cP Viscosity
A high-speed disperser is essential industrial mixing equipment that helps in uniformly mixing and dispersing solid particulates within a liquid by applying high shear and turbulent flow via a rotating disperser blade. The high peripheral speed of the blade creates strong pumping action that breaks down agglomerates, and thoroughly wet powders and pigments, creating homogenous mixtures with a consistent particle size distribution.
We have customized high-speed dispersers for demanding applications in the paints, inks, coatings, adhesives, cosmetics, chemicals and allied manufacturing industries. We offer complete systems for your dispersion and mixing needs including compact bench-top high-speed mixers for laboratory R&D and large-scale production mixers with hydraulic lifting systems and integrated control boxes.
High Shear Mixing:
Effective deagglomeration and particle size reduction with the application of mechanical shearing.Vortex Formation:
A controlled vortex draws powders into the shear zone for rapid moistening.Turbulent Flow:
We have incorporated systems that ensure uniform dispersion throughout the entire batch.Precise Control:
Optimized blade speed and tip speed with the use of variable speed drives.How It Works: High Speed Disperser Working Principle
The high speed disperser working principle is based on converting rotational movement into shear energy within the liquid. This is done by using the high speed impeller with a specific blade diameter and profile. When the impeller rotates, the tip speed is the most important factor, and is measured in feet per minute. This factor determines the shear level and the turbulent flow level.
Vortex Formation
The circulation pattern generated by the rotating saw-tooth disc draws materials from the top and pushes them down to the blade zone. This circulation ensures that every material gets to pass through the high shear region.
High Shear Zone
With the high peripheral speed at the blade tips, shear forces are generated that break down agglomerates. This is also where individual particles are separated and the surfaces of the powders are quickly wetted.
Turbulent Mixing
The disc that has been designed to create a turbulent flow develops a chaotic movement among the fluids that displace the particles and create a homogeneous dispersion. This ensures that the quality of the end products are consistent.
The Dispersion Process Step By Step
The impeller creates three effects when liquid is forced through gaps between serrated blade teeth.
01
Using Mechanical Impact: The rotating blade teeth can strike particles and de-agglomerate them by breaking apart and exposing new surfaces.
02
Using Hydraulic Shear: The liquid’s velocity can create a shear force that continues to reduce the size of the particles.
03
Using Cavitation (in some cases at very high speeds): Micro-bubbles can form and collapse, which creates high pressures that can help with the process of de-agglomeration.
When creating pigment dispersions or emulsions, this type of high shear is very important due to the controlled particle size distribution and the prevention of re-agglomeration. All variables of the disperser design, high-speed disc geometry, and the control box settings will determine the repeatability of the production and the quality of the product.
Important Parts of a High Speed Disperser
Knowing the important components will help you choose the right equipment and support the best possible performance.

Key Things to Consider When Selecting a High Speed Disperser
When you understand the following parameters, you can select the best disperser and improve the efficiency of your dispersion process and the consistency of your product dispersion.
Blade Diameter
For optimal flow, a blade diameter of about 1/3 the diameter of the tank is ideal. This determines the circulation pattern of the vessel and impacts tip speed.
Typical ranges are 2 to 24 inches
RPM / Blade Speed
The rotational speed of the impeller is determined by a combination of blade diameter and tip speed. Variable frequency drives provide precise control of the blade speed.
Ranges are from 0 to 3000 RPM
Viscosity Range
Dispersers typically handle low to medium viscosity. An anchor agitator helps high viscosity materials over 50,000 cP and is dual-shaft designed.
Ranges are from 0 to 500,000 cP
Motor Power (KW)
The shear level, batch size, and viscosity determine the power requirement. As a rule of thumb, medium viscosity requires about 1 KW per 10 gallons.
Ranges are from 0.5 to 500 KW
Batch Capacity
Working volume capacity can range from laboratory scale to full production. The circulation efficiency and vortex formation is affected by the vessel geometry.
1 – 5,000 Gallon

Common Dispersion Challenges Solved by Our High Speed Platform Disperser Systems
We are a China disperser manufacturer with more than enough experience developing solutions for the challenges you face with reliable and consistent dispersion.
01
Problem
Poor Pigment Wetting & Fish Eyes
When the pigment and powders are not mixed well, it results in the formation of stubborn agglomerates and fish eyes. This causes mixing to be inconsistent and can create coating defects and rejected batches.
Solution
Optimized Shear Force & Vortex Control
High speed disperser creates a controlled vortex with the right tip speed to pull powder into the vortex shear zone. Our staged speed profiles ensure complete wetting without air being trapped.
02
Problem
Inconsistent Batch to Batch Quality
Particle size distribution is set between batches. The uniformity of viscosity and dispersion quality is inconsistent, leading to customer complaints, rework, and wasted raw materials.
Solution
Accurate Controls & Repeatability
The digital electric control box with VFD allows customizable speed profiles which can be saved for repeatable results. Parameters are documented to ensure consistent quality on the blades after each batch.
03
Problem
Air Entrapment & Foaming Issues
Too much of a vortex and air gets sucked into the mix, and trapped bubbles create foam. This can negatively impact the product, especially in coatings, inks, and sensitive emulsions.
Solution
Vacuum Functionality & Appropriate Blade Design
Dispersers with vacuum capabilities remove air from the processing mix. Adjustable hydraulic lifts set and maintain the impeller at optimum depth. Appropriate blade diameter selection reduces air entrapment and increases shear.
04
Problem
High Viscosity Processing Difficulty
Standard mixers have difficulty with thick pastes and materials higher than 50,000 cP. Due to inadequate mixing, there may be unmixed areas, overheating of motors, and insufficient dispersion.
Solution
Dual Shaft Design with Anchor Agitator
Multi-shaft mixers combine a high-shear disperser with a slow-speed anchor and wall scraper. This guarantees complete circulation for adhesives and sealants up to 500,000 cP and ensures uniform mixing.
05
Problem
Safety Concerns with Flammable Solvents
Working with solvent-based coatings, inks, and chemicals with standard motors may pose a fire risk due to overheating, and can be classed as a conduit for hazardous areas.
Solution
Explosion-Proof & Intrinsically Safe Design
Our Explosion-proof high-speed disperser with ATEX/IECEx certification, includes sealed control boxes and an integrated grounding system. We offer a pneumatic lift to remove electrical ignition sources.
06
Problem
Scale-Up Failures from Lab to Production
Formulas made in the laboratory fail to reproduce at scale in production. With increases in batch volume, there is a substantial change in particle size and the quality of dispersion which may require an expensive reformulation.
Solution
Geometric Similarity & Tip Speed Matching
Do not change the tip speed in feet per minute, from during the scale-up, and maintain the same impeller to vessel ratio. Our engineers assist in translating laboratory parameters to ensure consistent outcomes at any production scale.

Lithium Battery Manufacturer Zero-Defect Slurry with Vacuum High Speed Disperser
Project Overview
The Challenge
The client is a fast-growing manufacturer of electric vehicle (EV) batteries for North American EVs, and has been experiencing high defect rates in their electrode slurry prep. As they transitioned from pilot to full-scale production, slurry quality was leading to unacceptable cell rejection rates.
Critical Issues Identified:
- Micro-bubble entrapment: Bubbles formed during high speed mixing were leading to coating defects, with ~3.2% of coated electrodes exhibiting pinholes post drying.
- NMP solvent evaporation: During open vessel processing, NMP (N-Methyl-2-pyrrolidone) solvent evaporation resulted in viscosity drift and a need for ongoing formula adjustments.
- Active material agglomeration: Agglomerates of NCM 811 cathode material that were not fully disintegrated were producing non-uniform lithium-ion transport within the finished cells.
- Safety concerns: NMP vapors in the processing environment were reaching OSHA exposure limits, and costly ventilation improvements were necessary.

Specialty Ink Manufacturer Solves Pigment Agglomeration with Optimized Tip Speed Control
Project Overview
The Challenge
With over 40 years of operation, this ink manufacturer and their family business was facing issues in meeting quality demands of their packaging customers. Their current disperser, although workable, was failing to provide the precision and control needed for today’s stream of high-performance inks.
Key Issues:
- Lack of consistency for the fineness of the grind: Hegman gauge readings ranged across batches from 5 to 7 and required their specification from the customers to hold to a 6+ consistent reading.
- Lack of consistency for color: This affected packaging due to critical branding color match with a Delta E value exceeding 1.5, which also resulted in an issue of color consistency across batches.
- Damage to organic pigments: Over-shearing phthalocyanine blue and green pigments resulted in gloss loss and a color shift in the final print.
- Absence of process documentation: A lack of actual processing parameters made for poor troubleshooting, difficulty in reproducibility, and loss of consistency.
IDA Solution: Precision-Controlled Dispersion
A member of our technical team has closely analyzed the client’s formulations and determined that the main issue was the absence of tip speed control. Various pigment types necessitate differing levels of energy input; gentler processing is required for organic pigments as compared to inorganic pigments such as TiO2.
Here are the features:
- VFD: Adjustable between 0-1500 RPM and can be set to any 1 RPM step.
- RPM Display: Updated in real time and can capture and record the data.
- Blade Options: Standard 12″ Cowles blade for most inks and a 12″ ring blade for shear sensitive formulations.
- Integrated Tip Speed Calculator: The human-machine interface (HMI) will show the projected tip speed based on the settings and the diameter of the blade.
Optimizing Tip Speed
The client and IDA engineers collaborated to define the most productive ranges of tip speed for pigments:
| Type of Pigment | Tip Speed (fpm) | RPM |
|---|---|---|
| TiO₂ White | 5,000-5,500 | 1,275-1,400 |
| Carbon Black | 4,500-5,000 | 1,150-1,275 |
| Phthalocyanine Blue/Green | 3,500-4,000 | 890-1,020 |
| Quinacridone Red/Violet | 3,000-3,500 | 765-890 |
The formula for calculating tip speed is Tip Speed (fpm) = (π * RPM * Blade Diameter (inches)) / 12
Results
Metric Result
| Metric | Before | After | Improvement |
|---|---|---|---|
| Hegman Gauge Consistency | 5-7 (inconsistent) | 6.5-7 consistently | Achieving 6.5-7 consistently |
| Color Variation (Delta E) | 1.5 | 0.4 | 0.4 (Down from 1.5) |
| Batch Rejection Rate | 8% | <1% | <1% (Down from 8%) |
| Process Documentation | None | 100% | 100% of processes are fully documented |
| Customer Complaints | Baseline | Reduced | Down 85% in the first year |
Frequently Asked Questions (FAQs)
One type of industrial mixing machine is a high-speed disperser. This machine temporarily suspends solid particles in a liquid while applying high shear rates. The machine uses a rotor that quickly rotates against a stationary component. The rapid turning of the rotor creates strong hydraulic and mechanical shearing which generates a pumping action. This action draws material through the rotor/stator gap for size reduction and improves the wetting of materials.
High speed industrial dispersers are used in the paint and ink industries to process paint colors. They break down the color pigments and binders to improve the color strength and gloss of the paint. Process optimization requires the selection of the correct rotor geometry (i.e., saw-tooth), speed and time in order to achieve product quality.
High speed disperser design factors like rotor design (saw-tooth vs smooth), shaft stability, seal design, and body structure affect efficiency and product consistency. V-belt vs direct-drive systems, electric control boxes with speed control, and deck sealing affect product quality and consistency across batches.
The selection of a v-belt vs direct drive impacts torque, maintenance, and speed control priorities. V-belt systems absorb shock loads, are less expensive, and direct drive systems typically offer greater maintenance-free precision speed control.
The electric control box contains the safety interlocks, speed regulators, and motor controller, which allows the user to fine-tune rotor speed adjustments, as well as ramp-up and ramp-down sequences, and to execute emergency stop functions.
From a low to medium viscosity range, high speed dispersers offer excellent dispersion and pumping capabilities. However, for extremely high viscosity pastes, there may be a need to add other equipment or to alter the rotor geometry to avoid overloading.
