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
