Less dust with the slow speed generation

The company Hellweg Maschinenbau GmbH & Co. KG has extended the new generation of slow-speed machinery with two types. New in the slow-speed machinery are the working
widths of 150 mm and 330 mm. The slow-speed cutting mills work according to the grinder principle, guaranteeing constant-sized, dust-free grains - without the use of a sieve. Both sprues and thick-walled parts can be ground owing the precrushing between the roller mills. The compact, space-saving design with motor output from 1.1 - 2.2 kW makes it possible to use the granulator directly on the injection moulding machine. The low number of revolutions of 25 r.p.m. and the solid construction of the cutting chamber only tolerate a minimal development of heat. The cutting chamber is divided into two levels and can be completely opened for cleaning. The complete milling plant is bared and as a result of this easy of access.

In addition, the MRS-series has been extended by the MRS vertical. The CD/DVD sprue recycling system works in vertical erected position. This absolute novel concept allows an operation directly inside the injection moulding machine, without space required. With a weight of only 43 kg the machine also can be fitted on movable units. The cutting chamber, inlets, outlets, and the rotor of the MRS vertical are made of stainless steel. The motor output is 0,55 kW.

Hellweg Maschinenbau GmbH & Co. KG has extended its range of products in the field of cutting mills, too. The extensive range of models has been completed by the Cutting mill Type M 410/260. This cost-effective cutting mill has a working width of 410 mm, a rotor diameter of 260 mm and a motor output of 5.5 to 11 kW. It is an all-round machine for grinding PET-bottles, foils, plates, sprues and lots more. The company Hellweg Maschinenbau GmbH & Co. KG is exhibiting its mills at the Fakuma/Friedrichshafen in autumn 2002.
