Inclined vs Horizontal vs Banana Screen — Which Do You Need?

The Three Screen Types in 60 Seconds

Inclined screen — the workhorse

An inclined vibrating screen sits at 15° to 25° and uses a single shaft with eccentric counterweights to generate a circular motion. Gravity does most of the work moving material down the deck. Inclined screens are mechanically simple, low-cost, and high-throughput. The GELEN STE Series is a typical two-bearing center-of-gravity inclined screen.

Best at: coarse scalping, standard aggregate sizing, mobile plants, lowest CAPEX. Weakness: needs headroom (the deck is steep), and accuracy drops on fine cuts below 10 mm.

Horizontal screen — the precision tool

A horizontal screen sits at 0° to 10° and uses two or three shafts to generate an elliptical or linear motion. Without gravity helping move the bed, the motion has to do all the work — which means the operator can tune retention time and screening accuracy independently. The GELEN ETE Series uses a triple-shaft elliptical drive.

Best at: fine sizing, sticky and wet feed, low-headroom installations, mobile plants. Weakness: higher CAPEX, more mechanical complexity, lower throughput per square metre at coarse cuts.

Banana screen — the high-capacity finisher

A banana screen uses multiple deck slopes — typically 30°-40° at the feed end dropping progressively to 0°-10° at the discharge end. The steep upper section accelerates the bed for fast stratification; the shallower lower section gives fine particles enough retention time to drop through. The result: 1.5x to 2x the capacity of an inclined or horizontal screen of the same size on coarse-to-fine sizing duties.

Best at: very high tonnage, full-spectrum sizing in one machine, dewatering. Weakness: highest CAPEX, complex deck construction, requires the most headroom, and the steep feed-end angle is rough on screen media.

Decision Flowchart — 5 Questions

Answer these five questions in order. The first decisive answer wins.

• 1. Is your feed wet, sticky, or clay-contaminated? → If yes, choose horizontal (ETE Series). The elliptical motion clears clay and prevents blinding far better than circular motion. Inclined screens fight wet feed; the deck angle alone is not enough.
• 2. Do you need precision sizing below 10 mm? → If yes, choose horizontal. The longer retention time on the flat deck gives fine particles more chances to find an opening. Inclined screens work for fines but at lower efficiency.
• 3. Is plant headroom severely limited? → If yes, choose horizontal. The low deck angle and compact frame fit retrofit and mobile installations where inclined screens cannot.
• 4. Do you need maximum throughput on coarse material above 500 t/h? → If yes, choose banana (or two inclined screens in parallel). Banana screens have the highest capacity per m² for coarse-to-fine duties.
• 5. Is budget the main constraint, or is the application standard aggregate sizing? → If yes (or you reached this question), choose inclined (STE Series). Lowest CAPEX, lowest OPEX, simplest mechanical design. Right answer for 80% of standard plants.

When Inclined Beats Horizontal — Practical Cases

• Primary scalping after a jaw crusher. The high-impact, large-feed environment crushes flimsy horizontal frames. Inclined screens handle 200+ mm feed cleanly. For run-of-mine scalping, pair an inclined STE with a grizzly ITE Series ahead of the jaw.
• Standard aggregate grading (0/4, 4/8, 8/16, 16/32 mm). A 3-deck STE inclined handles this efficiently at lower cost than a 3-deck horizontal screen of the same width.
• Mobile and portable plants. Inclined screens are mechanically simpler, lighter, and cheaper to mount on a tracked or wheeled chassis. Most mobile crushers and screeners use inclined screens.
• Budget-sensitive operations. Lower CAPEX, lower OPEX, simpler bearings and exciter. The total ownership cost over 10 years is typically 30–40% lower than a horizontal screen of the same capacity.

When Horizontal Beats Inclined

• Wet sand, dewatering duty, slurries. Horizontal screens with elliptical motion clear water and clay much faster than inclined circular motion. Standard for sand & gravel washing.
• Coal preparation, sticky ores. Coal often comes in with 8–15% moisture and clay contamination. The horizontal ETE handles this without blinding.
• Recycling streams with mixed flaky material. Construction waste, tire chips, and shredded materials pack and peg on inclined wire mesh. Horizontal elliptical motion keeps the bed loose.
• Tertiary fine-product sizing. If you need to make a clean 4 mm or 2 mm cut, horizontal screening efficiency on the bottom deck is significantly higher than inclined.
• Low-headroom installations. Retrofit projects, basement plants, mobile plants. Horizontal screens are typically 20–30% shorter from feed lip to discharge than an inclined screen of the same area.

When Banana Beats Both

• Single-screen sizing of 500+ t/h with full PSD range. A single banana can do what would take two inclined screens in parallel. The trade-off is 1.5–2x the CAPEX of a single inclined.
• Iron ore, coal, and other high-tonnage minerals. Where the operating cost per ton drives the economic case, banana screens win on long enough run hours to amortize the CAPEX.
• Pre-dewatering before centrifuges or filters. Banana screens combine high-capacity screening with effective dewatering on the steeper upper deck.

Banana screens are not usually the right choice for: aggregate plants under 400 t/h, mobile plants, or any installation that prioritizes simplicity and low CAPEX over peak capacity.

Cost Comparison — CAPEX and OPEX

Indicative figures for a 250 t/h, 3-deck screen on standard aggregate. Actual prices vary widely by manufacturer, region, and specification.

For a typical aggregate plant, the inclined screen wins on total cost of ownership unless the application specifically needs horizontal or banana capabilities.

Frequently Asked Questions

• Can one machine do both inclined and horizontal duty? No. The drive geometry, frame angle, and deck design are fundamentally different. The same body cannot be both.
• What about linear motion screens? Linear motion is a sub-type of horizontal — twin shafts in opposed phase generate a straight-line throw. Linear screens are great for dewatering and fine sizing but have higher mechanical loads on bearings than triple-shaft elliptical designs like the ETE.
• Is a banana screen the same as a multi-slope screen? Yes — banana screens are sometimes called multi-slope or compound-deck screens. The "banana" name comes from the curved deck profile.
• What about high-frequency screens? High-frequency screens (1,500–3,600 RPM) are a separate category for very fine sizing below 1 mm. They are usually horizontal with very small strokes and high G-force.
• Can I retrofit a horizontal screen in place of an inclined one? Sometimes, but plan for new feed and discharge chutes (different geometry) and check that your support structure can handle the different vibration pattern.
