Modernization and automation of the adjustable electric drive of the main mining conveyers of JSC Belaruskali
Modernization and automation of adjustable electric drivers of the main mining conveyers was carried out at Production Units 2, 3 and 4 of JSC Belaruskali.
Before the modernization the main mining conveyers were driven by direct starting. During the starting dynamic strikes affected the mechanic system of the conveyer in a damaging way. All the elements, from the conveyer belt to the drum, suffered brief but heavy loads. As a result the conveyers often stopped working and demanded regular maintenance.
The main technical solution:
Replacing the existing electric drives into less powerful ones and reducing the number of electric drives
While carrying out modernization we applied:
Siemens electric drives
Frequency transformation plants with fluid cooling produced by PASSAT Holding on the basis of Siemens converter Sinamics S120
The following operations were carried out:
Purchase, manufacture and delivery of equipment, materials and goods to the customer,
Assembly, starting-up and adjustment of the delivered equipment.
Modernization allowed the customer:
to reduce more than two times the installed capacity of the electric drives;
to reduce the specific consumption of electric power for ore delivery by 37 %;
to increase the efficiency of the belt:
to prevent high starting current in the network.
