Particle Size Distribution Percentage Calculator

The Particle Size Distribution Percentage Calculator is a versatile tool designed to determine the proportion of a specific size fraction in any particulate material sample. It supports flexible labeling and can be used in various industries such as mining, food processing, pharmaceuticals, and material science.

Historical Background

Understanding particle size distribution is essential in many industrial and scientific fields. From sieving in early metallurgy to laser diffraction in modern laboratories, tracking how materials break down or are processed has helped optimize performance, quality, and energy consumption.

Calculation Formula

\[ \text{Percentage of Fraction} = \left( \frac{\text{Weight of Target Fraction}}{\text{Total Sample Weight}} \right) \times 100 \]

Example Calculation

If you have a 1,000g sample and 300g of it corresponds to particles larger than 75μm:

\[ \text{Percentage of >75μm} = \left( \frac{300}{1000} \right) \times 100 = 30\% \]

Importance and Usage Scenarios

• Mining & Geology: Evaluate grinding efficiency or ore properties.
• Pharmaceuticals: Ensure uniform particle size for drug delivery.
• Agriculture: Measure grain or soil composition.
• Construction Materials: Analyze sand or cement mixtures.

Common FAQs

1. Can this calculator be used for multiple sieve sizes?

   • Yes, just repeat the process for each sieve fraction and label them accordingly.

2. What if the percentage exceeds 100%?

   • That indicates an error in measurement—ensure total and fraction weights are accurate.

3. Is this tool only for dry samples?

   • No, it can be used for both dry and wet samples as long as weight measurements are precise.
