Olivine Sand 70 mesh

Low-Free-Silica Blasting Media for Safer Surface Preparation

Olivine Sand 70 mesh is valued for its low free-silica content, which supports compliance with occupational health and safety guidelines during dry abrasive blasting. Its moderate hardness and angular particle shape produce a clean, etched surface profile ideal for coating adhesion without excessive embedment or dust generation.

This 70 mesh grade provides a balance between cutting speed and profile depth, making it a practical choice for general industrial blasting, maintenance painting preparation, and light to moderate rust and scale removal. It can be used in both pressure-pot and suction-fed blast systems.

Typical Applications for Olivine Sand 70 Mesh

• Steel surface preparation: Removes mill scale, light rust, and old coatings prior to painting or metalizing.
• Concrete cleaning: Suitable for light profiling and cleaning of concrete surfaces without aggressive fracturing.
• Maintenance blasting: Used in fabrication shops, shipyards, and structural steel maintenance where silica sand restrictions apply.
• General industrial blasting: Compatible with standard air-blast equipment for a range of substrates.

Selection and Handling Tips

When selecting Olivine Sand 70 mesh, verify that the mesh size distribution aligns with your target surface profile and blast nozzle setup. Finer grades like 70 mesh are typically chosen for lighter profiles or when a smoother finish is required before thin-film coatings. Always confirm the actual particle size distribution (PSD) with your supplier to ensure consistency across batches.

Store olivine abrasive in a dry, covered area to prevent moisture absorption and caking. While olivine can be recycled under controlled conditions, its reusability depends on blast pressure, impact angle, and substrate hardness. Discuss your recycling goals with our team to assess feasibility for your specific process.
