Custom designed and built to meet the specific needs of each individual customer.
From the simplest cabin with manual recovery of the abrasive to systems with fully automatic mechanical recovery with scrapers or pneumatic type with collection hoppers.
Structure in steel sections and sandwich-type modular panels with high density insulation and high soundproofing capacity. Internal coating in abrasion-resistant rubber, applied with an easy-to-replace system, in order to guarantee complete protection of the chamber.
The internal lighting is guaranteed by metal halide or LED lamps placed on the roof and protected by transparent lexan panels. The sandblasting operation is carried out by pressing the control lever of the sandblaster placed on the lance.
The projected abrasive falls to the floor and is recovered manually or automatically and conveyed to the mouth of the bucket elevator that lifts it up to the pneumatic separator.
Inside, the abrasive is cleaned and reconditioned.
This eliminates impurities, fragments of abrasive, slag, dust, oxides and calamines.
Therefore, in the lower part of the separator only abrasive is cleaned and selected for the subsequent blasting cycles. Abrasive regeneration is achieved thanks to the self-cleaning cartridge filtration unit which also provides for the dusting of the interior of the chamber.
Types of different abrasive recovery systems
The abrasive is recovered manually by the operator and conveyed into a loading hopper positioned in a corner of the blasting chamber.
The hopper can be buried or remain above ground according to the customer's specific request. From there the abrasive is lifted by a bucket elevator and loaded into the pneumatic separator for its regeneration. The clean abrasive is returned to the sandblaster for subsequent operating cycles.
Automatic mechanical recovery - Scrapers
The system allows to work continuously without worrying about the abrasive spread on the ground during the sandblasting operation.
The system provides for the recovery of the abrasive, its regeneration and return to the cycle.
It is composed of a series of longitudinal rows of scrapers with oscillating paddles in a number proportional to the size of the chamber. The steel blades are mounted on a sliding frame controlled by a pneumatic cylinder.
The abrasive is conveyed in a transversal row of scrapers which deposit it at the foot of the bucket elevator.
The elevator handles the abrasive into the separator for its regeneration.
The clean abrasive is returned to the sandblaster for subsequent operating cycles.
Automatic pneumatic recovery - Tramoggini
The floor of the room consists of many small hoppers in quantities proportional to the surface of the floor.
The air, sucked in by openings positioned on the roof, is conveyed downwards, crosses the hoppers carrying the abrasive and conveys it to a separator cyclone.
The cyclone consists of two concentric cylinders. A downward spiral motion is imposed on the air / dust / abrasive mixture sucked in the gap between the two cylinders.
Due to the centrifugal force, the abrasive, which is the heaviest material, is projected towards the walls of the cyclone and then falls to the bottom where it is collected.
Air and dust instead escape from the inner cylinder and are filtered by the cartridge filter positioned downstream of the system. The abrasive thus selected is returned to the sandblaster for subsequent operating cycles.
