Designed for endurance
The rotors are made up of closely spaced blades in Hardox® 500 wear plate with a thickness between 6 and 25 mm (0.236” and 0.984”). The blades are welded to a Hardox® 500 Tube, which is connected to the drive system.
“Since there is a lot of welding involved and to optimize the process, we talked with SSAB’s technical support. The recommendation was to use stainless steel wire for our MAG welding equipment to avoid preheating of the steel. This has worked fine,” says Jussi Saari, Engineer at Remu.
Initially, Remu used hardfaced tubes in S355 steel. This solution was not satisfactory, it took a longer time to produce and did not offer the required service life. By switching to Hardox® 500 Tube, not only could Remu reduce the thickness of the tubes to save weight, but the extended service life lived up to Remu’s high expectations.
Screening buckets are used for many different applications, such as producing padding material on site to protect gas and oil pipes, producing topsoil, mixing and aerating contaminated soil, breaking down coal into smaller pieces and screening demolition waste, drywall and glass. Particles of the desired size will pass through the screens, while oversized material remains in the bucket.
Remu’s screening buckets can be installed on all types of excavators with a customized adapter. Hydraulic hoses are connected to the excavator’s hydraulic system to drive the rotor motors.
