6 Inch Double-Frequency Two-Roll Open Mixing Mill with Bearing SPKL-030

Description

In the rubber and plastic compounding manufacturing, open mixing mills play a crucial role in material blending, plasticizing, and refining. Precision, consistency, and control are the keys to producing high-quality materials.
The 6 Inch Double-Frequency Two-Roll Open Mixing Mill with Bearing , also called Dual Inverter Two-Roll Mill , it is a high-precision mixing solution designed for laboratory and small-scale rubber or plastic compounding.
Traditionally, open mixing mill adopt one single-motor before, but as technology evolves, so do the demands for efficiency, flexibility, and automation.
Nowadays , the laboratory two rolls rubber mixing mill are equipped with dual inverter (VFD) motors, this two roll mill allows independent speed control of each roll, which provide precise adjustment of friction ratio for optimal material blending.

Advanced Double-Frequency Drive System

This two roll open mixing mill equipment adopts a double-frequency inverter control system, which allow independent frequency control and separate speed control of the front and rear rolls. Compared with traditional single-frequency mixing mills, this double frequency open mixing mill design offer multiple advantage as follows:

1. Precise control of roll speed and friction ratio independently
2. Flexible adjustment for different rubber formulations
3. Smooth start-up and stop, reducing mechanical shock
4. Improved dispersion efficiency and mixing uniformity
5. Bearing-Type Roll feature Low Noise & Long Life

Different from conventional bush-type open mixing mills machine, this double frequency open mixing mill with bearing features a bearing-supported roll structure, which offer several performance advantages as follows:

* Lower friction and reduced heat generation
* Significantly lower operating noise
* Higher rotational accuracy and stability
* Reduced maintenance frequency

High-quality heavy-duty bearings are sealed and lubricated, ensuring long-term reliable operation even under continuous production conditions.
