On-site training from AuCom assists in successful commissioning for MVS starter.
TALCO is Tajikistan’s most important industrial operation, but reliability problems with the ball mills at the Tursunzade facility were incurring maintenance costs and reducing productivity. Working closely with technical experts from AuCom, TALCO installed an MVS soft starter and have improved not only productivity and reliability,
but have also improved the mill’s operation.
The Tajik Aluminium Co. wanted to retrofit a MVS soft starter for ball mills 1 & 2 at their carbon plant in Tursunzade, Tajikistan. The ball mills are connected to two 500 kW 6 kV motors supplied by Tiraspol Motor Company in Moldavia.
The application previously used a hydraulic coupling between the motor and ball mill. But this mechanical starter demanded periodic maintenance and reliability problems meant that key staff were often diverted from other important projects.
AuCom’s representative for this project, STOIK, recommended two MVS-0080-V06 soft starters supplied in an IP54 panel with mains isolation/earth switch. The starter used R-rated fuses and was supplied with a main and bypass contactor.
“Our customers benefit from having a man on the ground to listen and provide advice.” said Alexander Zhukov from STOIK, “Then we work together: customer, representative and manufacturer for a successful commissioning.”
On-site training from AuCom has empowered the site engineers to get a good understanding of the MVS starter.
Ultimately the MVS starter resulted in a saving in time and expense related to the removal of the hydraulic coupling. Due to the removal of the hydraulic coupling, the site is now a dry area where once it was an oily mess. But most importantly the ball mill has a much smoother start, with a 20 second start getting the ball mill moving in a shorter time than before.
Everyone involved was very happy to see the motor starting on the first attempt.
The Tajik Aluminium Company was very pleased with the MVS starter. AuCom had a solutions approach to the job - considering the entire mains supply system, motor and connected load - to provide a complete starting solution via a quality product.
