Anchor Agitators

Anchor Agitators: Anchor Agitators consists of a shaft and an anchored propeller that can be mounted centrally or at an angle. It is mainly used in reactors.

Anchor Agitators

Paddle Agitators: Paddle Agitators is one of the most important types of agitators whose blades reach the tank wall. A Paddle Agitators is used where a uniform laminar fluid is required. It implements heavy-duty mixing and proves to be an excellent device for low speed. Its simple structure makes the machine easy to manage.

Radial Propeller Agitators: The radial agitator consists of a propeller similar to a marine propeller. They consist of two to four blades that move in a screw-like manner, pushing the material parallel to the shaft for agitation.

Propeller Agitators: It is an axial flow high performance mixer consisting of three blades mounted on the main shaft. They are ideal for mixing low viscosity and medium viscosity fluids and improving uniformity. Propeller agitators are popular for simple mixing jobs.

Turbine Agitators: Turbine Agitators are widely used to perform all types of mixing operations and to handle fluid and liquid or gas reactions of various viscosity. Its ability to produce high radial flow facilitates the dispersion operation.

Helical Agitators: These agitators have blades with a twisting mechanism, just like the threads of a screw. The curve results in strenuous movement of the fluid to be agitated. Spiral mixers are best suited for mixing viscous liquids.
