Groove-vibrating and sieve-vibrating device and screening method

The invention discloses a groove-vibrating and sieve-vibrating device and a screening method. After dicumyl peroxide is crystallized and centrifuged, solid semi-wet powdery dicumyl peroxide is conveyed to a laboratory fluid bed dryer by the groove-vibrating and sieve-vibrating device for drying, and the dried high-purity dicumyl peroxide containing different particles and powder is conveyed to the next process to play a screening role in a conveying process.
