What size glass beads for sandblasting?

Sandblasting involves using high-velocity streams of abrasive materials to clean, etch, or shape surfaces. Glass beads are popular for sandblasting due to their uniform size, low dust emission, and ability to produce a smooth finish on various surfaces. When selecting the right size of glass beads for sandblasting, several factors need consideration.

Size of the Surface to be Sandblasted

The initial factor to consider is the size of the surface. For smaller surfaces, smaller beads are appropriate, whereas larger surfaces require larger beads. The bead size should correspond to the surface area you need to cover.

Type of Surface to be Sandblasted

Next, consider the type of surface being sandblasted. Different surfaces necessitate different bead sizes for optimal results. For instance, softer surfaces like wood or plastic require smaller beads, while harder surfaces such as metal or concrete need larger beads.

Desired Finish

The desired finish is another critical factor. For a smooth finish, smaller beads are preferable. Larger beads are more suitable for a rougher finish. The bead size will also affect the etching depth on the surface.

Equipment Being Used

The type of equipment also determines the required bead size. Different machines have specific bead size requirements. Consult the manufacturer's instructions for the equipment to identify the best bead size.

Mesh Sizes

Glass bead sizes are typically classified by mesh sizes, which refer to the number of openings in a sieve per linear inch. Higher mesh numbers indicate smaller beads. Here are common mesh sizes for sandblasting:

• 30-40 mesh: Ideal for removing rust and paint from metal surfaces. Also good for etching glass and stone.
• 40-60 mesh: Suitable for cleaning and polishing aluminum and stainless steel surfaces. Creates a matte finish on metals.
• 60-80 mesh: Great for removing light rust and paint from softer surfaces like wood and plastic.

• 80-100 mesh: Provides a smooth, satin finish on metals. Removes paint and light rust from delicate surfaces.
• 100-170 mesh: Useful for creating a fine, polished finish on metals. Also removes surface blemishes from plastics and composites.

It's important to note that these guidelines are general, and the bead size you select will depend on the factors mentioned above.

Conclusion

Choosing the appropriate glass bead size for sandblasting is essential to achieve the desired finish and protect the surface. Consider the surface size, type, desired finish, and equipment when selecting bead size. Starting with a smaller bead size and increasing if necessary is recommended to avoid surface damage.

Glass beads are a commonly used abrasive blast media. All bead blasting cabinets at Raptor Blasting Systems can utilize glass beads. Use the glass bead media size chart to see what sizes correspond to each brand and spec.

Different sizes and diameters of glass beads are used for various jobs, much like varying grades of sandpaper. For quick cleaning or stripping of surfaces, choose No. 7 or No. 8.

In industrial blast cabinets, glass beads aid in removing small burrs, cleaning, peening, honing, polishing, blending, and finishing. They offer just the right stress relief without causing damage for delicate metal or thin welds.

Glass beads can typically be recycled 30 times under normal use.
