The particle size distribution of this product is similar to that of SFJ-PLD, which is known for its precise grading and exceptional quality. However, this product is additionally purified using a neodymium magnet to remove iron and other possible free iron compounds, ensuring the quality of colorless and transparent glass.
SFJ-PLDMD: Innovation in Safety and Processability with Dust-Resistant Micronized Silica
The SFJ-PLDMD product is an engineered solution to one of the biggest challenges in industries using micron powders: dust control. It retains all the premium quality features of SFJ-PLDMO ultra-pure silica—high purity, ultra-low iron, and exceptional whiteness—with one key difference: the addition of a precisely controlled moisture content (~0.5%) through an exclusive proprietary process.
This controlled moisture lightly binds the micron-sized particles together, preventing them from becoming airborne during handling, unloading, and mixing. The result is a safer working environment, reduced material loss, and significantly improved performance in automated production processes.
Processed using advanced SANDVIK and AKW production lines, SFJ-PLDMD sets a new standard in occupational safety and health (HSE) while maintaining the precise particle size distribution and exceptional quality comparable to SFJ-PLDMO.
Particle Size Comparison:
The particle size distribution of SFJ-PLDMD is similar to SFJ-PLDMO, offering precise grading and outstanding quality. The main difference lies in iron content: SFJ-PLDMD is virtually free of iron and other iron compounds, which maximizes the quality of clear and colorless glass products.

Explanations and Results
Title: Particle Size Distribution of Silica Sand (Code: PLD)
Columns:
Mesh No.: Aperture size of the sieve.
Size (mm): Particle diameter in millimeters.
Size (µm): Particle diameter in microns.
Sample (%): Percentage retained on each sieve.
Cumulative (%): Percentage of the total sample that passed through each sieve.
Key Findings:
More than 95% of the particles fall within the 0.09 to 0.5 mm range (Mesh 35 to 170).
The highest fraction (36%) is retained on Mesh 50 (0.3 mm).
The sample is free of oversized particles (>0.5 mm) and ultrafine particles (<0.03 mm).
This particle size distribution is suitable for industrial applications such as sandblasting, filtration, or silicon production.
