The main capacity of the vacuum recovery system is to recovery the abrasives accumulated in cabins, oil tanks, or on dry ground and it can also be used to clean the abrasives in some complex structures. The vacuum recovery system design is based on the pneumatic conveying system, using high speed air flow to pick up all the abrasives through a wear-resistant suction pipe and convey the abrasives to the sand storage barrel. It’s much more easy for recovery.
