Guide to Purchasing the Right Plastic Granulator

by Josefa Reed

Granulation is the process of reducing the size of a material. Ideally, it is the making of granules from a material. You should note that granules are quite important in the plastic process. With the higher cost of materials and demand for recycled plastic products, granulation has become quite popular. Also, granulation is cost-effective.

You can granulate scrap plastic into small sizes by using a plastic granulator. This type of machine is also called a plastic grinder. You can find more information about plastic granulators on this site. The good thing about having an effective granulating system is that it can help you manage the material cost and increase the recycled content in your plastic products.

To ensure efficient granulation, you have to choose the best granulator that suits your application. Therefore, you should consider a few things such as physical shape and size. Moreover, you should pay attention to the type of material and the amount of plastic you want to granulate.


You should note that you cannot find an all-in-one granulator. That means you need different plastic granulators depending on your application and material for better cost-saving and efficiency. Thus, there is a need to determine the type of chamber size, rotor, and horsepower.

Granulator Components

After determining your need for a plastic granulator, you should consider the different granulator components. The first thing to consider is the rotor. There are three different types of rotors: staggered, open, and closed. When you want to grind thick and large parts, you should consider getting a closed rotor machine. However, if you have thin materials, you should get the open rotor as it ensures there is a smooth flow.

Chamber Size

As you know, a plastic granulator can make your processors quite profitable and efficient. Another thing to consider is the shape and size of the granulator’s chamber. It is quite helpful when choosing a standard and tangential chamber. For the thick material and parts, a regular chamber is enough. If you are recycling plastic buckets, bottles, and large materials, you should get a chamber with tangential feed.


This is another part of the plastic granulator you should consider. It is important because when the part is granulated, the granules go to the screen. The desired granule size is determined by the size of the screen. You should note that the screen size does matter as smaller holes lower its throughput. Also, you should pay attention to how granules are evacuated from the machine. Remember that there are different evacuation methods and the widely used is Airveyor discharge.


To ensure the material is cut efficiently, you need to get an efficient plastic granulator that suits your needs. Nowadays, there are different machines that offer cost-effective solutions when it comes to size reduction of plastic waste. The modern machines are energy efficient and take a small area. When choosing a plastic granulator, you should pay attention to the feed stream and its features.

Remember that buying a plastic granulator is an investment. Therefore, you want to ensure you get the right machine that suits your needs and takes your business to another level.
