technical field

The utility model relates to the technical field of vibrating screens, in particular to a double-layer linear vibrating screen with adjustable height and inclination.

Background technique

Vibrating screens are widely used in various industries due to their simple structure, stable amplitude and reliable operation. The production efficiency and screening level of the vibrating screen directly affect its development.

Its structure and working principle are more advanced. ,Reasonable.

The vibration parameters of the traditional vibrating screen are often difficult to adjust, which makes it impossible to maintain the best screening performance in the screening operation of various materials, and is not conducive to finding the best screening parameters of the vibrating screen in the experiment.

Since the two-layer sieve plates are often supported by a common spring damping system, the two-layer sieve plates have the same motion state under the action of the single excitation force synthesized by the dual motors, which is not conducive to the optimization of vibration parameters.
