Product Description
PRESSURIZED TYPE REFINING INTERNAL MIXER
Unlock the potential of your production line with our Pressurized Type Refining Internal Mixer, designed for superior mixing efficiency and consistency. This innovative mixing solution applies precise pressure conditions, dramatically enhancing the integration of materials. Ideal for applications in rubber, plastics, and other industries, this mixer ensures a homogenous product with optimal characteristics. With its user-friendly control system and robust construction, the Pressurized Type Refining Internal Mixer streamlines your manufacturing process while maximizing output and quality.
Features
Automated system with high production efficiency, uniform material mixing, convenient material changing, smooth and precise transmission system, noiseless operation, wear-resistant, and corrosion-resistant.
Applications
Used for the mixing and plasticizing of rubber and plastics. Materials are subjected to pressure from a pressure roller in a closed tank, where they undergo shearing, extrusion, stirring, folding, and other kneading actions by two rotors rotating at different speed ratios to plasticize (mix) into the desired raw material. Suitable for large-scale production.

Advantages and selling points of Xihua Machinery Technology's small-scale laboratory internal mixers:
1. Seamless R&D-to-Production Transition
Specifically engineered as a core "pilot-to-mass-production" bridging equipment, Xihua’s small-scale internal mixers (available in 1L, 3L, and 5L capacities) allow researchers to accurately simulate industrial-level mixing processes.
This ensures that experimental data and formulations can be directly scaled up to mass production lines, significantly shortening the technology transfer cycle and reducing R&D costs.
2. Precision PID Temperature Control System
The equipment features an advanced PID intelligent temperature control unit with dual heating and cooling modes.
It supports a wide temperature range from room temperature up to 250℃ (or 300℃ depending on the model) with an exceptional precision of ±1℃.
This highly accurate thermal management prevents temperature fluctuations, ensuring optimal plasticization and preventing material degradation during critical testing phases.
3. Superior Mixing Uniformity & Durable Core Components
Designed for high-intensity laboratory testing, the mixer utilizes a tangential rotor system with a 1.3:1 speed ratio and variable frequency control.
This generates strong shear and extrusion forces to guarantee uniform dispersion of multi-component materials.
Furthermore, the W-type mixing chamber and rotors are crafted from high-carbon steel, treated with 72-hour deep nitriding, and plated with hard chrome, offering outstanding wear and corrosion resistance.
4. Smart PLC Control & Intuitive Operation
Xihua integrates a Siemens PLC control system paired with a 7-inch touchscreen interface.
This smart setup allows for the visual adjustment of parameters like speed and temperature, with a 40% faster computing speed and online programming support.
The user-friendly design makes it highly accessible for new operators, while built-in data storage capabilities facilitate precise R&D analysis.
5. Eco-Friendly & Easy-Clean Design
Addressing the pain points of laboratory environments, the mixer features a fully enclosed structure that effectively eliminates dust and fume emissions. The mixing chamber is constructed from 304 stainless steel with an easy-clean design, preventing material cross-contamination during frequent color or formula changes.
This makes it ideal for processing sensitive materials like metal powders, ceramics, and specialty elastomers.
6. Comprehensive Safety & Ergonomic Features
Operator safety is paramount in lab settings.
The machine is equipped with a robust safety interlocking system, emergency stop buttons, and overload protection. Additionally, the automatic tilt-discharge mechanism (up to 110°) ensures safe and effortless material unloading, minimizing physical strain and maximizing operational efficiency.
