Conveyor Belt Fastener

Devices used to mechanically join the ends of a conveyor belt, forming a continuous loop. They provide a quick and often temporary or repairable alternative to vulcanized (spliced) joints.

Types of conveyor belt fastener  

Mechanical Fasteners:

Hinged Plate Fasteners: Two rows of plates joined by a hinge pin. Allows for easy installation and removal.

Solid Plate Fasteners: Non-hinged, typically bolted or riveted directly through the belt. Provides a strong, durable joint, often for heavier-duty applications.

Hook Fasteners: Series of hooks that penetrate the belt ends and are joined by a hinge pin. Common for lighter-duty belts.

Spiral Lace Fasteners: Made from a spiral of synthetic material or wire, joined by a pin. Very flexible.

Self-Setting Fasteners: Designed for quick, hammer-in installation.

Applications in Various Industries

Mining & Quarrying: Conveying coal, ore, aggregates.

Construction: Material handling (sand, gravel, cement).

Agriculture: Grain, feed, produce conveying.

Warehousing & Logistics: Package handling.

Food Processing: Conveying food products (with food-grade fasteners).

Cement Plants: Bulk material handling.

Technology:

Fastener Design: Engineered to distribute stress evenly across the belt width, minimize material spillage, and withstand tension and impact.

Installation Tools: Specific tools (belt punches, lacing machines, power tools) for efficient and correct installation.

Wear Resistance: Designs that minimize wear on the fastener and contact with idlers/pulleys.

Corrosion Resistance: For outdoor or wet environments.

Impact Resistance: For applications with heavy or sharp materials.

Food Grade & Non-Magnetic Options: For specific industries.

Material Selection Considerations

Metal Components:

• Steel: High-carbon steel, galvanized steel, stainless steel (304, 316) for plates, pins, and hooks. Selection depends on strength, corrosion resistance, and magnetic properties needed.
• Brass/Bronze: For non-sparking applications.

• Hinge Pins: Often hardened steel, stainless steel, or special alloys for wear resistance.
• Rubber/Polyurethane: For seals or cushioning elements in some designs.
• Coatings: Zinc plating, galvanizing, or specialized coatings for corrosion protection.
• Belt Material Compatibility: Fastener design and material must be compatible with the type of conveyor belt (rubber, PVC, synthetic).
