What does a granulating machine do?

A granulator reduces larger components, such as plastics and bottles, and reduces them to a particle size.

  1. How is a Shini USA granulator different from its competitors?
    At Shini USA, we are committed to providing 100% customer satisfaction. This is why all of our granulators and products meet or exceed quality standards. Plus, our products are also readily available and affordable.
  2. What type of material is used for the knives?
    Our granulating machines contain D2 hardened knives, which offer excellent wear and abrasion resistance.
  3. What’s the difference between an open rotor and a closed rotor granulator?
    Open rotors are designed for less dense parts such as bottles, bottle closures, thin wall housings, thin extrusions and film. Closed rotors are for more dense materials and those with thicker profiles.
  4. Are electrics and/or a cyclone blower included in the price?
    Yes, electrics and a cyclone blower are included in the price of the granulator machine.
  5. What safety features does a Shini USA granulating machine have?
    Each machine has an emergency stop button and a main power disconnect. Other safety features such as finger-safe components, dual electrical safeties, motor overload and safety interlocks vary per machine.
  6. How often should I have my blades re-sharpened?
    There is no need to re-sharpen your blades. The cassette knives can be replaced easily and economically, eliminating the high costs of sharpening and resetting knives.
  7. What are the capabilities of Shini USA’s granulating machines?
    The low-speed granulators have a throughput of 100 to 286 lbs/hr. Our staggered blade granulators have a throughput of 230 to 900 lbs/hr and our central granulators have a throughput of 1350 to 5000 lbs/hr.
  8. How do I know which granulator is right for me?
    Granulators are usually classified into two groups: beside-the-machine models and larger models, usually called central granulators. The smaller models are typically used for smaller volumes of parts, sprues and runners, while the central granulators are often located in a separate room and used for large volumes of scrap.
