32 ft Diameter SAG mill – multi segment mill installation at Tietto, Abujar Gold Project

NCP successfully completed the supply of 32ft dual drive SAG mill for TIETTO’s ABUJAR GOLD project in Côte d’Ivoire, West Africa. NCP was awarded this contract by Australian exploration company Tietto Minerals and has delivered on all the contractual commitments made at sales stage for an accelerated delivery.

The contract allowed for the supply of a Ø32 x 20ft, 11.5MW Dual Drive Bi-directional Semi-autogenous (SAG) mill, supported off hydrostatic trunnion bearings.

The dual pinion drive train consists of two existing 5750kW, 6 pole slipring electric motors converted to operate as a squirrel cage induction motors allowing operation through a MVW3000 VVVF Variable Speed Drive.

The specified duty of the mill is to process Run of Mine (ROM) material fed at a rate of 500TPH from the primary crushing circuit at a F80 material size of 159mm, delivering a product of P80-115µm. The mill size selected offers slightly more capacity providing upside potential in terms of throughput.

The mill was delivered within 28 Weeks ex works from raw components arriving in South Africa, once again highlighting NCP’s world leading ability to meet tight project deadlines.

NCP’s scope of work included the supply of the mill, installation and commissioning. NCP will supply the client full aftermarket sales service, on-site assistance and technical support.

“Abujar first gold pour achieved within 12 months of breaking ground and the start of construction.”

NCP supplied and completed the installation of the 32ft SAG Mill on-time and is proud to have met the client’s expectations in this regard.

NCP is looking forward to supporting Tietto Minerals into the future and ensuring that this mill continues to deliver what it is designed to do.
