Olivine Sand 40/60 mesh

Why Choose Olivine Sand for Abrasive Blasting?

Olivine's unique mineral structure—a magnesium iron silicate—provides a distinct advantage in blasting. It fractures upon impact into sharp, angular particles, constantly exposing new cutting edges. This results in a fast, consistent etch on steel, concrete, and other substrates, creating an excellent anchor profile for coatings. Unlike silica sand, which can shatter into breathable, hazardous dust, olivine's dust is heavier and contains no free silica, making it a safer choice for operators and the environment.

Key Features and Benefits

• Low Free Silica Content: A safer alternative to silica sand, helping you meet stringent occupational health and safety regulations.
• High Angularity & Hardness: Mohs hardness of 6.5-7.0 ensures a fast cutting action and excellent surface profile for superior coating adhesion.
• Low Dust Generation: Produces less airborne dust compared to many other expendable abrasives, improving visibility and reducing cleanup costs.
• Versatile Performance: Suitable for a wide range of applications, from removing heavy rust and mill scale to creating a fine profile on softer metals.
• Environmentally Acceptable: Inert and non-toxic, olivine is often permitted for use in environmentally sensitive areas.

Typical Applications for 40/60 Mesh Olivine

The 40/60 mesh size is a versatile workhorse in the blasting industry, balancing profile depth with production speed. Common uses include:

• Structural Steel Preparation: Cleaning and profiling beams, columns, and fabrications before painting or coating.
• Shipyard & Marine Maintenance: Removing old coatings, rust, and marine growth from hulls, decks, and tanks.
• Industrial Plant Maintenance: Preparing process equipment, piping, and storage tanks for recoating.
• Concrete Surface Preparation: Cleaning and roughening concrete surfaces for overlay or coating applications.
• Blasting Delicate Substrates: With careful pressure control, it can be used on aluminum, fiberglass, and other non-ferrous materials where a lighter profile is needed.

Selection and Handling Guide

To get the best results from your olivine abrasive, consider these operational factors. Always match the mesh size to your desired surface profile and production rate. The 40/60 mesh is ideal for a balance of speed and a defined anchor profile, typically achieving a 2-4 mil profile on steel. Use a standard venturi nozzle with a 3/8-inch or 1/2-inch orifice for optimal velocity. Maintain a nozzle pressure of 90-100 PSI and a standoff distance of 18-24 inches. Store bags in a dry, covered area to prevent moisture absorption, which can cause clumping and inconsistent feed in your blast pot.
