DRYCAKE: DECANTER CENTRIFUGES
2 and 3 Phase Solid-Liquid Separation
for Industrial and Municipal Applications
u p t o 1 5 0 m3 / h p er C ent rifu g e
DRYCAKE offers a complete range of
mobile and stationary best in class
decanter centrifuge system solutions for
separating 1 or 2 liquid phases from a solid
phase.
Our centrifuges are designed for high
performance and reliable operation under the
most strenuous of conditions.
Innovations such as the sectional
split-case covers, independently
driven solids scraper, zero-footprint
hydraulic back drive, and the high
speed DPC processor, allow us to
offer consistent high performance
while reducing maintenance time and
efforts.
Sectional Split Case:
3 sections open individually allowing easy
access to the solids & liquid discharge
chambers for ease of maintenance.
DRYCAKE Decanter centrifuges
are used regularly in industrial and
municipal applications to recycle
process water, reduce the charge to
the downstream treatment system
and to reduce the landfill disposal
volume.

DECANTER CENTRIFUGES
WEIR LIQUID LEVEL PLATE
DISCHARGE BUSHINGS
A most practical and effective method of
adjusting the liquid level for process
optimization are the DRYCAKE weir
discs. The discs are easily accessible
due to the sectional covers, and the
settings are adjusted by turning the
discs clockwise to the desired set point.
Located at the solids outlet, our
ceramic bushings are rotatable
for prolonged life and easy to
access via the sectional
cover.
SOLIDS DISCHARGE SCRAPER
The scraper prevents build up and
clogging of solids in the solids discharge
chamber, no matter how sticky the
application. The scraper is low rpm,
fully-geared and independently driven.
DECANTER PROCESS CONTROL
The DPC is our proprietary PLC written in assembly
language for a “runtime system” faster than any
commercially available PLC.
Our DPC is fully compatible with all modern SCADA
communication protocols.(standard Modbus RS485)

Torque control is essential to optimal performance.
In centrifuge operation, torque expresses the pressure
applied to squeeze the liquid phase out of the solid phase.
2
4
Too much torque and the liquid will come rushing out the
solids discharge, not enough and you won’t get a dry cake.
6
Hydraulic back drives are preferred over electric backdrives
because they offer better torque control and a flat
performance curve.

CAKE AND MATERIAL HANDLING SYSTEMS
DRYCAKE offers material handling
systems and equipment for a
number of municipal and industrial
applications.
EQUIPMENT:
• Shaftless Conveyors
• Belt Conveyors
• Slewing conveyors
• Horizontal bi-directional
distribution conveyors
• Vertical conveyors
• Live bottoms
• Cake Pumps
• Silos
SHAFTLESS SCREW SYSTEMS
APPLICATIONS:
•
•
•
•
•
•
•
Wastewater treatment plants
Solid waste facilities
Waste to energy facilities
Coal terminals
Bulk materials plants
Aggregrates
Mining
Shafltess screw conveyors are commonly used for dewatered cake discharge. The cake is then
discharged directly into another conveyor, a discharge bin,
distribution or slewing conveyor.
CAKE PUMPS
Our cake pumps are a good
alternative to our conveying
systems, when dealing with large
volumes in small space and
distance.
