A screen frame is the rigid circular or rectangular ring that holds the screen cloth in tension inside a vibratory separator, serving as both the mounting structure for the screen media and a structural component in the separator's stackable body assembly. Screen frames are precision-manufactured to fit specific separator models.
On round vibratory separators, screen frames are rings that stack between body sections, separated by gaskets and held together by clamp rings. For pre-tensioned screens, the woven wire cloth is bonded directly to the frame at the factory. For loose cloth installations, the cloth is stretched over the frame and secured with tensioning hardware. Each deck in a multi-deck separator has its own screen frame.
Why This Matters in Vibratory Screening
- Screen tension — The frame maintains uniform tension across the screen cloth, which is essential for consistent aperture size and accurate separation.
- Structural integrity — Frames carry the weight of the product on the screen plus the dynamic loads from vibration.
- OEM compatibility — Screen frames are designed to fit specific separator models. ScreenerKing frames are compatible with Sweco, Kason, Midwestern Industries, and other OEM separators.
- Ball deck mounting — Ball decks mount within or below the screen frame assembly.
