5 Uses For Plastics

How to Choose a Plastics Granulator: A Guide The importance of granulation and size reduction continues to grow today. On the other hand, a granulator is used to cut and reduce the size of plastic fragments into smaller granules that are more manageable. The resultant granules may later be harnessed for other plastic-based objectives or offered in the open market for purchase. It’s in your best interest to pick the best machine when looking for a granulator as it can guarantee effective management of materials costs, facilitate the generation of recycled content, and increase your profits. Here are some essential considerations in the selection of a granulator for chopping scrap plastics:

The first thing that should come to your mind when selecting the appropriate granulating machine is your intended application. 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. The physical size and form of the parts are critical to identify. Then, consider the material itself. Different polymers don’t always exhibit identical reactions, and the reactions of PVC and glass-reinforced plastic are not the same as those for 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 In the selection of your granulator, the rotor is one of the most essential components to take into account. 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. 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. Also, consider chamber size and shape, of which can affect the size of cuts the knives can make with each action.
