Important Considerations When Buying a Plastics Granulator

Granulation and reduction of size keeps increasing in significance every day. But a granulator is needed in the chopping of scrap plastic and reduction of size into more manageable tiny granules. 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.

Here are some essential considerations in the selection of a granulator for chopping scrap plastics:


Understand Your Application

When choosing the granulating machine, you want to start with understanding your application. Step one, understand the material along the lines of the amount of it you want cut into granules as well as how big the scrap plastics are. It's very helpful to figure out the physical size and shape of these components. Next, turn to the material itself. Different materials don't have the same reactions; for example PVC and glass filled polymers have different characteristics from polypropylene. 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. In the world of granulation, it's impossible to find an perfectly all in one machine, and the use of one solution for all materials can lead to operational inefficiency as well as additional costs over the long term. Having said that, consideration of all essential elements of your application and materials proves important in the selection of the right rotor type, chamber size, and horsepower capacity needed to deliver superior results.

Consideration of Granulator Parts

When selecting your granulator, the rotor is among the most critical components to look at. Choose an open rotor for proper handling of thin walled scraps. The open concept lets materials flow effectively. The best for large, thick scraps is a closed rotor design, while a staggered rotor, which has more cuts for each revolution, is a hybrid of the other two designs.

You may also consider the type of engagement between the fly knife and bed knife because it has a relationship with horsepower requirements. Offsetting the two knives creates a scissor cut. You may have a granulator with two bed knives, although a machine can sport three or four to boost its cutting function. Also, consider chamber size and shape, of which can affect the size of cuts the knives can make with each action.  Please view this site  https://en.wikipedia.org/wiki/Granulation_(process) for further details.
