Mining Screen - Perfect for Separating, Grading & Sorting Operations
In its simplest form, the mining screen is a surface having many apertures, or openings, usually with uniform dimensions. Particles presented to that surface will either pass through or be retained, according to whether the particles are smaller or larger than the governing dimensions of the aperture.

Vibrating Screen Types - Blog
Inclined Screen. Inclined screens are the most basic type of screen, fixed to an inclined frame at an angle of between 15° and 30°. The entire body of the screen vibrates on helical springs circularly with the same characteristics and material flow is supplied by gravitational acceleration. The slope of the inclined screen is fixed, although ...

Some Basic Factors Affecting the Screen Performance of Mining Screens
Aggregates Distributed on Screen Deck Main Factors Particle Size 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.
