The vibrating screen is a key equipment for separating granular materials based on size and is often used extensively in mining, building, agriculture, metallurgy, drilling, and other industries. 1 The vibrating trajectory is the most important factor of a vibrating screen. So researchers never stop to explore the appropriate trajectories of the screen.
A new concept of banana vibrating screen which has the same effect as traditional banana vibrating screen in a new way was put forward. The dynamic model of vibrating screen was established and its working principle was analyzed when the action line of the exciting force did not act through the centroid of screen box. Moreover, the dynamic differential equations of …
The enlargement of structure of vibrating screen will lead to the increase of vibration mass and exciting force. Dynamic load on the vibrating screen is also increased which will lead to a greater deformation, tear of the side plate, fracture of the crossbeam, and thus affects the service life of the vibrating screen seriously [1-3] .
The dynamic model with six degrees of freedom of the vibrating screen is established based on the Lagrange method, and modal parameters (natural frequencies and modes of vibration) of the rigid body are obtained. Dynamic characteristic and reliability of the vibrating screen are important indicators of large vibrating screen. Considering the influence of coupling motion of each …
In addition to classifying bulk material, vibration screens are commonly used in dewatering.
