We Have Solutions to Eliminate Slippage and Increase Belt Traction
Pulley lagging is the layer of material which is bonded to the shell of a conveyor pulley. The function of conveyor pulley lagging is to increase friction with the conveyor belt while protecting the shell from damage. Each type of pulley lagging has different variations, specifications and are used for a variety of purposes. Operating conditions, product abrasion, the type of pulley, the belt run speed and tension are important to know when selecting which type of pulley lagging to use as it is very dependent on the application and conveyor design.
Rubber is the most common type of pully lagging which offers good traction and is resilient to wear. Other functions include protection for the pulley shell and increased friction for conveyor belts. Rubber lagging is versatile and affordable and depending on your application, different properties such as thickness and hardness can be utilized to achieve your outcome.
Ceramic is often used in harsh conditions where abrasive material is conveyed because the ceramic is hardier and more durable than rubber lagging. Ceramic lagging can be applied to the pulley shell as a rubber backed ceramic sheet or strip. In this case, the rubber backing is bonded to the pulley shell. Alternatively, the ceramic tiles can also be bonded directly to the shell without a rubber sheet or strip.
The most common types of ceramic lagging are dimple and smooth finished ceramic. Both of these types of ceramic lagging offer a significant increase in friction and grip to the belt and can reduce belt slippage. Ceramic lagging has a greater service life because of its durability and it reduces lagging wear. The amount of coverage of ceramic on the surface of the lagging can be customized depending on the application. The amount of ceramic coverage can also increase or decrease the level of friction and grip.
Urethane has been gaining popularity in non-drive pulley applications where there are concerns about carryback buildup between the belt and lagging. It can be applied as a sheet or strip, either bonded with rubber-backed urethane or cast directly on the pulley shell. Compared to rubber lagging, it has a three to five times longer service life and provides higher abrasion resistance. The low coefficient of friction makes it the ideal solution for belts with premature wear.
