RN 20 close-type granulation

RN 20 Series low speed granulators, characterised by a 200 mm diameter with multiple staggered blades and 300 and 450 mm length. A version with open rotor for the recovery of blow moulded sprues is also available.

The most distinctive feature of the RN 2030/2045 is its rugged design, a characteristic uncommon in similar models. The granulation chamber is made of thick steel plates, machined on CNC centres, bolted together, and the blade supports are of forged steel. The continuous cutting action guarantees high performance and the blades can be easily removed for sharpening without any subsequent need of mechanical adjustment after their re-installation. Moreover, two lateral discs running with the rotor prevent friction and damage of the material to be ground against the chamber walls.
