4 Lessons Learned: Resources
Useful Tips for the Selection of a Plastics Granulator The importance of granulation and size reduction continues to grow today. 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. Here are some essential considerations in the selection of a granulator for chopping scrap plastics:

Understand Your Application
The Essentials of Tools – Revisited
When choosing the granulating machine, you want to start with understanding your application. Firstly, define the material in relation to the amount of it you need granulated to size and the bulkiness of the scrap parts. It’s necessary that you determine the physical size and shapes of these parts. 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 when you’re utilizing a number of feed streams, it is important to assign them percentages. In the event you handle 95% sprues and runners, and purgings occasionally, you’re better off dedicating a solution to sprues and runners while identifying a disparate tool 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. 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 The rotor is one of the most important granulator parts to consider when buying your machine. Choose an open rotor for proper handling of thin walled scraps. 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. You may also consider the type of engagement between the fly knife and bed knife because it has a relationship with horsepower requirements. The two knives are offset to produce 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. Similarly, don’t forget chamber size and shape as these have a bearing on the extent of cut the knives can deliver with each action.
