FIELD: process engineering.
SUBSTANCE: invention relates to construction sand classifiers and may be used in mining, construction and agriculture. Proposed screen comprises frame mounted via dampers on foundation, screen and vibrator. Screen comprises screen box mounted via dampers on frame. Screen is arranged inside screen box. Rigid hammers spaced apart by clearance "e" are arranged on aforesaid frame and box to act in oscillating at phase angle ωt varying in the range of:
where n - 0, 1, 2, 3 is number of oscillations, tIM.S. is impact start moment. Vibrator may be arranged on either screen frame or screen box.
EFFECT: higher efficiency.
