• Low Polymer Consumption Patented feed zone design reduces flocculant usage by 15 to 20 percent compared to conventional centrifuges

Table 1: Two Phase vs Three Phase Decanter Centrifuge Comparison

Type	Separation Components	Typical Applications
Two Phase Decanter Centrifuge	Solid + Liquid	Sludge dewatering, wastewater treatment, slurry thickening
Three Phase Decanter Centrifuge	Solid + Light Liquid + Heavy Liquid	Oil water solid separation, edible oil refining, chemical extraction

How does a decanter centrifuge work?

Working Principle Step by Step

Step 1 Feed Entry
Slurry enters the machine through a stationary feed tube into the mixing zone where flocculant can be added for optimal solid liquid separation.

Step 2 High Speed Rotation
The bowl rotates at high speed typically 2000 to 4000 RPM generating strong centrifugal force that pushes heavier solids outward against the bowl wall.

Step 3 Solids Settlement
Solid particles settle and compact against the bowl inner wall while lighter liquid forms an inner layer closer to the rotation axis.

Step 4 Scroll Conveying
The scroll rotates at a slightly different speed differential speed pushing settled solids toward the conical discharge end.

Step 5 Dry Solids Discharge
Dewatered solid cake discharges continuously through solids outlet ports at the conical end of the bowl.

Step 6 Liquid Overflow
Separated clarified liquid flows over adjustable weir plates and discharges through the liquid outlet at the opposite end.

Step 7 Three Phase Separation Optional
For three phase configuration liquid liquid separation occurs simultaneously with heavier liquid water discharging near the solids outlet and lighter liquid oil discharging at the opposite end.
