Vibrating screen in stone production line counts much in grading limestone and other foreign materials for quality and clean materials. Vibratory sifter is popular among in mining industry now with the development and increasing need on more quality materials.

Here is the working principle and working process as follows.

The main screening assembly of a vibratory screener is suspended on rugged springs that allow it to vibrate freely while minimizing power consumption and preventing vibration transmission to the floor. The assembly is equipped with one imbalanced-weight gyratory motor that creates multi-plane inertial vibration for the purpose of controlling the flow path of material on screen surfaces, and maximizing the rate at which material passes through the screen.

Material is fed into the center of the screen, causing particles larger than screen apertures to travel across the screen surface in controlled pathways, and exit through a discharge spout located at the screen's periphery, while particles smaller than screen apertures pass through the screen onto a lower screen or exit through a lower discharge spout.

Single-deck screeners are generally utilized for "scalping" or "sifting" (removing a small percentage of oversize material through the upper discharge spout), for "de-dusting" (removing a small percentage of undersize material through the lower discharge spout), or for "dewatering" (removing liquid through the lower discharge spout).

Multi-deck screeners (two-deck shown) are generally utilized for "classifying" of particles in three to five predetermined sizes, or when equipped with integral screening decks, for increasing the capacity of a screener without increasing its diameter.
