从China供应商批发进口55l/65a (120) Twin Screw Granulator — FOB条款

The 55L/65A (120) twin screw granulator from Nine Delong Machinery (Kunshan) Co.,Ltd. is a co-rotating intermeshing extrusion unit designed for plastic film reprocessing and compounding applications. The machine employs an 11 kW main drive motor and operates with two parallel screws rotating in the same direction to achieve positive conveying and distributive mixing. The 55L designation refers to the screw length-to-diameter ratio, while 65A denotes the screw为了保护用户隐私，此处内容已隐藏。 screw diameter in millimetres, with 120 indicating the centreline distance in millimetres between the two screw shafts. This configuration is suited for processing LDPE, HDPE and PP film waste at throughputs that scale with material bulk density and feed rate.

Twin screw granulators of this configuration typically achieve screw speeds of 300-600 rpm, with specific mechanical energy (SME) inputs of 0.15-0.35 kWh/kg depending on polymer viscosity and filler loading. The intermeshing screw profile creates self-wiping action, reducing residence time distribution and thermal degradation of sensitive materials. Standard material specification for screws is 38CrMoAlA nitrided steel to HRC 58-62 surface hardness, or bimetallic construction with tungsten carbide overlay for abrasive filled compounds. The barrel sections are typically lined with bimetallic liners, and heating is achieved through cast aluminium heater bands with ceramic fibre insulation.

Typical buyers include post-industrial film recyclers, masterbatch compounders, and integrated plastics processors seeking to close-loop their production scrap. The machine produces cylindrical or die-face-cut pellets with diameters of 2-4 mm and lengths of 2-5 mm. Trade terms for Chinese machinery of this class typically operate under FOB Shanghai or CIF destination port, with payment by 30% deposit and 70% letter of credit or telegraphic transfer against shipping documents. Buyers should confirm whether the quoted configuration includes a melt pump, strand pelletiser, or underwater pelletising head, as these downstream options significantly affect delivered capability.

Nine Delong Machinery (Kunshan) Co.,Ltd. is located at No.28 Xiangbengjing Road, Huaqiao Town, Kunshan, Jiangsu Province, 215332, China. Kunshan is a county-level city within the Suzhou metropolitan area, positioned approximately 50 kilometres west of Shanghai, with established logistics corridors to Shanghai Port and Pudong International Airport. The company holds a harbor trust tier designation, which indicates a baseline level of platform verification. The response rate is recorded at 0.00% with zero average response hours, meaning prospective buyers should anticipate delayed or unguaranteed communication and should plan sourcing timelines accordingly.

The supplier's listing describes the 55L/65A (120) twin screw granulator with an focus on automation level and floor space efficiency, though no specific details are provided on screw element geometry, gearbox manufacturer, torque rating, or after-sales service infrastructure. The company overview does not state year of establishment, number of employees, annual revenue, export markets served, or in-house engineering capability. Buyers should request direct factory audit documentation, reference installations, and video verification of operating equipment before committing to purchase. No ISO 9001, CE marking, or other certification claims are asserted in the source data, so compliance documentation must be negotiated explicitly.
