4.0 MEDIA CLASSIFICATION
Media Classification Process:
(1) Connect unit to an adequate electric supply, and turn on.
(2) After blasting Sponge Media abrasive, collect and pour it into Hopper.
(3) Sponge Media abrasives and small contaminants pass through Top
Screen, while oversized particles exit via Large Particle Downspout.
(4) Spent Sponge Media abrasives and small contaminants pass below
Bottom Screen, and exit through Fine Particle Downspout, while
reusable-sized Sponge Media abrasives exit above Bottom Screen via
Reusable Media Downspout.
IMPORTANT: Proper separation of oversized and undersized particles from
reusable Sponge Media™ abrasive is critical to reducing airborne dust and
minimizing risk of clogging Sponge-Jet Feed Unit™ while blasting.

4.1 TOP SCREEN - LARGE PARTICLE
CLASSIFICATION
Top Screen is a standard #3 mesh screen used to separate unwanted foreign
matter larger than most Sponge Media particles. Items such as nuts, bolts
or rocks are separated and discharged as oversized particles through Large
Particle Downspout.
WARNING:
Oversize particles, if re-introduced back into Working Mix, can cause harm or
damage by (1) becoming a projectile capable of injuring people, (2) harming
work surface, (3) piercing pressurized blast hose, (4) clogging Feed Unit and/
or (5) damaging/jamming the drive mechanism.
4.2 REUSABLE MEDIA
Sponge Media that do not pass through Bottom Screen exit unit via Reusable
Media Downspout. Sponge Media abrasive that exit Reusable Media Down-
spout can be reused in Sponge-Jet Feed Unit.
Working Mix: a blend of blasted Sponge Media passed through Recycler (as
reusable Sponge Media) plus a quantity of new Sponge Media added every 2-3
passes through Recycler. Generally this is 1-2 bags per hour, per nozzle.
4.3 BOTTOM SCREEN - FINE PARTICLE
CLASSIFICATION
Bottom Screen is a number #16 mesh screen used to separate foreign mat-
ter smaller than most Sponge Media particles. Fine particles are separated
from Sponge Media and discharged through Fine Particle Downspout and are
normally considered waste. Fine particles usually include paint chips, broken
down (spent) Sponge Media. These fine particles,
if added to the Working Mix, will increase ambient dust levels at work site.
Important: Dust level tolerance can change from project to project and is
subject to guidance from project management. When hazardous materials
such as lead paint, chromates, radionuclides, cadmium, or PCB’s are present,
there are additional demands for managing dust and waste according to best
practices and applicable local, state and federal regulations.

6.0 NORMAL OPERATION
IMPORTANT: It is essential not to restrict movement of vibrating portion of
unit. It is recommended no rigid connections be added to inlet/outlet of unit.
Rigid connections can reduce eciency of unit and lead to extra fatigue of
sheet metal parts and weldments.
6.1 ADJUSTMENT OF PAN CLAMPS
Pan Clamps have a simple adjustment that allows for dierent thicknesses of
Flat Gaskets.
Adjustment is made by turning Pan Clamp Hook. Under normal operation,
adjustment should not be necessary if all Pan Clamps and gaskets are in their
proper location. Pressure required to close the four (4) Pan Clamps should not
exceed 6.8 kg (15 lb) or each at the end of Handle.
WARNING:
Do not apply excessive force while tightening Pam Clamps. Vibration of unit
can cause overtightened clamps to break.
6.2 FILLING THEN STARTING UNIT
1. Sponge Media is added through Hopper located on top of unit.
2. After connecting unit to an adequate electrical supply, activate by turning
On/O Switch to “ON”. A powerful gyrating vibration will occur.

7.0 ADVANCED OPERATION
IMPORTANT: Before operation, if unit has been disassembled, verify the fol-
lowing has been completed:
- There is no restricted movement of vibrating portion of unit.
- No rigid connections have been added to inlet/outlet of unit. Rigid connec-
tions can reduce eciency of unit and lead to extra fatigue of its sheet metal
parts and weldments.
7.1 AMPLITUDE OF VIBRATION
Adjustment during use of unit should be kept to a minimum. One variable the
operator should be concerned with is amplitude of vibration. Unit has one (1)
Flywheel, which is adjustable to five (5) varying degrees of “o-center”. This
adjustment will modify horizontal amplitude. Located below Flywheel hous-
ing (on flywheel shaft) is an adjustable weight. When the weight is set o cen-
ter from upper flywheel weight, varying amounts of vertical deflection occur.
This deflection is also a function of the RPM from the Flywheel.
7.2 PROCEDURE FOR ADJUSTMENT
OF AMPLITUDE
Adjust Flywheel as follows:
1. Remove Sieve Assembly to expose top bearing housing bracket.
2. In the bracket there will be a ½” “thru-hole”. Rotate Flywheel until the ½”
socket head cap screw comes into view. Amplitude setting numbers will
range from 1 to 3.
3. Remove screw until Flywheel slide weight can be rotated to desired setting
number.
4. Tighten screw securely.
Adjust Kicker Weight as follows:
A second adjustment is available by moving kicker weight. To adjust kicker
weight, remove Side Cover. Kicker weight is located directly above upper cou-
pling flange. One (1) bolt clamps the fan-shaped weight to the shaft.
This weight is set by factory at zero degrees with flywheel weights. To achieve
maximum amplitude, loosen with 5/16” Allen wrench; rotate weight 180 de-
grees and tighten. Settings between 0 degrees and 180 degrees are available.

14 | SPONGE-JET 35E 50E USER MANUAL
ADVANCED OPERATION (CONTINUED)
NOTE: The amplitude setting of the Electric Media Recycler, with the flywheel
shaft running at 3450RPM, should not exceed flywheel setting #3, which is
factory set. Adjustment requires the use of a RPM calibration tool.
WARNING: Failure to use a calibration tool or properly set the RPM rate can
damage the equipment and will void the warranty.
7.3 ALIGNMENT
Prior to shipment, this unit has been adjusted for ecient operation. Under
normal operating conditions, these settings should not need adjustment.
However, shocks can occur during shipment, which may necessitate slight
re-alignment. Ecient operation results when motor and flywheel shaft are
parallel. When this occurs, faces of the flywheel Upper Coupling Flange and
the motor flange are also parallel.
If uneven vibrating or jerking occurs, check that coupling faces are parallel
by measurement. If they are not parallel, adjust by varying length of three
(3) Suspension Rods. To perform this operation, loosening and screw up (or
down), the three (3) pairs of hexagon nuts. Secure base of Suspension Rods
and lower compressed rubber bushings. After adjustment is made, these
nuts must be securely tightened. At the same time, check that the faces of the
flanges are parallel.
7.4 ALIGNMENT OF FLANGES
A minimum clearance of 1 ¼” (32 mm) must be maintained between faces of
the Coupling Flanges. Coupling Flanges must be held parallel to within .010in
(0.254mm). Parallel alignment of flange is performed by adjusting three (3)
lower Suspension Rod nuts. After coupling flanges are proven to be parallel,
installation of flexible rubber coupling may proceed.
NOTE: Flexible Rubber Coupling is 1” (24.5 mm) thick with four (4) 1/8” (3.2
mm) thick bosses.
WARNING: Never run motor with only flexible rubber coupling attached to
motor flange. Failure may result in serious damage and/or injury.
