Hellweg Series 300
High performace granulators for plastics

FLEXAL Machinery & Automation:  Home > Granulators > Series 300

Series 300 - Motor output: 7.5 - 30 kW

High performance granulators for heavy parts and high throughput

The Hellweg 300 series granulators enable gentle and thorough granulation of thick-walled mouldings, sheets, sprue cakes, pipes and profiles, etc, on account of the extremely high stability of the entire machine housing and through the high moment of gyration of the massive rotor that is made from one solid piece of metal.

A special rotor (BR version) enables single stage granulation of even extremely massive lumps from production start-ups.

Exterior bearings on two sides

Exterior bearings for the rotors on both sides prevent ingress of dust and contamination of the ground material by lubricants and thereby guaranteed long bearing life.

Working widths for all tasks

The series 300 central granulators are offered in working widths of 300-900 mm.

Extraction equipment

When fitted with a fan, the ground material is sucked directly out of the collection tub.

Cutting equipment

The rigid, distortion-free rotors made out of solid material guarantee gentle angled cutting, also during extremely high peak loads.

High impetus blades

Additional high impetus blades produce high torque and thereby increase the power of the rotors. This enables optimum granulation of large and heavy parts, as well as tasks involving large quantities.
