2GENERAL INSTRUCTIONS

“SP SERIES” USER MANUAL
Page 8 / 34
2.1 Working wit slurry
WARNING !
Slurry can emit lammable and nauseus gase
s
. Always ensure that
there is proper ventilation in the operation area.
2.2 Proper Usage
EYS screw press separator is designed to separate solid and liquid phases o iber-rich waste materials.
The waste should be ree o sand, as well as other oreign objects such as metal, glass, wood, etc. that
have the potential o damaging the internal parts o the separator.
3OPERATION PRINCIPLE
Slurry can be ed into the EYS Separator either by a pump or gravimetrically through a hopper at the
inlet. The auger inside the separator moves the slurry orward rom the inlet section towards the solids
discharge outlet. During this travel o the slurry, the cylindrical screen around the auger continously
dewaters the liquid raction o the slurry and channels it out through the liquid discharge outlet.
Meanwhile the dewatered solids orm into a irm plug as they get closer to the discharge area. At the
solids discharge outlet, there are two hinged doors that apply constant pressure to the solid plug by
means o counterweights attached to the arms that regulate the angle o these doors. As the auger
urthers the solid plug orward, the plug overcomes the backpressure applied by the discharge doors
and exits the machine rom the discharge outlet.
1. Slurry inlet
2. Auger
3. Screen
4. Solid plug
5. Separated solids discharge
6. Separated liquid discharge
Operational e iciency o the separator (throughput and dryness o solids) is greatly a ected by the
slurry consistency. There ore per ormance results may vary depending on what kind o slurry is being
dewatered. Following principles should be kept in mind when optimizing per ormance.
•Separation e iciency is typically increased when a larger screen slot-size is used. This in turn
will result in more solid particles to escape into the separated liquid phase.
•Smaller screen slot-size typically results in less solids percentage in the separated liquid phase.
However throuhput will be lower with smaller screen slot-sizes.
•Moisture content o the separated solids is typically reduced with increased back-pressure at
the discharge doors.

4.2 Handling
The machine must be handled and li ted with a sa e and proper method as required by the speci ic
circumstances o the installation location. A suitable crane and/or orkli t must be utilized. Please
re er to the above igure or proper li ting arrangements by orkli t or crane.
WARNING !
A properly chosen orkli t can be used or trans erring and/or li ting o the
separator to short distances or heights. Use the speci ically designed orkli t
openings on the legs o the separator. Make sure that the orks o the orkli t
are ully through these openings on both legs. A crane should be employed
when li ting the separator to higher locations (such as while installing on an
elevated plat orm). When li ting with a crane, use two slings o 3m length and
1ton li ting capacity each, together with proper shackles. Apply the slings as
shown in the above igure. Never li t with chain or steel cable. These li ting
procedures must be ollowed not only or initial installation but or subsequent
li tings also, whenever necessary.

4.4 Set-up and Installation
ATTENTION !
Separato
r
should be installed at a reasonable height to allow separated solids
to accumulate easily underneath. Otherwise the separator may become buried
under accumulated solids.
The separated liquid raction will be drained to a separate lagoon (other than
the slurry pit where the separator is being ed rom) gravimetrically. There ore
this lagoon should be planned close to the separation system in order to allow
or easy drainage o the liquid.
Follow the below steps or setting up the separator:

“SP SERIES” USER MANUAL
Page 11 / 34
•Mount the F-Pipe to the inlet pipe o the separator.
•Mount the pump outlet pipe to the 6” upper inlet o the F-Pipe using the quick coupling
connectors.
•Mount a 6” over- low pipe to the lower branch o the F-Pipe using the quick coupling connectors.
This over low line will go directly back to the slurry pit where the pump is.
•Connect the 1,5” air-vent pipe to the over- low line. This line will prevent a possible vaccum e ect
on the over- low line. This air-vent pipe should extend at least 1m above the upper branch o the
F-Pipe (pump line). Make sure that the valve on the air-vent pipe is ree and open.
•Mount a 6” pipe to the liquid discharge outlet o the separator. This pipe will extend to the
separated liquid lagoon. The layout o this pipe should not cause dips along the path, which would
prevent the liquid to drain completely and may cause reeze-ups in the pipe.
•All electric work and connections must be carried out by a quali ied electrician.
ATTENTION!
Over low and separated liquid drainage lines must extend in a linear ashion to allow
easy low o the slurry. Over low line must not be submerged into the slurry pit,
otherwise it might creaate siphoning e ect and divert all slurry low rom the pump
back into the same pit through the over low line.
ATTENTION !
I the pump eeding the separator is not an EYS pump, then a suitable pump must be
used to supply the minimum low rates as per the below table. Otherwise the

“SP SERIES” USER MANUAL
Page 12 / 34
separation e iciency will be compromised. Pipe diameters should not be lower than
4” in order to minimize headloss.

5PRE-STARTUP CHECKS
•Check the oil level in the gearbox, add the appropriate amount i necessary. Make sure the oil cap
is in place on the gearbox.
•Check that all piping connections are securely in place and ree o any obstacles.
•Adjust the motor protection relay to the recommended value ( actory settings or EYS supplied
control panels are: 4,4A or 2.2kW motor, 11A or 5.5kW motor, 22A or 11kW motor). The auger
o the separator turns counter-clockwise during separation. However with each start-up, the auger
irst turns in clockwise direction (backwards) or 5 seconds in order to releave any excess pressure
on the gearbox due to potentially stuck solid plug inside the machine rom the previous run.
•Remove t e counterweig ts from t e arms to minimize t e counter pressure.
ATTENTION !
Make sure that the slurry pit where the separator is being ed rom is ree o oreign
ojects such as sand/metal/wood pieces that can harm the machine. The slurry pit is
an essential part o your separation system. Such oreign objects can cause
signi icant damage to auger and the screen o the separator, and abrasive materials
such as sand would wear out these two parts very quickly also.
6START-UP
ATTENTION !
It is essential to mix the slurry in the slurry pit thoroughl
y prior to starting the
separator. Lack o proper agitation in the slurry is one o the main causes o low
separation e iciency. Agitation needs to be done prior to start o pumping so that
homogenous material is pumped to the separator.
6.1 Counter-pressure on disc arge doors
The consistency and dryness o the solid plug is adjusted by the positioning o the counter-weights on
the separator arms. Counter-pressure is increased as the weights are moved outwards towards the
open end o the arms.

“SP SERIES” USER MANUAL
Page 13 / 34
ATTENTION !
W
ith each adjustment o the counter
-
pressure, the results will change a ter a minute
or two. T erefore please wait for a couple of minutes after eac adjustment to
observe t e c ange in solids output.
6.2 Establis ing t e solid plug
The solid plug will orm soon a ter the separation system is started. First run-and-stop the pump or a
couple o seconds. Then wait until no slurry remains in the pipes, and repeat the procedure again. A ter
3-5 repeats, the plug will have established and solids will start coming out o the discharge end.
An alternative practice is to irst open the discharge doors care ully and manually ill the space behind
the doors with straw or newspaper as a temporary plug. Then the separator and the pump can be
started up in sequence. The plug will orm shortly a ter start up.
6.3 Plug adjustment
If the plug is too dry,
Push the counterweights orward or remove
some o the counterweights.
I the plug has dried up inside the separator
or a long time, it may stall the separator.
Always arrange the counterweights
symettrically on both arms o the separator.
If the plug is too wet,
Push the counterweights backward to apply
higher counter-pressure on the discharge
doors. I not enough, add on more
counterweight on each arm.
I the plug gets too loose, the plug may
breakdown and when that happens, liquid
slurry would shoot out rom the solids
discharge. In that event stop the system and
re-start ollowing the start-up procedures.
Making these adjustments will be necessary to reach optimum separation e iciency with a given
slurry consistency. Adjustments may need to be ine-tuned when the slurry consistency changes
signi icantly due to heavy rain, etc.

“SP SERIES” USER MANUAL
Page 14 / 34
6.4 Ot er points of consideration
Over low line back to the slurry pit must allow ree low o slurry within at all times.
Make sure that the over low line is ree o any obstacles and is not clogged and/or rozen
!
In
regular operation, over low line should be about 1/3 illed with slurry.
Excessive pump thoughput into the separator may lower separation e iciency.
I the pump chosen or the separation system delivers too high a low, the slurry inlet into the
separator should be regulated with a valve on the inlet pipe.
Open end o the over low pipe must not be submerged into slurry in the slurry pit; as this situation
would create a siphoning e ect and all the slurry being pumped through the separator inlet pipe would
then low back into the slurry pit, preventing the slurry rom lowing into the separator.
Over low and liquid slurry drainage lines should not be exposed to conditions that might change their
diameters (such as a vehicle driving over the line, other weights being applied on them, etc.). This
would increase the pressure inside the pipe and may cause the plug to shoot out rom the separator.
In installations where two (or more) separators are installed side by side, one larger capacity pump can
be used instead o individual small pumps or each separator. In those instances, a collector bu er
tank can be arranged above the separators and a single pump can eed this collector, rom which the
individual separators would be ed. A level control sensor would be use ul in the bu er collector.
Slurry inlet pipe o the separator should not be smaller than 4” (Ø100mm). The inlet pipe should
maintain a constant diameter throughout its length. I these conditions can not be maintained, then
use o a bu err tank above the separator and eeding the separtor rom this tank would be
recommended.
Make sure t e slurry is fully mixed prior to separation. This will prevent rom loss o solids plug
unexpectedly due to very thin slurry input, or stalling o the separator motor due to very thick slurry
input. I the slurry pit very small (e.g., smaller than 100m3), then avoid over-agitation as this may
change the iber structure o the slurry and make the slurry less separable.
The separator should be installed as close to the slurry pit as possible, in order to maintain the optimum
piping layout and minimize rictional losses inside the pipes. Layout o the pipes become particularly
important in situations where the horizontal distance between the separator and the pit is more than
10m. Make sure that the slurry pump line and the over low line extend rom the separator to the slurry
pit always with a downward inclination.
The separated liquid discharge o the separator is 4” (Ø100mm). Sthe liquid drainage line rom the
separator to the separateed liquid lagoon should be a minimum o 4” (Ø100mm). In order to avoid
spihoning e ect on this line, or to prevent reezing o slurry inside the pipe, or to avoid blockage as a

“SP SERIES” USER MANUAL
Page 15 / 34
result o solids settlement inside the pipe, make sure that the line extends rom the separator to the
liquid lagoon with a vertical inclination throughout its length.
In extremely cold climates, the pipelines can be wrapped with thermal insulation materials to prevent
reezing o the slurry. In any event, application o electric heaters around the pipes must be avoided
as these may pose a ire hazard in the vicinity o insulation materials.
Slurry pit is an integral part o your separation system, and it is essential that this pit is kept ree o
oreign objects that might disrupt the slurry low through the pipes and/or damage the separator
parts (such as metal parts / wires, plastic parts, wood pieces, sand, large pieces o cloth, plastic
bags, etc.). Mechanical and electrical damages that might occur as a result o such materials inside
the slurry are customer’s responsibility.
Solids discharge o EYS separators are designed with a gear mechanism that maximizes precision o
counter-pressure adjustment. Even though these gears do not move much during operation, hands
must be kept ree o these areas at all times when the separtor is running. Make sure that the
protective cover is kept on at all times other than when servicing the machine. Loose out its, sleeves
and gloves must be kept away rom these gears with utmost attention. When servicing the machine,
utmost care must be taken when the protective cover is o ; hands must be clear o the gears at all
times.

“SP SERIES” USER MANUAL
Page 16 / 34
There is a “gearbox separation lange”
between the body o the separator and te
gearbox. This lange houses a combination o
seals that prevent slurry rom running into
the gearbox. Should both seals ail inside this
lange, the slurry still doesn’t leak into the
gearbox but leaks down rom an opening on
the underside o the lange. Operator should
visually check or any leaks in this area
periodically. I a leak is seen, the seals inside
the separation lange need to be replaced.
Call your dealer or help with these
replacements.
There are cutter screws on each side o the
separator at the slurry inlet area. These
screws are placed to catch long ibers and
otherwise oreign objects be ore they enter
the screen area and blind the screen. These
cutter screws are adjusted and ine-tuned at
the actory prior to shipping. Do not alter the
settings o these screws unless there is a
speci ic need or it.

10 CHECKING THE SCREEN AND SCREEN GUIDE-RAILS
Screen(s) inside the separator and the guide-rails that hold the screen in place will wear out over time.
It is recommended to check these parts or potential wear every 1.000hrs o operation (roughly once
every 5-6 months or 6hr/day operation).
During these checks, irst the screen should be removed rom the machine and cleaned (pre erably
with a pressure washer). Then visually check or any damages and visible wear on the parts. Also check
that the te lon inserts inside the guide-rails have a lat and continuous contact sur ace with the screen
as well as the bottom o the guide-rail itsel . Worn out te lon inserts can cause subsequent damage to
the screen. I necessary, replace these te lon inserts each time you replace the screen.
See section 12 or details on acceptable levels o wear or these parts and how to control them.
Disassembly and assembly o the screen is explained in section 13.
Screen guide rails are astened to the separator with 3 sets o screws each. These screws must not be
tampered with unless there is a speci ic need or it. These screws have been adjusted to the optimum
torque at the actory and typically would not need re-adjusting until the guide-rails and/or the te lon
inserts inside them are replaced. Please consult with your EYS dealer or details on how to make these
adjustments a ter a replacement.
