The Siemens 42ft gearless mill drive, still an evolutionary design

2021. 7. 29.  • Motor behavior during normal operation with a loaded mill The result is the design of a Gearless Mill Drive motor for a 42ft Grinding Mill providing up to 35MW of power. Evolution is still the main GMD design philosophy, but realistic and proven computer models help to look beyond experience, where testing is impossible.

Literature Review: Gearless Motor Failures – A Mill

2014. 9. 10.  The origins of the failure can be traced back to c. 1994 when PT Freeport Indonesia ordered its first gearless drive for their 34 ft SAG mill. The motor had to fit through a tunnel on the road to the site. This necessitated a change in the frame design from that used in older motors to allow clearance in the tunnel [8].

Top Causes of Machine Vibration Fluke

2021. 5. 9.  Vibration is simply a back and forth movement—or oscillation—of machines and components in motorized equipment. Vibration in industrial equipment can be a symptom, or cause, of a problem, or it can be associated with normal operation. For example, oscillating sanders and vibratory tumblers rely on vibration

ball mill motor causes of vibrations

An Experimental Analysis Of Vibration Of A Ball Mill . citeseerx document details this paper deals with the experimental investigation of vibrations of a ball mill under variable load. the common causes of vibrations of the ball mill are described in short. the exciting frequencies at which the possible causes of vibration can be recognised are estimated for all principle parts of the ball mill.

Grinding Mill Foundations

2014. 9. 23.  Most of our work since 2000 has been in developing grinding mill foundations to avoid vibration and unacceptable deflections. On a recent project for a plant in Peru, the client was told by the mill vendor that there was no need to do a systems (dynamic) analysis on the mill foundations because the mills on that project were gear driven rather than being driven by ring motors (gearless drives).

How digitalized gearless drive results in energy

Eleven 5MW gearless drives with synchronous motors running at low speeds (50-60rpm) drive three conveyors; two with four motors each and one with three. Two 20MW conveyors transport the ore from the open pit operation to the surface, overcoming an elevation change of around 1,300m, while the second conveyor feeds into a slightly smaller, 15MW, overland conveyor.
