Description: This screen utilizes dual-body sub-resonance principle: they're linear motion of fixed screen body and activated floating frame vibration. They move with relative direction. In this process, the screen panel continues to expanding and contracting (800 times per minute) so that achieve a high acceleration rates (up to 50 g) and prevent the screen panel openings from plugging. Application: Coal plant sieving Power & port Coal & coal chemical industry Lignite & coke Iron ore & limestone Construction & demolition waste Sand & gravel Fertilizer & crop Features: Adjustable amplitude of floating screen High handling capacity High sieving efficiency Low installation height Low maintenance
