This solution guarantees safe starting of the mills, decreases the mechanical oscillation during starting and during operation, too. After the successful tests Beremend Cement Mills Co. decided a complete renewal-reengineering oftheir existing equipments and put into operation all of the 12 motors supplied by Ganz Transelektro at the beginning of 2002. Construction The three phase double-cage rotor asynchronous motor is adequate for direct starting. It has a completely closed stator with mounted air-to-air heat exchanger. The roller bearings are provided with automatic greasing. There are intern built-in SKF Vibrational Sensors. The stator winding has F thermal class VPI system insulation. There are Pt 100 winding thermometers provided. General application range Power: 500 kW-2500 kW Օ Frequency: 50-60 Hz Speed: 750-1800 rpm Օ Protection: IP 54 Cooling: IC 611 or other Smart solutions. Strong relationships. For the raw and cement ball-mill twin drives slip-ring or otherwound type rotor motors are used all overthe world. Ganz - first in the world - successfully broke this tradition with double squirrel cage motors supplied to Duna-Drՠva Cement Company at Beremend. This new solution is significantly cheaper also from the investment side compared to the traditional solutions. On one hand the double-cage motor is substantially cheaper than the slip-ring motor - on the other hand the costly starting equipment and the adherent short-circuiting switch together with the controller are not required. The usage ofour solution due to the low operational and maintenance costs further increase the adaptability of this new equipment. CG Electric Systems Hungary Zrt.
