The laboratory mixer is a miniaturized rubber and plastic processing equipment designed specifically for laboratory environments. It is mainly used for mixing, plasticizing, rolling, and formula testing of materials in scientific research institutions, university laboratories, and enterprise research and development centers. This type of equipment can simulate the function of the open mill in industrial production, but it is smaller in scale and more flexible in operation, making it easier to prepare small batches of samples and develop new formulas. The following are some of the main characteristics and uses of a laboratory mixer:

Main features:

1. * * miniaturization design * *: The size of the laboratory mixer is small, suitable for limited laboratory space. Common roller diameters include 4 inches, 6 inches (about 100mm, 150mm), or even smaller, making it easy to operate and maintain.

2. * * High flexibility * *: Parameters such as roller spacing and speed can be adjusted according to different experimental needs. Some models offer manual adjustment, while others are equipped with more advanced electronic control systems.

3. * * Security * *: Usually equipped with safety protection devices, such as emergency stop buttons, to prevent accidental injuries during operation.

4. * * Variable Control * *: Although not as complex as industrial open mills, laboratory open mills may still provide certain speed and temperature control functions to meet the mixing requirements of different materials.

5. * * Intuitive operation interface * *: If customers have requirements, high-end models can use PLC control or touch screen interface, making the operation more intuitive and convenient.

6. * * Easy to clean and maintain * *: Considering the usage environment of the laboratory, the design will facilitate quick cleaning and replacement of components to meet the needs of different experiments.

Usage:

-* * Material mixing * *: Mix rubber, plastic, and other additives to prepare a uniform mixture.

-* * Plastic Refining * *: By the squeezing and shearing action of the roller, the plasticity of the rubber is improved, making it easier to process.

-Formula testing: Prepare samples in small batches to test the performance of new material formulas.

-Teaching and Research: In the teaching and basic research of materials science, it is used to demonstrate the process of material processing and conduct scientific research.

Technical parameter examples:

-* * Roller specifications * *: ranging from 160 x 320mm to 250 x 620mm.

-* * Maximum feeding amount * *: Each feeding amount ranges from a few kilograms to over ten kilograms.

-Front roller speed: The speed range may range from 10 to 16.96 meters per minute.

-Heating and Cooling: Electric heating or water cooling systems can be configured as needed.

The laboratory mixer is an indispensable tool in the field of materials science, which helps researchers and engineers efficiently carry out material pretreatment and new product development under laboratory conditions.

Normally it's CHNT brand. If customers want other band, just tell us.  And if customers want to change speed, there are frequency speed control machine for choice, the machine has inverter in control box. 

Rollers， our rubber open mixing mill machine adopts chilled hard cast iron raw material:

Rubber mixer is one of the important equipment used in the rubber processing industry for mixing, plasticization, dispersion and other processes. It mainly consists of two relatively rotating drums, which achieve the purpose 

of mixing by squeezing and shearing the rubber material through these two drums.

So the roller is a very important component of the rubber mixer:

1. * * Cold hard cast iron * *: This is a material description that refers to cast iron materials that have undergone special treatment. Cold hard cast iron (also known as cold hard iron or wear-resistant cast iron) has high hardness 

and good wear resistance, making it an ideal material for manufacturing open mill drums. Because during the refining process, the drum needs to withstand continuous wear and compression of rubber materials, the use of 

cold hard cast iron can effectively extend the service life of the drum and reduce maintenance costs.

2. Mirror roller: This is a description of the surface condition of the roller. Mirror surface means that the surface of the drum has been finely processed and polished, achieving a very smooth surface effect similar to a mirror. 

This approach has the following benefits:

-* * Reduce adhesion * *: The mirror smooth surface of the drum can effectively reduce the adhesion of rubber materials during the mixing process, which helps to improve production efficiency and product quality.

-* * Uniform mixing * *: A smoother surface can make the rubber material more evenly distributed between the rollers, which is conducive to material dispersion and mixing during the mixing process, and improves the mixing 

effect.

-Easy to clean: The mirror roller is easier to clean after use, maintaining the hygiene conditions of the equipment, which is particularly important for the production of certain rubber products that have strict requirements for 

cleanliness.

In summary, a rubber open mill equipped with a cold hard cast iron mirror roller combines the high wear resistance of the material and the high smoothness of the surface, aiming to improve production efficiency, ensure mixing 

quality, and extend the service life of the equipment. It is one of the high-end configurations in the rubber processing industry.
