How to Select Plastic Granulators? 4 Steps

Investing in a plastic granulator is a significant decision. Choosing the right granulator is crucial because selecting one that is too large can lead to unnecessary expenses, while one that is too small may not meet your operational needs. Therefore, understanding the right granulator for applications such as injection molding, blow molding, extrusion, or recycling is essential. Below are four important steps to consider when selecting plastic granulators.

One of the first factors to evaluate is the speed of the granulator. Depending on the quantity of materials you need to cut, you can choose between a low-speed granulator or a centralized granulator.

• Step 1: Determine the Type of Granulator Required

The initial step is to ascertain the type of granulator you require. Low-speed granulators are typically suited for materials that necessitate minimal cutting, whereas centralized granulators cater to those that require extensive cutting.

• Step 2: Assess the Size of Materials to Be Crushed

Next, consider the dimensions of the materials you intend to crush along with the inlet diameter of the granulator. The maximum size of the materials should not exceed the diameter of the granulator's inlet to function effectively.

• Step 3: Evaluate Material Thickness and Hardness

The thickness and hardness of materials are critical factors that will impact the type of power needed during the granulation process. This assessment is key in determining which granulator is suitable for your requirements.

• Step 4: Consider the Required Particle Size

Finally, it’s important to determine the desired particle size, as this will help you choose the specific model of the granulator and decide on the appropriate size of the screen needed.

To enhance your shredder or recycling processes, thoroughly evaluate the options. If you plan to recycle plastics or rubbers, you might want to consider two practical options:

• Single-Shaft Shredders are ideal for thick, rigid materials that need shredding. For instance, the SGS-S series effectively handles large tubes and solid pieces, making them suitable for rubber and wood recycling.
• If you require something more versatile, consider a film granulator. These machines are specifically designed for processing various kinds of leftover plastics, like packaging braids, extruded sheets, and films with thicknesses ranging from 0.5mm to 4mm.
