Abstract

The invention discloses a spiral vibrating type classifying screen. The spiral vibrating type classifying screen comprises a feeding hopper, a driving motor and a vibrating screen, and the vibrating screen is divided by a plurality of screen plates into a plurality of sub vibrating screens; a corresponding barrel is connected to the exterior of each sub vibrating screen, and one barrel, one screen plate, one sub vibrating screen and a corresponding center shaft form one screening compartment; and the hole diameters of screen holes of each screening compartments are the same, and the hole diameters of screen holes of the screening compartments are sequentially reduced from top to bottom. By means of the spiral vibrating type classifying screen, the spiral sub vibrating screens and the screen plates are adopted, screen holes are formed in the sub vibrating screens and the screen plates, and the sub vibrating screens and the screen plates are combined. The spiral sub vibrating screens conduct screening while conducting transporting, and screened materials are screened for the first time. When conveyed to the screen plates, the materials are screened for the second time, and the screened materials enter the next screening compartment. The sub vibrating screens and the screen plates both vibrate under the effects of the driving motor, double guarantees are achieved, the rate of leakage of wee materials is decreased, and the screening result is more exquisite.

Description

technical field [0001] The invention belongs to the field of ore classification, in particular to a spiral vibrating classifying screen. Background technique [0002] The vibrating screen works by using the reciprocating rotation vibration generated by the vibration of the vibrator. The upper rotating weight of the vibrator causes the screen surface to produce plane circular vibration, while the lower rotating weight causes the screen surface to produce conical rotary vibration. Its vibration track is a complex space curve. The projection of the curve on the horizontal plane is a circle, while the projection on the vertical plane is an ellipse. The vibration amplitude can be changed by adjusting the excitation force of the upper and lower rotating weights. And adjusting the spatial phase angle of the upper and lower weights can change the curve shape of the motion track of the screen surface and change the motion track of the material on the screen surface. [0003] The ...
