We provide optimized mill drive solutions for all types of ring-geared mills: low and high speed, single and dual pinion, with and without a gearbox — all designed for reliable, long life and low maintenance operation.

In the 2×5MW dual-pinion ring-geared pebble mill example, one of the inverter units in the ACS 6000 drive is configured to be the "master" and receives the speed reference via the mill controller from the DCS. The other inverter unit is known as the slave and it follows the master drive's speed and torque refer-ence.

When dual-pinion mills are used, care must be taken that the load is shared equally between the two pinions. ABB's fast direct torque control (DTC) ensures accurate and coordinated load- sharing. DTC is the ABB advanced motor control method for drives as it allows precise control of the motor's torque and speed.

drive application is a dual-pinion SAG mill driven by two 5,000 kW wound rotor induction motors (WRIM). Two TMdrive-10SPRs control motor speed by recovering rotor current and returning the power to the utility supply. Configured in a twin motor arrangement, the motors share load in the tandem mill. The Customer Need

ABB's dual pinion mill drive systems provide real time frozen charge protection which is especially important for the operation of the ball mills. Also its dual pinion drives solutions provide the option of variable speed, which enables the end user to increase the availability of the complete production line.

cost issues must be taken into account for choosing one solution or the other. Both solutions can be developed for single pinion or dual pinion applications depending on the power of the driven mill. High speed solution. Typically, a high speed squirrel cage motor with three or four pole pairs is used for this kind of configuration.

b) the simplified direct drive type; a more energy efficient solution either with Low Speed Synchronous Motors (LSSM) and most recently the highly reliable Low Speed Induction Motors [2]. Figure 3 shows a ball mill with a dual pinion drive 2x 6500 kW with low speed induction motors (LSIM). The dual pinion drives demand tight tolerances in the

dual pinion solutions were developed to power the mills. However, realization of the dual pinion solution was only possible when load could be evenly shared between the two pinions. When mill diameter and mill power became again increased, only the Gearless Mill Drive (GMD) could be envisaged to cover this requirement above 10 MW.

The clutch's primary role on the dual-pinion, direct-drive geared mill is to provide smooth starts during mill startup. When the mill is running, the clutch also serves as a torque "circuit breaker," reducing costly repairs and downtime by protecting the pinions and ring gear from potential damage caused by large pieces of grinding material.
