ABB to supply gearless mill drive systems to Rosemont Copper
 
ABB為Rosemont 銅業提供無齒輪磨機驅動系統

Baden, April 21, 2008 – ABB won a multi million order from Rosemont Copper Company to supply three 16.4MW gearless mill drive (GMD) systems for Rosemont’s new copper mine near Tuscon, Arizona, USA. One GMD system will be installed on a 36’ SAG mill and two on 26’ ball mills, which will be supplied by Polysius, one of the leading engineering companies equipping the cement and minerals industries. Start-up of the mills is scheduled for 2011.

Baden4月21日消息——ABB從Rosemont銅業公司獲得了一份數百萬美元的訂單，為Rosemont公司在美國亞利桑那州Tuscon市附近的新銅礦廠提供三套16.4MW的無齒輪磨機驅動系統。其中一套無齒輪磨機驅動系統將安裝在一個36’凹形磨機上，兩套安裝在26’球形磨機上，這些磨機由Polysius公司提供，Polysius公司是為水泥和采礦行業提供設備的領先工程公司之一。

Each GMD system comprises transformers, ring motors and a complete E-house. With a GMD as a variable speed drive, mills start smoothly and without any mechanical stress and the customer’s requirements are fulfilled with respect to flexibility and adjustability of the process, allowing maximum control over the grinding process.

每一套無齒輪磨機驅動系統包括變壓器、環電動機和一個完整的E型外罩。利用無齒輪磨機驅動系統作為變速驅動，磨機可以順利啟動，沒有任何機械應力，而且尊重過程中的靈活性和適應性，滿足了客戶的需求，使得研磨過程具有最大的控制權。

Furthermore, ABB gearless mill drive systems feature several benefits compared to conventional geared drive systems: they provide energy efficiency, superior reliability, availability, extended life span as well as frozen charge protection and positioning in creeping and inching mode without additional motor and controlled roll-back.

此外，ABB無齒輪磨機驅動系統于傳統的齒輪驅動系統相比具有一下的優點：它們提供了能源效率，卓越的可靠性，可用性，更長的使用壽命，以及冰凍充電保護和以蠕緩和循序漸進的方式定位，無需額外的電機和控制的重新運行。

Including the Rosemont order, ABB has already won projects for eleven installed or ordered GMD units in the USA. ABB provides superior after sales service in the USA; this order reinforces the Company’s strong presence in the North American market as well as the mutual cooperation with Polysius.

包括Rosemont 公司的這份訂單，ABB已經在美國獲得了11份無齒輪磨機驅動系統項目訂單。ABB為美國客戶提供卓越的售后服務，這份訂單加強了公司在北美市場的強大布局，同時也加強了與Polysius公司的相互合作。

Hanspeter Erb, Head of ABB Switzerland Drives Applications, said: “Quality teamwork and customer service are decisive when driving the heart of any mining operation. The ABB and Polysius worldwide experience come together for this important Rosemont investment in superior efficiency, reliability and output.”

ABB瑞士驅動應用部主管Hanspeter Erb表示：“優質的團隊和客戶服務在驅動任何采礦作業的核心的時候都是決定性的。ABB和Polysius公司的全球經驗結合在一起，為Rosemont這個重大投資提供更高的效率、可靠性以及產出。”
