Efficient And Energy-saving Triple Screw Extruder

This model is a new generation triple screw extruder developed by Nanjing Kelongwell Chemical Machinery Co., Ltd. for the high-precision mixing market. The equipment integrates efficient and energy-saving transmission technology with a three screw collaborative mixing mechanism, which is particularly suitable for the high-end plastic granulation field, such as high dispersion masterbatch, high filling modification, and plastic extrusion processing of special engineering plastics. While ensuring excellent mixing quality, it significantly reduces energy consumption per ton of material, providing customers with more competitive comprehensive operational solutions.

·Three axis energy distribution technology: evenly distribute input power to three screws, resulting in higher torque density per machine and stable operation in high viscosity systems, enhancing the process adaptability of plastic extruders.
·High energy mixing zone design: By combining special kneading blocks with toothed discs, multiple shear and diversion structures are formed, allowing the triple screw extruder to achieve ideal dispersion effects under short to diameter ratio conditions.
·Energy saving drive system: adopting efficient permanent magnet synchronous motor and high transmission efficiency gearbox, reducing energy consumption by more than 15% compared to traditional models, especially suitable for continuous plastic granulation production lines.
·Intelligent temperature control module: segmented barrel heating/cooling system, combined with independent PID control, ensures stable melt temperature during plastic extrusion process and reduces material thermal degradation risk.

Noted: Details depend on your requirements and need.

The core value of a triple screw extruder lies in achieving better mixing with less energy consumption. Compared with the twin screw model, this equipment increases the melt exchange frequency exponentially and significantly improves the dispersion and mixing efficiency at the same screw length to diameter ratio. In actual plastic granulation production, customers can reduce one mixing process, directly lowering labor and turnover costs. In addition, the forced conveying effect formed by the three screw structure makes the plastic extruder more adaptable to powder feeding, and can maintain stable pressure building capacity even under high filling ratios, ensuring uniform granulation and dense particles.

·Functional masterbatch: Efficient production of antibacterial masterbatch, flame-retardant masterbatch, and color masterbatch, especially suitable for organic pigment systems with high dispersion difficulty.
·High filling modification: PP/PE is filled with over 70% calcium carbonate or talc powder, significantly reducing raw material costs.
·Cable material: Plastic extrusion granulation of low smoke halogen-free flame-retardant cable material and silane cross-linked cable material, requiring uniform distribution of fillers and precise temperature control.
·Modification of recycled plastics: reinforcement, toughening, and odor removal treatment of recycled plastics to enhance the added value of recycled materials.
·Special alloys: Alloy systems with poor compatibility, such as PC/PBT and PP/PA, are finely controlled in terms of microstructure through a triple screw extruder.

Nanjing Kelongwell Chemical Machinery Co., Ltd. provides full process customization services from screw combination optimization to whole line integration.
·Customized screw configuration: Design specialized screw components for the conveying, melting, dispersing, and exhaust sections based on the type and viscosity characteristics of the fillers in the formula.
·Processing section selection: High wear-resistant bimetallic barrel and specially coated screw can be selected to meet the requirements of fiberglass reinforcement or highly corrosive materials.
·Automated control: Integrate MES interface to achieve real-time monitoring of process parameters and traceability of production data.
·Granulation form: According to the characteristics of the material and downstream processes, flexible selection of strip granulation, underwater granulation, or air-cooled die surface hot cutting systems can be made.

Q1: How sensitive is the triple screw extruder to material moisture?
A: The screw configuration of the triple screw extruder can be configured with multiple exhaust zones according to the material characteristics. For engineering plastics with strong moisture absorption properties (such as PET and PA), we can set up multi-stage vacuum exhaust ports on the barrel, combined with efficient screw components to ensure that moisture and small molecule volatiles are fully removed during the plastic granulation process, and the finished particles have no pores.

Q2: Can a triple screw extruder improve dispersion compared to a twin screw extruder in the production of color masterbatch?
A: It can significantly improve. Masterbatches require extremely high dispersion of pigments, and traditional twin screw extruders sometimes require two or even three rounds of mixing to achieve satisfactory results. The triple screw extruder, with its three-axis interactive mixing zone, can achieve rapid crushing and uniform spreading of pigment aggregates, usually achieving the dispersion level required for high-end color masterbatch in one pass, greatly reducing energy consumption and labor costs.

Q3: Is it difficult to operate and maintain the equipment?
A: Nanjing Kelongwell Chemical Machinery Co., Ltd. fully considered the convenience of operation in the design. This plastic extruder adopts a split type barrel and quick detachable screw connection structure, and the screw components can be quickly extracted for cleaning or replacement. The control system is equipped with a touch screen and fault self diagnosis function, and operators can master parameter settings and daily maintenance points after short-term training.

Q4: Can the triple screw extruder be used for processing heat sensitive materials?
A: Absolutely possible. Due to the three screw structure allowing for shorter screw lengths and lower rotational speeds at the same output, the residence time distribution of materials in the barrel is more concentrated. At the same time, we have equipped a precise temperature control system and optimized shear combination, which can effectively prevent local overheating and decomposition of heat sensitive materials such as PVC and TPU during plastic extrusion.

Q5: Can your company provide turnkey service for the entire plastic granulation production line?
A: Yes, it is. Nanjing Kelongwell Chemical Machinery Co., Ltd. not only provides the main unit of the triple screw extruder, but also designs the upstream batching system (weight loss scale, high-speed mixer), downstream plastic granulation system (cooling, cutting, screening, packaging), and central control system. We provide full process services from process design, equipment manufacturing to on-site installation and commissioning to ensure customers can quickly start production.
