Olivine Sand 50 mesh

Why Choose Olivine Sand 50 Mesh for Blasting

Olivine is a magnesium iron silicate mineral. In the 50 mesh grade, it delivers a consistent particle size distribution that supports uniform surface profiles. Its angular grain shape promotes effective cutting and cleaning action without the extreme embedment risk associated with some harder, sharper abrasives.

Key operational advantages include:

• Low free-silica content: Typically below 1% free silica, reducing respirable silica dust hazards compared to traditional silica sand.
• Good dust control: Olivine fractures into larger particles on impact rather than shattering into fine airborne dust, supporting better worksite visibility and air quality.
• Moderate hardness: Sufficient for removing mill scale, rust, and coatings from carbon steel while preserving surface integrity.
• Recyclability: Depending on blast pressure and substrate, olivine can often be recycled multiple times in closed-loop or reclaim systems, improving media cost efficiency.

Typical Applications for 50 Mesh Olivine

The 50 mesh size is a versatile general-purpose grade. It is commonly specified for:

• Steel surface preparation: Achieving SA 2.5 / SSPC-SP 10 near-white metal cleanliness on structural steel, tanks, and vessels prior to protective coating.
• Concrete cleaning and profiling: Removing laitance, dirt, and coatings from concrete floors, bridges, and precast panels.
• Stone and masonry restoration: Cleaning brick, stone, and masonry facades without excessive substrate damage.
• Industrial equipment maintenance: Stripping paint, corrosion, and scale from machinery, pipes, and process equipment.

Handling and Selection Guidance

To get the best results from Olivine Sand 50 mesh, consider these practical points:

• Nozzle and pressure matching: A 6 mm to 8 mm nozzle orifice with air pressure between 6 and 7 bar (90–100 psi) is a common starting point. Adjust based on your compressor and desired production rate.
• Stand-off distance: Maintain a consistent nozzle-to-work distance of 300–500 mm to balance cleaning speed and media breakdown.
• Moisture control: Store olivine in dry conditions. Wet or damp media will clog metering valves and hoses, causing inconsistent feed.
• Dust extraction: Even with low-dust media, always use properly rated respiratory protection and ensure adequate ventilation or dust extraction in enclosed blasting environments.
