Gearless mill drives. Longer service intervals thanks to low-wear drive processes SIMINE Gearless mill drives’ rpms can be tailored to your operations at any time, and are infinitely variable and uncomplicated. Whether manually or fully automatic rpms can be adjusted to account for the proper-ties of the ore, resulting in significantly lessA Mechatronic Solution Design and Experience with Large,low starting current no contribution to short circuit current no mechanical connection between motor and mill clock and counterclockwise rotation of the mill The main area of application of gearless drives is the high power low speed range, where an extremely smooth operation, also at minimum speed is required combined
That is why the gearless drive of a grinding mill is one of the most crucial pieces of equipment in the concentrator and why it is subject to particularly high demands. Siemens has provided about 80 SIMINE Gearless mill drives to the mining industry since 1980. In these thirty-plus years, SIMINE Gearless mill drives have accumulated a combinedGearless mill drives Grinding ABB,Our GMD eliminates all mechanical components of a conventional mill drive system, such as ring-gear, pinion, gearbox, coupling, motor shaft and motor bearings: By mounting the rotor poles directly onto the mill, the mill itself becomes the rotor of the gearless motor.
Ringmotor of the Gearless Mill Drive (GMD) System. CYCLOCONVERTER Principle The Cycloconverter is a frequency changer which converts a poly-phase voltage with the frequency f1 into a single or poly-phase voltage with a different, lower frequency f2. On Gearless Mill Drives (GMD), the operational output frequency varies from 0.3 Hz up to about 6 Hz.Increasing availability through advanced Gearless Drive,The Gearless Mill Drive system consists of the ring motor with its feeding cycloconverter, pre-installed in an E-house. It also includes the excitation rectifier, the automation sys-tem (for mill and motor) including HMI, monitoring and diagnostic system, MCC’s (for mill and drive auxiliaries),

CHH624 Gearless Mill Drive Operation and Maintenance Course goal The goal of this course is to provide participants with the required practical knowledge and in-formation on safe operation and maintenance of the gearless mill drive (GMD) system. This training will help to enhance the operation and the maintenance of the GMD in order to ensureTECHNICAL AND COMMERCIAL BENEFITS OF GEARLESS ,The first Gearless Mill Drive (GMD) with a power of 6.5 MW was The current in each phase is controlled by a 12-pulse ranges from the starting point up to the drive operational range. In this range, the output has a constant torque capability with varying power.

SIMINE MILL GD outstanding reliability at your hand The Gearless Concept The Gearless Drive avoids any contact between the rotating mill and the static parts of the motor. This enables a contin-uous workflow without maintenance on the gears or the pinions. What used to Preprint 13-050,Presently the gearless drive is more costly than the complete mechanical portion (mill rotating element and accessories supplied by the mill manufacturers) and hence the customer/consultant needs to have two parties to deal with from the start of any project. There is an interface between the mill vendor and the gearless motor supplier.
Guerrero and Pontt investigated the oscillatory torque caused by dead time in the current control of a high-power gearless mill drive.
