大型香蕉筛应用在选煤厂分级、脱泥、脱介和脱水作业等工艺环节中。在实际应用中,大型香蕉筛出现了横梁断裂、侧板裂纹及弹簧压断等诸多问题,其中横梁断裂最尤为突出,严重影响了选煤厂的正常生产。以BLS3661大型香蕉筛为例,对大型香蕉筛横梁断裂的问题进行了研究,并提出了解决方案。 Large banana screen used in coal preparation plant grading, desliming, de-referral and dehydration operations and other processes. In practical application, there are many problems such as beam breakage, side crack and spring crushing of large banana screens, among which the beam breakage is the most prominent, seriously affecting the normal production of coal preparation plant. Taking BLS3661 large banana screen as an example, the problem of breaking of large banana screen beam was studied, and the solution was put forward.
