Underground coal mines and tunneling contractors will continue to use the proven concept of distributed power to their best advantage, but now at least two of the longer surface conveyors in development will be installing intermediate drives in 2005.
In Germany, RWE Rheinbraun operates coal conveyors with 30,000 tph capacities and other surface coal mines have plans to soon be approaching these loads. With capacity increases, comes increases in belt speed; again demanding better installation, manufacturing tolerances and understanding of resistances and power.
Each time we go longer, higher, wider or faster, we stretch the limits of our analytical tools to predict system performance. And because each conveyor is unique, the only way we have to predict performance is our numerical analysis and simulation tools. Therefore it is imperative we continue to improve our design tools as our goals get bigger.

摘要 按散装材料运输的要求，带式输送机行业开展更高吨位传输距离更远，更多样化的航线。为了跟上时代，重要的技术已要求向系统的设计，分析和数值模拟的领域跨越。当传统部件应用在像平曲线和中间驱动器等非传统应用就要求改变和扩大皮带输送机的可能性。复杂的传输应用方面的机器，就要确保对可靠性和可用性能进行审查的数字工具。论文网
介绍
虽然此演示文稿的标题表示带式输送机技术的“新”的发展将呈现，大部分意见和这里提供的方法已经有一段时间了。我们认为任何单个设备或思想的提出对大多数的你们来说比较“新颖”。“新”可以是正在建的有成熟的组件的意义重大的和复杂的系统。“新”也可以是用来把这些部件连成旨在解决不断扩大的散装材料处理需要的独特输送系统的系统设计工具和方法。 “新”还可以是首次计算机模拟系统测试（调试）产生准确能源效率的系统性能不断增加的能力。
因此，该演讲的主要焦点将是复杂的系统设计方面的最新进展，妥善设计并优化今天的长距离输送要求，这显得至关重要。
