Mill application features. Frozen charge protection – Detects frozen charge in the mill, minimizing equipment wear and liner replacements. Coupling supervision – Detects if a failure or slippage occurs in the couplings and stops the system in case, preventing major damages. Stand still detection – Prevents the motors from re starting if the mill is still rocking or moving after a stop.
2 GEARLESS MILL DES The gearless mill drive eliminates ring gear, pinion, gearbox, coupling, motor shaft and motor bearings, used within a conventional mill drive system. By mounting the rotor poles directly onto the mill, the mill itself becomes the rotor of the gearless motor. Building a track record.
