high-performance turbines                                                  Many different variants                                                               Automation                         

1.Our turbines are solid, well-constructed pieces of machinery. Due to a smaller number of wear parts and high abrasive throughput, they operate extremely economically.

2.Because of the many different variants, it is possible to build the optimal blast machine for the intended application. Besides volume capacities of 50, 90, 180 and 270 litres, etc., users can also select the type of abrasive transport system and cleaning method. Conventional machines are equipped with a screw conveyor. TAA also ofers a vibrating conveyor for transporting abrasive as an available option. This option cleans the abrasive in the lower part of the machine ater the blasting process and then directly discharges impurities and any stray work pieces. Ater the blasting process, work pieces can be removed manually, or they can be fed directly to a work piece conveyor for further transport. This makes the machine easy to integrate into the industrial process.

3.TAA MG machines can be optimally integrated with in- house logistics systems. Custom solutions using special containers have already been successfully implemented.

The work pieces arrive at the loading mechanism in special containers (450 x 300 x 300 mm). The mechanism, which can be loaded from the side, takes the container and empties its contents into the blasting machine. Sensors auto matically control the loading process. The door of the blasting machine closes automatically and the blasting process begins. During this time, the loader returns to its initial position in order to pick up the next container of work pieces. After blasting, the work pieces move onto a
conveyor belt. Waiting at the end of the belt is exactly the same container from which the parts were removed.

Pressing a button on the control panel activates a loading mechanism that directly loads the blast machine. After the door is automatically closed and secured against accidental opening, the pre-defined blasting process begins. When the blasting process ends, the door opens automatically and work pieces are incrementally emptied directly into waiting containers.

 A:Fig. 1: Vibro chute for discharging coarse particles from the abrasive
For turbine wheel shot blasting machines that are operated in foundries, coarse particles must be discharged via a sieving conveyor chute that is installed beneath the blasting chamber (Fig. 1).
 

B:Fig. 2: Magnetic/air separation in a large foundry facility
For cleaning the abrasive an additional cleaning level in form of a magnetic separator is pre-installed to the com- mon air separator (Fig. 2). This serves the removal of aggressive and unhealthy molding sand after shatter- ing from the abrasive circuit.
 It then runs through the so-called air separator and is then returned to the turbines (Fig. 3). Thus the abrasive circuit is closed. The sand is discharged from the system and can usually be reused.
For turbine wheel shot blasting machines that are not installed in foundries, air separation is sufficient for cleaning the abrasive.
In contrast, for systems that are installed in foundries, it constitutes the third cleaning level after the sieving conveyor chute and the magnetic separator.
