Vibrating Screen screening method
1 rolling sieving
Screen surface is a tilted cylinder placement, work uniform rotation, the material in the tilt of therotor tube rolling, such as coal preparation plant early use of the cylindrical screen.
2-driven screening method
As the composition of the sieve of the rotating screen surface, the surface movement of materials through the sieve elements of the relay push along the screen for the first movement,such as the roller screen.
3 rock-type screening method
Screen surface can be placed level, can also be tilted placement, work screen surface in the plane reciprocating movement. To make the material and relative motion between the screen surface, such as the screen appear before the level of placement, the screen surface to dodifferential movement; screen tilt placement, the screen surface in the plane to do harmonicvibration. Material along the screen appear before the state step forward movement.
4 projectile-type screening method
Screen surface in the vertical longitudinal plane to do or quasi-harmonic vibration harmonicvibration. Linear trajectory of screen can also be round or oval. Material in the verticallongitudinal plane ejected forward, such as shaker.
Modern screening is mainly used projectile-type screening method, especially in raw materials"hard screen tablets," "hinder the grain," more, more, and other screening methods, has obvious advantages.
5 Slide the screening method
The material in the inclined stationary screen surface by its own weight down. This is the early use of the screening method, the screening efficiency is low, dealing with a small amount.
