aug 18, 2021 generally speaking, the screening effect of materials with higher hardness and better brittleness is better than that of materials with lower hardness and poor brittleness. among them, the particle size and moisture content of the material are the two key factors that affect the screening efficiency of the vibrating screen.

Dem simulation and experimental study on the screening

For an elliptical vibration system, the vibration parameters seriously affect conveying speed and sieving efficiency of the materials. in addition, considering the lack of studies about the elliptical vibration machine, we applied the discrete element method to simulate and analyze the elliptical vibration screening process in this paper. a vibration screening model is particularly based on

mar 14, 2020 5 factors affecting the performance of dewatering screen. the performance of the dewatering screen has a great influence on the screening effect of sand and gravel. choosing a high-performance dewatering screen can bring greater benefits to the sand washing plant. points to know when buying a high-performance vibrating screen. 1.

5) insufficient inclination of screen surface. for the circular vibrating screen, the most common reason for the poor screening effect is the inadequate inclination of the screen surface, so it is necessary to pad the back support. in practical application, the inclination angle of screen surface is more suitable when it is 20 degrees.

the state of screen motion. the practice shows that level or vertical repeating motion of the screen, the screening effect is not good. the vibratory screeners combined the two motion is better. 5. the peculiarity of the material all the size, humidity, friction and flowability of material will affect the screen.
