This application provides a high-elasticity vibrating screening
system with variable frequency, variable amplitude, and variable trajectory, relating to the field of screening technology. The
system adopts a three-section screen box structure, including a first screening section, a second screening section, and a third screening section. The first screening section is driven by a first excitation unit with a
linear vibration trajectory. Its main function is to quickly spread and push the material, achieving preliminary screening and ensuring smooth forward movement. The second screening section is driven by a second excitation unit with a variable elliptical vibration trajectory. The second excitation unit can be adjusted to switch and adjust elliptical vibration trajectories with different parameters based on the looseness and activity of the material on the screen. This greatly adapts to the screening requirements of
complex materials such as sticky, wet, fine-grained, high-
moisture, and easily agglomerated materials, significantly improving screening efficiency and material
throughput. The third screening section is driven by a third excitation unit with a circular vibration trajectory. Its main function is to improve the final screening accuracy, overcome clogging, and promote screening.
