ABB为Rosemont 铜业提供无齿轮磨机驱动系统

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从Rosemont铜业公司获得了一份数百万美元的订单，为Rosemont公司在美国亚利桑那州Tuscon市附近的新铜矿厂提供三套16.4MW的无齿轮磨机驱动系统。其中一套无齿轮磨机驱动系统将安装在一个36’凹形磨机上，两套安装在26’球形磨机上，这些磨机由Polysius公司提供，Polysius公司是为水泥和采矿行业提供设备的领先工程公司之一。

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.

每一套无齿轮磨机驱动系统包括变压器、环电动机和一个完整的E型外罩。利用无齿轮磨机驱动系统作为变速驱动，磨机可以顺利启动，没有任何机械应力，而且尊重过程中的灵活性和适应性，满足了客户的需求，使得研磨过程具有最大的控制权。

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无齿轮磨机驱动系统于传统的齿轮驱动系统相比具有一下的优点：它们提供了能源效率，卓越的可靠性，可用性，更长的使用寿命，以及冰冻充电保护和以蠕缓和循序渐进的方式定位，无需额外的电机和控制的重新运行。

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 公司的这份订单，ABB已经在美国获得了11份无齿轮磨机驱动系统项目订单。ABB为美国客户提供卓越的售后服务，这份订单加强了公司在北美市场的强大布局，同时也加强了与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瑞士驱动应用部主管Hanspeter Erb表示：“优质的团队和客户服务在驱动任何采矿作业的核心的时候都是决定性的。ABB和Polysius公司的全球经验结合在一起，为Rosemont这个重大投资提供更高的效率、可靠性以及产出。”
