Pelletizers

Strand pelletizers include micro-pelletizer line, which makes pellets 0.02 x 0.02 in. and 0.06 x 0.06 in. for feeding small extruders in the 0.25- to 0.5-in. range. Pelletizer converts to a two-roll puller or torque winder. Cantilever design permits ready access to working components for cleaning and maintenance.

Also larger (two-in.-wide) two-function pelletizer. Both nip rolls have pneumatically adjustable pressure and are mechanically driven for pulling irregular or slippery strands. Quick-change components for fast cleaning or service. Quick-change parts also convert unit to a two-roll puller with both nip rolls driven for pulling rod, strips, tubing and profiles.
