Key Features
The rotating part of these decanter tricanter centrifuges is
mounted on a compact, in-line frame with main bearings at both
ends. Vibration dampers are placed under the frame. The rotating
part is enclosed in a casing with a cover and a bottom section with
integrated outlets for both solids and the liquid being removed.
Quality Assurance & Certifications

Working Principle - 2-Phase Separation
The feed suspension is introduced through an inlet pipe into the
feed zone of the conveyor where it is accelerated and directed into
the interior of the bowl. The settled solids are conveyed axially
towards the small end of the bowl by means of the screw conveyor,
which rotates at a slightly different speed than the bowl. On the
way to the discharge ports the solids are lifted out of the pond up
along the dry beach. The solids are finally discharged from the
bowl through the discharge ports into the collecting chamber of the
casing that surrounds the bowl. From there the solids are removed
by gravity through the outlet funnel. The liquid phase forming a
hollow cylinder due to the centrifugal force, and flows towards the
large end of the bowl. There the liquid overflows adjustable plate
dams into the centrate chamber of the casing and is discharged by
gravity.

Working Principle - 3-Phase Separation
The light liquid phase is discharged into the casing through radial
holes in the large end hub. The heavy liquid phase is discharged
through axial holes in the large end hub. The liquid radius for the
light liquid phase is smaller than the radius for the heavy liquid
phase. The liquid level is controlled by plate dams. In order to
prevent the light liquid phase from leaving the bowl through the
heavy liquid phase outlet, a separating plate is placed on the
inside of the large end hub. The heavy liquid phase has to pass
under the separating plate before being discharged into the casing.
The liquid radius for the heavy liquid phase is controlled by plate
dams. The solids are discharged in the normal way.

Construction Materials
The bowl, conveyor, inlet tube, outlets, cover and other parts in
direct contact with the process media are all made of stainless
steel. The discharge ports, conveyor flights and feed zone are
protected with materials that are highly resistant to erosion. The
frame is made of mild steel with an epoxy enamel finish.
Wear Protection Options
Huading Separator supplies a wide range of wear protection for
decanter centrifuges to meet the requirements of various
applications:
- Welded hard facing or spray coating
- Ceramic
- Tungsten carbide tiles
- Chilled hard metal portcastings
- Plastic liners
Drive System Options
One Motor Drive
This is a very simple design that is cost-effective to purchase and
operate. One motor drive systems are used when solids volume is
constant, solids are easy to convey, and requirements for residual
water content are not stringent. The input shaft of the drive is
set in motion by the main motor via a second belt drive, generating
differential speed as a function of bowl speed and gear
transmission.
Two Motor Drive
This system enables cost-effective regulation of differential speed
under good operating conditions with wide regulating ranges. The
secondary motor sets the input shaft of the gear in motion and
generates differential speed as a function of bowl speed and gear
transmission. Used when solid volumes fluctuate significantly,
solids are conveyed under difficult conditions, and stringent
requirements apply to residual water content.
Hydro Drive
Similar to two motor drive but with a rotating hydromotor installed
instead of mechanical gear, supplied with hydraulic regulation by a
pump unit. The differential speed is proportionate to the conveyed
quantity of oil, allowing for automatic regulation.
