Lagging

Studded tile lagging is applied
to drive pulleys by Multotec.

Conveyor belt slippage, poor traction, poor wear properties, inadequate water shedding and resultant high running costs and lower productivity are the nightmares which plague operators of conveyors. Multotec’s direct bonded ceramic pulley lagging has become the widely accepted solution for mining and industrial operations as a cost effective response to these recurring problems.

“Multotec’s locally manufactured studded ceramic pulley lagging is particularly effective in aggressive conditions, even on bucket elevators or where material is inevitably trapped between the pulley shell and the conveyor belt,” Faan Viljoen, technical director of Multotec Wear Linings, says. “Ceramics have a significantly longer life compared with traditional rubber pulley lagging where material is removed from both the rubber lagging and the rubber belt bottom cover when belt slippage occurs. A further benefit of direct bonded ceramic lagging is a significant extension of the useful pulley life.

“We apply the studded tile lagging to drive pulleys, and smooth high density alumina ceramic tiles are used for nondrive pulleys,” he continues. “Traction is improved considerably, even under wet and slippery conditions. The insignificant ceramic wear rates will improve plant availability and reduce pulley and conveyor belt maintenance costs. While it is true that the ceramic material is slightly more costly than conventional rubber lagging, this is more than compensated for by its extended lifecycle of at least 20:1 compared to the usual expected life of rubber pulley lagging. This ultimately impacts very positively on the bottom line.”

The direct bonded ceramic lagging also reduces any danger of fire in instances where slippage continues and practically eliminates carcass and splice damage caused when the belt does grip.
