Selecting Inching Drives for Mill and Kiln Applications Glen Cahala Frank C Uherek, Principal Engineer - Gear Engineering Software Development Abstract The inching drive, also known as a barring or auxiliary drive, is an important component of any mill or kiln installation. It is used for maintenance and inspection purposes, as
The gearless mill drive is covering the upper power range of the mills. The torque is transmitted to the mill directly through the magnetic field in the air gap of the motor, eliminating the gear reducer, the ring-gear and the mechanical related issues faced by maintenance with ring-geared mills.
BALL MILL DRIVE MOTOR CHOICES - artec-machine. The mill used for this comparison is a 4.4-meter diameter by 13.6 meter long ball mill with a 5000 HP drive motor. It is designed for approximately 90 s.ton per hour. This type two-compartment mill is a state- of-the-art shell supported cement finish mill.

Both the SAG mill and ball mill are each driven by two gear units. Because, on a conventional drive variant, only one engagement per pinion with the girth gear is possible per side, an economic power limit of about 8 MW per drive is in effect. With the DMG2 gear units, Siemens said this limit expands to as much as 12 MW per drive.

Several types of ball mill drives can be furnished, made up of various combinations of gearing, motors and transmission equipment. The correct combination to be selected takes into consideration power requirements, gear ratings, floor space, interference from other plant equipment and motor characteristics. The main types are described and illustrated on these pages.
Two general classifications of gearing are used for ball Mill drives. These are the spur gear and the helical gear. Helical gearing may be either of the single helical or double helical (Herringbone) design. SPUR GEARS These are generally furnished on the smaller diameter mills using V-belt drives or reducer drives. Spur gears and pinions are cut with teeth of the full depth involute tooth ...
