2.0 INTRODUCTION
This unit is a series of vibratory sieves powered by an electric motor. The mo-
tor connects to a variable speed pulley, and is mounted to a motor mount that
allows the motor to be adjusted by a crank for various RPM changes.
Please study this manual carefully and keep it handy for reference.

INSTALLATION AND STARTUP (CONTINUED)
1) Each unit should be installed on a substantial foundation around the entire
bottom of the unit’s base ring or mounted on casters. After following installa-
tion procedures and unit has been started - if there appears to be secondary
vibrations transmitted to the foundation or to the separator base, the struc-
ture must be reinforced. (With further questions contact Sponge-Jet, Inc.)
Figure 1
2) Make certain unit is level and in a position for easy access to motor and
lubrication points. Refer to maintenance section for proper greasing and
greasing locations.
3) End User must address the hazard of reaching the eccentric weight mech-
anism when the separator is mounted on an elevation as to which it can be
reached from the underside. Provide a plate or screen to prevent this from
happening.

FEEDING AND DISCHARGING CONNECTIONS
Feed material... Sponge Media™ must be fed in the center of screening sur-
face. This is one of key factor in utilizing the unit to its full potential. Failure to
do so will result in excessive wear to a particular section of the screen which
will result in premature screen failure. Failure to feed Sponge Media in center
of screening surface will result in poor eciency and reduce production.
Depth of feed material... If Sponge Media is being fed to the unit at too fast a
rate, some is apt to “ride over”. The result can be poor eciency. To make most
ecient use of vibrating screen, limit feed rate to where the greatest amount
of material can be placed in a position of direct contact with screen (at which
point there is the most concentrated vibratory impulse). Further, a heavy feed
can pound near-size particles into screen, making it dicult for vibration
to dislodge them. Eventually, overloading unit this will result in plugging of
screen openings and drastically reduce eciency.
Discharge chute or hopper should be located to receive every particle from the
unit. In general, feeding and discharge connections should have minimum of
2” (51 mm) clearance to frame of unit to prevent any contact.
BASIC FEED CRITERIA:
1. Material is fed to center of screen at a continuous rate.
2. On no account should a column of material be allowed to form, or material
be allowed to drop from any height greater than 12” (305 mm) onto screen.
3. Stop feed and allow material to run through before turning it o. This helps
to prevent strain on unit.

SCREEN INSTALLATION
Screen installation is one of the most important aspects of any screening
equipment. Incorrect screen installation causes not only poor separation but
can destroy a screen.
BASIC SCREEN CHANGING STEPS
1. Before starting any screen changing steps be sure to Lockout/Tagout the
machine.
2. Loosen and remove the outer “V” clamp ring using a 3/8-inch drive ratchet
with a 6-point deep well socket.
3. Take this time to wipe o any excess material or debris left on the screen
before removing. Then remove the screen and set it o to the side.
4. To secure the screen properly take the time to thoroughly clean both the
spacing frame flanges.
5. Replace the spacing frame. Make sure the screen and frame are centered
on the frame below.
6. Install the “V” clamp ring making sure the nut of the clamp ring bolt is on
your right-hand side. If your clamp ring has a quick release over the center
latch secure before tightening.
7. The Clamp ring should be tapped moderately with a rubber mallet during
tensioning to insure it will seat properly.
8. Tighten the two clamp ring bolts equally to ensure even tensioning. (Pass
the tools around the separator so nothing accidentally falls onto the new
screen.)

5.0 MAINTENANCE
AND REPAIR
5.1 WEIGHT ADJUSTMENTS
The vibratory motion of unit is controlled by addition or subtraction of weights
to balance cage pins. The top and bottom balance cages are round plates
(much like flywheels) with pins.
Top balance cage is known as horizontal cage. Weights added to this produce
horizontal or flat eect of screen. Thus, if you are screening heavy material,
more weights would be added to top cage to create inertia necessary to pro-
cess Sponge Media material. Good screening performance cannot be realized
until sucient horizontal motion is attained first.
Bottom balance cage is known as vertical cage. Weights added to this cage
impose a vertical lift on screen which, in combination with horizontal motion,
moves material in a fashion suitable for good particle separation and dis-
charge.
Although weights on this unit have been preset at the factory, this is often just
a starting point -site fine tuning may be necessary.
Following are four weight arrangements and patterns they are most likely to
produce. These diagrams are general aids and should not be depended on as
precise adjustments for your application.
Adding excessive weight does not promote faster or better screening. Too
many poorly adjusted weights will only shorten unit’s life. Acceptable screen-
ing is never accomplished by brute force, but by proper adjustment to unit.
Caution:
1. Before starting weight adjustment be sure to Lockout/Tagout the machine
each time there is adjustments that need to be made.
2. Feed limited amounts of material to the screen to check the flow pattern
and pinpoint what pattern is being illustrated in figures 16 through 19.

16 | SPONGE-JET 70P 70E USER MANUAL
If material is moving around screen surface similar to flow pattern in figure
9, and it is preferred to have unit to perform as shown in figure 8. Shut down.
(Lockout/Tagout unit, be sure that all moving parts have stopped moving!) Re-
move weight from bottom balance cage and index clockwise one or two pins.
(Example: If weight is located on pins 5 and 6, place on pins 4 and 5) When all
hands are clear, start unit and check the flow pattern.
If material is not being retained on screen surface long enough, similar to flow
pattern on figure 7. Shut down. (Lockout/Tagout the machine, be sure all mov-
ing parts have stopped moving!) Remove weight from bottom balance cage
and index counterclockwise one or two pins. (Example: If weight is located on
pins 2 and 3, place weight on pins 4 and 5) When all hands are clear start the
separator and check flow pattern.
3. If you have tried various tilt convey settings described above and cannot
achieve acceptable screening, please contact Sponge-Jet, Inc. for more adjust-
ment assistance.
4. Recommended weight settings for figure 6 are Top mobile weight on pins
numbered 1 and 2, Top fixed weight on number 1 and 2, and Bottom mobile
weight on pins numbered 2 and 3.
5. Recommended weight settings for figure 7 are Top mobile weight on pins
numbered 1 and 2, Top fixed weight on number 1 and 2, and Bottom mobile
weight on pins numbered 4 and 5.

weight on pins numbered 7 and 8.

5.3 RPM ADJUSTMENT:
Another dimension of adjustment incorporated in this unit is variable speed
RPM adjustment. This unit can be adjusted from 950 RPM to 1450 RPM. This
unit is set at 1250 RPM from the factory.
The lower RPM range produces greater amplitude or stroke length but lower
frequency and a moderate rate of material flow. Higher RPM reduces am-
plitude but increases frequency and the material’s rate of travel across the
screen.
ADJUSTMENT STEPS:
1. Before starting any RPM Adjustment steps Lockout/Tagout the machine.
2. Loosen RPM control lock (Motor Lock) at top of motor mount next to vari-
able speed pulley (figure 12).
3. To adjust the RPM the unit must be running - so use extreme caution.
4. With the crank supplied with the unit, attach it to the adjustment screw.
(figure 12).
5. To increase RPM, rotate crank counterclockwise (inward). To decrease RPM,
rotate crank clockwise (outward). One turn of crank is approximately equal to
a change of 35 RPM.
Note: RPM stops on motor mount that are factory preset. These motor stops
must not be changed.
6. When desired RPM is reached, Lockout/Tagout the unit.
7. Tighten RPM control lock (Motor Lock).
CAUTION: RPM control lock must be tight at all times when motor is running
during full production. If unit is operating with a loose RPM control lock this
may aect warranty.
