Materials suitable for waste wind turbine blade shredders:

The waste shredder machine can shred nearly all common industrial waste. Typical suitable materials include:

1. Waste wind turbine blades (fiberglass reinforced epoxy resin material, including balsa wood/PVC foam core material and metal embedded parts);

2. Various large fiberglass components: fiberglass hulls, fiberglass pipes, fiberglass storage tanks, FRP profiles, fiberglass gratings;

3. Fiberglass sandwich composite panels, resin-based composite material components.

Waste Wind Turbine Blade Crushing and Separation Line:

The waste wind turbine blade recycling line employs a mechanical-physical method, without altering the chemical composition of the materials. Crushing and separation are achieved through mechanical force and differences in material properties:

1. Crushing Principle: A combination of low-speed, high-torque shearing and shredding combined with high-speed impact crushing is used. The dual-shaft shredder uses blades to shear and tear, breaking down the toughness of fiberglass; the fine crusher uses impact, compression, and grinding to break the bonding interface between the resin matrix and fiberglass, separating large pieces of material into particles.

2. Separation Principle:

- Magnetic Separation: Magnetic force adsorbs internal metal parts such as lightning protection metal and bolts from the blades;

- Vibrating Screening: Gradually classifies by particle size;

- Airflow Classification (Gravity Separation): Lightweight balsa wood floats, while high-density fiberglass/resin particles sink, separating the core material from the fiberglass;

- Fine Airflow Classification: Further separates resin powder from fiberglass flocs.

3. Environmental Protection Facilities: The entire line uses a closed negative pressure dust collection system, with pulse dust collectors to collect ultrafine dust and control dust leakage.

FINAL PRODUCT

Discharge particle size can be customized.

Core Advantages

1. 1. High torque and strong shearing, suitable for the high toughness and non-breakable characteristics of fiberglass and epoxy fiberglass, reducing the risk of jamming and material blockage;

2. Cutters are made of wear-resistant hard alloy, resistant to fiberglass wear, resulting in a longer service life;

3. Low-speed operation, low impact, low noise, and less dust generation than high-speed crushers;

4. Controllable output particle size, producing blocky materials, suitable for downstream fine crushing and air classification processes;

5. Can directly feed 3-6m segmented wind turbine blades, large feed size, suitable for on-site pretreatment conditions;

Equipped with overload protection and reverse function, automatically reverses when encountering hard metal objects that jam, protecting the spindle and cutters;

6. The entire machine can be fitted with a sealed housing for easy connection to a negative pressure dust collection system, meeting environmental protection requirements.
