Blasting sands

are used for surface treatment by blasting. In this process rough and loose dirt is removed.

In most cases glass beads, steel balls, blast furnace slag or corundum (aluminous oxide abrasive) are used for blasting. The shape of the blasting powder is spherical or edged and mainly used are mineral and metallic bulk solids. Synthetic abrasives are rarely used. Besides the widely used glass beads a mineral abrasive is corundum (Al2O3). Both of these are highly abrasive and become recycled after use. In the recycling process the total amount of abrasive is collected and screened. The remaining coarse material is added to the fresh abrasive and hence multiple used. The separated fine material (dirt and broken particles) becomes disposed.

In the supply of screening machines for abrasives the highly wearing products are the main challenging point. A sufficient wear protection has to be provided in any case. Screening machines designed as long stroke type or tumbling screens as well as screens with linear motion are not recommendable. Considerable wear at the screen itself and the sensitive screen cloth caused by the translatory motion of these types of machines is unavoidable.
