High speed dispersing machine working principle
1 The strong centrifugal force pushes the material from the radial direction into the narrow and precise gap between the rotors. At the same time, it is subjected to centrifugal force, liquid layer friction and hydraulic impact, and the materials are initially dispersed.
2 The rotor rotating at high speed of the disperser produces a linear velocity of at least 15 m / s. The material is fully dispersed and broken under the action of strong hydraulic shearing, liquid layer friction, tearing collision, etc., and is simultaneously ejected through the stator slot at a high speed.
3 The material of the disperser is continuously injected from the radial high speed, and the flow direction is changed under the resistance of the material itself and the wall of the container. At the same time, under the action of the upper and lower axial suction forces generated in the rotor area, the upper and lower two are formed again. The stock has a strong turbulence. The material is recycled several times to complete the dispersion process.

High Speed Disperser (Hydraulic Lifting) has dispersing and mixing function, which used for mass production; Equipment with inverter has stepless speed, can operate for a long time. It has stable running and low noise; Mixing disc is easy to be replaced, and can change different forms of dispersing discs according to production technology.Lifting structure adopts hydraulic cylinder as actuator, stable lifting, integrated hydraulic station, environmental and without leakage. It is an ideal grinding machine for materials with many varieties and many colors.
Material Viscosity: <=50,000 cps
Production Capacity: 50-10,000L
Application Fields: Suitable for dispersing, mixing materials in industries such as biology, pharmacy, food, paint, ink, adhesives, pigment, fertilizer etc.
Through the high-speed rotation dispersing disc, the material will become in annular form flow, resulting in strong vortex flow, which descend down to the bottom of the vortex in spiral state. During the High Speed Disperser process, materials are dispersed, dissolved, mixed and emulsified efficiently due to the strong shearing crash and friction among the particles.
A steel fabricated enclosure inside which is installed the drive assembly consisting of a set of balanced pulleys, V belts, electric motor and motor tensioning device. The drive head is of hinged type construction which can be opened for maintenance.
