EMZ was able to complete the manufacturing for two hammer mill drives for the HAZEMAG company in record time in December 2022. These motors have been manufactured order-specifically for use in ATEX zone 22 in the dust explosion hazardous area. For the design of this machine, in addition to the high requirements of the ATEX directives and the influences of the frequency converter, the operating principle of the working machine had to be taken into account, which involves an extremely high mass moment of inertia. For intelligent monitoring, both motors were equipped with two vibration sensors.
The result is two powerful drives that were tailored precisely to the application in close cooperation with the customer and leave no room for compromises.
We would like to say a big thank you to HAZEMAG and all involved for the excellent cooperation!
