The following is a professional guide to selecting a shredder for fiberglass reinforced plastic (FRP) materials, combining its high hardness, strong abrasiveness and composite structural characteristics to provide a precise selection program:
I. Core pain points of FRP processing
Material Characteristics:
FRP = fiberglass (high hardness) + resin (viscous), extremely abrasive to the blade, easy to lead to ordinary equipment, “blunt knife, overheating, efficiency plummet”.
May contain metal inserts (e.g., bolts), coatings and other impurities, requiring equipment to be extremely impact resistant.
Environmental requirements:
Crushing fiberglass dust (hazardous to the respiratory system), the need for sealed dust removal design.
Second, glass fiber reinforced plastic shredder to buy 6 key points
1. Blade material and structure
Material:
Must choose tungsten carbide alloy (WC-Co) or ceramic coated blade, hardness ≥ HRC60, wear resistance than ordinary tool steel to enhance more than 3 times.
Avoid ordinary manganese steel blades (easy to collapse, less than 200 hours of life).
Structure:
Twin-shaft shredder type (low speed and high torque): suitable for large glass and steel plates/tubes with uniform pieces.
Four-shaft shredder: contains pre-shredding + fine shredding dual-stage design, more efficient in handling mixed waste with impurities.
2. Power and torque
Motor power:
Higher power is needed for processing fiberglass, more than 55kW is recommended (e.g. processing capacity of 1t/h corresponds to 55-75kW).
Equipped with hydraulic drive system, it can automatically reverse to prevent jamming and protect the motor.
3. Dust control and sealing design
Dust control:
Fully enclosed structure + negative pressure dust removal interface (recommended Φ300mm or above piping), with cyclone dust collector or bag dust collector, to ensure the dust concentration <5mg/m³.
Spraying dust-reducing device is installed at the discharge port (optional).
Anti-fiber splash:
The observation window adopts explosion-proof glass, and the door seam is sealed with silicone sealing strip.
4. Anti-wear structure
Body lining:
Manganese steel liner (thickness ≥15mm) is added to the contact surface to reduce the wear of the box body.
Bearings and gears:
SKF/FAG heavy-duty bearings are adopted, and the lubrication system supports continuous working temperature ≤80℃. High-quality alloy blade single service life should be ≥ 800 hours, replacement cost <0.5 yuan/kg (ordinary blade cost > 1 yuan/kg).
Energy consumption ratio:
The electricity consumption per ton of standardized equipment should be <40kWh (inferior equipment may be >70kWh).
Third, the brand reference
Brands:
SOYU Machinery: four-shaft model is suitable for high abrasion scenarios, with mature dust control technology.
Provide customized FRP production line, cost-effective (price 50% lower than imports).
Selection of fiberglass shredder need to follow the “wear-resistant priority, sealing must be selected, torque is the king” principle, combined with the scale of treatment and back-end use, select the specialized, modular equipment, to avoid frequent maintenance downtime due to saving a small amount of money!
