Influence of Flat-pendulum Sieve Parameter Interaction on Layering Effect Based on PSO-BP Algorithm

Taking the parameters of the flat-swing dual operation mode linear vibrating screen, namely amplitude, vibration frequency, vibration direction Angle and swing Angle, as the research object, the influence of the interaction of different parameters on the stratification effect is explored. [Objective] In order to more intuitively analyze the complex influence relationship between the screening parameters of the vibrating screen and the delamination effect and the dynamic characteristics of the material group in the screening process, it is convenient to carry out the optimization research of the parameters of the vibrating screen to improve the screening and layering effect and screening efficiency. [Method] Firstly, solid works are used to establish a vibrating screen to simplify the three-dimensional model, the orthogonal test method is used to design the test, and the corresponding factors in the test scheme are imported into EDEM, and the neural network is used as the carrier to explore the change law of the four parameters of the amplitude, vibration frequency, vibration direction angle and swing angle of the vibrating screen and the layering effect, and the data results are obtained for deep learning. [Result] The influence weight analysis of screening parameters and different layering effects showed that the vibration frequency, vibration amplitude, vibration direction angle and swing angle had the most significant effects, so these four parameters were combined to characterize the operating state of the vibrating screen to clarify the change law of different parameters on the layering effect of the material body. When the amplitude is 3.4 mm, the vibration frequency is 14.8 Hz, the vibration direction angle is 44.1°, and the swing angle is 0.6°, the layering effect of the material group is obvious, and the overall distribution of fine-grained materials and the screen surface end. [Conclusion] This article takes the vibration parameters of the sieve machine as the variable and the material body layering effect as the optimization goal, in order to provide inspiration for the optimal design of the vibrating screen.
