Resilient motor unfazed by thin air

Menzel Elektromotoren from Berlin, Germany recently delivered two motors for a cement mill and a classifier to a cement plant in Bolivia.

The mill, which manufactures high-strength cement with 5000 Blaine, is not only the country's first vertical roller mill for cement grinding. At 4000 m above sea level it is also the highest installed elevation of an OK mill in the entire Americas. Therefore, very particular technical attention had to be paid to the motors' durability and ruggedness. Menzel modified their maintenance-friendly standard motors designed for the cement industry even further so they would withstand the special operating conditions.

During the planning phase, the drive engineers and the customer closely cooperated in determining the most efficient and economical application design for the drive solutions, eventually deciding on a change of voltage levels, construction of a foundation plate and the installation of a vibration monitoring system for integration into the control as requested by the customer. The German motor manufacturer's flexibility and speed were once more decisive for this customer's placement of an order. After commissioning in September 2016, more than ten motors from Menzel will be powering machines in the Bolivian cement plant.
