Title:

An Apparatus and Method for Dry Separation of Materials Based Upon Their Density Difference

Area:

Engineering Sciences, Material Sciences

Focus Area:

Development of Dry Separator

Social Benefits:

Bubbling which is most common in gas fluidized beds can be reduced, Forces balance on the particle changes, as fluidization forces are at an angle, which resulted in a decrease in the minimum fluidization velocity of particles, The difference between minimum fluidization velocity of low-density particles and fluid velocity is enhanced compared to the difference between minimum fluidization velocity of the high-density particle and fluid velocity which results in improved separation, Dead zones are minimized due to inclined fluidization as air traces a larger path reaching long lengths of a separator

Brief Description

Description :

The developed dry separator is used in any field which separates materials/minerals based on their density difference without using any chemicals, water. The technology key technical features are as follows: The angle of Fluidization adjustment from 0-90 degrees resulting in a change in force balance of particles. Dry density separation of materials ranging from 500 kg/m3 - 7000 kg/m3. This range of density separation can be enhanced by enhancing the fluidization which can be done in the fabricated dry separator. The pulsation frequency of air is in between 0-60 Hz
