30米~2共振筛是我国目前使用的面积最大的筛分机械。该筛自投产以来,由于其产量大,效率高,动平衡好,传给基础的动力小等优点而深受用户欢迎。但也因其存在着横梁断裂等结构强度上的问题,给生产使用带来了很多困难以致于不能正常投产。为了尽快解决这一问题,查明断裂的原因,给修改设计提供依 Resonance sieve of 30m ~ 2 is the largest screening machine currently used in our country. Since the screen put into operation, due to its large output, high efficiency, good balance, the basis of power to small, and other advantages and welcomed by users. However, due to the structural strength problems such as the breakage of beams, it brings many difficulties to the production and use so that it can not be put into operation normally. In order to solve this problem as soon as possible, identify the cause of the fracture, to provide a modified design
