Most customers identify plastic granulators as a recycling model for waste management, especially plastics. There are different types of granulators depending on the application or intended use. In addition, their sizes vary to accommodate different sizes of materials. When planning to invest in such equipment, picking the right one may seem like an easy process but ends up challenging you, and you wonder exactly what you want.

What You Need to Know About Plastic Granulators

What is the Purpose of a Plastic Granulator?

Some people might have heard about these machines but can’t tell what they do or how they work. The main objective is to convert any material, in this case, plastic, from its current condition to granulates that facilitate the reusing of the materials. The granulates produced are high-quality due to various reasons.

1. What is a High-Quality Granulate?

You can define this granulate based on three elements: size, cleanliness, or proper sanitation and uniformity.

a. Size

The size of the granulate on the screen brings about balance between the throughput you intend to have and the end product that is the final size of the granulate. The ultimate granulate size is usually compatible with the size of the original material.

b. Proper Sanitation

A high-quality granulate is clean, with no fines or traces of dust. The absence of these elements shows that part of the material was lost during the air conveying process or filtration. Their removal is essential to keep the granulate clean and prevent any adverse effects on the subsequent machines like the moulding and extruder machines.

Also, the choice of material determines whether the granulate will have fines or not. Brittle or weak materials tend to break easily, contributing to fine formation.

c. Uniformity

It’s important to note that plastic granulators cannot be fed materials randomly. The material size must be right. Likewise, keeping the size of the granulate constant allows for a more consistent density and the feeding method.

The uniformity promotes proper mixing and blending of the granulates and the virgin pellets, making the level of melting within the barrel consistent.

2. What are the Tips for Selecting a Plastic Granulator?

There are two main tips to consider that is;

a. Identify Your Application/Purpose

Your application will guide you on the kind of granulator to get. In addition, factor in the size and materials that you will have in the process. The machine sizes vary; hence it is necessary to define the size you want clearly. However, there are chances you can get one that fits all materials, which would be very beneficial to you.

b. Check Out the Machine Parts

Ensure you confirm every part you wish to have is there. Among the essential components is the rotor, which can be opened or staggered. Consider the horsepower, shape and size of the chamber and the number of knives. All these parts contribute to the proper working of the granulator; thus, you can leave them out.


Granulators are detailed equipment with several parts that work together to facilitate the recycling of materials. They appear different based on the involved application, but their main aim is to produce granulates for reprocessing. Consider the tips given for proper selection to get a valuable machine that works for your needs and is worth the money spent.
