening of an automotive wheel. Continue this operation until all the hold down shafts and draw
rods torque to 20 ft-lbs. Several passes around the Sifter using this technique may be necessary before all
the nuts reach this torque value.
□
Adjust the torque wrench to 25 ft-lbs and repeat the above procedure until all the draw rods and hold down
shafts reach this torque.

□
Finally, adjust the torque wrench to 30 ft-lbs and tighten the hold down shafts and draw rods using the same
“X” pattern. Once 30 ft-lbs of torque is achieved using this procedure, the Sifter is properly clamped and no
leaks should be evident. Additionally, this technique and procedure will also reduce Sifter damage and
premature wear.
□
After completion of these cable clamping steps and reattachment of the discharge hose, the Sifter is ready for
operation.

Tailings Container
TC
(TBI)
1 of 2
A sealed tailings container must be part of the system. The container is a place to accumulate oversize particles.
The container must be checked often to ensure it is not full.
Most Tru-Balance In-Line Sifters are configured with a cylindrical tailings container. However, some smaller
Sifters of this type are equipped with a tailings drawer.
If the tailings back up into the Sifter, it can become unbalanced and impart damage
to the Sifter.
The connection from the Sifter to the tailings container must be airtight; even a
small leak will cause the container to fill with good product.

Safety Relief Valve System
SRVS
(TBI)
1 of 2
Do not operate the Tru-Balance In-Line Sifter without the safety relief valve
properly installed.
To protect the Sifter from overly high pressure conditions or extreme vacuum conditions, it is equipped with a
safety relief valve. The valve is installed on the top dome and includes an outlet fitting and clamp.
The pressure device has a calibrated spring that provides the correct resistance on the safety relief valve. The
pressure device is made so it releases at a maximum of 15 psi for positive pressure systems, and −8 psi for
negative pressure or vacuum systems.
□
Before installing the valve, clean the inside of both the dome and outlet fittings with a dirt-free rag.
□
Lightly grease the inside of the fittings and the O-rings on the valve with a clean lubricant.
Positive pressure systems have a spring-loaded safety relief valve labeled
“PRESSURE UP” on the valve face. The “PRESSURE UP” label must be showing
when the opposite end of the valve is put into the fitting on the top dome.
Negative pressure or vacuum conveying systems will have a spring-loaded safety
relief valve labeled with the words “VACUUM DOWN” on the valve face. The
“VACUUM DOWN” label must be directed downward when the valve is put into the
fitting in the top dome.
□
Push the valve into the fitting; ensure the center ring on the valve is parallel to the face of the fitting.
□
Install the outlet fitting and the clamp.

The lift-out trays used in the Tru-Balance In-Line Sifter have screens that are mechanically stretched and then
glued to the frame. This method of attachment results in a more uniformly and highly tensioned screen, which
improves sifting performance. This method is also more sanitary than conventional methods of attachment.
When it is necessary to replace the screens or the screen cleaners due to wear or damage, two alternatives exist:
•
The first alternative is to return the trays to Great Western for replacement. Great Western will
remove the old screens and cleaners, clean the tray, and replace the screens and cleaners.
•
The second alternative is to purchase a mechanical stretcher, allowing for on-site screen
replacement. The equipment required is relatively easy to operate. Great Western can provide the
equipment and supplies for this option.

The original tie-bar equipped on a new Sifter will arrive from the factory preadjusted; however, replacement tie-bars will need adjustment.
Installing the Tie-Bar
□
Loosen the set collar.
□
Position the tie-bar (with the throw blocks attached) under the Sifter and lift towards the Sifter from both ends.
□
Slide the throw blocks on to their respective shafts; ensuring that the key slot located in the throw block aligns
with the key located in the shaft.
□
Continue to slide the throw blocks up the shafts until the bottom of each shaft and the bottom of each throw
block are flush.
□
Securely tighten both throw block clamping bolts as shown in Photo 2.
Adjusting the Tie-Bar
The preferred method for adjusting the tie-bar consists of aligning and adjusting the length of the tie-bar.
□
Adjust the tie-bar using the counterweights to rotate the Sifter to top dead center position, allowing the tie-bar
to adjust itself to proper length. Tighten the set collar and rotate Sifter by hand. The Sifter should freely
rotate.
If tight spots in the rotation are detected,
first inspect the tie-bar assembly for
possible problems.
If no apparent
physical problems exist, perform the
following alternate tie-bar adjustment
procedure:

With the counterweights properly positioned parallel towards the rear of the Sifter and the throw blocks
pointing to the right, place a straight edge that is long enough to span the width of the Sifter across both of the
throw blocks. This straight edge placement is depicted in Photo 3.
The tie-bar is properly adjusted when the straight edge is flat against both throw
block edges.
□
Adjustment of the length of the tie-bar may be necessary to align the tie-bar. One end of the tie-bar is
equipped with a split set collar. This is the side from which the length adjustment takes place.
□
Loosen the socket head screw located in the set collar with a socket wrench. This will adjust the length of the
tie-bar.
□
After performing the tie-bar length adjustment, check the alignment with a straight edge as described above.
□
When the alignment is correct, retighten the socket head screw located in the set collar with a socket wrench.
□
Check for freedom of rotation.
□
If the above procedures fail to bring the tie-bar into proper adjustment, the frame may be damaged. Contact a
Great Western representative for further technical assistance.
Maintenance
Great Western recommends lubricating the bearings on the ends of the tie-bar a minimum of every 60 days
and/or per plant maintenance schedule.
Sifter Balance
SB
(TBI)
1 of 1
The Tru-Balance In-Line Sifter was assembled and tested at the factory before shipping and has been balanced
to minimize vibration. If, after installation, the Sifter does not run smoothly, review the Vibration
Troubleshooting section of this manual for a listing of the most common causes.
Some of the typical balance problems that occur during installation and initial start-up are:
•
The mounting platform could be too weak for the Sifter and its load.
•
The Sifter is not securely fastened and leveled to the floor or ceiling.
•
The tie-bar is out of adjustment.
•
The lift-out trays are not in the Sifter.
•
The Sifter has become overloaded.
Troubleshooting
Always lock out motor.
Never run the Tru-Balance In-Line Sifter without the guards.
Never run the Sifter without the sieve frames and trays.
Don’t start the Sifter without notice.

Vibration Troubleshooting
VT
(TBI)
1 of 2
When the Sifter is producing excessive vibrations, first identify whether it is due to an imbalance or a mechanical
problem; this can normally be done by simply grasping the frame. If the frame has a shock or mechanical jolt with
each revolution, it is probably not out of balance. If the frame feels solid but has a swaying or pulling feel, then it
is out of balance.
A list of probable causes of excessive Sifter vibration, in the sequence generally found to be the cause, follows:
•
Faulty Bearings in Tie-Bar: If there is significant movement or play in the bearing, or if you can tell the
bearing itself is loose, the bearing should be replaced.
•
Improperly Adjusted or Installed Tie-Bar: Follow the instructions for the type of tie-bar installed on your
Sifter. Throw blocks should always be installed flush with the bottom of the shaft. Once the tie-bar is installed
and tightened, the Sifter should be revolved by hand. The movement should be uniform with no tight spots or
binding feeling. See the Removing, Installing, Adjusting and Maintaining the Tie-Bar section of this
manual.
•
Accumulation of Material in the Sifter: The increased weight of product accumulated in the Sifter will cause
it to be out of balance. This is checked and corrected by opening the Sifter and removing the sieves. Clean
out and re-install the sieves.
•
Loose or Broken Weight Bucket Keys: A full-sized key is used to hold the weight bucket in the proper
position on the drive shaft. Occasionally the key can wear the bucket knuckle, causing the bucket to shift
slightly and cause the Sifter to vibrate. This is checked and corrected by loosening the weight bucket, prying
it up, and observing the key; if the key is worn or broken, replace the key and securely tighten the bucket. If
the knuckle is worn, the bucket should be replaced.
•
Improper Leveling or Loose Mounting: The Sifter should be level on the floor or mounting platform. On
installation, shims should be placed under legs. The anchor bolts should not be used to pull the legs down to
the floor. Check for an out of level condition. Movement can also occur if the bolts holding the Sifter to the
floor or ceiling are loose or if the mounting pads have broken.
•
Mounting Platform Too Weak: Occasionally, platforms are designed and built which are not rigid enough to
support the Sifter or adequately absorb small vibrations that may occur. This is apparent when a Sifter runs
smoothly without a load but causes the platform to shake when loaded. Consult a structural engineer
regarding reinforcement of the platform or consult with Great Western about adding bracing to the Sifter.
•
Bad Pillow-block Bearings: The Sifter uses eight (8) pillow-block bearings. Normally, even if the four
attached to the Sifter frame go bad, little can be detected from the Sifter’s operation. However, if any of the
four bearings attached to the upper and lower dome drive frames wear, to where they have significant play,
the Sifter will shake excessively. Remove these bearings and replace them if excessive play or wear is
detected.
Vibration Troubleshooting
VT
(TBI)
2 of 2
•
Broken Drive Component: If the upper or lower dome drive frames or any of the four bearing frame support
arms have broken, a mechanical punch or vibration will result when operating the Sifter. Due to the precision
to which these Sifters are manufactured, it is not possible to weld the broken components; they must be
replaced. Also verify that the knuckle has not broken loose from the weight bucket. If it has, the entire bucket
assembly should be replaced.
•
Out of Balance: Verify that the lead weights and wooden spacers are in the bucket in the number and
sequence shown by checking the weight chart on the weight buckets. Generally, if the housing, sieves, and
weights in the weight bucket have not changed, then the originally balanced Sifter will remain in balance.
