Flip-Flow Screen — The Critical Solution for Wet, Fine and Sticky Material Screening

The flip-flow screen is the “extreme condition processing module” within the SIMVIC size classification system, specifically designed to handle high-moisture, sticky, and fine materials that conventional screens cannot process. Based on a dual-mass near-resonance principle, the relative motion between the main frame and floating frame causes the elastic polyurethane screen to continuously stretch and contract, generating instantaneous acceleration up to 30g–50g, effectively dislodging clogged particles and enabling true self-cleaning screening.In the process flow, it is typically installed before fine sorting or advanced sensor-based separation, acting as a critical pre-treatment unit for difficult materials. By removing fine dirt, organic dust, and sticky contaminants, it prevents efficiency loss caused by clogging and protects downstream equipment such as optical sorting systems.From a system engineering perspective, its core value lies in “deep material reduction.” By removing inert components before sorting, it increases the metal concentration in the material stream, allowing downstream systems to process higher-value input, thereby improving recovery rates, operational efficiency, and overall plant profitability under complex conditions.
