Use a horizontal screen anywhere height is tight and you need accurate sizing at common cuts (20 mm / 10 mm / 4.75 mm), dry or wet. It’s a great match after cone/HSI stages for final splits and for rinsing before sand/classification.

Horizontal screen uses a gear-synchronized, triple-shaft mechanism that creates a high-energy elliptical (oval) motion. Elliptical motion improves stratification, reduces plugging, and maintains travel even on fine/wet work—ideal for accurate cuts in a low-profile machine.

• Crushed stone, gravel, and sand.
• Silica sand, quartz, and industrial minerals.
• Coal, iron ore, and limestone.
• Wet or dry material with equal efficiency.

• Screen media (mesh/PU/rubber).
• Bearings and shaft components.
• Springs or rubber suspensions.
• Side plate liners (in heavy-duty applications).
  Nesans provides readily available spares, reducing plant downtime.

• 2-deck: two finished products + overs (simple plants).
• 3-deck: the most common—e.g., 20 / 10 / 4.75 mm.
• 4-deck: adds a fine trim (e.g., 2.36 mm) or a bypass.

• Top deck: rubber or heavy PU for impact/abrasion; wire for max open area.
• Middle deck(s): PU for life on abrasive feeds or self-cleaning wire if pegging appears.
• Bottom deck / fine cuts: PU (tapered holes) or self-cleaning wire; consider slotted panels when near-size pegging is persistent.

Throughput depends on screen area, feed gradation, moisture, media, and settings. As a rule, size by area first, then tune stroke/speed/angle to stabilize bed depth. Use our model table (deck count and area per deck) as your starting point and we’ll validate with sizing curves for your material.

• Adjust stroke/RPM to increase stratification.
• Use PU/rubber decks to prevent blinding.
• In wet circuits, combine with Nesans sand washing systems for better efficiency.

Screen size depends on:

• Desired throughput (TPH).
• Feed size distribution.
• Number of products required (2-deck, 3-deck, 4-deck).

Typical signs include:

• Oversized material in fines.
• Inconsistent product gradation.
• Excessive vibration/noise.
• Frequent screen blinding or pegging.

• Daily checks: Bearing lubrication levels, screen media wear, abnormal vibrations/noise.
• Weekly checks: Tightening of bolts, inspection of drive components, checking stroke and RPM.
• Periodic maintenance: Bearing replacements, screen cloth change, spring inspection.

• Uneven product gradation: Usually caused by worn or blinded screen media.
• High vibration or noise: Can mean loose bolts, worn bearings, or cracked springs.
• Low efficiency: Often due to incorrect stroke/RPM settings or uneven feed.

• Better screening efficiency for fine materials.
• Flatter installation profile → suitable for plants with limited height.
• Consistent gradation → improves final product quality.
• Flexible stroke and speed adjustments → allows tuning for different feed materials.

• Horizontal Screen: Best for precision screening of smaller feed sizes.
• Inclined Screen: Best for high throughput, handling large feed sizes and sticky materials.
