Introduction: Ceramic Pulley Lagging Installation is a crucial process used across various industries to enhance the performance and longevity of conveyor systems. This article provides a comprehensive guide on the step-by-step procedure for applying Ceramic Pulley Lagging Installation, emphasizing the importance of precision and safety in this critical operation.

  1. Disconnect the conveyor’s power supply and hang safety warning signs. Assess the condition of residual adhesive on the drum’s surface to determine if it needs to be removed. Check if the drum can be manually rotated and, if necessary, disconnect the connecting pin. If the area covered by residual adhesive exceeds 0.5m², use an adhesive removal machine to eliminate it; otherwise, there’s no need to remove it.
  2. Grind the drum’s surface to remove dirt, grease, and other substances that hinder adhesive bonding. Use mechanical, physical, and chemical methods to increase the drum’s surface roughness, thereby enhancing the adhesive’s wetting ability. Ensure safety by wearing protective eyewear and masks.
  3. Clean the drum surface to remove dirt, dust, grease, etc., to ensure the adhesive’s wetting. Use a high-quality cleaning agent and make sure the surface is thoroughly cleaned. Allow time for drying.
  4. Apply a transition treatment by evenly coating the drum’s surface with a metal primer. Allow it to dry completely to prevent surface contamination, extend the metal’s storage period, improve adhesive wetting, and enhance adhesive bonding strength.
  5. Apply the adhesive by mixing and stirring the cold vulcanizing adhesive and hardener. Apply it evenly to the metal surface of the drum, ensuring it dries completely, typically in 15-45 minutes. Multiple paint of adhesives can be applied.
  6. Affix the ceramic pulley lagging by establishing a bonding reference line. Cover the semi-cured surface of the ceramic pulley lagging with plastic film, align it with the reference line on the drum, and attach it while pressing it firmly. Ensure the edges match the reference line. Our ceramic pulley lagging contains 20mm x 20mm alumina ceramic tiles embedded in specialized rubber. This design increases the friction coefficient on the drum’s surface, reducing the likelihood of conveyor belt slippage, featuring a semi-vulcanized bonding layer, the ceramic pulley lagging bonding surface doesn’t need to grind before use, and it can bond with cold vulcanizing cement directly.
  7. Seal the seams by cutting a V-shaped groove at the outer edge. Use a steel wire brush to grind the groove, then clean off any dust. Mix components A and B of the adhesive at a 1:1 ratio and apply the first coat at a 45° angle to the seam. Allow it to dry completely until it is no longer sticky to the touch. Apply a second coat of the mixed adhesive. Preheat the adhesive gun and use it to fill the seam while compacting with a roller.

Important Notes:

Environmental Conditions: Ensure the temperature is above 10°C, relative humidity is below 90%, there is no rainwater, and the work area is dust-free.

Grinding and Cleaning: Thoroughly clean the surface, removing any residual adhesive, rust spots, dents, or jagged edges.

Metal Treatment and Primer: Apply them evenly, allowing them to dry completely. If they do not dry, use methods such as hot air blowers and drying.

Adhesive Application: Apply multiple coats evenly, allowing each coat to dry before applying the next.

Lining: When the ceramic pulley lagging and the drum bonds, use rolling and tapping techniques from the center toward the edges to prevent air bubbles.

Sealing: Ensure there are no gaps, overlaps, or air bubbles.

Curing: It’s best to allow the lining to cure for 8 to 24 hours after ceramic pulley lagging and drum bonding for optimal results.
