Lagging Problems

Elastotec Technology To Improve Performance

1. Debonding From Pulley

SOLUTION: Increased Adhesion To The Pulley Shell

Ceramic lagging has traditionally been applied to pulleys using two-part neoprene contact cements in a process generally known as ‘cold bonding’. Although this is a convenient system there are a number of limitations that can adversely impact the reliability and service life of the ceramic lagging…

2. Edge Lifting / Debonding

SOLUTION: Edge Sealing – Increased Adhesion To The Pulley Shell

A significant cause of ceramic lagging failure is lifting of the lagging edge due to corrosion occuring at the lagging pulley interface. This is more likely to occur in pulleys operating in wet environments and is mainly seen on Cold Vulcanised Ceramic Lagging applications…

3. Joint failure – Corrosion And Debonding

SOLUTION: Removal Of Joints – Increased Adhesion To The Pulley Shell

Cold Vulcanised lagging joints are a known weak point that allows water ingress and leads to corrosion of the pulley shell and eventually debonding of the lagging at this point. In wet conditions the rotation of the pulley under load generates a pumping action…

4. Tile Loss / Debonding

SOLUTION: Increased Tile To Rubber Adhesion Plus Bonds Resistant To Outdoor Ageing.

Elastotec has undertaken extensive outdoor testing of ceramic/rubber bond performance and has found that a number of primer/adhesive systems recommended by adhesive suppliers, provide a bond that initially offers rubber tear adhesion but, after prolonged exposure to moisture and UV, rapidly deteriorates…

5. Tile Breakage

SOLUTION: Lagging Design With Built In Cushioning Plus High Performance Ceramic

The unique design of Elastotec Hot Vulcanised Ceramic Lagging (HVCL) and Cold Vulcanised Ceramic Lagging (CVCL) ensures that tiles are bonded with rubber on both sides and back, providing a more reliable layer of protection from impact and significantly reducing the risk of tile cracking…

6. Edge Wear

SOLUTION: Lagging Design Engineered To Provide Ceramic Coverage Across Full Pulley Face Width

Ceramic lagging availabe in a range of roll sizes including 6.5 m,10 m and 50 m. 10 mm rubber between each row of tiles to allow for strips to be cut to a range of pulley face widths for full width ceramic lagging with minimal wastage…

7. Belt Cover Wear

SOLUTION: Lagging Design Engineered To Allow Ceramic Tiles To Move Under Load And Minimise Slippage / Belt Cover Wear

Belt Cover wear occurs when there is slippage between the lagging and the conveyor belt. When ceramic drive lagging is used and there is slippage the wear occurs in the rubber belt cover as this is the softer less abrasion resistant surface…
