SOLUTIONS FOR ROLLER PRESSES
Wear life of the rollers can be significantly increased with Welding Alloys’ specially developed Roller Press solution called RPMaxLife. This technology greatly reduces the risk of fatigue cracking in the substrate layers through its shock resistant design, eliminating the need for intermediate roller repairs. Its proven design can resist roll surface damage even when faced with tramp metal such as ball mill media, without spalling or surface fracture.
RPMaxLife is offered as a complete solution by our Integra™ Service Centres and refurbishment can be carried out in our workshops or in situ, depending on the circumstances and customer requirements. Welding Alloys is able to refurbish rollers according to the customer’s own drawings or original OEM designs. It is also possible to include additional services within our maintenance package, including surface wear monitoring, or the application of chevrons and other surface pattern geometries, for increased efficiency of the grinding process.
RPMaxLife significantly reduces downtime and total cost of ownership while simultaneously increasing mill throughput. Our data shows that increased wear life of up to 100% or more can be achieved and while we guarantee a minimum of 6000 hours, customers have recorded examples 12,000+ hours in practice. The welded layers of traditional consumables are typically not capable of withstanding localised impact caused by foreign material, however with the RPMaxLife solution, the risk of roll damage is significantly reduced.
