Three Roll Mill Application: Lipstick & Carbon Black

The carbon black three roll mill, with a minimum processing capacity of 0.02L/hour to a maximum of 20L/hour, perfectly solves the user’s transition from laboratory testing to small and medium-scale trial production. The highly innovative design makes the device more compact and can be easily placed on the laboratory desktop. The very friendly human-machine interface is realized by the full-touch industrial control screen. The unique online gap correction and recipe menu functions make it easier to use the equipment so that users no longer face the cold equipment, but control it in an interactive operation mode.

Carbon black is widely used in rubber, plastics, coatings, inks, etc. It can be used as a reinforcing agent, colorant, conductive material, anti-ultraviolet agent, etc. Structural properties affect the application, and its particle size, structure, and surface functional groups have a great impact on the application properties. The particle size of carbon black is an important property. The smaller the particle size, the larger the specific surface area, and the improvement in blackness, tinting strength, conductivity, reinforcement, and UV resistance, but its dispersibility decreases, such as in plastics. , The difficulty of dispersion in coatings and inks increases, and the viscosity increases. Coating and ink liquid systems are prone to poor dispersion problems such as flocculation, thickening, agglomeration, and delamination, which have a lot to do with dispersion equipment. Many carbon black manufacturers use kneaders to disperse color paste, but there are problems such as dead corners and uneven dispersion in stirring, which makes the product less than expected.

While the three roll mill under FLE is running, there is no leakage, uniform discharge, good parallelism of the rollers, and no displacement after use; the carbon black slurry is diluted and tested by scanning electron microscopy (SEM), and it is found that there is no large The micelles showed good dispersibility and met customer requirements.

Advantages of FLE three roll mill

① Three roll mill adopts one cycle, it is possible to completely realize the homogenization and dispersion of the material, reduce the particle size, and break the agglomerated particles. The result is a homogeneous slurry that provides the perfect basis for further processing of the material.

②The three roll mill can adjust the distance between each roller with a touch screen to ensure perfect parallelism of the rollers. The elastically tensioned blade socket ensures constant blade pressure and does not require readjustment during operation.

③Rollers of different materials can be used, the choice of roller and scraper material – from stainless steel to alumina, silicon carbide, and zirconia – to meet various needs.

④The safety device on the three roll mill ensures the maximum safety of the operator, and the machine can be cleaned easily and quickly.

⑤FLE’s first IoT and intelligent three-roll mill solution in the industry solves the problems that customers encounter in the use of data that cannot be quantitatively analyzed, data is lost, equipment is independent of each other, and cannot be managed and controlled through the Internet. It allows customers to analyze the data of the equipment, assign and manage the authority of the employees, and keep the whole process record and backup of the equipment operation process, which is conducive to the research, design, and development of processing parameters. In addition, the intelligent IoT platform can also be connected to equipment platforms such as mixers, three-roll mills, feeders, and homogenizers, and can be connected to online viscometers, mid-infrared, particle size analyzers, and other instruments for online monitoring.
