Cr6W2Ssi Granulator Blade Hard Plastic PVC Powder Pelletizing Line
Description:
Here is a detailed overview of the key information about granulator blades:
1,Blade Material:
- High-Carbon Steel: A common and cost-effective blade material that provides good toughness and edge retention.
- Alloy Steel: Blades made from alloy steels like chromium or manganese-based alloys offer enhanced hardness and wear resistance.
- Carbide-Tipped: The hardest and most durable option, carbide-tipped granulator blades maintain their sharp edge for extended periods.
2,Blade Geometry:
- Cutting Edge Angle: The angle of the blade's cutting edge, typically between 25-35 degrees, optimized for efficient cutting.
- Bevel: The angled surface on the back of the blade that creates the sharp cutting edge.
- Serrated Edge: Some granulator blades feature a serrated edge design to improve the cutting action.
3,Blade Dimensions:
- Length: Ranges from around 6 inches up to 24 inches or more, depending on the granulator size.
- Width: Typically 1 to 4 inches, based on the granulator's capacity and application.
- Thickness: Generally between 1/8 to 1/2 inch thick, providing the necessary rigidity.
- Bore/Arbor Size: The diameter of the hole that allows the blade to be mounted on the granulator's rotor.
4,Blade Quantity:
- Most granulators use multiple blades (2, 4, 6, or more) per rotor assembly.
- The number of blades affects the size reduction rate and granule consistency.
5,Blade Sharpening and Replacement:
- Granulator blades can typically be resharpened multiple times to extend their usable life.
- However, severely worn or damaged blades will need to be replaced to maintain optimal performance.
6,Blade Mounting and Clearance:
- Precise installation and proper clearance between the blades and the granulator's housing are critical for safe and efficient operation.
- Incorrect mounting or excessive blade-to-housing clearance can lead to poor cutting, increased power consumption, and potential safety hazards.

Here are the key characteristics of the main materials used for granulator blades:
1,High-Carbon Steel:
- Composition: High-carbon steel typically contains 0.6-1.0% carbon content, along with small amounts of other alloying elements like manganese, chromium, or vanadium.
- Hardness: High-carbon steel blades have a Rockwell hardness range of around 50-60 HRC, providing good edge retention.
- Toughness: The higher carbon content makes these blades relatively tough and resistant to chipping or breaking.
- Cost: High-carbon steel is a cost-effective material option for granulator blades.
2,Alloy Steel:
- Composition: Alloy steel blades contain additional alloying elements like chromium, manganese, or molybdenum to enhance specific properties.
- Hardness: Alloy steel blades can achieve higher Rockwell hardness, often in the range of 55-65 HRC, for improved wear resistance.
- Wear Resistance: The alloying elements give alloy steel blades superior abrasion and wear resistance compared to high-carbon steel.
- Toughness: Alloy steel blades generally maintain good toughness and impact resistance.
- Cost: Alloy steel blades are more expensive than high-carbon steel but offer enhanced performance.
3,Carbide-Tipped:
- Composition: Carbide-tipped blades have a tungsten carbide cutting edge brazed or welded onto a steel body.
- Hardness: Carbide tips have an extremely high Rockwell hardness, typically between 80-90 HRC, providing exceptional wear resistance.
- Edge Retention: Carbide-tipped blades can maintain their sharp cutting edge for significantly longer than high-carbon or alloy steel blades.
- Brittleness: While very hard, carbide tips are more brittle and susceptible to chipping or cracking than steel blades.
- Cost: Carbide-tipped granulator blades are the most expensive option due to the specialized manufacturing process.
