VSDs for copper mine

Third Quarter 2005 News & events

Danfoss South Africa has recently completed the supply of VSDs for the Kansanshi Copper Project in Zambia. Kansanshi is an open cast mining operation that is 80% owned by mining company, First Quantum Minerals.

The project feasibility study and detail plant design was carried out by GRDMinproc of Perth, Western Australia, and Danfoss was awarded the contract via its Bryanston-based South African company, GRDMinproc, for the supply of VSDs ranging from 1,1 to 200 kW, 525 V. The VSDs supplied were the VLT5000 series complete with Profibus as the communications option on board. Danfoss was chosen above a number of other VSD manufacturers as a result of its good track record with reliable and user-friendly products in similar applications. Danfoss VSDs are chosen to operate a variety of equipment such as pumps, agitators and fans.

VSDs are commonly used on centrifugal pumps throughout the mining industry for process control, by means of controlling the speed of the electrical motor the flow rate, agitation and blower airflow can be controlled.
