If you have ever had to replace a wire mesh screen because it snapped at the support beam, you know what a headache it is—reducing productivity and driving up costs. Operators often try to fix the issue by tightening bolts or inserting thin metal shims, only to find that—after just a few days of high-frequency vibration—the screen still cracks or breaks at the point of contact with the beam. The introduction of U-shaped rubber strips offers a simple, low-cost solution that completely eliminates this risk of failure.
Eliminates Hard Metal-to-Metal Friction
Without any cushioning, the steel wire screen sits directly on bare steel support beams, and thousands of high-frequency vibration cycles per minute create nonstop grinding friction between the two metal surfaces. This wears thin the screen wires at the contact line in days, creating a weak spot that snaps the second a heavy ore chunk lands on it. The U-shaped rubber damping strip clips right over the top of the support beam, creating a full soft rubber buffer that completely removes metal-to-metal contact, so no grinding wear can ever happen to the screen wires.
Absorbs Vibration Shock to Stop Fatigue Breakage
Beyond cutting friction, the U-shaped rubber damping strip absorbs the sharp, concentrated impact that travels from the vibrating beam straight up into the screen wires. Without this cushion, the repeated sharp shocks create tiny invisible fatigue cracks in the steel wires right at the beam edge, which spread until the whole screen tears apart. The flexible U-shaped rubber spreads that impact force evenly across the whole contact area, drastically slowing down metal fatigue and stopping those unexpected mid-shift screen breaks.
Field data from quarry operations indicates that installing U-shaped rubber damping strips on all screen support beams extends the average service life of steel wire screens by three to four times. A crushed stone plant reported that, following this upgrade, its monthly screen replacement costs were cut by more than half, and there were no further instances of accidental screen breakage along the beam lines. This compact, low-cost accessory offers a highly efficient solution for reducing screen wear and minimizing unplanned downtime across various operational sites.
