에이 플라스틱 폐기물 파쇄기 is a heavy-duty machine that tears, cuts, or crushes plastic waste into uniform particles for downstream sorting, washing, or recycling. If you run a Material Recovery Facility (MRF), a plastic recycling plant, or an industrial waste operation, choosing the wrong shredder — or placing it incorrectly in your line — will bottleneck every process after it.
본 가이드는 조달 및 운영 관리자들이 반드시 알아야 할 기계 유형, 사전 분류 요구사항, 처리량 계횈, MRF/MSW 처리 라인과의 연동 방안, 그리고 실제 시장 가격 기준에 대한 내용을 담고 있습니다.
What Is a Plastic Waste Shredder?
제안드리는 번역은 다음과 같습니다. “플라스틱 폐기물 분쇄기는 병, 드럼통, 파이프, 필름, 팔레트와 같은 플라스틱 제품들을 일관된 크기의 조각으로 분해하는 데 사용되는 산업용 크기 축소 장비로, 일반적으로 30–150 mm 크기의 조갈들을 생산합니다.
플라스틱 폐기물 분쇄기는 고속으로 가동되며 사전 분쇄된 원료를 사용해야 합니다. 그러나 그라인더와는 달리 low-speed, high-torque cutting action — typically 20–80 RPM — that handles bulky, contaminated, or mixed feed without pre-cutting. This makes them the entry point for both municipal solid waste (MSW) streams and industrial post-production scrap.

The Challenge of Processing Mixed Plastic Waste
당연. Contamination, variable density, and incompatible polymer types According to Reworld의 보고에 따.
Three specific challenges drive most operational headaches:
- Density variation: A single feed batch may contain lightweight LDPE film (density ~0.92 g/cm³) alongside rigid HDPE drums (density ~0.95 g/cm³) and heavy PVC pipe (density ~1.4 g/cm³). The shredder must handle all without jamming.
- Contamination load: Soil, food residue, metal fasteners, and glass shards inside plastic waste accelerate blade wear. Budget for blade replacement at 800–1,500 operating hours for heavily contaminated streams.
- Oversized or tangled materials: 고객님께서 문의하신 기계는 플라스틱 파이프, 스트랩 밴드, 그리고 축 주위에 감긴 더미 형태의 필름을 처리할 수 있는 장비입니다. automatic reverse rotation 안내해 드리겺습니다. 해당 기능은 대부분의 트윈 샤프트형 기계 모델에 기본으로 탑재되는 표준 사양입니다.
Pre-Sorting Requirements Before Shredding
추가 정보가 필요합니다.</｜＜hy-Assistant＞ pre-sorting stage protects your shredder and extends its service life.
Minimum pre-sort steps for MRF applications:
- Bag breaking: 당연.
- Coarse trommel screening: A rotating drum screen (typically 80–150 mm mesh) removes fines, organics, and undersized material that don’t need shredding — reducing the load on the shredder by 15–30%.
- Ferrous metal removal: Install an 오버밴드 자기 분리기 단순.
- Manual pick station: A human inspection point (or AI-assisted vision system) removes hazardous items — gas cylinders, batteries, large glass — that could cause catastrophic machine failure.
을 위한 industrial post-production plastic scrap, pre-sorting requirements are simpler: separate by resin type (PET vs. HDPE vs. PP) if purity of the shredded output matters. If the output feeds an RDF line, mixed resins are acceptable.
Throughput Planning: How to Calculate Real Output
Manufacturer-rated capacity figures are almost always higher than real-world output. A shredder rated at 1,000 kg/h on clean HDPE flakes will deliver far less on contaminated mixed municipal plastics.
Use this two-step adjustment formula to calculate realistic throughput:
Step 1 — Material Hardness Index (MHI) adjustment: Real output = Rated capacity × MHI
Common MHI values:
- Clean PET/HDPE bottles: 0.80–0.90
- Mixed rigid plastics: 0.60–0.70
- Mixed MSW plastics (contaminated): 0.45–0.60
Step 2 — System Efficiency Coefficient (SEC) adjustment: Effective output = Step 1 result × SEC (typically 0.70–0.85 for continuous operations)
Example: A shredder rated at 2,000 kg/h on mixed rigid plastics (MHI = 0.65) operating with a SEC of 0.75:
- Step 1: 2,000 × 0.65 = 1,300 kg/h
- Step 2: 1,300 × 0.75 = 975 kg/h real output
This means a plant planning to process 15 tonnes/day (two 8-hour shifts) actually needs a machine rated at approximately 2,000 kg/h minimum — not 1,000 kg/h. Always size up, not down. An undersized shredder bottlenecks the entire line; an oversized one adds only marginal cost per tonne.
Plastic Waste Shredder in MRF and MSW Sorting Lines
에이 plastic waste shredder machine sits at the pre-treatment stage of a Material Recovery Facility — before optical sorters, air classifiers, and density separators. Its job is not to separate plastics; it is to reduce particle size so that separation equipment can work accurately.
Typical MRF Integration Sequence
- Receiving hopper → raw mixed waste input
- Bag breaker + trommel screen → pre-conditioning
- Plastic waste shredder → size reduction to 50–150 mm
- Overband magnet → ferrous metal removal
- 에디커런트 분리기 → non-ferrous metal removal
- Air classifier / ballistic separator → light vs. heavy fraction separation
- NIR optical sorter → PET / HDPE / PP / PVC identification and ejection
- Baler or conveyor to downstream → baled plastic fractions to recycler
The shredder’s output size directly determines the accuracy of every separation stage that follows. A NIR optical sorter, for example, performs best on particles between 40–120 mm — feed that is too large or too small reduces sort purity.
Integration with Energycle’s plastic shredders
Energycle’s plastic waste shredder line is designed for direct integration with downstream MRF sorting equipment. The shredders include PLC control and adjustable output screens, allowing operators to dial in particle size to match the requirements of their NIR sorters or washing lines. For plants processing rigid containers, the 경질 플라스틱 파쇄기 series handles HDPE, PVC, and ABS at industrial scale.
Plastic Waste Shredder Cost: What to Budget in 2026
According to Energycle’s pricing data, plastic waste shredder machines range from $10,000 to $80,000 depending on shaft configuration, rotor width, blade material, and motor power.
| 기계 유형 | 용량 | 가격 범위 (USD) | Best Application |
|---|---|---|---|
| 단축 파쇄기 | 200–2,000 kg/h | $10,000 – $40,000 | Film, bottles, light rigid |
| 이중축 파쇄기 | 500–5,000 kg/h | $25,000 – $80,000 | Rigid, thick-walled, drums |
| Four-shaft shredder | 1,000–10,000+ kg/h | $60,000 – $250,000+ | MSW, MRF, RDF production |
| Starter system (shredder + granulator + conveyor) | 100–500 kg/h | $15,000 – $60,000 | Small recyclers, pilot lines |
Key cost drivers beyond the machine price:
- Blade material: D2 tool steel costs more upfront but lasts 2–3× longer than standard carbon steel blades on abrasive feeds.
- Motor power: Every 15 kW of added motor power adds roughly $3,000–$8,000 to machine cost.
- Hydraulic pusher: An integrated pusher adds $5,000–$15,000 but is essential for low-bulk-density materials like film bales.
- 설치 및 커미셔닝: Budget 10–15% of machine cost for on-site installation, especially for MRF integration with conveyor systems.

자주 묻는 질문
What is a plastic waste shredder?
A plastic waste shredder is an industrial machine that uses low-speed, high-torque rotating blades to tear and cut plastic waste into uniform fragments, typically 30–150 mm, for recycling or waste processing. It handles all plastic types — from thin film to rigid drums — and serves as the primary size-reduction step in MRF and recycling plant workflows.
Can a shredder handle mixed plastic waste?
Yes, a double-shaft or four-shaft plastic waste shredder machine can process mixed plastic waste streams, including contaminated and heterogeneous municipal plastic waste. However, effective pre-sorting — bag breaking, magnetic metal removal, and coarse trommel screening — is required beforehand to protect the blades and maintain consistent throughput. A contaminated mixed stream reduces effective capacity by 40–55% compared to clean single-resin input.
How much does a plastic waste shredder cost?
Plastic waste shredder prices range from $10,000 for a small single-shaft unit to over $250,000 for a high-capacity four-shaft industrial system. According to Energycle’s 2026 pricing data, the most common range for a production-ready double-shaft shredder for MRF or recycling plant use is $25,000–$80,000, with total installed system cost (including conveyors and controls) typically 25–40% higher than the machine price alone.
