One of the most popular forms of lagging used on conveyor pulleys is ceramic pulley lagging. Because ceramic is harder and more durable than rubber lagging, it is frequently utilised in difficult environments where abrasive material must be transported.
As a rubber-backed ceramic sheet or strip, ceramic pulley lagging can be placed to the pulley shell. The rubber backing is attached to the pulley shell in this case. Ceramic tiles can also be glued directly to the shell without the use of a rubber sheet or strip.
Ceramic Lagging: Common Types:
Dimple and smooth finished ceramic pulley lagging are the most prevalent varieties of ceramic pulley lagging. Both varieties of ceramic lagging provide a significant improvement in belt friction and grip, as well as the ability to prevent belt slippage.
Smooth Ceramic Lagging vs. Dimple Ceramic Pulley Lagging:
Dimpled ceramic pulley lagging is commonly used on drive pulleys because it increases friction and grip, making it easier to drive the conveyor belt. Smooth ceramic can be used to lag non-drive pulleys, but this is less usual.
Smooth ceramic pulley lagging is typically used on non-drive pulleys because it reduces the requirement for friction, which can cause additional belt wear. When undesirable friction and slippage occurs, the use of dimple ceramic pulley lagging on non-drive pulleys has a high risk of scratching and damage to the belt.
Advantages in general
Because of its resilience, ceramic pulley lagging has a longer service life and lowers lagging wear. Depending on the application, the degree of ceramic covering on the lagging surface can be varied. The amount of ceramic covering can also affect how much friction and grip there is.
Kolag Ceramic Pulley Lagging:
At DYNA Engineering, we provide a variety of rubber-backed ceramic lagging alternatives, including Kolag ceramic pulley lagging. Ceramic tiles with a dimple contour are inserted in rubber strips to create this design.
Design Features and Benefits:
Belt Slippage is Reduced with a Dimple Profile:
The dimple profile of the ceramic tiles on the Kolag ceramic pulley lagging greatly reduces slippage between the belt and the drive pulley. The rough ceramic face produces up to two times greater coefficient of friction than rubber lagging, which reduces slippage.
The Kolag ceramic pulley lagging is especially useful in wet or muddy conditions where slippage is more of an issue due to the dimple profile’s reduction in belt slippage.
Furthermore, dimple ceramic pulley lagging’s reduction in belt slippage can lead to longer conveyor belt life, as constant belt slippage, regardless of lagging type, causes wear on the belt.
Resistant to Wear
The general benefit of ceramic pulley lagging, which is better wear resistance, is present in Kolag ceramic lagging. Ceramic pulley lagging’s wear-resistant construction implies it will survive longer in hostile environments before needing to be replaced.
Rubber Lagging with Embossed Design:
The “arrow-boss” design, which is an embossed rubber lagging design, is one of Kolag ceramic lagging’s unique design elements. This design element maximises water shedding benefits and outperforms standard rubber lagging in this regard.
Kolag ceramic pulley lagging has a buffed finish or optional bonding layer that allows it to be cold bonded on site, in addition to reduced belt slippage, improved water shedding, and wear resistance.
