Study of the dynamics and analysis of the effect of the position of the vibration motor to the oscillation of vibrating screen

Abstract

Abstract A vibrating screen is a device for sorting materials, which is widely used in screening plants. The working ability of a vibrating screen relies on various parameters, such as dynamic parameters, technological parameters, and so forth. If it is necessary to find a reasonable set of parameters in order to enhance the machine’s performance, it is essential to set up the vibration equation of the vibrating screen. This is also a part of the research content that the article mentions. The next step is to establish the equation of motion of random point-P on the screen box, conduct the simulation, and discuss the effect of the position of the vibratrion motor on the oscillation of vibrating screens. The result reveals that the farther the point is from the focus of vibrating screen, the higher the effect of the vibration motor placement on the amplitude of vibration will be. The points are symmetrical with each other across the focus tend to create the rule of change is opposite. When the vibration motor is moving in the positive direction of the horizontal direction, the vertical oscillation amplitude of the points lying on the upper sieve will increase gradually, while the bottom points will decrease progressively. When the vibration motor is moving in the negative direction of the horizontal direction the change rule is opposite to the case of positive direction; if the vibration motor is 0.3 meters away from the focus of screen, the vertical vibration amplitude of the points on the sieve reaches the maximum value. The research results are of considerable significance to reasonably design parameters for vibrating screen working well.
