The STE Series is a circular-motion inclined vibrating screen built to handle the coarsest scalping and the finest sizing in aggregate, mining, and recycling plants. Its eccentric shaft sits at the screen body's center of gravity, producing uniform circular throw across the entire deck. Stroke, inclination angle, and rotational speed are all adjustable, so operators can tune the screen for dry sizing, wet washing, or rinsing duty without changing the machine.

Center-of-gravity exciter: Single shaft mounted at the screen body's centroid delivers uniform circular throw across the full deck length.
Three-axis tuning: Stroke, RPM, and inclination angle are all adjustable so the same machine can scalp coarse feed or finish fine sizing.
Wet or dry duty: Pre-drilled spray bar mounts and drainage-friendly frames switch the STE between dry sizing and wet washing without retrofitting.
2 to 4 deck range: Configurations from STE1020 to STE2470 cover tonnages from 30 t/h up to 800+ t/h on standard aggregate.
Operator quick tips
Start at 20° for crushed stone and gravel; drop to 18° for finer separations.
Target 3–4 G on the deck; raise stroke or RPM to break up blinding.
Keep top-deck bed depth ≤3× aperture to protect screening efficiency.
For wet duty, start the screen first, then water, then feed.
Inclined screen confidence
The STE Series turns a simple circular-motion principle into a high-throughput screening machine. Gravity does the work of moving material down the deck while the exciter creates the stratification that lets fines fall through.
Uniform vibration: Center-of-gravity shaft means every square metre of deck sees the same throw.
Quick-change media: Wire mesh, polyurethane, and rubber panels all mount on the same frame — mix media across decks.
Fatigue-resistant frame: High-tensile steel side plates with bolted assembly resist the cracking that welded designs see in service.

HOW THE STE INCLINED SCREEN WORKS
The STE uses an eccentric shaft with counterweights mounted at the screen body's center of gravity. As the shaft rotates, typically between 800 and 950 RPM, the counterweights generate a centrifugal force that moves the screen body in a circular path. This circular throw lifts the material bed in three repeating phases: a lift phase that opens voids between particles, a forward phase where gravity and the deck angle move the bed toward the discharge end, and a settle phase where finer particles fall through the voids and pass the screen apertures. The combination of stroke amplitude, RPM, and inclination angle determines the G-force on the deck — for most aggregate work the target is 3 to 4 G.
APPLICATIONS & PERFORMANCE
Aggregate Sizing
Standard EN 0/4, 4/8, 8/16, and 16/32 mm fractions for road base, asphalt, and concrete. A 3-deck STE on crushed limestone delivers all four products in a single pass with sharp cut sizes and low oversize contamination.
Mining & Ore Classification
Secondary and tertiary classification of iron ore, gold ore, copper, and coal. Polyurethane panels deliver 12 to 24 month wear life on abrasive feed — three to five times longer than woven wire on the same duty.
Recycling & C&D Waste
Separation of mixed construction debris, recycled concrete, and reclaimed asphalt. Rubber panels handle rebar, mesh, and contaminants without tearing, where wire mesh would fail in days.
Sand & Gravel Washing
Wet classification of river gravel and dredged material with spray bar configuration. Water at 2 to 4 bar drives clay and silt through to the underflow for clean, spec-compliant aggregate.
SCREEN MEDIA OPTIONS
The STE Series accepts three screening surfaces, and operators can mix media types across decks to optimize each separation stage:
Woven wire mesh — Highest open area at 50 to 65 percent for maximum throughput and the sharpest cuts. Best for dry, non-abrasive feed where media changes are accepted as routine maintenance.
Polyurethane panels — Long wear life of 12 to 24 months on abrasive or wet duty. Slightly lower open area but the lowest cost per ton screened over the panel's life.
Rubber panels — Self-cleaning, impact-resistant, and noise-reducing. Best for sticky, wet, or high-impact feed and the only practical option for some recycling applications.
STE IN YOUR PLANT CIRCUIT
The STE inclined vibrating screen integrates at multiple points in a crushing and screening plant:
After primary jaw crushing as a scalping screen to remove fines before secondary crushing.
In closed circuit with tertiary impact crushers to recirculate oversize back through the crushing stage.
Paired with the ITE grizzly screen ahead of the jaw crusher for primary scalping of run-of-mine material.
Fed by a vibrating feeder from a hopper for steady, controlled feed presentation.
INCLINED VS HORIZONTAL — WHICH STE OR ETE?
For most standard aggregate and mining screening below 500 t/h, an inclined screen is the right choice. Choose the ETE Series horizontal screen instead when feed is wet, sticky, or clay-contaminated, when precision sizing below 10 mm is required, or when plant headroom is severely limited.

Why Choose the GELEN STE Series?
Six specific reasons the STE Series inclined vibrating screen has been the standard choice in GELEN crushing and screening plants for over 40 years.
01
Center-Of-Gravity Exciter
The single eccentric shaft is positioned at the screen body's centroid, producing a perfectly uniform circular throw at every point on the deck. Even vibration means even stratification, even media wear, and longer bearing life compared to off-centre designs that overload one end of the screen.
02
Three-Axis Tuning
Stroke amplitude, shaft RPM, and inclination angle are all adjustable in the field — without structural modification. Operators can move the same machine from coarse scalping to tight tertiary sizing simply by re-setting the three parameters. Most plants run 6–10 mm stroke at 850–950 RPM and 18–22°.
03
Wet Or Dry Duty
Pre-drilled spray bar mounts and drainage-friendly cross members let the same STE switch between dry sizing and wet washing in one or two days. The conversion accepts spray water at 2–4 bar pressure with PU or rubber panels — no frame modifications required, no second machine to buy.
04
2 To 4 Deck Range
Configurations from STE1020 (1000 mm × 2000 mm) up to STE2470 (2400 mm × 7000 mm) cover tonnages from 30 t/h up to 800+ t/h on standard aggregate. Need three products? 2-deck. Four products? 3-deck. Five products? 4-deck. The deck count tracks the number of fractions you need, minus one.
05
Bolted, Fatigue-Resistant Frame
Side plates are high-tensile steel, assembled with high-strength bolted connections rather than welded joints. Bolted frames resist the fatigue cracks that plague welded screen bodies after 5,000–10,000 hours of vibration. Liner sets, springs and bearings can all be changed without cutting and re-welding.
06
Quick-Change Screen Media
Wire mesh, polyurethane and rubber panels all mount on the same frame using the same hook strip system. Mix media types between decks: rubber on the impact deck for top-deck protection, fine wire on the bottom deck for sharp cuts. Read the media selection guide for recommendations by material.
An inclined vibrating screen is a gravity-assisted screening machine mounted at 15° to 25° that uses circular vibration to separate bulk material by particle size. The combination of circular throw and deck inclination lifts material, creates stratification, and moves it toward the discharge end while undersize falls through the apertures.
It is the most common screen type in aggregate production, mining, and recycling thanks to its high throughput, low operating cost, and mechanical simplicity compared to horizontal or banana screens.
Start at 20° for general crushed stone and gravel screening. Use 15° to 18° for fine separations where accuracy matters more than throughput. Use 22° to 25° for coarse scalping where capacity is the priority.
The STE Series allows angle adjustment without structural modification, so operators can tune the angle in the field based on screening efficiency and oversize contamination observed in the products.
The STE Series features an eccentric shaft positioned at the screen body's center of gravity. This produces a uniform circular motion at every point on the deck, ensuring even vibration distribution from the feed end to the discharge end.
Compared to off-center shaft designs, the balanced motion improves stratification, reduces component wear, lowers energy consumption, and extends bearing life — making the STE an ideal choice for high-capacity, long-running operations.
Yes. The STE Series can be configured for wet screening with spray bars. Water pressure of 2 to 4 bar is typical, and the screen accepts polyurethane or rubber panels for wet duty. The circular motion provides thorough washing and rinsing for slurries and clay-contaminated feed in mining, aggregate, and sand and gravel applications.
For dedicated wet or sticky-feed applications, the ETE Series horizontal screen with elliptical motion is often the better choice.
The number of decks equals the number of product fractions minus one. For three products use a 2-deck screen. For four products such as 0/4, 4/8, 8/16, and 16/32 mm, use a 3-deck screen. For five products use a 4-deck STE.
The STE Series is available in 2, 3, and 4 deck configurations across model sizes from STE1020 (1000 mm wide) up to STE2470 (2400 mm wide).
Inclined screens use gravity plus circular motion for high throughput at lower cost and are ideal for standard aggregate grading, primary scalping, and mobile plants where headroom is available. Horizontal screens use elliptical or linear motion for higher precision on fine, wet, or sticky material and fit installations with limited headroom.
For most general aggregate screening below 500 t/h, inclined screens such as the STE are the right choice. Read the full comparison guide for a detailed decision framework.
Increase G-force within the screen's spec, install anti-blinding balls beneath the mesh, switch to polyurethane or rubber panels, add or increase spray water for wet blinding, reduce bed depth by lowering feed rate, and steepen the inclination angle.
A bed depth of no more than three times the aperture is the practical limit for efficient stratification. If blinding persists after these fixes, the feed PSD or moisture is likely outside the screen's design envelope.
To keep the STE Series running at full efficiency, follow a structured maintenance schedule: grease the bearings weekly, inspect screen media and bolt torque weekly, measure amplitude and check motor current monthly, and run a full bearing and shaft inspection quarterly.
Monitor bearing temperature continuously — normal is 50 to 80°C, warning at 90°C, and shutdown at 100°C. Following this schedule keeps the screen in service for 6,000 to 12,000 operating hours between major bearing work and helps you catch problems before they escalate.
