How to Calculate and Solve for Specific Surface Area | Mineral Processing
Last Updated on October 4, 2021
The image above represents specific surface area.
To compute for specific surface area, two essential parameters are needed and these parameters are Proportionality Constant (KL) and Size of Particles (D).
The formula for calculating specific surface area:
A = KL/D
Where:
A = Specific Surface Area
KL = Proportionality Constant
D = Size of Particle
Let’s solve an example;
Find the specific surface area when the proportionality constant is 25 and the size of particle is 5.
This implies that;
KL = Proportionality Constant = 25
D = Size of Particle = 5
A = KL/D
A = 25/5
A = 5
Therefore, the specific surface area is 5 m².
Calculating the Proportionality Constant when the Specific Surface Area and the Size of Particle is Given.
KL = A x D
Where:
KL = Proportionality Constant
A = Specific Surface Area
D = Size of Particle
Let’s solve an example;
Find the proportionality constant when the specific surface area is 10 and the size of particle is 4.
This implies that;
A = Specific Surface Area = 10
D = Size of Particle = 4
KL = A x D
KL = 10 x 4
KL = 40
Therefore, the proportionality constant is 40.
Calculating the Size of Particle when the Specific Surface Area and the Proportionality Constant is Given.
D = KL / A
Where:
D = Size of Particle
A = Specific Surface Area
KL = Proportionality Constant
Let’s solve an example;
Find the size of particle when the specific surface area is 12 and the proportionality constant is 48.
This implies that;
A = Specific Surface Area = 12
KL = Proportionality Constant = 48
D = KL / A
D = 48 / 12
D = 4
Therefore, the size of particle is 4.
