Beside-the-machine

Hellweg Maschinenbau

Series 150 - motor output: 1.5 - 4 kW

Revenue source: raw material savings through return of sprues

The Hellweg 150 series beside-the-machine granulators can be connected very easily to one or more injection moulding machines, due to their especially flat construction.

Extremely bulky sprue cores, sprue gating and complete sprue and runner systems can be removed after opening of the moulding tool and then ground on the spot. Introduction of material can

take place as desired, with a chute, free-fall hopper or conveyor belt. Material can be removed by connecting freely available standard extraction fittings. A tall rack is offered as an option to fill the ground material into a bulk container or bags. When fitted with an appropriate feeding equipment, the machines are used to process film edge strips.

The benefits:

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