Background

Abrasive media


The selection of a particular medium is always conditioned by the type of work to be performed and by the material which has to be treated.

The type of abrasive used in a particular application is usually specific to the blasting method. Dry Abrasive Blasting is usually done with sand, electro corundum, silica carbide, plastic media, metallic grit or shot. Wet Blasting is usually done with sand, glass beads, or any materials that will remain suspended in water.

The Technical Support team at FerroECOBlast has been specially trained to supply our customers with the correct solutions for a multitude of applications. They can confidently recommend the best abrasive medium for any specific use across a wide variety of industries.

When judging an abrasive's overall economic value, factors such as:

  • abrasive cost
  • equipment cost
  • labor cost
  • cleaning rate
  • disposal and cleanup expenses
  • and product reusability should be considered.

Time spent on examining a blast job from all perspectives can lead to significant cost savings. These cost savings can be achieved by determining the nature of the surface to be cleaned, defining the cleanliness required for the coating to be used, choosing the proper abrasive, optimizing the use of equipment and personnel, and taking into consideration the conditions and restrictions under which the work will be done.

Three main characteristics:

The effect of abrasive material is caused by its three characteristics: shape, hardness, and particle size.

Particle Shape - Individual particles that have points and edges such as blocky or needle-shaped particles will cut and strip away surface material on impact. Spherically shaped particles do not have any cutting edges and are used to pound or "peen" a surface.

Hardness - The hardness of a selected medium determines the ability of the particle to remove layers from the workpiece material. Harder particles will be more aggressive. The hardness of abrasive media is measured using the Mohs scale.

Particle Size - A larger particle generates a greater impact force as it strikes the workpiece. This has two effects. The first is that it removes material faster. The second is that it tends to produce a heavier texture or rougher surface on the basic material.
