Enhanced by resonance, one drive can produce two vibration movements. The screen box is accelerated approximately 2g's while the screen mats can receive up to 50g's. ... Inclined Vibrating Screen Sizes. The BIVITEC ® is available in size ranges from 800mm x 3m (3'x10') to 3000mm x 12m (10'x40') 1,2,3 and 4 deck vibrating screens ...
The dynamic model of a RR-based rectangular vibrating screen is considered as an initially stretched system of two equal masses connected by a linearly elastic spring. Due to the geometric nonlinearity longitudinal oscillations of the masses and lateral oscillations of the spring are coupled. Under certain conditions, when the masses are subjected by a self-equilibrated …
The article presents the results of research on the trajectory and amplitude values during the startup of a vibrating screen, depending on the set startup time. The research was conducted using a suspended vibrating screen with a segmental vibration trajectory, where vibration excitation was achieved through two vibratory motors directly attached to the screen …

The self-synchronizing far-resonant vibrating system of two eccentric rotors is widely used in petroleum, mining and food industries, and its motion stability is affected by material impact. However, the synchronous characteristics and stability of this kind of the system are studied rarely. Based on the background, a simplified mechanical model of the self …
Large-scale vibrating screens are widely used in minerals processing industry. One of main components in any vibrating screen is a set of springs supporting the main body of machine with sieving material inside. These springs are subjected to cyclic loading and fatigue. Changing of their stiffness and subsequent failures have influence on the sieving efficiency …
The bivi-TEC® Screen achieves these high forces by dynamically tensioning and relaxing the flexible screen mats using a dual-vibration principle. Enhanced by resonance, one drive can produce two vibration movements. The screen box is accelerated approximately 2g's while the screen mats can receive up to 50g's.
To obtain large exciting force for elliptical vibrating screen, a new three-exciter vibration system with two elastic coupling coaxial exciters is proposed. For studying the vibration characteristics and synchronization capability of the system, the Lagrange equation is firstly introduced to establish the dynamic model of the system. Then, the steady-state responses of …
Vibrating screen separator from Binder+Co. With the resonance screen, Binder+Co has impressively demonstrated sustainable in-house development. Developed by owner and managing director Dr. Heinz Sernetz in 1954, the resonance screen has been making an impression on customers of very different branches even in the 21st century.
Vibrating screen is the pivotal equipment of solid control in drilling mud purification system. With the continuous upgrading of rapid drilling technology, the conventional single-body vibrating screen with the same-frequency excitation is difficult to satisfy the needs of current drilling operations.
2. Dynamic model of vibrating screen . If we need to see response of vibrating screen as a whole body with included material mass, FEM or DEM models are not essential. Hence, dynamic model of vibrating screen is composed by assumption that screen vibrates as a rigid body. Calculating scheme for analysis of vibrating screen is assumed of
