Series 80 / MRS (Material Recycling System)
MRS - (CD/DVD-Sprue Grinder)
The production of pre - recorded/recordable/rewritable optical media (CD, DVD & smart cards) generates tons of so-called ``sprues`` annually. The usual way to dispose of this production wastes is collection, storage and finally dispatching to a raw material supplier.
This Material Recycling System (MRS) recycles these sprues in a closed loop process: The MSR unit collects sprues directly from the moulding machine, grinds them and re-injects them with the ``virgin`` polycarbonate (PC).
The closed loop system prevents impurities from mixing with the recycled polycarbonate and therefore maintains the PC`s quality.
Series 80: High Quality In-House Grinder
This extremely small and efficient In-House Grinder has as a variety of uses for example; it can directly be fitted in the bed of an injection-moulding machine. If for industrial use or in a lab, this series has been constructed for continuous operation. Because of the expansive list of options this mill is available for a wide field of applications.
Advantages:
- Quick screen and knife change
- No need to adjust the rotor knife
- Knives can be reground several times
- Quick and easy to clean
- Maintenance-free
- Ideal granulate quality
- Outer bearing assembly fitted as standard, ensuring protection from dust
- Opening without tool
Series 100 – Beside The Machine Granulators
Highest ground material quality through fast material delivery.
The Hellweg 100 series beside-the-machine granulators, represents an economical solution for use alongside injection moulding machines with a medium amount of sprues to be processed. The space needed is extremely low due to the compact design.
These granulators guarantee optimum material handling and fast material delivery due to the design of the grinding chamber. In addition, the use of co-rotating rotor discs prevents ground material from becoming trapped between the rotor and the wall of the enclosure. Thermal degradation of the ground material produced is consequently largely prevented.

Series 150 - Slow-Speed Granulators
A very compact mill for incline, which works immediately at the production plant and the applicability of this all-round mill for incline are nearly infinite.
Suitable for all plastics, for GFK-plastics as well, but for this the mill has to be offered in wear-resistant quality.
Standard sieves are offered with a size of 5-8 mm and guarantee invariable size of particles and exclude long points of sprues.
Advantages:
- Quick screen and knife change
- No need to adjust the rotor knife
- Knives can be reground several times
- Energy-saving and performance-enhancing diagonal cut
- Solid rotor with high moment of inertia
- Outer bearing assembly fitted as standard, ensuring protection from dust
- CE certified
- Opening of the machine without tool
Series 200 - Slow-Speed Granulator
A very compact mill for incline, which works immediately at the production plant. The applicability of this all-round grinder for incline is nearly infinite.
This grinder is also ideal for PET. The cutting chamber will be fastened with an angle directed by Hellweg (to force through hollow bodies), the mill can also be used for plates, sprues and foils.
Standard sieves are offered with a size of 5-8 mm, and guarantee invariable size of particles and exclude long points of sprues.
Advantages:
- New innovative access for cleaning
- Easy handling
- Solid screwed/plugged chamber
- Quick screen and knife change
- No need to adjust the rotor knife
- Knives can be reground several times
- Solid rotor with high moment of inertia
- CE certified
- Opening of the machine without tool
Series 250 - Slotter
The cutting mill with advanced shredder and toothed roll.
This series can be used, only if least possible parts of dust may remain. We emphasize: ``least possible parts of dust``, because often there is talk about no dust in the granulated material.
The ``slotter`` is very easy to handle for example the divided cutting chamber, as a result of the two opening possibilities the mill is very easy to access and clean. This series guarantees best quality of granulated material as well. But attention must be paid to the slower grinding operation. Also attention must be paid to the fact that the slotter can`t cut soft plastics (PP, PE) and can only condition cut hollow bodies.
Advantages:
- Slow runner (25 R.P.M.)
- Zyclon / fan connector
- Easily adjustable counter-knives
- Power-economizing offset arrangement of the rolls
- High-torque geared motor
- Reduction without a screen
- Compact, space-saving construction
- External double-sided bearing, dust resistant
- Double-sided external bearing for dust protection
- Long-life knives and rotor
- Maintenance-free
- Virtually maintenance free
- Low operating noise (approx. 72-78 dBA)
