摘要
针对沥青搅拌设备多层振动筛筛分效率问题,对某厂生产的振动筛的筛分效率进行了试验,测试了该振动筛的振动参数和振动筛的应力,对各点振幅进行了检测与分析,得到振幅的分布,找出了造成筛分效率不高的主要原因是振幅较低且振幅在筛体的不同位置呈不均匀分布,提出了增大激振力的方法来增大振动筛的振幅和改善筛体振幅均匀性并提高筛分效率。
The vibration screen was tested about the screening efficiency in the asphalt mixing plant.The vibration parameter and the stress parameters on the vibration screen were tested.The amplitude of each point was detected and analyzed,and then the distribution of the amplitude was obtained.The low screening efficiency is mainly due to low amplitude and different amplitude in the different locations in the screen.The method of increasing the vibration force was used to increase the amplitude and improve the uniformity amplitude of the screen in order to increase the amplitude of screening efficiency.
