Dual abrasive blast room
As items produced from stainless steel become more common, steel fabricators are required more often to abrasive blast stainless steel products. However this presents a problem as carbon steel and stainless steel products cannot both be blasted with the same abrasive as this would result in ferrous contamination on the stainless steel surface. Stainless steel must be blasted with an abrasive that will not contaminate the surface, ie glass beads, ceramic beads, garnet, aluminium oxide etc.
Lower cost, space saving option
One option would be to have 2 separate blast rooms, one for steel items and one for stainless steel. This is a capital and space intensive solution. Our dual abrasive blast room has been developed to offer a lower cost, space saving option. The blastroom enables both carbon steel and non ferrous items to be blasted using different blasting media in the same facility. Change over from one abrasive type to the other is fully automatic and is achieved by the switch of a button.
Eliminate cross contamination
The recovery of the abrasive is through our W Series pneumatic conveying recovery floor and the different abrasive types are automatically separated into 2 separate storage hoppers ready for reuse. The recovery system is fully inter-locked to prevent cross contamination of the different abrasive types. The contamination of glass beads by steel grit has proven to be less than 0.1%.
