In ore processing, there are wet areas or processes involving acids, water and other liquids that cause the material to adhere to the surface of the roller. The adhering material forms a layer of crust or shavings that hinders the movement of the conveyor belt, resulting in misalignment, increased energy consumption and a substantial reduction in the service life of the roller.

At ULMA Conveyors Components we have developed different types of coatings with special shapes that reduce the adherence of the material on the belt and increase the service life of the roller by 50%.

ULMA offers a wide range of rollers designed for standard operating conditions as well as for more demanding environments. All of them are manufactured using high-quality components and rigorous manufacturing processes, incorporating our own sealing systems that ensure effective sealing, optimal bearing protection, and reliable, long-lasting operation in any application.
