SJ-800 series double-layer high shear mixing emulsifier

The SJ-800 series double-layer high shear mixing emulsifier has two fixed rotor devices with opposite working directions. The upper working chamber is surrounded by a cylindrical cover plate and fixed to the fixed column, forming a closed space as a moving stator head for the upper rotor to cooperate.

2. The high-speed rotation of the upper rotor forms a strong downward centrifugal suction force, which sucks the liquid level particles into the upper working chamber and undergoes mechanical and hydraulic shearing dozens of times per minute inside the chamber.

3. The rotor at the lower end rotates at high speed, and the material at the bottom is sucked into the long hole stator head at the lower end. Strong centrifugal compression causes the material to spray along the long hole groove in all directions, forming strong mechanical shear, liquid layer friction, tearing, refinement, and homogenization.

The dispersed impeller located between the upper and lower fixed rotors enhances the vortex and turbulence.

The reasonable design concept, precise manufacturing process, ideal mixing, dispersion, refinement, and homogenization effects of the 5 SJ-800 series double-layer high shear mixing emulsifier greatly reduce production equipment costs. This machine is suitable for adhesive, rubber dissolving lotion, silicone dispersant, various coatings, paints, inks, resins, asphalt, lubricants and other industries.

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.
