How to Calculate and Solve for Force Settling Ratio | Fine Particles | Mineral Processing

Last Updated on May 19, 2024

The image above represents force settling ratio. To calculate force settling ratio for fine particles, three essential parameters are needed and these parameters are Density of Particle a, (ρa), Density of Particle b, (ρb) and Density of Fluid (ρf).

The formula to calculate force settling ratio for fine particles:

da/db = [ρb – ρf/ρa – ρf]0.5

Where:

da = Diameter of Particle a
db = Diameter of Particle b
ρf = Density of Fluid

Let’s solve an example;
Find the force settling ratio when the diameter of particle is 20, the diameter of particle is 16 and the density of fluid is 12.

This implies that;

da = Diameter of Particle a = 20
db = Diameter of Particle b = 16
ρf = Density of Fluid = 12

da/db = [ρb – ρf/ρa – ρf]0.5
da/db = [16 – 12/20 – 12]0.5
That is, da/db = (4/8)0.5
da/db = (0.5)0.5
da/db = 0.707

Therefore, the force settling ratio is 0.707.
