WORKING PRINCIPLES OF DYNAMIC SEPARATOR

Slide 2:

A Dynamic Separator is an industrial machinery which segregates materials by a combination of size, shape, and density. It is designed to separate primarily sized fraction from small ones. The machinery supplied by Dynamic Separators suppliers are commonly employed in industrial processes where a large volume of mixed materials with differing physical characteristics need to be sorted quickly and efficiently. The most significant feature of the dynamic separator is the ability to regulate the grinding fineness utilizing rotor rotation frequency and stator blades setting angle.

MECHANISMS & WORKING

Slide 4:

The material is fed at the top of the separator.                          To enhance the dispersion of the material, 2 or more feed chutes are present. The material is then dispersed in the circulating air via the distribution plate.                   The feed forms a thin cylindrical curtain of material in the classifying zone. After which, the air stream is generated by an external fan.                             According to the type of circuit, it is possible to have 100% of fresh air, or recirculate a part of the air or have 100% of the air recirculated.

Slide 5:

There are a number of air inlet which is further segregated into primary, secondary and tertiary depending on the design. Through these inlets, the airflow then leaves the guide vanes almost tangentially to the outside of the cage.                Then, the material falls in the separation zone between the guide vanes (or louvres ) and the rotating cage.          The particles are driven by three forces: The centrifugal force due to the dispersing plate                 * The centrifugal force because of the dispersing plate                                * The drag force because of the airflow                                    * The gravity due to the mass of the particle

Slide 6:

The drag force tries to pull the material into the rotating cage.                    The centrifugal force tries to push the material toward the guide vanes.                     And, it is the balance of these forces that induce a regular cut size of the separator.            This balance remains steady as the material in the classifying zone always has the same radius of rotation, then the centrifugal force is the same in all areas.   

Slide 7:

On the other hand, the air and material are uniformly distributed, and the air velocity (then, drag force) remains equal. The coarse material doesn't enter in the rotating cage and goes out by gravity up to the bottom device. The end product, i.e., fine material enters in the cage and exits with the airflow via either the upper or the lower part of the separator.
