Series 300 BR - Motor output: 22.5 - 30 kW

Single stage shredding of solid start-up lumps

The MG 450/300 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.

Soundproof cabin

Different kinds / versions of sound-proof cabins can be offered optionally.



Low energy requirement

Also the one step size reduction lump granulators are working with low energy motors: 15-30 kW.

Mighty exterior bearings on two sides

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

Cutting equipment

The rigid, distortion-free rotors made of solid material guarentee gentle cutting, also during extremely high peak loads which happens at the step size reduction.

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.
