What Is Mesh Size?
Mesh size refers to the measurement of the size of particles or granules that can pass through a wire mesh screen. It is defined by the number of openings per linear inch of screen—so, for example, a 60 mesh screen has 60 openings per inch.
In the context of charcoal production, mesh size is crucial in grading charcoal powder before briquetting. It directly affects the texture, compressibility, and consistency of the final product.
Why Mesh Size Matters in Charcoal Production
Determines Particle Fineness
Mesh size controls how fine or coarse the charcoal powder is. This affects how well it binds during compression and how dense the finished briquette will be.
Influences Briquette Strength
Uniform mesh sizing helps ensure consistent compaction, which results in stronger, less breakable briquettes.
Affects Combustion Behavior
Finer particles typically ignite faster and produce smoother burns, while coarser particles may improve airflow and burn duration in certain formats.
Supports Product Standardization
Controlling mesh size allows manufacturers to meet OEM specifications, especially for private-label or export clients who expect batch-to-batch uniformity.

Common Mesh Sizes in Charcoal Processing
Below 40 Mesh (Coarse)
Used for industrial applications or when airflow and loose packing are acceptable. Less common in premium briquette production.
40–60 Mesh (Medium)
Balanced size used in many standard barbecue and shisha briquettes. Offers good compaction and combustion properties.
Above 60 Mesh (Fine)
Preferred for high-quality shisha charcoal. Finer particles create smoother surfaces, denser briquettes, and more stable combustion.
How Mesh Size Is Measured and Controlled
Sieving Process
Charcoal powder is passed through vibratory sieves or rotary screeners equipped with different mesh sizes to classify the particles.
Quality Control Sampling
Production teams routinely test particle distribution to ensure the material meets defined mesh size ranges before it enters the mixing and pressing stages.
Adjusting Based on Product Type
Different briquette formats (e.g., cubes, hexagonal sticks, tablets) may require adjustments in mesh size to optimize performance and strength.
Impact of Mesh Size on Final Product
Visual Appearance
Finer mesh powders result in smooth, polished-looking briquettes—ideal for premium branding.
Breakage Resistance
Uniform mesh distribution improves internal bonding, which increases mechanical strength and reduces product loss during packaging or transport.
Ash Formation
Excessively coarse particles may contain impurities or uncarbonized residues that increase ash content.

Did You Know?
Top-tier shisha briquettes often use charcoal powder between 60 and 80 mesh, achieving a near-perfect balance of density, smooth ignition, and minimal crumbling—key attributes for luxury lounges and global premium brands.
