CRUSHERS 82 E&MJ • JUNE 2019 be a little bit of an oil mist and you will see there will be a brass cap missing," Klein said. "It will be very obvious that it is the SafeSet, and then you can reset it really quickly." As part of the reset, "you have to re-pressurize it," he said. "You can have these reset in 10 minutes, once they are down." That's nothing compared to the downtime resulting from a damaged motor or drive. "With breakage, you could be down for a whole shift," Klein said. For use with a crusher, the torque threshold setting on a SafeSet coupling is constant for the life of the coupling. "Safe- Set will not fatigue at all," Klein said, and thus "will not give a false release." Company literature stated the coupling is rated for up to 20,000 kiloNewton-meters and can be confi gured for pro- cess-specifi c requirements. A similar solution that would be advantageous for certain crushing systems is Voith's SlipSet TLC. For a system processing ore replete with tramp materials, SlipSet can act as a shock absorber for short-duration torque overloads. Instead of releasing, the coupling slips temporarily, allowing the system to clear blockages. It ensures continuous production, the company reported. The torque threshold can be set to the needs of the crusher system. When required, SlipSet can slip continuously until the drive is stopped and the jam rectifi ed.
