NEW VERTICAL MILL DRIVE SOLVES SURGE PROBLEMS AND IMPROVES RELIABILITY

Siemens Industry Drive Technologies Division has launched a Flender vertical mill drive that prevents load surges arising from short term power interruptions and optimises performance between drive and mill.

The EMPP (electrical motor and two planetary gears) mill drive is an innovative drive concept, featuring a newly developed motor in which the gear housing is built under the planetary gear. The power transmission features a permanent magnet synchronous motor with highly efficient cooling system, and the drive is controlled by a frequency converter, ensuring maximum running smoothness/optimum grinding results and improved reliability through fewer components.

Vertical mills are used to crush raw material in materials handling applications. The new units are available in power ratings from 500kW to 15MW, and above a certain size can be delivered in two parts for site assembly.

The compact footprint means no laborious retrofitting is necessary. This drive meets the requirements of the ATEX Directive.

More information on the Flender range of gear units is available from Siemens Industry on 01274 657700, by emailing anna.grimshaw@siemens.com or see the new drive on the Siemens website at www.siemens.com/flenderempp
