650L High Speed Double Planetary Power Mixing Machine

1、Equipment Overview

A、Summary：

Planetary power mixer is an all-round new model which combines the principle and composition of traditional double planetary mixer and high-speed disperser. At present, it is widely used in many fields.

Aiming at the characteristics of high solid content and high viscosity of power battery slurry, our company has developed an enhanced power mixer with higher speed and greater torque based on the original star power mixer. In the design process, the factors such as the speed of the agitator, mixing power, dispersion linear speed, suspension grade, liquid flow pattern and the distribution of turbulence intensity in the barrel are fully considered. The highest linear speed of its high-speed dispersion can reach 23m/s, and the enhanced fried dough twist frame can handle any high viscosity battery slurry. A new mixing method - the fried dough twist box rotates clockwise and its rotation is counterclockwise to ensure that there is no dead angle and no "Climbing" phenomenon in mixing. In terms of sealing, two sets of mechanical seals plus soft and static seals ensure vacuum - theoretically, the sealing performance is enhanced by 30%. PT 100 temperature sensor directly contacts the material, so the measurement is more accurate and the reaction speed is faster, and the error is only between ± 0.5 ℃. This machine is composed of base, beam, column, sealing cover, feeding cylinder, transmission and electric control system.
