Separation of particles using a rotating tilted open column with steady flow
[COLOR=#3E3E3E][INDENT][SIZE=3][FONT="]I am working on a new project. The separation of particles using a rotating tilted open column with steady flow of a +/- 50-55% liquids to +/- 40-45% solids mixture.
I found the article below on the internet but did not see a reference to the author. If you know the author or consider yourself an expert in the field, please contact me.
[/FONT][/SIZE][COLOR=#2E2E2E][FONT=NexusSerif][COLOR=#0000ff][I][SIZE=3][FONT="]In the improvement of a rotating tilted liquid column (RTC) method (closed and open-bottom column systems), we have developed a method for rapid selective separation of particulate materials in a continuous or semi-continuous process: a rotating tilted open column with steady flow (RSF) method. The separation power of the RSF method is represented as (a[I]j[/I]/a[I]i[/I])[I]n(RSF)[/I], where a[I]i[/I] and a[I]j[/I] are radii of particles with the same density. The power index n(RSF) will increase with increase of the column rotation ω within the practical range of 1.3 ⩽ Aω/V[I]0[/I] ⩽ 7, where A is the radius of the column and V[I]0[/I] is the free falling velocity of the particle.[/FONT][/SIZE][/I][/COLOR][/FONT][/COLOR]
[COLOR=#2E2E2E][FONT=NexusSerif][COLOR=#0000ff][I][SIZE=3][FONT="]From the relationship between particle loci and distribution of liquid flow speed, we derive an approximate equation to calculate n(RSF) practically and demonstrate the relationship 2 < n(RTC) < n(RSF). Further, n(RSF) takes a maximum value at θ = 0° when ω is fixed, and it sometimes exceeds the upper limit (= 4) of n(RTC) in the RTC method.[/FONT][/SIZE][/I][/COLOR][/FONT][/COLOR][/INDENT][/COLOR]
