Menzel Motors at the Mining Convention Perumin 35 / Extemin 2022
Visit us at PERUMIN 35/ EXTEMIN 2022, German pavilion - booth number 760-769. Here we show you our motor solutions for the mining industry.
From September 26 to 30, 2022, about 50000 participants are expected in Arequipa, Peru, to visit one of the largest mining trade shows in the industry, PERUMIN 35/ EXTEMIN. MENZEL motors from Berlin will be present with an own booth! Visit us in the German pavilion at booth number 760-769, where Thorben Keune and Anja Leipold will answer your questions about our motor solutions for the mining industry. For your personal appointment, please contact email@example.com.
The Peruvian Mining Association for Engineers (Instituto de Ingenieros de Minas del Perú - IIMP) is holding PERUMIN 35/ EXTEMIN 2022 for the first time again as a presence event after the trade fair was suspended last year due to the pandemic. Messe Düsseldorf is organizing the German participation with the support of the German Federal Ministry of Economics and Climate Protection. As an exhibitor, German companies present their products and services under the "Made in Germany" brand at the Mining Technology Exhibition (part of PERUMIN - Mining Covention)
MENZEL bespoke mining pit fan motors with fin cooling
MENZEL Motors has just recently designed and manufactured three powerful 6600 V squirrel cage motors as integral components for mining pit fans. The customer specified cylindrical motor casings as compact as possible for its underground ventilation system. The greatest challenge was to implement the required rated power of 1700 kW in cylindrical casings.
Menzel therefore designed fin-cooled squirrel cage motors (cooling type IC 411) in frame size 630, an extremely unusual design for motors this large. The manufacture is complex, but the result is optimal for the constricted installation conditions in the mining industry. In order to save additional space, all connection cables are routed out of the pit fan motors and the terminal boxes are mounted outside the fans.
Special rolling bearing setup and a second shaft end
Since the driven fan wheels are mounted directly on the motor shafts, the motor bearing must compensate additional high loads: radial loads up to 27000 N and axial loads up to 27000 N.
For the required bearingservice life of 100,000 hours, Menzel implemented a special rolling bearing setup. In addition, the motors have a second shaft end for a holding brake. The three-phase squirrel cage motors are designed for operation on a frequency converter (duty type S9) with speed changes and reversal of the rotation direction. This allows the pit fans not only to ventilate the mine, but also to extract dangerous firedamp if necessary.
Customized electric motors from Germany for the mining industry
We are a family-run company from Germany that has been manufacturing electric motors for almost 100 years and selling them worldwide. We supply asynchronous motors up to 25 MW and 13.8 kV, either to customer specifications or in standard series - squirrel cage and slip ring motors, as well as DC motors.
We specialize in the adaptation and new production of customized motors of almost all types and industrial applications: Mining, Cement, Steel and many more. MENZEL can rebuild and replace existing motors of all types and power ratings.
Personal advice and fast delivery
Plant and mine operators in more than 75 countries appreciate not only our personal advice, but also the particularly fast delivery of larger electric motors, including special designs. We have one of thelargest warehouses in Europe. With a large selection of brand-new electric motors in our warehouse, we can deliver the right motor within a few days in the event of a plant shutdown.
MENZEL not only manufactures motors for ventilation fans and systems for the mining industry. Our robust, powerful and low-maintenance electric motors are used in mines all over the world: As mill drives, conveyor motors, crusher motors, as belt drives and more - always tailored to your application.
