Granulators break down plastics, rubber, foam and other materials into uniform granules or pellets for recycling, reprocessing, and compounding. This category includes knife-and-rotor granulators, crusher-style units, and pelletizers (underwater and strand), varying by throughput, screen size, and cutter configuration. Buyers look at rotor speed, motor power, screen mesh, and hopper/feed design. Granulators are essential for reclaim lines, injection molding feedstock, and reducing waste volume.
Inspect cutter condition, rotor bearings, motor hours, screen condition, and feed/hopper wear. Ask for maintenance records and tests with the material you’ll run.
Match throughput to your production rate and material type. Knife-and-rotor works for most plastics; heavy-duty or multi-shaft for thick or contaminant-filled scrap.
Secure rotors and knives, drain fluids if any, crate or band the unit to a pallet, and verify weight/height for trucks and cranes at both ends.
Lock or remove moving parts, secure the hopper, tag electrical components, clean material from chutes, and document serial numbers and condition photos.
Sharpen or replace knives regularly, inspect bearings and belts, clean screens, check rotor balance, and follow motor service intervals.
Common knives and screens are widely available; confirm lead times for OEM rotors, bearings, and customized components before purchase.
