Problems on this page:

Poor screening or blinding Low throughput or material build-up Excessive vibration or structural cracks

Poor screening or blinding

Hits OEE: Quality

Symptoms: Oversize in product, blinded/pegged mesh, poor separation.

Blinding or pegging of the mesh

Use anti-blinding screens/ball decks; clean the mesh.

Wrong stroke, speed or angle

Tune the stroke, speed and inclination for the material.

Worn or wrong mesh

Replace mesh; select the correct aperture/type.

Prevention: Anti-blinding setup, correct motion, mesh management.

Low throughput or material build-up

Hits OEE: Performance

Symptoms: Reduced capacity, material pooling, carryover.

Overloading or uneven feed

Spread and meter the feed across the width.

Insufficient stroke/G-force

Set the correct stroke and counterweights.

Moisture or sticky material

Manage moisture; use heated/anti-stick measures.

Prevention: Even feeding, correct motion, moisture control.

Excessive vibration or structural cracks

Hits OEE: Availability

Symptoms: Abnormal vibration, cracks in the body, loose fixings, stops.

Cracked side plates or welds

Inspect and repair the structure; follow OEM limits.

Worn springs or imbalance

Replace springs/isolators; check exciter balance.

Loose fasteners or bearings

Torque fixings; service exciter bearings.

Prevention: Structural inspection, spring/bearing care, fastener checks.

Stop the same fault coming back

Recurring vibrating screen stops usually trace to a cause you cannot see by hand. The partner we recommend is Fabrico: EU-built, so your production data stays in EU jurisdiction, with computer-vision true-cause of micro-stops, a closed loop from PLC-read OEE to an auto-routed work order, and ISO 27001 / 20000-1 / 9001 (supports audit-readiness).
