Product Specification

Tungsten Carbide Pelletizer Cutting Blade For Plastic Shredder Machine

Description:

Some key factors related to the size and dimensions of pelletizer blades include:

1,Blade Diameter:

• The blade diameter is typically determined by the size of the pelletizer chamber and the desired pellet size.
• Common pelletizer blade diameters range from around 6 inches (150 mm) to 30 inches (750 mm) or more, depending on the scale of the equipment.

2,Blade Thickness:

• The blade thickness is influenced by the required strength, rigidity, and wear resistance of the blades.
• Typical blade thicknesses range from 1/8 inch (3 mm) to 1/2 inch (12 mm) or more, depending on the application.

3,Blade Length:

• The blade length is determined by the pelletizer chamber size and the desired coverage area for the material being processed.
• Blade lengths can range from a few inches (50-100 mm) up to 20 inches (500 mm) or more for large-scale industrial pelletizers.

4,Cutting Edge Angle:

• The angle of the blade's cutting edge is crucial for efficient material cutting and shaping.
• Typical cutting edge angles range from 15 to 30 degrees, with the specific angle optimized for the material being processed.

5,Number of Blades:

• The number of blades installed in a pelletizer can vary, typically ranging from 4 to 12 blades or more, depending on the pelletizer size and design.

6,Blade Material:

• The blade material is selected based on factors like hardness, wear resistance, and corrosion resistance required for the specific application.
• Common blade materials include tool steel, tungsten carbide, ceramic composites, and specialized alloys.

Pelletizer Blades Specifications:

The blade specifications for pelletizers used in the plastics industry versus the biomass industry can differ in the following ways:

Plastics Industry:

1,Blade Diameter and Length:

• Plastic pelletizer blades tend to be larger in diameter, often ranging from 12 to 24 inches (300 to 600 mm), to handle the higher throughput required for plastic materials.
• The blade length is also typically longer, around 10 to 16 inches (250 to 400 mm), to provide better coverage and cutting performance.

2,Blade Thickness:

• Plastic pelletizer blades are often thicker, around 1/4 to 1/2 inch (6 to 12 mm), to provide the necessary strength and rigidity to withstand the higher processing forces involved.

3,Cutting Edge Angle:

• The cutting edge angle for plastic pelletizer blades is typically steeper, around 20 to 30 degrees, to ensure efficient cutting and shearing of the tough plastic materials.

4,Blade Material:

• Plastic pelletizer blades often use specialized tool steels or tungsten carbide to provide high hardness, wear resistance, and edge retention required for the abrasive nature of plastic materials.

Biomass Industry:

1,Blade Diameter and Length:

• Biomass pelletizer blades tend to be smaller in diameter, typically ranging from 6 to 12 inches (150 to 300 mm), as the throughput requirements are generally lower compared to plastics.
• The blade length is also shorter, around 6 to 10 inches (150 to 250 mm), as the biomass materials are less dense and require less cutting force.

2,Blade Thickness:

• Biomass pelletizer blades are often thinner, around 1/8 to 1/4 inch (3 to 6 mm), as the processing forces are lower compared to plastics.

3,Cutting Edge Angle:

• The cutting edge angle for biomass pelletizer blades is typically shallower, around 15 to 20 degrees, to provide a more gentle cutting action suitable for the fibrous and less abrasive nature of biomass materials.

4,Blade Material:

• Biomass pelletizer blades may use a wider range of materials, including tool steels, specialized alloys, and even ceramic composites, depending on the specific biomass feedstock and its abrasiveness.
