Strand Pelletizing

Within the strand pelletizing process the extruded, cooled and dried plastic strands are taken into the strand inlet. The strands are caught by both feed rolls and transported to the cutting section. The upper feed roll is pressured.

The cutting section consists out of a stationary bed knife and a rotating cutting rotor. Between the edges of the bed knife and the cutting rotor the plastic strands are cut into regular, cylindrical pellets.

The accelleration of the cutting transfers the pellets into the pellet outlet. From there they are going to the following components, such as vibration screens or conveyors.
