플라스틱 재활용 라인에 중앙축 드리움머신을 구매하는 것은 하나의 초기 결정에 달려 있습니다: 수평이나 수직 방향성. 이 선택은 바닥 공간, 용량 한도, 드리움 일관성, 유지보수 접근성, 자본 비용에 영향을 미칩니다 — 이 다섯 가지 요소 모두에서 때로는 2–3배로 변할 수 있습니다. 이 가이드는 공학적 차이, 실제 사양, 쪽자리 비교, 그리고 5단계 결정 프레임워크를 다룹니다. 이를 통해 첫 번째 시도에서 라인에 맞는 머신을 지정할 수 있습니다.

둘 다 원심 탈수기 같은 운영 원리를 기반으로 하고 있습니다 — 고속 랜드로터가 구멍이 뚫린 스크린 내에서 회전합니다. 랜드로터 축의 방향성은 거의 모든 다른 것을 결정합니다.
공학적 차이
수직 중앙축 드리움머신
랜드로터 축은 수직으로 위치합니다. 습한 파이프는 캔버스의 상단에서 공급되고, 랜드로터는 1,200–1,500 RPM으로 회전하며, 물은 스크린을 통해 방사적으로 빠져나가고, 드리움 파이프는 측면이나 하단 포트에서 배출됩니다. 재료는 캔버스 내에서 약 2–5초 동안 머무릅니다.
축적 면적은 작습니다 — 일반적으로 400–800 kg/h 단위의 1.0 × 1.5 m입니다 — 그리고 머신은 자체 기반 위에 자체적으로 배치됩니다. 스크린과 랜드로터 점검에 대한 내부 접근은 간단합니다: 상단 캔버스를 들어 올리면 구성 요소가 보입니다. 컨베이어나 공급 팔레트가 정렬되는 것은 필요하지 않습니다.
수평 중앙축 드리움머신
랜드로터 축은 더 긴 스크린 드럼 내에서 수평으로 운행됩니다 (일반적으로 1.5–2.5 m 길이). 습한 파이프는 한쪽에서 공급되고, 랜드로터에 장착된 팔레트나 스크류 날이 랜드로터가 회전하면서 재료를 스크린에 따라 이동시킵니다. 드리움 재료는 한쪽에서 배출됩니다. 머무리 시간은 더 길며 — 일반적으로 5–10초 — 더 긴 이동 경로는 출력 스트림의 더 일관된 습도를 생성합니다.
축적 면적은 더 큽니다 (일반적으로 1,500 kg/h 단위의 2.5 × 1.5 m입니다), 하지만 바닥 면적 당 처리량은 수직 단위와 비교해 유사합니다. 유지보수는 끝 캔버스를 제거하고 랜드로터를 밀어 내는 것으로 이루어지며 — 수직 단위보다 더 복잡하지만 여전히 두 기술자가 1–2시간 동안 할 수 있는 작업입니다.

핵심 요약: Vertical wins on cost, footprint, and maintenance simplicity. Horizontal wins on throughput, output uniformity, and energy efficiency per ton at scale. The crossover point is around 1,000 kg/h — below it, vertical is almost always the right call; above it, horizontal almost always.
Where Each Fits in the Recycling Line
PET Bottle Flake Line
For PET bottle recycling above 1 ton/h, horizontal centrifugal dewatering is standard. The longer screen contact removes label residue and fines along with water, and the lower rotor speed reduces flake breakage on PET (which is more brittle than HDPE or PP). Below 800 kg/h, a vertical machine is sufficient — common in smaller PET reclaim operations and pilot lines. Some high-spec PET lines run a vertical unit as a polishing stage ~ 후에 a horizontal primary, achieving sub-2% moisture before the 열 건조기.
HDPE / PP Rigid Regrind
For washed HDPE crate or PP drum regrind, both orientations work well. The decision is purely throughput and budget: vertical for sub-1 ton/h operations, horizontal for higher capacities. HDPE and PP tolerate higher rotor speeds without breakage, so vertical machines at 1,500 RPM perform efficiently on these materials.
PE / PP Film Lines
Film is a different problem. Standard rigid-flake centrifugal dewatering machines — vertical or horizontal — are not optimized for film, which wraps around rotor paddles. For film recycling, use a 고속 플라스틱 필름 원심 탈수기 (anti-wrap rotor design) or a 필름 압착기 instead. These are purpose-built for flexible material.
Mixed Rigid Waste / Pilot Lines
For research, pilot, or low-throughput operations processing mixed rigid plastics, vertical centrifugal dewatering machines are the practical default. Capital cost is 2–3× lower, footprint fits in a corner of a workshop, and a single operator can run and maintain the unit. Most equipment manufacturers (including Energycle) offer entry-level vertical units at 22–37 kW for under $12,000 USD.
5-Step Decision Framework
Step 1: Define Your Throughput
Identify your peak hourly material flow in kg/h, not your daily tonnage divided by 24 hours. Recycling lines run in batches with cleanup gaps, so peak feed rate is typically 1.5–2× the daily-average rate. If your line processes 10 tons over an 8-hour shift, your peak is approximately 1,500–1,800 kg/h — choose horizontal.
Step 2: Audit Your Floor Space and Headroom
Vertical units need 2.5–3.0 m of vertical clearance for the chamber height plus crane access for screen removal. Horizontal units need 2.5–4.5 m of length plus working space at both ends. Measure actual available footprint 그리고 headroom — vertical machines fail to install in low-ceiling buildings even when the floor footprint fits.
Step 3: Specify Output Moisture Requirement
If your downstream process is direct extrusion of HDPE or PP, 3–5% moisture is acceptable — vertical handles this. If your downstream is PET pelletizing or any application requiring sub-2% moisture, you will need a horizontal centrifugal dewatering machine followed by a 열 건조기. Read our centrifugal vs thermal drying energy comparison for the energy math behind this decision.
Step 4: Calculate Total Cost of Ownership
Vertical capital cost is lower (sometimes by half), but horizontal energy cost per ton is also lower at scale. For a line running 4,000 hours/year:
- Vertical unit (45 kW, 800 kg/h): $12,000 capital + ~$7,200/year energy at $0.10/kWh = $19,200 first-year, $7,200/year ongoing
- Horizontal unit (55 kW, 1,500 kg/h): $25,000 capital + ~$8,800/year energy = $33,800 first-year, $8,800/year ongoing
For the same throughput requirement, the horizontal unit pays back its higher capital cost over 4–6 years through lower per-ton energy and lower labor cost (one operator handles 2× the throughput).
Step 5: Verify Maintenance and Service Access
Vertical: top cover lifts, screen and rotor lift out — 30 minutes for screen change, no tools beyond a wrench. Horizontal: end covers unbolt, rotor slides out on rails — 1–2 hours for screen change, requires two technicians and a lift point. If your maintenance team is small or external, vertical is easier. If you have an in-house mechanical team and value uptime over service simplicity, horizontal is fine.
Common Misconceptions
“Vertical is always cheaper to run”
Not above 1,000 kg/h. At higher throughput, horizontal is more energy-efficient per ton because the longer residence time achieves the same dewatering with a lower-speed rotor (lower kW per kg processed). Vertical units pay an energy penalty when pushed near their throughput ceiling.
“Horizontal handles all materials better”
Not film. Both orientations struggle with film unless purpose-designed for it. For film, use an anti-wrap film centrifugal dewatering machine or a screw-press film squeezer.
“Vertical units cannot reach low moisture”
They can — adequate for HDPE/PP direct extrusion (3–5% target). They cannot reach sub-2% in a single pass; that requires either a horizontal unit or a vertical primary plus a thermal finishing stage.
자주 묻는 질문
horizonital LJ vertical LJ centrifugal dewatering machineLJ 간의 차이점은 무엇인가요?
The difference is rotor shaft orientation, which affects throughput, residence time, and output uniformity. Vertical units have a vertical rotor with 2–5 second residence time, suit 200–1,000 kg/h throughput, and have a compact footprint. Horizontal units have a horizontal rotor with paddles that convey material along a longer screen — 5–10 second residence time, 800–3,500 kg/h capacity, more uniform dewatering, but larger footprint and higher capital cost.
PET 병 파이브 레이싱에 어떤 것이 더 좋을까요?
For PET bottle flake lines above 1 ton/h, horizontal centrifugal dewatering is the industry standard. The longer screen contact removes label fragments and fines, and the lower rotor speed reduces flake breakage. Below 800 kg/h, a vertical centrifugal dewatering machine is sufficient. High-spec PET lines often combine both: horizontal primary plus vertical polishing.
가로와 세로 센트리푸스 드리웨터 기계 비용은 얼마인가요?
Vertical centrifugal dewatering machines typically cost $8,000–$18,000 USD for 22–45 kW units (200–1,000 kg/h capacity). Horizontal centrifugal dewatering machines cost $15,000–$45,000 USD for 37–90 kW units (800–3,500 kg/h capacity). At the same throughput, horizontal units cost 50–80% more upfront but deliver 10–20% lower energy cost per ton, paying back the difference within 4–6 years for continuous-operation lines.
PET 라인에서 직립형 중앙축 건조기 사용이 가능한가요?
It is possible by paralleling two or three vertical units, but rarely the cost-effective choice above 1.5 tons/h. A single horizontal centrifugal dewatering machine at 2,000 kg/h has lower capital cost than three 700 kg/h vertical units in parallel, plus simpler control logic and one maintenance schedule. Horizontal becomes the standard above 1 ton/h for this reason.
각 유형의 고정형 플라스틱 파이프에 대해 어떤 습도 수준을 달성할 수 있습니까?
Vertical units typically achieve 3–5% outlet moisture on washed PET, HDPE, or PP flakes in a single pass. Horizontal units achieve 2–4% moisture under similar conditions, mostly because of longer screen contact time. Both require a downstream 열 건조기 to reach sub-1% moisture for PET pelletizing or extrusion-grade applications.
결론
The horizontal vs vertical centrifugal dewatering machine choice is determined by throughput, output uniformity requirement, and total cost of ownership — not by personal preference or supplier preference. Below 1 ton/h, vertical is almost always the right answer. Above 1 ton/h, horizontal is almost always the right answer. PET bottle flake lines and applications requiring uniform sub-3% moisture push the decision toward horizontal earlier.
