The Machine

A special feature of the continuously operating pass-through machine is the constant travelling speed of the workpieces. The ability to adapt the moving speed of the workpiece and the wheel power ensures that the machine can be easily and smoothly integrated into an existing production line.The abrasive is pre-accelerated very efficiently by the ANTAI blast wheels, allowing for short treatment times and reduced abrasive consumption when compared to conventional blast wheels. Maximum coverage of the workpiece is achieved by the blast wheels being arranged in an “X” alignment, diagonally to the moving workpiece. In this formation, the leading edges of complex components, welded sections and flame-cut parts can be thoroughly blasted.



The Process
The workpieces are carried on rotating hooks on the Manually operated monorail or conveyed automatically on a (optional) Power & Free conveyor to the blast cabinet where they are blasted by blast wheels. The blast cycle runs in accordance with the preset blast time. When the blast wheels stop, the door is opened and the hook exits automatically.
Continuous Overhead Conveyor
The continuous overhead conveyor allows the workpieces to move with constant speed through the machine. The conveyor consists of a chain and trolley system suspended from a monorail, and can be driven at constant speed or can be indexed.



The transport speed or index time can be coordinated to the blast wheel power and surface finish required. The system can be easily extended to suit factory layout and integrated with pre- and post-blast operations.
Special Features and Options
Standard machine: Used abrasive and fines fall through the abrasive collection hopper beneath the blast cabinet, and are transported via a screw conveyor to a bucket elevator, and to the Abrasive reclamation unit.


Abrasive Removal
During the blast process, dust, broken abrasive and other solid particles or contaminants (fines) are generated by the rust and scale removed from the workpieces. The fines are separated in the abrasive reclamation unit which is individually adjustable to the different types and sizes of abrasive.
The Abrasive reclamation unit consists of an impact separator and a cartridge filter. The impact separator removes the fines from the abrasive and serves as a certified spark extinguisher and meets all ATEX regulations.
The cartridge filter provides the necessary negative pressure to remove dust. lt can be installed separately beside the shot blast machine. The filter is automatically cleansed by compressed air pulses which are adjustable in intensity and duration. All elements of the filter unit are free from ignition sources.
Alternatively, wet filter units can be used for the necessary dust removal. This is often applied in aluminium die casting.

Vibro Conveyor

In place of the standard screw conveyor, a vibro conveyor can be used to transport abrasive from the blast cabinet to the bucket elevator. The sieve installed in the vibro conveyor separates coarse fines from the abrasive. For dust removal, the conveyor is linked to the dust filter of the central machine.
Vibro Sieve
For a blast process without interruption, a vibro sieve is used to clean abrasive.
The vibro sieve is used after the abrasive reclamation unit and sieves coarse particles, such as flashes from aluminium diecasting workpieces, from the abrasive so that they do not affect the blast process.
The sieve is installed above the silo. It is driven by two vibro-motors and set in motion similar to a shaker sieve. A targeted sieving of unwanted fines is achieved with the mesh size adapted to the process. Fines are automatically fed into a bin via a downhose.
Lateral flaps allow easy access to the sieve for ease and maintenance.

Magnetic Separator

The magnetic separator increases your profitability by reducing machine wear and reducing abrasive consumption.
Moulding and core sand on castings is removed during the blast process. As they cause high abrasion they must be separated from the ferro-magnetic abrasive quickly and efficiently. This is performed in the magnetic separator.
Two rollers with adjustable magnetic fields and a sieving box separate the moulding and core sand and fines from the reusable abrasive, in this way only 0.2% of the weight remains. This reduces wear and abrasive consumption and leads to higher profitability for you.
