Premium Quality Diamond Pattern Conveyor Roller Cover Rubber Lagging Pulley

Key Purposes & Benefits:

1. Improved Traction/Belt Grip: Prevents belt slippage, especially in wet, muddy, or inclined conditions, ensuring consistent power transmission.

2. Reduced Wear: Acts as a sacrificial layer, protecting the expensive metal pulley from abrasion and prolonging its lifespan.

3. Self-Cleaning: Certain patterns help dislodge carried-over material (coal, ore, dust), preventing buildup and maintaining belt alignment.

4. Protects the Belt: Provides a cushioned interface, reducing wear on the belt’s underside.

5. Noise Reduction: Dampens operational noise compared to metal-on-metal contact.

Main Types of Lagging:

1. Diamond Groove Lagging:

Description: Features a raised diamond or rhombus pattern. The most common and versatile type.

Advantages: Excellent all-around performance. The grooves provide multiple gripping edges and effectively channel away water, dust, and fine materials.

2. Herringbone Groove Lagging:

Description: Characterized by a V-shaped or chevron pattern that points toward the center of the pulley.

Advantages: Superior self-cleaning and water dispersal. The directional pattern “wipes” the belt and pushes debris outward, preventing misalignment.

3. Plain (Smooth) Lagging:

Description: A smooth, non-patterned rubber surface.

Advantages: Easy to clean, provides uniform contact. Offers good grip in dry conditions.

4. Ceramic Lagging:

Description: Rubber sheets with embedded, wear-resistant ceramic tiles or hexagons.

Advantages: Offers the highest possible friction coefficient (significantly higher than rubber alone). Extremely durable and abrasion-resistant.

5. Polyurethane Lagging:

Description: Made from polyurethane, a polymer known for high abrasion and tear resistance.

Advantages: Excellent resistance to oils, chemicals, and ozone. Performs well in a wide temperature range.

Application Industries

• Mining, coal, ore handling
• Port terminals and shipping
• Cement, gravel, aggregate
• Power plants
• Grain, feed and fertilizer
• Chemical and salt industries
• Construction and sand & stone plants

Installation Methods:

Bonded/Spliced Lagging: Rubber sheets are chemically bonded (vulcanized) to the pulley surface in a workshop. This provides a seamless, permanent, and high-performance installation.

Slide-On/Mechanical Lagging: Pre-fabricated rubber sleeves are stretched or slid onto the pulley and secured with end rings. Allows for faster replacement in the field without removing the pulley shaft.

Strip Lagging: Individual rubber strips are bolted or glued onto the pulley. Useful for repair and maintenance in the field.

Selection Considerations:

Choosing the right lagging depends on:

Pulley Function: Drive, tail, bend, or snub pulley?

Environmental Conditions: Wet, dry, dusty, corrosive, extreme temperatures?

Belt Tension & Power Requirements: High-torque drives need higher friction lagging (e.g., ceramic).

Material Characteristics: Sticky, abrasive, oily?

Cost & Lifecycle: Balancing initial cost with maintenance frequency and total service life.
