CBB Decanter Centrifuges have different configurations and possibility of choice for transmission type of bowl and screw rotation.
Available transmission type:
- Variable speed transmission with electric motor and closed circuit hydraulic pump/motor;
- Variable speed transmission;
- Variable speed transmission with double electric motor;
- Fixed speed transmission;

Transmission of bowl and screw rotation occurs through belt transmission and it is
induced from an electric and a hydraulic motor, controlled through a closed circuit from
a hydraulic pump; in this case machine works with variable speed, that is in order to
change differential speed between screw and bowl is sufficient change hydraulic motor
speed.
Moreover, it is possible to change speed of bowl changing speed of
electric motor.

Scroll Motor
Transmission of bowl and screw rotation occurs through belt transmission and
it is induced by a double electric motor; in this case the machine works at
variable speed, that is in order to change differential speed between screw
and bowl it is sufficient changing the speed of electric motor of the screw.
Moreover, it is possible to change bowl speed changing speed of
electric motor of bowl.
VARIABLE SPEED TRANSMISSION
with double hydraulic
motor
Transmission of bowl and screw rotation occurs through belt transmission and it is induced by two hydraulic motors, controlled by a closed circuit by two hydraulic pumps; in this case machine works at variable speed, that is in order to change differential speed between screw and bowl it is sufficient change screw hydraulic motor speed. Moreover, it is possible to change bowl speed changing speed of bowl hydraulic motor.

Belt
Transmission of bowl and screw rotation
occurs through belt transmission and it
is induced by a single electric motor;
in this case machine works at fixed
speed, that is in order to change
differential speed between screw and
bowl it is necessary to change pulleys
and belts.
Moreover, it is
possible to change bowl speed changing
electric motor speed.
