Talking About High Speed Shearing Machine

  The high-speed shear emulsifying machine has the main effect in the mixing system of industrial equipment, especially in the fields of solid-liquid inclusion, liquid-liquid inclusion, oil-water emulsification, loose homogenization and shear grinding. The reason why it is called emulsifying machine is that it can complete the effect of emulsification. Lotion is formed by the inclusion of oil-water two-phase media, which can be divided into two systems: water in oil or oil in water. To complete emulsification, there are two requirements: one is the intense mechanical cutting and loosening effect. The fluid media of water phase and oil phase are also cut and broken into small particles, and then when they are merged, they will be soaked and mixed with each other to form lotion. Second, suitable emulsifier acts as a bridge between oil and water molecules. Through the effect of its charge and intermolecular force, oil and water mixed with lotion can be stored in accordance with our expectations.

  At present, the use of shear emulsifying machine is not limited to "emulsification", because its common shear effect is to crush, destroy and impact the powder particles in the liquid, and finally refine them to particle size, and then fully mix the solid matter into the liquid to form a relatively constant suspension. Of course, like emulsifiers, the immutability of suspensions can be enhanced after adding dispersants. When a solid substance can be melted by the liquid after a certain time of contact with the liquid, the small particles formed by shear impact will be melted by the liquid more quickly, because they are many times larger than the external product.

  We can also call the shear emulsifying machine a homogenizer. For the convenience of differentiation, it can be called high-speed or high shear homogenizer, so that there are many names for the shear machine: Vacuum shear machine, high shear emulsifying machine, high shear homogenizing emulsifying machine, high-speed shear machine, vacuum homogenizing emulsifying machine, pipeline homogenizing emulsifying machine, etc.

  The high shear disperser is a process of rapidly and uniformly transferring one or more phases (liquid, solid and gas) into another immiscible continuous phase (usually liquid). And in general, the phases are immiscible with each other. When external energy is input, the two materials recombine into a homogeneous phase. Due to the high tangential speed generated by the high-speed rotation of the rotor and the strong kinetic energy brought by the high-frequency mechanical effect, the materials are subjected to strong mechanical and hydraulic shear, centrifugal extrusion, liquid layer friction, impact tearing and turbulence in the narrow gap between the stator and the rotor, forming suspension (solid / liquid), lotion (liquid / liquid) and foam (gas / liquid). So that the immiscible solid phase, liquid phase and gas phase can be uniformly and finely dispersed in an instant under the joint action of the corresponding mature technology and appropriate additives, and stable high-quality products can be obtained through high-frequency cycling. The high shear disperser is composed of 1-3 working chambers. Under the high-speed drive of the motor, Wuke moves at a high speed in the narrow gap between the rotor and the stator, forming turbulent flow. The materials are subjected to the comprehensive effects of stronger hydraulic shear, centrifugal extrusion, high-speed cutting, impact and grinding, so as to achieve the effect of dispersion, dispersion and crushing. The physical properties of the processed materials, the number of working chambers, and the time the materials stay in the working chambers determine the particle size distribution range, the effect of homogenization and refinement, and the output.
