Lump granulators

Hellweg Maschinenbau

Series 260 BR - Motor output: 11 - 15 kW

Single stage shredding of solid start-up lumps

The MG 240/260 BR lump granulator enables single stage shredding of solid start-up lumps, thick plates and similar items. The rotor of the lump granulator is made from one piece of metal and therefore has enormous stability in transfer of even high torque.
The U-CUT geometry used for the blades enables a cutting principle that is based on a so-called “peeling cut”, combined with limitation of cutting depth. This prevents the rotor blade from penetrating too deeply into the plastic lumps being shredded. The material is “peeled off” from the lumps so that blockage of the rotor is prevented and fast and energy-saving shredding is guaranteed. An entire sound protection can also be offered as an option.

The benefits:

single stage shredding of solid start-up lumps
stiff, non-twisting solid U-CUT rotor
ideal granulate quality with very low dust
highly precise production, heavy housing welded
outer bearing assembly fitted, dust protection
wear resistant versions for reinforced plastics
structural design for easy, complete cleaning
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
