I: 20L Internal Mixer | 20-Liter Internal Mixer | Internal Mixer; Machine Purpose

The 20L Internal Mixer | 20-Liter Internal Mixer | Internal Mixer Manufacturer is one of the models in the medium-scale production internal mixer category, primarily used for batch production. It features an excellent mixing system, precise temperature control, and professional anti-powder leakage. Core components are imported, resulting in low maintenance rates, making it an ideal rubber and plastic mixing equipment.


II: 20L Internal Mixer | 20-Liter Internal Mixer | Internal Mixer Manufacturer; Application Scope

The 20L Internal Mixer | 20-Liter Internal Mixer | Internal Mixer Manufacturer is widely used for raw materials in rubber and plastic products such as EVA, PVC, TPR, PE, PP, PC metal powder, ceramic powder, functional masterbatch, rubber additives, shoe materials, rubber tires, sealing parts, electronic products, wires and cables, automotive products, etc.

III: 20L Internal Mixer | 20-Liter Internal Mixer | Internal Mixer Manufacturer; Working Principle


At specific temperatures (depending on the material—some require heating, others cooling), raw materials are added. Through the rotation of the rotor, under conditions reaching the plasticizing temperature, the raw materials are mixed to achieve the purpose of mixing, ensuring full blending of various additives and base rubber for uniform distribution of all components.


IV: 20L Internal Mixer | 20-Liter Internal Mixer | Internal Mixer Manufacturer; Technical Features


The 20L Internal Mixer | 20-Liter Internal Mixer | Internal Mixer Manufacturer is suitable for small to medium batch production and sampling tests. This model features a compact structure, short mixing time, high efficiency, excellent dispersion, long anti-powder leakage duration, wear resistance, and extremely low maintenance frequency. All technology is sourced from Taiwan, with core parts imported.

V: 20L Internal Mixer | 20-Liter Internal Mixer | Internal Mixer Manufacturer; Product Features

1. Large mixing capacity, short time, high production efficiency; 2-3 times that of open mills;


2. Effectively reduces dust flying;


3. Minimizes loss of compounding agents;


4. Improves product quality and working environment;


5. Safe and convenient operation, reducing labor intensity;


6. Facilitates mechanization and automation operations;


7. Intermittently plasticizes and mixes polymer materials in a sealed state with adjustable temperature and pressure;


8. The chrome plating layer of the mixing chamber is 0.12~0.18mm, higher than similar manufacturers, significantly extending the service life of the mixing chamber;


9. Electrical components use imported brand products, ensuring stable and precise operation;


10. Rotor blade manufacturing process: imported alloy steel overlay welding - high-precision polishing - carburizing - surface hard chrome plating to ensure wear resistance and durability. Specifically designed for mixing highly filled masterbatches, iron powder, or magnetic powder materials with extreme wear resistance;


11. Material: Rotor shaft core is made of 38CrMoALA, nitrided to HV950-1050, with a depth of 0.6-0.75MM, brittleness not exceeding grade 11, ensuring high hardness, high load capacity, strong torque, no shaft breakage, and smooth transmission;


12. The reducer uses hard-toothed surfaces, providing high transmission torque, and is made of industrial-grade 42CrMo high-hardness material with nitriding treatment;


13. The main machine uses reverse discharge for unloading, ensuring clean discharge and easy cleaning;


14. The rotor shaft end sealing ring uses the company's proprietary technology, offering excellent sealing performance.
