Important Considerations When Buying a Plastics Granulator Granulation and reduction of size keeps increasing in significance every day. And a granulator is a machine that cuts and reduces the size of scrap plastic into smaller granules for easier management. The generated granules could then be utilized in other plastic manufacturing or sold in the open market. When shopping for a granulator, you need to choose the right machine to ensure efficient management of the costs of materials, help deliver recycled content, and boost the bottom line. Below are a few important points to assess when picking a granulator for cutting scrap plastics:
The Essentials of Tools – The Basics
Understand Your Application

The job for which you’re selecting the ideal granulating machine is the first issue you need to understand. First, describe the material in terms of how much of it you need to chop into size as well as how bulky the scrap parts are. It’s very helpful to figure out the physical size and shape of these components. Next, focus on the material itself. Various plastics don’t always produce the same reactions, and PVC and glass-reinforced plastics exhibit different reactions from polypropylene, for example. And if you’re using several feed streams, it helps to work out percentages for them. When you’re handling roughly 95% sprues and runners in addition to the sporadic purgings, it’ll be more effective to have a solution for your sprues and runners while allocating another system for the purge. As far as granulation is concerned, there’s barely a single system that’s seamlessly all in one, and any consistent use of a single solution for all solutions may result in effective operations and higher costs over the long term. With that said, understanding all important aspects of your application and materials will help determine the right kind of rotor, size of chamber, and amount of horsepower required to do the job perfectly well. A Look at Granulator Parts When selecting your granulator, the rotor is among the most critical components to look at. You may prefer an open rotor for processing fragments with slim walls. The open concept lets materials flow effectively. The perfect design for large, thick fragments is a closed rotor, while a staggered rotor, which combines the best of the other two, provides for more cuts with every revolution. It may also help to look at the mechanisms between the fly knife and bed knife as horsepower preferences may be affected. Counterbalancing the two knives generates a scissor cut. You could select a machine with two bed knives, or prefer one with three or four for improved cutting action. Likewise, take chamber size and shape into account as these do impact the size of the chunk the knives can bite each turn.
