Vibration frequency, screen inclination of the

For difficult-to-screen materials, the vibration direction angle should be taken as a large value. For easy-screen materials, the vibration direction angle should be small; in general, the vibration direction angle of the circular vibrating screen is 90°. The vibrating direction angle of the linear vibrating screen ranges from 30 to 60°, often 45°. This value not only has good performance for various screening but also

Vibratory Screens McLanahan

Screening is an important part of processing and is used to separate material according to its size. Material is typically fed to a single-, double- or triple-deck screen to make the required sizes. Screens can be considered the cashbox of the operation, because while crushers make the gradation, screens make the specification. Material must go through or over a specified size to end up in the right pile. Unlike the crushers, Vibratory Screens

Non-linear analysis of vibrating flip-flow screens

The vibration of the vibrating flip-flow screen in y direction can be neglected, because that the main and floating screen frames will vibrate synchronously in y direction when VFFS works, which cause little effect on the performance of the VFFS. Therefore, in this paper, the dynamics of the VFFS is studied only considering x direction. The machine is excited by a harmonic forcing of the form ...

Vibrating Screen Types Working Principle

linear vibrating screen is driven by double vibrating motors. When the two vibrating motors are rotating synchronously and reversely, the excitation force generated by the eccentric block offsets each other in the direction parallel to the axis of the motor, and overlaps into a resultant force in the direction perpendicular to the axis of the motor, so the motion track of the linear vibrating ...
