Flip-Flow Vibrating Screens utilize elastic mesh screens made from polyurethane. These screens are designed to specifically handle problematic material such as those with excessive moisture content, a low density or that cannot be screened out with other technologies, such as rotary screens, conventional vibration screens, etc. They can also be changed simply and safely by using polyurethane wedges.
Screens are made of high density polyurethane panels. Panels are mounted in separate sections with screen sizes ranging from 13″ (330mm) to 16″ (400mm), depending on the product being screened and mesh opening needed. Each panel is fixed to both the main frame and the sub-resonant frame. By amplifying the vibration of the main frame of the screen in the sub-resonant frame and due to the polyurethane panels being fixed to both frames, screen panels bump together creating the “flip-flow” motion. This ensures that screened material will not stick or get caught in the screen.
Screen openings range from 0.03″ (0.8mm) to 2″ (50mm). Hardness and thickness of the polyurethane are changed according to the size of the screen and the requirements of the product being processed.
For applications that require unique separations, the Flip-Flow Vibrating Screen can be produced with other types of screen surfaces. These screen types can be either on the same machine or on a set of two different machines. Using two separate Flip-Flow Vibrating Screens means that users can combine different vibration frequencies and amplitudes as needed for each screening surface and product.
