InNovaZ LM Nano Ultrasonic High-Speed Disperser

The LM 240 is a high-end intelligent equipment designed for homogenizing and dispersing nano-slurries. Due to the **linear speed of 60 m/s** of the dispersion wheel and the action of the baffle plate, a specific flow trajectory of the slurry is formed within the dispersion tank. Under the centrifugal force of the dispersion wheel, the slurry rapidly detaches from the outer wall of the dispersion wheel and impacts the tank wall at high speed. As the slurry quickly leaves the wheel wall, a vacuum is instantly created on the surface of the wheel wall. Consequently, the slurry inside the dispersion wheel passes through the dispersion holes under the influence of this vacuum. The residence time of the slurry in the dispersion tank is only about 30 seconds. The **cooling system** ensures that the slurry is adequately cooled during high-speed dispersion, fully meeting the specific process requirements of users.

▎Practice is the **criterion** for testing truth.▎

Pühler and LEIMIX GmbH from Germany have jointly launched an industry-proven nano ultrasonic high-speed disperser in China, which can be used for the continuous production of power battery slurries. To meet the demands of our valued customers, Pühler has established a customer experience center in Guangzhou, offering you the **best solutions and testing conditions** in terms of both equipment and processes.

▎Quality and Efficiency – You Can Have Both▎

① Non-destructive dispersion improves the dispersion quality of the slurry without damaging the original morphology of the material.

② Stable feeding speed and a special dispersion method ensure the consistency of slurry dispersion.

③ Improved the stability of slurry viscosity, which is more conducive to coating and enhancing the quality of electrode sheets.

④ Excellent dispersion effect maximizes the performance of conductive materials, thereby reducing the internal resistance of lithium-ion batteries.

▎Mixing and dispersion mechanisms▎

Shear impacts the inner wall of the container, forming a thin-film turbulent dispersion layer between the stationary container wall and the high-speed rotating disperser. Within this thin-film turbulent dispersion layer, the power battery slurry undergoes intense collisions and friction under high shear forces, rapidly breaking up agglomerates. The high-speed dispersed power battery slurry flows out of the dispersion device and enters the ultrasonic device, where the resonant destructive impact force (microbubbles) generated by irradiation further disperses the slurry at the nanoscale. This ensures consistency in fluid dispersion quality and improves production efficiency.

▎The combination of high-energy thin-film turbulent dispersion and ultrasonic cavitation dispersion ensures that no "agglomerates" slip through the cracks.▎

① High-energy thin-film turbulent dispersion: Within the thin-film turbulent dispersion layer, the immense shear stress generated by the high-speed rotation of the dispersion disc causes the slurry to undergo intense collision and friction between the container's inner wall and the dispersion disc, thereby rapidly breaking up agglomerates.

② Ultrasonic cavitation dispersion: Utilizing the crushing effect of shock waves and micro-jets generated by ultrasonic cavitation to achieve the dispersion of particles, it is especially suitable for dispersing agglomerated nanoscale particles.
