Pulley lagging
Pulley Lagging: protecting the pulley shell from wear damage, and extending the pulley’s service life. The lagging also increases the friction between the conveyor belt and the pulley to reduce belt slippage and minimizes the buildup of bulk material, water, ice, or snow.
Available Lagging： Plain, Diamond, Square, Ceramic, Slide lagging, etc.
Diamond Pulley Lagging (Do-lag)
Without CN bonding layer (Do-Lag)
Mini Diamond (M Do-Lag)
| Tensile Strength (MPa) | Elongation at break (%) | Density (g/cc) | Hardness (Shore A) | Thickness (mm) | Width (mm) |
| 7 | 350 | 1.3 | 65+/-5 | 8~30 | up to 1400mm |
| 5 | 300 | 1.45 | 65+/-5 | 8~30 | up to 1400mm |
Large Diamond (L Do-Lag)
| Tensile Strength (MPa) | Elongation at break (%) | Density (g/cc) | Hardness (Shore A) | Thickness (mm) | Width (mm) |
| 8 | 350 | 1.35 | 65+/-5 | 10~30 | up to 2000mm |
With CN bonding layer (Do-Lag Plus)
Mini Diamond (M Do-Lag Plus-1)
| Tensile Strength (MPa) | Elongation at break (%) | Density (g/cc) | Hardness (Shore A) | Thickness (mm) | Width (mm) |
| 12 | 400 | 1.2 | 65+/-5 | 8~30 | up to 1400mm |

| 15 | 450 | 1.15 | 60+/-5 | 8~15 | 2000mm |
| Specification (mm) | Pattern | Dimension (mm) |
| 8x2000x10000 | square | 20×20 |
| 10x2000x10000 | square | 20×20 |
| 12x2000x10000 | maxi diamond | 85×50 |
| 15x2000x10000 | maxi diamond | 85×50 |
Crowned Diamond (C Do-Lag Plus)
| Tensile Strength (MPa) | Elongation at break (%) | Density (g/cc) | Hardness (Shore A) | Thickness (mm) | Width (mm) |
| 12 | 400 | 1.35 | 65+/-5 | 10/12/15 | 250/500 |
Ceramic Pulley Lagging (Ce-Lag plus)
Ceramic pulley lagging is especially suited for pulleys where slippage and excessive wear and tear problems make normal rubber lagging ineffective. The alumina ceramic tiles help in the proper grip of the belt under wet, muddy, or any other such arduous conditions.
| Tensile Strength (MPa) | Elongation at break (%) | Density (g/cc) | Hardness (Shore A) | Abrasion loss (mm3) | Content of aluminum oxide (%) |
| 17 | 400 | 1.2 | 65+/-5 | 120 | 92% |
| Width (mm) | Thickness (mm) | Length (m) |
| 215 | 12 | 10m |
| 250/300/400/500 | 12/15/20 | As per request |
Slide Rubber Lagging
Slide rubber lagging is suitable for coal, mining, port, and other application environment or the conveyor system, where has a problem of belt slippage.
The high wear-resistant rubber improves the abrasion resistance and oxidation resistance of rubber greatly, prolonging service life outdoors. The diamond pattern and groove greatly increase friction between the belt and pulley, preventing the belt from slipping. This is easy for installation and replacement as well.
