The SJ-A experimental high shear mixing and dispersing emulsifier is an economical and practical model, with a compact appearance, made of SUS304 stainless steel, weighing 15Kg, and a hand-operated lifting device that can be easily lifted to the required height. The lifting stroke is 300mm, the 550W series excitation single-phase motor, the electronic frequency conversion speed control system, the speed can be adjusted from 0-10000 revolutions per minute, the speed is digital, and the stator head has three types of circular holes, long holes, and mesh holes, which can be easily interchanged according to the viscosity and required fineness of the material. Its working capacity is 1-10 liters, and the high fineness can reach 0.5-2 μ m.

Introduction to the working principle of SJ series high shear mixing emulsifier

　　The SJ series high shear mixing and dispersing emulsifier is widely used by users due to its six significant features of high-speed mixing, dispersion, rapid refinement, dissolution, homogenization, and emulsification. Mechanical and hydraulic high-speed shear force is the key to the success of the SJ series. The high-speed rotating rotor and stator are precisely matched, generating high shear line velocity and high-frequency mechanical effects, which bring about mechanical and hydraulic shear forces, ensuring that materials can withstand hundreds of thousands of shear cuts per minute. When the material is exhausted, the precision gap between the rotor and stator is subjected to strong centrifugal compression, shear, spray, liquid layer friction, collision, tearing refinement, and complex liquid flows such as turbulence, turbulence, and eddy currents. Under the joint action of corresponding mature process conditions, immiscible liquid phase, liquid gas phase, and liquid solid phase are instantly uniformly and finely mixed, dispersed, refined, and emulsified. This cycle repeats to obtain high-quality products.

The high-speed rotor and tightly matched stator generate centrifugal force, which sucks materials into the stator chamber from the lower or upper lower parts.

—The rotor brings the material into the stator gap, and the material is subjected to centrifugal compression. When it passes through the stator head (long length L, mesh or circular hole), it produces a violent spray and withstands strong mechanical or hydraulic shear. At the same time, new material is continuously brought into the stator cavity at the center of the rotor, forming a cyclic shear.

—The material sprayed everywhere bounces back after hitting the groove wall, forming phenomena such as circulating logistics, turbulence, and turbulence. The liquid layer experiences friction, impact, tearing, and refinement, ultimately completing the process of mixing, dispersing, refining, and homogenization.
