A vibratory sand screening machine separates particles by size using vibration and mesh screens. Raw sand is fed into the hopper, and the vibrating motor generates high-frequency oscillations, causing smaller particles to pass through the screen while larger debris is discharged. The machine’s amplitude and vibration frequency can be adjusted for different material grades.
– Vibrating Motor: Drives the screening motion (typical power: 0.5–3 kW).
– Screen Mesh: Available in 0.1–20 mm apertures for varied gradations.
– Springs/Dampers: Isolate vibrations to protect the chassis.
| Model | Capacity (t/h) | Screen Layers | Power (kW) | Weight (kg) |

| VSS-500 | 10–30 | 1–3 | 1.5 | 800 |
| VSS-1000 | 30–60 | 2–4 | 2.2 | 1,200 |
Q: How to reduce screen clogging?
A: Use anti-blocking mesh or ultrasonic cleaners for sticky materials.
Q: What maintenance is required?
A: Lubricate bearings every 200 hours; inspect screens weekly for wear.
A Malaysian quarry used a VSS-1000 to replace manual screening, increasing output by 40% and reducing oversize particles to <5%. The system processed 50 t/h of granite sand with a 3-layer screen configuration (mesh sizes: 5 mm, 10 mm, and 20 mm).
