Gearless Mill Drives Beneficiation Siemens Global

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 combined total of over 500 years in operation time and this number is steadily growing even as you read this. This is a benchmark we are immensely proud of.

Gearless Drives Siemens

Since 1998, Siemens has been providing gearless drive systems for 40-foot SAG mills. And over the past three years the company has received ten orders for this type of mill, rated at up to 28 MW. In 2010, Siemens proudly announced the sales re- lease of a 42-foot gearless drive.

Whether you’re talking about SAG or a ball mill, space is a delicate issue, especially in the concentrator. That’s why we always design our Gearless mill drives drives to combine maximum performance with limited space requirements. Suitable foundation and adequate ground conditions Since our solutions have a low motor weight, this notice-ably reduces the demands on the foundation and

The mill, the first of five to be installed at Sino, has a diameter of 12.2 m (40 ft), is 15 m (49.2 ft) long, and will be powered by a 28-MW Siemens GMD. Siemens also supplied the gearless drives for a 36-ft SAG mill with a rated power of 15 MW and a 26-ft ball mill with 15.5 MW of rated power recently installed at the Minera Los Pelambres copper operation in Chile.

Innovative Gear Drive Solution for Grinding Mills E & MJ

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. The key, Siemens explained, is that there are two pinions
