Why a small tear matters

A vibrating screen separates material through defined openings. A tear creates an uncontrolled opening, so oversized particles may reach the undersize outlet even when the machine appears to run normally. This article focuses on checking mesh condition rather than changing operating settings.

Prepare for inspection

Stop the feed and shut down the machine using the site procedure. Isolate energy sources and confirm that moving parts have stopped before opening guards or covers. Follow the equipment manual for access and handling; do not reach into an operating screen.

Inspect the mesh systematically

Remove loose material using a cleaning method compatible with the mesh and the product. Check the working surface, edges and attachment areas in good light. Look for broken wires, stretched openings, worn patches and separation from the frame. Compare suspect areas with an intact section. Avoid probing fine mesh with a sharp tool, which may create further damage.

Record the finding and check the product

Record the deck, damage location, material being processed and approximate operating hours. If damage could have affected separation, identify the potentially affected batch and follow the plant quality procedure for sampling or segregation. A visual inspection alone does not establish that the finished material meets its specification.

Return to service carefully

Use a replacement mesh with the specified opening, construction and mounting arrangement. Check seating and fastening against the manufacturer instructions, refit guards and complete the approved restart procedure. Verify the separated fractions after restart. For a vibrating screen inquiry, send Tianteng the mesh specification and photographs of the mounting arrangement so the required replacement can be discussed.
