A screening machine consist of a drive that induces vibration, a screen cloth that causes particle separation, and a deck which holds the screen cloth and the drive and is the mode of transport for the vibration.
There are physical factors that makes screening practical. For example, vibration, g force, bed density, and material shape all facilitate the rate or cut. Electrostatic forces can also hinder screening efficiency in way of water attraction causing sticking or plugging, or very dry material generate a charge that causes it to attract to the screen itself.

Screening by using geometrical patterns - bars, wire, circle, square or rectangle - is the most common method of size control in material processing. PAXAA offer screens for both wet and dry applications, and the screening media for optimum end product quality. Our equipment is easily adaptable for stationary crushing plants.
