Static Mixers | samhwa

Samhwa static mixers provide continuous in-line mixing fluids, gases, or powders using no moving components. Our S-type mixers incorporate alternating helical elements, each set 90˚ to its adjacent elements, to provide through blending over a short length for a wide variety of materials.
Samhwa mixers are custom designed for each application. The number of mixing elements is determined by the specific requirements of the application. Mixers can be jacketed or electrically heated and supplied with fixed or removable element strings. Also, edge seal type is provided for special applications. Sizes range from 2 mm to more than 2 meters in diameter.

Flow Division
As the product stream passes over each mixer element, it is divided into two equal halves. With each succeeding element, the number of divisions grows exponentially equal to 2ⁿ, where n is the number of mixer elements.
For example, the cross-section photos at right of an 8-element mixer represent 2⁸or 256 divisions. Accordingly, 20 element mixer will produce over a million divisions of product.

Rotational Circulatio
The first helical element rotates the flow in one direction, then the direction is reversed at the next element. This action creates a further mixing effect, promoting product uniformity

Radial Mixing
The flow is forced to be inverted completely so that particles entering at the center of the stream are continuously mover to the outer wall and back again.
