screen analysis. [ ′skrēn ə‚nal·ə·səs] (engineering) A method for finding the particle-size distribution of any loose, flowing, conglomerate material by measuring the percentage of particles that pass through a series of standard screens with holes of various sizes.


Screening separates the sand and gravel into different size ranges. Water is sprayed onto the material throughout the screening process. After screening, the sized gravel is transported to stockpiles, storage bins, or, in some cases, to crushers by belt conveyors, bucket elevators, or screw conveyors.


When the inclination angle increases further, the sieving efficiency becomes low due to sharp decrease of the horizontal projection size of mesh aperture, sharp increase of the moving speed of particles on the screen surface, and shorter stay time of particles on the screen surface.

The screen box uses shafts with counterweights or exciters to cause the material bed to vibrate. Through the vibration, larger particles work their way to the top of the material bed, while the smaller particles make contact with the screening surface. Because they are inclined, circular-motion screens provide a high travel rate.


angles, which is widely used in screening plants [1-3]. The screening efficiency is one of the most important criteria to evaluate the machine performance, and it depends on various factors, such as the deck inclination angle (screening surface angle), vibration frequency, vibration amplitude, material properties, etc [4-9].

Vibrating Screen Types. Screen Types 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.


Sieving is a method of using a sieve to distinguish small particles from bigger particles. It is used in flour mills or building sites. Impurities such as husks and stones are extracted from wheat at flour mill. They remove pebbles and stones from sand by sieving.
