"Industries such as coal, steel, mining, cement, aggregates, biomass, recycling, manure & fertiliser, smelters & foundries rely on belt conveyors for materials handling; However, carryback of materials that stick to the belt significantly affect the performance and durability of conveyors. These ""fugitive materials"" drop and contaminate rollers increasing clean-up and maintenance costs in addition to reducing the effective capacity of the belt and increasing energy costs due to the high redundant load. The industrywide solution is to use belt cleaners, which are predominantly cast polyurethane (PU) scrapers with the tip held in contact with the moving belt to scrape it.The materials and mechanical requirements of PU scrapers are surprisingly complex as the tip must be relatively soft to conform to the belt surface and have good wear resistance; Conversely, it must have sufficient mechanical stiffness such that it can be clamped and held tightly against the belt without deflecting. There has been little or no innovation since the last generation of scraper blades were developed and they are available from a wide range of manufacturers. A smaller stiffer blade with the same conformability and improved wear properties means that the efficiency of the design of the clamping mechanism can be improved and maintenance is reduced along with overall costs.Watts Urethane Products (WUP), a manufacturer of cast PU belt scrapers, has developed an improved belt scraper material targeting the £400m World market for belt cleaners. This project offers the potential for WUP to become the technology leader in belt cleaner blades."

“煤炭、钢铁、采矿、水泥、骨料、生物质、回收、肥料和肥料、冶炼厂和铸造厂等行业都依靠带式输送机进行物料搬运；然而，粘在输送带上的物料回运会严重影响输送机的性能和耐用性。这些“外溢材料”掉落并污染滚筒，除了降低输送带的有效容量并增加能源成本外，还增加了清理和维护成本。 高冗余负载。全行业的解决方案是使用皮带清扫器，其主要是铸造聚氨酯 (PU) 刮刀，其尖端与移动的皮带接触以进行刮擦。PU 刮刀的材料和机械要求非常复杂，因为尖端必须相对柔软，以符合皮带表面并具有良好的耐磨性；相反，它必须具有足够的机械刚度，以便可以将其夹紧并紧紧地靠在皮带上，而无需 偏转。自从开发出上一代刮刀刀片以来，几乎没有创新，并且可以从许多制造商处获得它们。具有相同顺应性和改进的耐磨性能的更小、更硬的刀片意味着可以提高夹紧机构的设计效率，并减少维护和总体成本。铸造 PU 皮带刮刀制造商瓦茨聚氨酯产品 (WUP) 开发了一种改进的皮带刮刀 该材料瞄准了价值 4 亿英镑的全球皮带清扫器市场。该项目为 WUP 提供了成为皮带清扫器刀片技术领导者的潜力。”
