1、 The physical properties of the material screened by the vibrating screen include the particle size composition, humidity, mud content, and particle shape of the material itself. When the content of fine particles in the material is high, the productivity of the sieve is also high. When the humidity of the material is high, the screening efficiency will decrease. But the larger the sieve size, the smaller the impact of moisture. Therefore, for wet materials with high moisture content, in order to improve the screening process, it is generally possible to increase the sieve size or use wet screening. When the mud content of the material is high (when the mud content is greater than 8%), wet screening or pre washing should be used.

2、 The influence of the properties and structural parameters of the vibrating screen surface. The vibrating screen causes particles to move vertically with the screen surface, resulting in high screening efficiency and high production capacity. The relative motion between particles and the screen surface is mainly parallel motion in flat vibrating screens, which have low screening efficiency and production capacity. For a certain material, the productivity and screening efficiency of the sieve are determined by the size of the sieve holes. The productivity depends on the width of the screen surface, with a wider screen surface resulting in higher productivity. The screening efficiency depends on the length of the screen surface, with a longer screen surface resulting in higher screening efficiency. The general aspect ratio is 2. The larger the effective vibrating screen area (i.e. the ratio of the screen hole area to the entire screen surface area), the higher the productivity and screening efficiency per unit area of the screen surface. The larger the screen hole size, the higher the productivity and screening efficiency per unit screen surface.
