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.
