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

TECHNICAL AND COMMERCIAL BENEFITS OF GEARLESS

2021-2-17  Motor The GMD is a drive system without any gear where the transmission of the torque between the motor and the mill is done through the magnetic field in the air gap between the motor stator and the motor rotor. The concept to drive the mill this way is relatively simple using the mill body as motor rotor and mounting the poles there.

What is an inching drive? Motion Control Tips

An inching drive is used as an auxiliary system to the main drive for a large machine such as a ball mill, industrial kiln, conveyor, or elevator. Its purpose is to turn the equipment at a speed slower than the normal operating speed — typically 1 to 2 rpm, although fractional rpms are also common — and to do so at high torque — typically

CNC Drive Components: Stepper Motors, Servo

The drive components are the mechanical components that "drive" the CNC machine along its axis. The most common components associated with a drive system, are the motors, lead or ball screw, or rack and pinions. The whole idea of a drive system is to convert controlled rotary motion to controlled linear motion with the help of a CNC Controller
