Pelletizer Blades Overview

What Are Pelletizer Blades

Pelletizer blades are special tools used in machines to cut plastic into small pellets. These blades help turn plastic waste or new plastic into pellets for making new things. People in factories call these blades by many names, like:

• Granulator blades
• Pellet cutting knives
• Strand pelletizing knives
• Underwater pelletizing knives
• Water ring pelletizing knives
• Die-face cutter blades
• Air ring pelletizing knives
• Extrusion cutoff knives
• Facas rotativas
• Facas circulares

Each name shows a different job or machine type. Makers use strong materials like D2 steel, DC53, and carbide to make the blades last longer. Granulators need these blades to work well, so good quality blades help save money and keep machines running.

Como eles funcionam

Pelletizer blades work inside machines that make pellets. The blades cut plastic strands or pieces as they move through the machine. Most blades spin or move like scissors against another part. This cuts the plastic into even pellets.

The pelletizing process has a few steps:

1. Plastic goes into the machine and gets soft from heat or steam.
2. Rollers push the soft plastic through holes in a metal plate.
3. Pelletizer blades cut the plastic into pellets as it comes out.

Blade shape and space between blades are important. If the blades are spaced right, they cut cleanly and make even pellets. The process also depends on things like how thick the die is, how big the holes are, and how fast the blades spin. Heat and steam make the plastic soft, so the blades can cut it easily. This makes good pellets that can be used again or recycled.

Tip: Check and take care of pelletizer blades often. This keeps pellets good and helps blades last longer in machines.

Types and Materials

Tipos de lâmina

Pelletizer blades have many shapes and designs. Each blade type does a different job in making pellets. Factories pick the right blade for their machine and material.
