Sloping chute, chute device, and method for classifying granular material

Abstract

The present invention provides a sloping chute and the like that can improve the classification efficiency of a vibrating screen. [Solution] The sloping chute has a supply port into which magnetic granular material is supplied, an outlet into which the granular material is discharged, and a connecting part that connects the supply port and the outlet. The connecting part is formed to be inclined downward from the supply port toward the outlet. The connecting part has a magnetic generating part that fixes the granular material with magnetic force. When granular material is supplied to the connecting part, the granular material is deposited at the connecting part. When further granular material is supplied, the supplied granular material comes into contact with the deposited granular material, causing the granular material to spread out in the width direction of the connecting part and be dispersed.
