SJ-D type experimental high shear mixing and dispersing emulsifier

The SJ-D experimental pipeline type high shear mixed dispersing emulsifier is an ideal model designed for users to simulate industrial pipeline production. It has a simple and compact appearance, is convenient and practical, and has a power of 0.75KW-1.1KW variable frequency speed control motor. The speed is stable and reliable, and the speed can be adjusted from 0-3000 revolutions per minute. The frequency converter uses imported original digital display, frequency display, and can adjust the speed arbitrarily. It has overvoltage, overcurrent, and overload protection devices. The chamber uses advanced and reliable built-in mechanical seals, and the fixed rotor is designed and manufactured with a cracked long slot multi-layer dual design. The large flow rate is 300L/h, and the high fineness reaches 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 cyclic shear.

The material sprayed from all directions rebounds after hitting the groove wall, forming phenomena such as circulating logistics, turbulence, and turbulence. The liquid layer rubs, collides, tears, and refines, ultimately completing the process of mixing, dispersing, refining, and homogenization.
