2019-3-11 · The wheel speed, in terms of peripheral speed, is commonly in the range of 5,500 to 6,500 fpm (about 30 to 35 m/sec). High-speed grinding, operating at about twice that speed, is used on specially built surface grinding machines only, which are designed generally for abrasive machining and require appropriately manufactured grinding wheels.

Cardan shafts connect the main drive motors to the high-speed reducer shafts via torque-limiting couplings. These torque limiters are manually-engaged and critical for protecting the drive and HPGR components in the event of an overload situation. Rigid drive couplings attach the reducer output shafts to the roll shafts completing the drive system.
