Cam vibration-based screen equipment for processing black tea comprises a housing. A first-grade screen mesh and a second-trade screen mesh are disposed in the housing; the first and second-grade screen meshes incline toward a bottom left direction; the first-grade screen mesh is arranged over the second-grade screen mesh; the diameter of a mesh of the first-grade mesh is greater than the diameterof a mesh of the second-grade mesh; a lower end of the first-grade screen mesh is correspondingly provided with a first-grade outlet and a lower end of the second-grade screen mesh is correspondinglyprovided with a second-grade outlet; the internal top of the housing communicates with a dust collector arranged outside the housing via an air pipe; a pedestal is arranged under the housing; a firstgroove is formed in the pedestal; a vibrating device is disposed in the first groove; the vibrating device has a rubber pad; the rubber pad is fixedly connected to the bottom of the housing; and therubber pad is also placed in the first groove. The beneficial effects are that dust in the housing can be sucked out by the dust collector, so body health of an operator can be effectively protected;and the housing vibrates due to the vibrating device, so black tea can be effectively screened.
