FEATURES
The CSI Model WSM-03 Continuous Centrifuge is a screen type centrifuge in which the flow of
the feed material through the centrifuge is automatically controlled to obtain liquid-solid
separation. Figure 1 shows the flow of material through the CSI Model WSM-03 Continuous
Centrifuge. A study of this sketch will enable the operator to more clearly understand the
operation of the unit.
After the feed is introduced through the feed chute, it is immediately accelerated to machine
speed by the cone cap and flites and is directed to the screen surface. Liquid-solid separation
starts immediately upon contact with the screen surface. The flow rate over the screen is
controlled by the speed differential between the cone and the basket and by the flites, which also
agitates or rolls the solids to further assist separation. Solids are discharged at the screen bottom
and fall by gravity into the discharge area of the machine. Solids can be collected by the
operator’s hopper or conveying means directly underneath the machine. Liquids are discharged
through the screen and discharged through the effluent openings.
During the design of the CSI Model WSM-03, an effort was made to improve maintenance
procedures compared to other types of centrifuges. All normal wear parts are easily accessible
from the top of the machine. Belts can be easily changed without removing the gear assembly
and the entire gear assembly can be removed with little effort.
Your CSI Centrifuge is designed for high-speed service with particular care taken to assure its
vibration free operation. Each component making up the rotating assembly is individually
balanced so that all parts are completely interchangeable without disturbing the balance of the
whole assembly.
The function of the gear unit is to provide a differential speed between the cone and basket.
Because the gear assembly is a self-contained unit, it should be replaced as a unit.
Lubrication is provided with an external circulating oil pump. The oil pump and filter are all
connected to the outside of the machine for easy access.
To assure proper lubrication is being provided to the gear unit and bearings, a pressure switch
and flow switch have been provided. By connecting these switches into the main motor control
circuit or to an alarm, one can be sure lubrication is being provided.

CSI SERVICE POLICY
CSI understands the importance of extending to the operator of our equipment the best service
possible. Importance lies in the high value that must be placed on a satisfied customer and the
extra profits that the operator will realize from peak mechanical and process performance. The
latter enables you to stay in business and remain competitive.
We have a service program that is set up to reach the goals outlined above. We have qualified
factory-trained personnel available. These men are trained and qualified both in maintenance and
processing. Their duties are to assist in initial start-up of the equipment, train-operating
personnel, and thereafter make regular routine visits to discuss and consult on operating
problems. The latter presents an opportunity to compare different operations and pass on
operating tips that are usually most helpful. During these visits, the CSI Service Man is able to
ascertain first hand if you are obtaining the best performance possible, and if not, make
corrective recommendations.

INSTALLATION
The CSI Centrifuge is shipped as a completely assembled unit. The machine should be installed
exactly as received.
Location of the centrifuge with respect to its auxiliary servicing equipment should be carefully
studied. Although the centrifuge requires very little space, adequate working space should be
provided around the machine. Wear parts such as the screen, flites and rotor must be attended to
relatively often. This means the water shield, which is approximately 55" in diameter, weighing
approximately 300 pounds, must be stored or placed out of the way for removal of the remaining
parts. To obtain more detail on additional parts removal, refer to the maintenance section.
To assist in routine maintenance, a Monorail should be placed directly above the machine for parts
removal. It is suggested that enough capacity be constructed into the rail to lift the complete gear unit,
which weighs approximately 460 pounds.
A swing away or easily removable feed chute should be used. This will make maintenance much
easier and should be considered when designing the feed chute.
A level foundation should be provided. The machine has been machined level at the factory,
therefore, leveling after installation should not be necessary.
Because the centrifuge is mounted direct to the foundation, rigid connections can be made to the
effluent openings. However, it is desirable to provide an opening in the effluent line so that spot
checks can be made to determine the screen condition. A screen with larger openings than the
machine screen can be inserted into the effluent to check the particle size going through the machine
screen. If large pieces appear on the check screen, the machine screen should be changed.
The 30 HP main drive motor should have the oil pressure switch, flow switch, and oil pump motor
wired into its circuit. By wiring the oil pump motor, flow switch and pressure switch into the main
motor controls; one can be assured that proper lubrication will always be maintained.
Always wire the main motor for clockwise rotation when looking into the main rotation motor shaft
end or as marked on the outside base wall. For proper machine operation, the rotation direction must
be observed.
ALL MACHINES AND CONTROLS SHOULD BE GROUNDED AND WIRED IN
ACCORDANCE WITH NATIONAL ELECTRICAL CODES AND LOCAL CODES AND
ORDINANCES.

As mentioned in the paragraph on the main drive motor wiring, the pressure switch and flow switch
should be wired into the motor control circuit. By properly wiring these switches, one can be assured
of always having proper lubrication.
After complete machine installation, a check of all oil lines should be made. This is a precaution that
should be taken to assure that no damage occurred during shipment or installation.
CSI has available upon request and as an option, field service engineers on hand to direct and assist
with new machine start-ups. This gives the customer an opportunity to get direct operating
instructions from experienced personnel and to get acquainted with the men who can be made
available for inspection calls. Please arrange to notify CSI approximately three weeks before start-up
is anticipated. A fee schedule for technical support and training is available upon request.
Refer to the Installation Diagram, FIGURE II, for mounting dimensions. Keep in mind that adequate
maintenance room must be allowed for as mentioned in the above. Should further details concerning
mounting be required, consult CSI or its field representatives.

OPERATION
Economical and trouble free operation of any process equipment is dependent upon factors such as
maintenance procedures and general overall care of the equipment. To be assured that good
maintenance procedures are being followed, one should understand the general operation of the
equipment. This section contains information that is intended to serve as a process and mechanical
guide for the proper operation of the centrifuge.
In order for the operator to obtain a full understanding of the centrifuge function, a study should be
made of Figure I, where a general flow description is given.
Before any attempt is made to start the CSI Centrifuge for the first time, a quick check should be
made of the following points:
1.) Free Rotation - The motor sheave should be free when turned by hand.
2.) Oil Level - The machine is shipped full of oil; however, it should be checked after machine
installation. Always start the oil pump motor before starting the main drive motor. When
properly wired, the main drive motor will not start before the oil pump motor is started.
3.) Rotation Direction - When looking directly into the main drive motor shaft, it should be
clockwise.
4.) Electrical Connections of Protection Cut Outs - The main drive motor should not start
before the oil pump motor is started. One should be able to hear the pressure switch by
turning the pump motor on and off. Disconnecting the pressure line should cause the pressure
switch to drop out. A flow switch is also wired into the control circuit to assure proper
lubrication of the main drive and oil pimp motor.
5.) Oil - The pressure should read approximately 15-20 psi when the machine is warm. Should
the pressure side drop below 3 psi, the pressure switch will kick out.
6.) Motor Loads - Check the no load motor amperage and compare to the operating amperage.
7.) Observation of Unload Sound –The operator should be familiar with the normal operating
sounds of any equipment.
Always start the machine in an unload condition. If the machine should be started in a loaded
condition, the required load could exceed the motor capacity. To be assured that the machine is left
clear of any material after use, it should be allowed to run approximately ten minutes after the
feed has been cut off.
The operator should always be aware of the normal oil pressure, motor amperage, effluent solids
content and vibration level. By watching the above characteristics one can be fairly certain that the
machine is operating properly. Here is a table giving the above symptoms with their cause and cure:
