输送带的选型 Selection of conveyor belts 选择合适的输送带品种规格可以延长输送带的使用寿命，保证生产的持续稳定，降低生产成本和维护费用。 The selection of the suitable conveyor belts can prolong the service life of the conveyor belt, ensure the continuous stability of production, and reduce the cost of production and maintenance. 选择输送带时（包括替换带）必须考虑以下几个方面的问题： Selecting the conveyor belt (including the replacement belt) must consider the following questions: a.所运物料的品种、粒度有无变化 The variety and granularity of the materials are not changed b.最大运载量（峰量）有无变化 There is no change in the maximum capacity c.设备工作能力、工况条件有无变化，工作环境 The working conditions of equipment and operating conditions are not changed 有无变化。 With or without changes. 骨架材料种类、结构、层数的选择： The selection of type, structure, and number of skeleton materials: a.输送带骨架材料的发展方向 A. The development direction of the skeleton material of the conveyor belt 叠层式输送带带芯由天然纤维向合成纤维方向发展，由多层向少层方向发展，由低强度、低模量向高强高模方向发展。棉纤维织物输送带在国外已基本淘汰，在国内也逐渐被尼龙、聚酯织物输送带所取代。在大功率输送中，需要高强度的输送带，钢丝绳芯输送带整逐步替代层数较多的织物芯输送带。 Laminated conveyor belt core is made of natural fibers to develop in the direction of synthetic fiber, by multi-layer to develop in the direction of less layers, from low strength, low modulus to develop in the direction of with high strength and high modulus. Cotton fabric conveyor belt, which has been largely eliminated from abroad, is gradually replaced by nylon and polyester fabric conveyor belt. In high-power transmission, high intensity conveyor belt is required, and the steel wire rope core conveyor belt is replaced by the multi-layer fabric core conveyor belt.
