Siemens drives world?s longest conveyor belt
Erlangen, July 20, 2007 – Siemens Industrial Solutions and Services (I & S) has equipped a 19 km long conveyor belt system with drive systems for Alcoa Inc., based in Texas (USA). Siemens systems offer precise methods of control, can be quickly and flexibly to different loads and are highly energyefficient.
Alcoa is a leader in aluminum production. The plant in Rockdale, Texas, needs a constant supply of lignite energy to maintain production throughout the day. To this end, a conveyor belt system transports the necessary coal from the mine to Rockdale Three Oaks, a distance of 32 kilometers.
The critical section in the middle of the road transport, which is approximately 19 kilometers long, is bridged with the longest belt conveyor unique in the world, parts of which must pass through a field uneven. This link between the point where the material comes from the open pit mine and the place from which is then taken to the power plant.
The belt system was equipped with a solution of R & S With Simine product family, which has strong systems and efficient energy transmission. Five drivessystems SIMOVERT MASTERDRIVES VC type, each with 556 kW have been installed. The units are strategically placed so that the completesystem can be optimally operated, stopped and started up. A unit has been installed at the loading point, two units in the middle of the road and two at the point of discharge.
The fiber optic cables between the conveyor belt stations enable the operator to individually control the belt speed, for example by slowing down when the load is too heavy, accelerate or stop quickly. The belt controlsystem prevents oscillations of the belt during starting and stopping. The system was adapted to the following loading conditions: no load, partial load and full load. This method of operation uses much less energy than conventional belt drive uncontrolled.
Moreover, the protection of mechanical components. Round the top of the clock availability with low operating costs has been reached. The units are first powered up to ten percent of the total speed and, after a plateau of about 60 to 120 seconds, thesystem accelerates the rate of 100 per cent target.
Siemens Industrial Solutions and Services Group (I & S) is the integrator of systems and solutions for industrial service providers and global infrastructure services for the plant and projects business covering planning, installation, operation and lifecycle. I & S uses its own products and systems and process technologies in order to enhance productivity and improve competitiveness of companies in the sectors of metallurgy, water treatment, pulp and paper, oil and gas, marine engineering, mining open sky, airport logistics, postal automation, intelligent traffic systems and industrial services. In fiscal 2006 (September 30) I & S employed a total of 36,200 people worldwide and achieved total sales of 8.819 billion, according to U.S. GAAP.
How to Select a Conveyor Belt Manufacturer?
A conveyor belt is used in transporting gods in a warehouse, factory, super markets and variety of other places. It is highly used in the food industry.
A conveyor belt is used in transporting gods in a warehouse, factory, super markets and variety of other places. It is highly used in the food industry. The belts used here are called hygienic conveyors. This is because foods have to be moved through processes for making Catalytic Converters and packing them. This is wholly done by the conveyor belts. Such conveyor belts should meet the standards of hygiene as set by the government of the United States. It is mandatory to comply with these standards. It goes without saying that cleanliness in prepared foods is the topmost priority. Such considerations are also to be made for using belts in chemical and pharmaceutical industry. Now what to consider while selecting a conveyor belt manufacturer of high quality?
The wrong selection of the conveyor belt manufacture will directly affect the company
The development of the financial crisis conveyor industry is a policy of strengthening the roots
008 China International Industry Fair, the number of experts called for, the international financial crisis, China should vigorously conveyor Ye Fa Zhan, Tishengxingye international competitiveness, Zai Opportunities out the financial crisis, Ji Chu further enhance the independent innovation capability and equipment Gong Ye, Zuo strong foundation for the real economy.
Chinese Academy of Social Sciences Institute of Industrial Economics and other experts said Lu Zheng, manufacturing, mining, construction and other industries in three key sectors, manufacturing is the foundation, while the conveyor belt industry is “not a fundamental.” At present, the international financial market turmoil, the industry also faces challenges in the domestic conveyor belt, at this stage to enhance the ability of independent innovation conveyor industry, occupation, industry, high ground is of particular importance.
Lu Zheng that the current comprehensive national advanced manufacturing is still the foundation of economic strength. “15″, China’s conveyor belt industry in manufacturing capacity and product development with the international advanced level and gradually narrow the gap. Has now established a full range and have a considerable scale and level of manufacturing and R & D systems, manufacturing scale ranks 4th in the world, but the conveyor belt industry is still facing the basis of our technology, basic materials, slow development, independent innovation is weak, the low R & D The new market access difficulties in the bottleneck.
China Industrial Design Association Zhu Tao that China conveyor belt industry to achieve the upgrade, completed from the “Made in China” to “Created in China” can not ignore a key – the design, industrial design industrial innovation is actually the soul China industrial design is relatively weak.
World-renowned consultancy Arthur D. Little management consulting firm Global CEO Michael (MichaelR.Tram) Dr. said that the financial crisis on China, with the strength of the country may become the opportunity, especially for the conveyor industry, less so by the financial crisis the industry is the introduction of advanced technology and attain independent core competitiveness, the completion of upgrading the “golden opportunity”, and stronger conveyor industry, will greatly promote the steady development of China’s economy.
HUANG Wen-hu Chinese Academy of Engineering believes that brands with independent intellectual property rights is the key to enhance the conveyor belt industry. High-tech high-quality products is the core of the guarantee of high value-added products. He reminded, the introduction of technology innovation to become the starting point, we must move forward, we must work out equipment industry, “the introduction of – backward – and the introduction – and then backward” cycle.
