In the vibrating screen, vibration damping springs play the role of buffer and shock absorption. They absorb and dissipate vibration energy through elastic …
In coal mining, a new technical concept of using vibration wave to excite coal to improve gas extraction rate, i.e., the permeability enhancement technology of coal …
Researches focusing on shock and vibration in the deep mining environment have rapidly increased in recent years because of the exhaustion of shallow mineral resources and …
Exciter model. In practice, the mining vibrating screen has two exciters, which are bolted on the exciting beam (region A and region B). Since the exciter mass is much lower than …
August 9, 2024. Vibrating screens are complex assets used to separate materials into different particle sizes. They are widely used in mining, but are also found in processes …
This study, through the analysis of the system composition, the theoretical analysis of the vibration generation mechanism, and the empirical research of large …
The vibration of the flexible riser was tested in the depth-averaged reduced velocity (U r) range of 4.52–54.05. The experimental results indicate that only the in …
Exciter Mechanisms & Vibration Types. Exciters are the main vibration source of the screens. They generally comprise a housing, bearing, shaft and an eccentric mass. The vibration results from the rotation of the …
A box-type vibration exciter [1] can provide a reciprocating power source for a mine-used linear vibrating screen [2], and the helical gear pair is the key component. It plays an important role in …
The helical gear pair of a box-type vibration exciter of a mine-used linear vibrating screen is subjected to complex excitation and prone to broken tooth failures. At present,...
