As a supplier of Belt Conveyor Drums, I often encounter inquiries about the types of lagging available for these crucial components. Belt conveyor drums play a vital role in the smooth operation of conveyor systems, and the right lagging can significantly enhance their performance, durability, and efficiency. In this blog post, I'll explore the various types of lagging options that are commonly used for belt conveyor drums and discuss their benefits and applications.
Rubber Lagging
Rubber lagging is one of the most popular choices for belt conveyor drums. It offers excellent traction, which helps prevent belt slippage, especially in wet or dirty environments. The rubber material provides a high coefficient of friction between the drum and the conveyor belt, ensuring efficient power transmission.
There are different grades of rubber lagging available, each with its own unique properties. For example, smooth rubber lagging is suitable for general-purpose applications where a moderate level of traction is required. It is easy to clean and maintain, making it a cost - effective option for many industries.
On the other hand, patterned rubber lagging, such as chevron or herringbone patterns, provides even better traction. The patterns help to channel water, dirt, and debris away from the contact area between the drum and the belt, reducing the risk of slippage. Patterned rubber lagging is commonly used in applications where the conveyor operates in wet conditions, such as mining, quarrying, and wastewater treatment plants.
Another advantage of rubber lagging is its ability to absorb shock and vibration. This helps to protect the conveyor belt and other components from damage, extending their service life. Rubber lagging also provides a cushioning effect, which can reduce noise levels during operation, creating a more comfortable working environment.

Ceramic Lagging
Ceramic lagging is a high - performance option that is designed for demanding applications. It consists of ceramic tiles or inserts that are bonded to the surface of the drum. Ceramic lagging offers several key benefits, including extreme wear resistance, high heat resistance, and excellent traction.
The ceramic material used in lagging is extremely hard and can withstand abrasive materials, such as coal, ore, and gravel, without significant wear. This makes ceramic lagging ideal for applications in the mining, cement, and steel industries, where the conveyor belts are exposed to harsh and abrasive conditions.
In addition to its wear resistance, ceramic lagging also has a high coefficient of friction, which provides excellent traction even in wet or dirty environments. The ceramic tiles are often designed with a special pattern or texture to enhance the grip on the conveyor belt.
Ceramic lagging can also withstand high temperatures, making it suitable for applications where the conveyor operates in hot environments, such as kilns or furnaces. The high heat resistance of ceramic lagging helps to prevent the degradation of the lagging material and ensures consistent performance over time.

PU (Polyurethane) Lagging
Polyurethane (PU) lagging is another option that offers a combination of good traction, wear resistance, and flexibility. PU lagging is made from a synthetic polymer that has excellent mechanical properties.
One of the main advantages of PU lagging is its high abrasion resistance. It can withstand the wear and tear caused by the movement of the conveyor belt and the materials being transported. This makes it a suitable choice for applications where the conveyor operates in abrasive environments, such as recycling plants or sand and gravel operations.
PU lagging also has good chemical resistance, which means it can resist the effects of various chemicals and solvents. This makes it suitable for applications in the chemical and pharmaceutical industries, where the conveyor belts may come into contact with corrosive substances.
In addition, PU lagging is relatively lightweight and flexible, which can reduce the overall weight of the conveyor drum and make it easier to install and maintain. It also provides a good level of traction, helping to prevent belt slippage. Our Conveyor Head Pulley can be equipped with high - quality PU lagging for optimal performance.
Selection Considerations
When choosing the right type of lagging for your belt conveyor drums, several factors need to be considered.
- Operating Environment: The environmental conditions in which the conveyor operates are crucial. If the conveyor is exposed to wet or dirty conditions, rubber or ceramic lagging may be a better choice due to their high traction and resistance to water and debris. In abrasive environments, ceramic or PU lagging may be more suitable because of their wear - resistant properties.
- Belt Type and Load: The type of conveyor belt and the load it carries also affect the lagging selection. Different belts have different surface characteristics, and the lagging should be chosen to provide the best match for optimal traction. Heavier loads may require a lagging material with a higher coefficient of friction to prevent slippage.
- Cost and Maintenance: Cost is always a consideration. Rubber lagging is generally more cost - effective than ceramic or PU lagging. However, the long - term maintenance costs should also be taken into account. For example, ceramic lagging may have a higher upfront cost but lower maintenance requirements due to its high wear resistance.
Conclusion
Selecting the appropriate lagging for belt conveyor drums is essential for ensuring the efficient and reliable operation of conveyor systems. Rubber lagging is a versatile and cost - effective option for general - purpose applications, while ceramic lagging offers superior wear and heat resistance for demanding environments. PU lagging provides a good balance of abrasion resistance, chemical resistance, and flexibility.
