플라스틱 플레이크용 원심 탈수기

주로 PET 병 플라스틱 파편과 같은 단단한 플라스틱 파편, 단단한 HDPE 또는 PP 재생재료에 특화되어 있습니다. 소프트 PE 또는 PP 필름은 다른 드레인링 접근 방식, 예를 들어 필름 압착기.

단단한 플레이크의 경우, 안정적인 작동 조건에서 출구 수분 함량은 일반적으로 2~3% 정도입니다. 실제 성능은 입구 수분 함량, 플레이크 크기, 로터 속도, 스크린 사양 및 유지 관리 상태에 따라 달라집니다.

대부분의 경우 그렇습니다. 원심 건조는 다량의 자유수를 효율적으로 제거하지만, 많은 압출 성형 및 고사양 응용 분야에서는 최종 수분 함량 목표치를 낮추기 위해 여전히 열 건조 단계가 필요합니다.

스크린 하우징은 청소, 점검 및 교체를 위해 열 수 있습니다. 안정적인 배수와 예측 가능한 배출수량을 위해서는 스크린 상태가 양호해야 합니다.

사용하시는 재료의 종류, 목표 처리량, 일반적인 플레이크 크기, 투입 수분 함량, 상류 세척 단계, 그리고 기계 뒤에 열 건조기 또는 압출 시스템이 있는지 여부를 알려주시기 바랍니다.

A centrifugal dryer for a 1 ton/hour line typically uses a 45-90 kW motor. This is significantly less energy per kg of water removed compared to thermal drying, because water is expelled mechanically rather than evaporated. Combining centrifugal dewatering with a 열 건조기 minimizes total energy consumption — see our centrifugal vs. air drying energy comparison for the calculations.

Centrifugal dryers are optimized for rigid flakes (PET, HDPE, PP). For plastic film, a 필름 압착기 is recommended instead, as it simultaneously removes water and densifies the film. Some recycling lines use both a squeezer and a centrifugal dryer in sequence for maximum dewatering.

In the plastic recycling industry, “centrifugal dryer,” “spin dryer,” and “centrifugal dewatering machine” all refer to the same type of equipment. The machine uses a high-speed rotating screen drum to mechanically separate water from washed plastic flakes through centrifugal force.

Yes — they are the same machine. Recycling plants and equipment buyers use both terms interchangeably. “Centrifugal dewatering machine” emphasizes the mechanical water-removal function. “Centrifugal dryer” emphasizes the moisture-reduction outcome. Manufacturers also market them as plastic dryers, plastic dewatering machines, or spin dryers depending on the target market. The mechanical principle — high-speed rotor inside a perforated screen housing — is identical.

An industrial centrifugal dryer is used in plastic recycling lines to remove surface water from washed flakes before thermal drying or extrusion. Typical placement is after a friction washer or float-sink tank and before a hot-air dryer or pelletizer. For 1 ton/hour throughput, an industrial centrifugal dryer typically uses a 45–55 kW motor and reduces moisture from 30–40% (after washing) to 2–5% (ready for thermal finishing or direct extrusion of HDPE/PP, which tolerate higher moisture than PET).

에이 vertical centrifugal dewatering machine has a vertical rotor shaft and is more compact, suited for limited floor space and lower-capacity lines (400–800 kg/h). A horizontal centrifugal dewatering machine has a horizontal rotor with paddles that convey material along the screen — better for higher capacities (1,000–3,000+ kg/h) and continuous operation. Horizontal designs typically achieve more uniform dewatering on rigid flakes; vertical designs are easier to clean and service.

An industrial plastic dryer machine for recycling lines typically ranges from $8,000 USD (compact 400 kg/h, 37 kW model) to $35,000+ USD (heavy-duty 2,000 kg/h, 55 kW horizontal centrifugal dewatering machine). Final price depends on motor power, rotor diameter, screen specification, material of construction (carbon steel vs SS304), and optional features such as automatic discharge control or integrated dust hood.
