High speed disperser is primarily used to shear, disperse, and emulsify solid particles in liquids or slurries at high speeds. The high-speed rotating dispersing disc subjects the material to strong shear and impact forces, resulting in rapid dispersion and uniform mixing. It is widely used in industries such as coatings, inks, adhesives, resins, and cosmetics.
Q
What is the difference between high speed disperser and conventional mixer?
• Conventional mixer: Primarily used for uniform mixing with gentle force, it is suitable for low-viscosity materials or those that do not require strong dispersion. • High speed disperser: Operating at high speeds, high speed disperser generates strong shear forces and is suitable for applications requiring particle breakup, wetting, and fine particle size reduction.
Q
What materials are suitable for dispersing with a high-speed disperser?
What is the typical speed of high speed disperser?
The typical speed range for high speed disperser is 0–3000 rpm. The speed can be adjusted based on customer requirements, such as material properties, particle size, and dispersion.
Q
How to choose the right high speed disperser?
• Processing capacity (L): Determine the equipment volume. • Material viscosity: Select the appropriate motor power. • Dispersion requirements: Whether to use standard dispersion or nano-dispersion. • Production scenario: Laboratory R&D or large-scale industrial production.
Q
How should high speed disperser be cleaned and maintained?
• Cleaning: After shutting down the high speed disperser, rinse the dispersing disc and cylinder with solvent or water. • Maintenance: Regularly inspect the motor, bearings, and seals and maintain lubrication. • Avoid idling or prolonged overload operation to extend the life of the high speed disperser.
Q
Can high speed disperser replace sand mill?
It can't completely replace a sand mill. • High speed disperser: Primarily performs initial dispersion and mixing. • Sand mill: Used to refine particles to achieve a higher fineness. The two are often used in conjunction: first dispersion, then grinding.
Q
What are common high speed disperser faults and their solutions?
Large vibration → Check for rotor eccentricity or loose mountings. High noise → Check bearings for damage. Poor dispersion performance → Check for sufficient speed and proper material ratio. Motor overheating → Check for overload or insufficient cooling.
