1.Description

In many processes of paint or ink production, it is often necessary to uniformly distribute solid materials in a liquid medium. This process is called dispersion. During dispersion, the attractive forces between extremely small particles must be broken. The sawtooth-shaped circular dispersion disc of a high-speed disperser, driven by an electric motor, achieves solid-liquid dispersion, wetting, deagglomeration, and stabilization within a container. Its working principle can be roughly described as follows:
→ The slurry forms a rolling ring-shaped flow, creating a strong vortex, with particles on the slurry surface spiraling downward to the vortex bottom;
→ A turbulent zone forms 2.5-5 mm from the edge of the dispersing disc, subjecting the slurry and particles to intense shear and impact;
→ Two counter-current streams form outside the zone, ensuring thorough circulation and agitation of the slurry;
→ Below the dispersing disc, the slurry flows in a laminar state, with layers of slurry at different velocities mutually diffusing to achieve dispersion.
The high-speed disperser is suitable for high-speed mixing, dissolving, and dispersing of liquid and liquid-solid phase materials in industries such as coatings, dyes, inks, pigments, papermaking, cosmetics, food, resins, adhesives, emulsions, pharmaceuticals, petroleum, pesticides, and daily chemicals. The speed can be freely adjusted.
Features:
*Equipped with high-quality squirrel-cage motors and variable frequency speed controllers for speed regulation.
*The variable frequency drive is directly mounted on the machine, with its display screen showing the shaft speed in real time.
*Brushless design prevents spark generation during operation.
*Low noise, high speed, high torque, long service life, and wide speed regulation range.
*The lifting rods of the BGD 740/1 and BGD 740/2 are marked with scales, making it convenient for users to adjust the lifting height (distance between the dispersing disc and the bottom of the mixing tank).
*All major components are made of stainless steel for corrosion resistance.
*Two different sizes of dispersing discs are included as standard, and various sizes of grinding discs and stainless steel double-walled hoppers can be optionally selected to perform grinding functions.
*Power supply: 220V 50Hz
