Some Basic Factors Affecting the Screen Performance of ...

The smaller the particle size to the aperture, the higher the probability of passing the screen, while the nearer the particle size, the lower the probability of passing the screen. Near-sized particles also tend to plug the apertures thereby reducing the available open area. Particle Shape Spherical particles pass with equal probability in any orientation, while elongated, flat …
