For traditional screening rotary vibrating screen can also sieve liquid materials, but through many years practical experience, its effect is not good. Therefore at present have many types for sieving liquid, these situation as following:

1.High frequency vibrating screen: Mainly adopts high frequency motor, slurry enters screen surface, due to higher vibration frequency, can rapidly sieve out liquid, achieve solid-liquid separation.

2.Edge type rotary vibration screen: It is the ordinary rotary vibrating screen, but for avoiding slurry leakage in sieving, usually increase the height of upper frame, make this edge type, then motor uses the ordinary vibration motor. Mainly used in ceramics, pigment, paint, waste water, fruit juice, etc.

3.450 Filter screen: Mainly used for sieving materials with small filtration capacity and easy to sieve, more used in home work, such as: soy milk, etc.

Different materials choose the different sieving equipment to complete this screening progress.
