Central granulators

Hellweg Maschinenbau

Series 180 - Motor output: 3 - 5.5 kW

Central processing, high flexibility and reliable grinding

Operation of only one central Hellweg granulator can be advantageous, compared with buying several beside-the-machine granulators. Lower investment costs and better machine utilisation can then mean greater profitability.

On-line recycling directly at the injection moulding machine is not always possible. So rejected parts, sprues and runners can be collected within a plastics processing operation and passed to the Hellweg Series 180 central granulator fitted with extraction equipment.

Both lightweight and thinwalled, as well as heavy and thick-walled parts can be ground.

The benefits:

performance-enhancing diagonal cut
ideal granulate quality with very low dust
outer bearing assembly fitted, dust protection
wear resistant versions for reinforced plastics
structural design for easy, complete cleaning through absence of dead corners
stiff, non-twisting solid rotors
high performance belt drive
high throughput at low drive power
direct mounting of the knives on solid rotors
eliminating need for rotor knife adjustment
quick sieve and knife change
both rotor and stator knives can be re-sharpened many times
sieve sizes Ø 4 - 30 mm
