Solid Waste Recycling, Decomposition, And Granulation Machine Blades

1.Primary crushing of large pieces of material: High strength alloy steel blades (such as Cr12MoV) are used to shear and tear large solid waste such as waste plastics and rubber. The material size is gradually reduced through a multi-level blade layout, which facilitates subsequent processing.

2.The flat blade design is suitable for rapid cutting of thin film plastics, while the corner blade is used for impact crushing of hard plastics such as ABS and PE.

3.Metal non-metal composite separation: Hard alloy welding blades (such as YG8) can cut metal components in tire steel cords or electronic waste, and work together with magnetic separation devices to achieve efficient separation of metal and non-metal.

4.Particle size control: The granulator blade dynamically adjusts the blade clearance (0.5-5mm) to further crush the decomposed fragments into uniform particles of 1-10mm, meeting the production needs of recycled plastic granulation or modified asphalt aggregate.

5.The surface coating of the blade (such as titanium nitride) can reduce plastic adhesion, ensure smooth particle surface, and meet the standard of flowability.

6.Preparation of high-purity materials: For electronic and electrical casings (such as PC/ABS alloy), all steel blades (HRC52-55) are used for fine crushing, and the particles separated from impurities can be directly used for injection molding or 3D printing consumables production.

7.Plastic recycling industry: Decompose blades to process waste plastic bottles, films, etc., and pelletize blades to generate 2-5mm particles for the production of recycled packaging materials or environmentally friendly building materials (such as plastic wood composite materials).

8.Electronic waste recycling: The multi axis shredder decomposes the circuit board casing, and the granulation blade separates plastic particles from metal powder, achieving a metal recycling rate of over 95%.

9.Tire resource utilization: During the decomposition stage, the tire steel wire layer is cut and the rubber blocks are broken. During the granulation stage, 8-40 mesh rubber powder is generated for use in rubber tracks, sound insulation materials, and other scenarios.

3.Selection Suggestions

Decomposition stage

Conventional materials (plastic/rubber): Cr12MoV alloy steel is preferred for its high cost-effectiveness.

Metal composites (such as tires): Hard alloy welding blades (YG8) achieve efficient cutting and metal separation.

High viscosity materials (hot melt adhesive/oil containing plastic): coated alloy steel (such as TiN coating) reduces adhesion and improves particle surface smoothness.

Fiber reinforced plastics (such as fiberglass): High speed steel materials (such as 6CrW2Si) have strong impact resistance and reduce the risk of blade breakage.

Summary: The decomposition blade is mainly made of high-strength alloy steel (Cr12MoV) and hard alloy (YG8) to cope with the impact of large materials and metal separation; The granulation blade achieves fine particle processing by coating alloy steel or high-speed steel, and the material selection of the two needs to match the material characteristics (hardness/viscosity/composition) and production requirements.
