The vibrator 11 is used for driving four corners of the first screening plate 2 and the second screening plate 3 to vibrate, so that powder falling on the first screening plate 2 and the second screening plate 3 is screened by slowly displacing from the middle to two sides.

With screening board one 2, screening board two 3 sets to curved arch structure, compound miropowder falls on screening board one 2 after 4 entering from the pan feeding mouth in proper order, the intermediate position of screening board two 3, under the vibration of vibrator 11, compound miropowder is towards screening board one 2 from the centre, two 3 both sides displacements of screening board, compound miropowder after the screening is through screening board one 2, the hole of screening board two 3, impurity is from screening board one 2, two 3 both sides roll-off discharge gate one 5 and discharge gate two 6 of screening board, make impurity difficult accumulation on the screening board, prevent to block up the screening board, and towards screening board one 2, the both sides synchronous displacement of screening board two 3, screening efficiency is higher.
