Do more with less go gearless. Mine operators are challenged with moving more material on conveyors that may cover distances in the tens of kilometers and ascend steep gradients. To increase overall reliability, mining companies also want fewer transfer stations between conveyors, which may require wider and longer belts.
Gearless motors up to 22 MW are in service in many of these ore processing plants. Gearless motor drives are also known as "ring motors" or "wrap around motors." The motor consists of a large number of magnets placed circumferentially on the shell of the grinding mill. This is similar to the rotor of a conventional motor.
Its gearless drive system is equipped with two lowspeed synchronous motors with cycloconverters (installed power of MW, motor speed of 63 rpm, rated torque at 576 kNm) and a motor cooling system. Load sharing between the two drives can be adjusted according to the .
The SAG mill was fitted with a gearless drive with a power rating of 24 MW and the ball mills were also fitted with gearless drive systems, each providing MW.
3 days ago· In all, two 28megawatt gearless mill drive systems (GMDs) are in use at the mine''s 40ft SAG mills, and four GMDs are employed in 26 football mills. "Gearless mill drives are the ''workhorses'' for grinding operations, which are at the heart of any mine," ABB''s Cobre Panama project manager Rene Chacon said.
