Steel Lined PTFE Agitator

Steel lined PTFE agitator forces forced convection and uniform mixing of liquid and gas media. The type, size and rotating speed affect power distribution between overall flow and turbulent pulsation. Proper selection reduces daily management troubles and safety hazards, serving as a priority for chemical anti-corrosion equipment procurement.

Agitator selection depends on material viscosity and other properties. Different structures apply to diverse working conditions. Main types are introduced as follows:

1.Turbine TypeConsists of 2 to 4 straight or curved blades mounted on a horizontal disc. The outer diameter, width and height ratio is generally 20:5:4, with peripheral speed 3~8m/s. It generates intense radial turbulent flow, suitable for gas dispersion, immiscible liquid mixing and liquid-liquid reaction. Applicable liquid viscosity: below 25Pa·s.

2.Propeller TypeComposed of 2 to 3 propeller blades with high rotating speed and peripheral speed 5~15m/s. It produces strong axial flow and large circulation volume. Ideal for low-viscosity liquid, emulsion and suspension with solid particle content under 10%. Horizontal or inclined installation enhances turbulence and avoids liquid surface depression.

3.Paddle TypeDivided into flat paddle and inclined paddle styles. Flat paddle has two straight blades with diameter-height ratio 4~10 and peripheral speed 1.5~3m/s, delivering mild radial flow. Inclined blades tilted at 45° or 60° create axial flow. Simple structure fits low-viscosity liquid mixing, solid dissolution and suspension.

4.Anchor TypeBlade outline fits the tank inner wall with tiny clearance, effectively scraping viscous deposits and bottom sediments to maintain heat transfer efficiency. Peripheral speed ranges 0.5~1.5m/s. Applicable to Newtonian and pseudoplastic fluid with viscosity up to 200Pa·s.

5.Ribbon TypeOuter diameter equals pitch, specially designed for high-viscosity fluid of 200~500Pa·s. Normally operates under laminar flow condition.
