Abrasive medium

The effect of the blasting process on the surface depends on many parameters. On the one hand, this concerns the technical design and settings of the blasting machines. The quality of the blasting process depends to a large extent on the abrasive used. The desired result of the blasting, e.g. cleaning, roughening or hardening, therefore also determines the choice of the appropriate blasting medium. Various manufacturers, materials, shapes and sizes are available on the market. The range of possible combinations is therefore very wide. AGTOS blast machines are designed in such a way that turbines and abrasive circuits allow the selection of the ideal abrasive. First the material is determined, then the grain size. A grit diameter of 0.1 mm can hardly be distinguished from dust, but can be used in AGTOS blast machines thanks to easily adjustable wind sifting. At the other end of the size scale are steel balls with a diameter of 3 mm. These are also known colloquially as "cannonballs". The general principle is: as coarse as necessary, but as fine as possible. Steel blasting media The standard material for use in foundries, forges or in steel construction is steel. It is mostly used as cast steel, but cut steel wire also finds many areas of application. As far as steel casting is concerned, the carbon content determines the durability and aggressiveness of the abrasive. Highly carbonised abrasive breaks more quickly. The fracture points are sharp-edged and intensify the steel process. Low carbonised abrasives are considered to be more durable and gentle. Our specialists will be happy to answer the question of when which blasting medium should be used.
