The angle between the screen panel at n 1 and the x-direction is θ 1 + β 1. The normal relative velocity between screen panel and particle at the contact position is: (31) v r = v 1 sin θ 1-v. The coefficient of restitution is e, the velocity of screen panel is considered to remain the same after the collision.
Linear vibrating screens and circular vibrating screens are both types of vibrating screens used in various industries for screening and grading of materials. While they serve similar purposes, they have distinct differences in terms of their design, motion pattern, and applications. The differences between linear and circular vibrating screens
9 differences between linear and circular vibrating screen. Vibrating screens have a wide variety of types according to the movement track of materials, such as, circular vibrating screens, linear vibrating screens and fine screening machine, and these three are the most commonly used types in daily production. Classification of vibrating screen
At present, there are mainly two kinds of vibrating screens commonly used on the market: linear vibrating screen and circular vibrating screen. They mainly have the following …
During operation, blockages in the screen are almost entirely prevented and the material is dispersed to enable fine grain separation. Conventional screens are usually unable to deliver this performance – this is where JOEST Flip-Flow Screens from the OSCILLA Family are used. Typical cross cuts range between 0,5 and 40 mm.

3.Blocking phenomenon. The material of the circular vibrating screen moves in a parabolic circular trajectory on the screen surface, so that the material is dispersed as much as possible to improve the bounce force of the material, and the material stuck in the screen hole can also jump out, reducing the hole blocking phenomenon.

There are several differences between conventional circular or linear motion screens and the Hein, Lehmann Liwell 'flip-flop' screen. The Liwell screen has two screen cases to which crossbeams are attached alternately to each. Screen mats are attached to these crossbeams and then alternately flexed and relaxed 60 times per second.
