High precision feeders for tablets

The tablets made ​​from compressed powder must be implemented with caution. So, the level of friction applied to the material must be kept as low as possible.

Moreover feeding of pyrotechnic tablets requires:

• Accurate feeding for a strict control of the pyrotechnic reaction.
• Friction free operation to avoid self ignition risks.
• Short dosing time, consistent with the high cadency production lines of automotive industry.
• Machines easy to clean, without retention area.

Feeding of tablets Ø 6.4 mm,

• set point: 20 g to 70 gram
• dosing time < 5sec,
• dosing accuracy ± 2 tablets.

To optimise accuracy and short dosing time, the feeder is designed with 2 feeding corridors:

     2 corridors open + high frequency
     1 corridor open + average frequency
     1 corridor open + low frequency

The switching points are managed by the MCPI batch controller, and are fully memorised.

Feeding of tablets Ø 3.2 mm,

• set point: 11 g
• dosing time < 4sec,
• dosing accuracy ± 2 tablets.

Feeding of tablets Ø 3.2 mm,

• set point: 0.3 g to 1.3 gram
• dosing time < 3 sec,
• dosing accuracy ± 2 tablets.

Feeding of tablets Ø 5.5 mm,

• set point: 500 g
• dosing time < 10 sec,
• dosing accuracy ± 0.3 g.

Optionally, the dispenser can be automatically refilled with a vacuum conveying system.
