Recyclable abrasives
Recyclable abrasives are used in blast rooms, blast cabinets, vacuum blasting machines and other systems where they can be collected and cleaned to be reused again and again.
Type of contamination, material type, finishing requirements and surface roughness are all factors that determine the right choice of abrasive. With the right type and grain size, the desired blasting result is achieved in the shortest possible time and at the lowest possible cost.
Gritco has a limited selection of blasting media in its range but our experienced dealers often offer a wider range of options. Together, we can help you choose the right abrasive for your applications.
Recyclable abrasives can be divided in different groups of metallic and non-metallic abrasives and angular or round shaped ones.
To avoid containments which can result into corrosion, non-ferrous objects are generally treated with non-metallic abrasives. For all others materials also metallic abrasives can be used.
Angular shaped abrasives have a good 'chiselling' effect and are therefore used to remove mill scale, rust and paint. Using angular abrasives also results in a surface roughness which is required for e.g. coating systems or metallizing.
Round abrasives have a more 'polishing' effect and are mainly used to create a cosmetic (semi-)gloss finish of objects. Round abrasives are also used with wheel blasting machines or for shot peening processes.
Many manufacturers have given brand names to their products but below you will find some examples of recyclable abrasives by the basic material name.
Non-metallic - Angular
Aluminium oxide (corundum), Silicon carbide, Plastic media
Metallic - Angular
Steel grit, Chilled iron grit
Non-metallic - Round
Glass beads, Ceramic beads, Stainless steel shot
