ABB節能驅動器將安裝到世界上功率最大的研磨機上 瑞士蘇黎世5月31日新聞－電力和自動化技術世界領袖企業ABB獲得了瑞典煤炭開采企業Boliden授予的價值2700萬美元的訂單。ABB將為兩臺新型的研磨機提供無齒輪驅動系統，這兩臺研磨機將提高歐洲一個最大的銅礦生產力。 無齒輪研磨驅動器將被安裝在Boliden公司的Aitik銅礦上，該銅礦位于瑞典北部Gällivare，在這里將裝配兩臺新型38-foot自磨機。 該研磨機驅動器功率為22.5MW，2009年底裝配運行時將是世界上功率最大的驅動器。每臺驅動器每小時將驅動研磨機研磨2,200噸礦石。這樣的功率將使銅礦壽命至少延長到2025年，年生產力將達到3600萬。 ABB過程自動化部門總裁Veli-Matti Reinikkala “ABB在生產無齒輪研磨機驅動器領域占在行業前沿，該技術支持重要的礦山應用，如需要強力配合節能和連續可靠性的的礦石加工，” 自磨機將大塊礦石送入轉鼓中研磨成小塊。研磨機及其無齒輪驅動器是該行業中最大型的設備之一（環行馬達約20米高），也是選礦廠的關鍵設備之一。隨著大塊礦石研磨為小塊礦石，先進的技術將強大的力量轉換為高生產力。 該合同還包括ABB提供備件，網絡研究，安裝監督以及試運行，轉鼓機預計在2010年投入運行，并將完全替代目前的粉磨站。 ABB（ www.abb.com）是電力和自動化技術領域的全球領導廠商，致力于為工業和電力行業客戶提供解決方案，以幫助客戶提高業績，同時降低對環境的不良影響。ABB集團的業務遍布全球100多個國家，擁有109,000名員工。 original text： [COLOR=#708090]ABB wins $27-million mining order in Sweden Energy-efficient ABB drives at heart of world‘s most powerful grinding mills Zurich, Switzerland, May 31, 2007 – ABB, the leading power and automation technology group, has won an order worth about $27 million from Swedish mining company Boliden. ABB will supply gearless drive systems for two new grinding mills that will increase production at one of Europe‘s largest copper mines. The gearless mill drives will be installed at Boliden‘s Aitik mine, located near Gällivare in northern Sweden, where they will power two new 38-foot autogenous grinding mills. At 22.5 megawatts （MW） each, the mill drives will be the most powerful in the world when they become operational at the end of 2009. They will drive mills with a capacity to grind about 2,200 tons of ore per hour each. With this expansion, the mine‘s life will be extended to at least 2025 and production capacity will double to 36 million tons a year from 18 million. “ABB pioneered gearless mill drives. The technology supports important mine applications like ore processing where huge volumes and brute strength must be matched to energy-efficient operation and around-the-clock reliability,” said Veli-Matti Reinikkala, head of ABB‘s Process Automation division. An autogenous mill uses large pieces of ore to grind smaller pieces in a large rotating drum. The mill and its gearless drive is one of industry‘s largest installations （the ring motor is almost 20 meters high） and one of the pivotal applications in a concentrator plant. Advanced technology converts brute strength into high productivity as ore is reduced to small particles. The scope of the ABB contract includes spare parts, network studies, installation supervision and commissioning. The new concentrator is scheduled to start operation in 2010, and will completely replace the current grinding plant.
