Shanghai Polyc Technical Analysis of High-Shear Inline Dispersing Machine and Industrial Solutions
1. Introduction of Inline Dispersing Machine: The Shift from Batch to Inline
In the modern chemical processing landscape, the transition from traditional batch mixing to Continuous Inline Dispersion represents a significant leap in manufacturing efficiency. Inline high-shear dispersers are engineered to handle homogenization, emulsification, and de-agglomeration with extreme precision, serving as the "heart" of production lines for coatings, new energy materials, and fine chemicals.
Existing paint and coating chemical manufacturers often focus on the grinding machine process in order to achieve the final fineness, neglecting the dispersion process in the early stage, which also plays a 50% role in the final result. Shanghai Polyc is committed to researching dispersion processes to reduce the burden of grinding processes and help achieve better grinding results.
Traditional dispersion: When customers use traditional dispersion, all raw material powders are introduced into the liquid, and the powder has already agglomerated, making it difficult to fully wet the inside, and even forming large particles that sink to the bottom of the liquid. The second step only disperses, the effect is not good, and the efficiency is very low.
POLYC Inline Dispersion Effects: Using Polyc Inline dispersing machine, wetting between primary particle when powder contact liquid beforedispersion.
Then the dispersed initial powder particles have been sheared into separated primary particles and particle fragments, making it easier for the particles to mix with the liquid. Better effect and higher efficiency.
3.Working principle of Polyc High Shear Inline Dispersing Machine:
Polyc conducts year-round research on fluid dynamics and energy density. Adopting "vacuum assisted wetting", which means that the powder is directly introduced into the high shear zone under vacuum to prevent air entrainment. And design high-throughput reliability and intelligent control systems to ensure very narrow particles (1-5um), sub micron or nanometer range (<100nm).
Working Principle:
Featuring an advanced rotor-stator design, the inline disperser generates ultra-high shear force to achieve nano-level precision dispersion, making it particularly suitable for demanding homogenization processes. Its in-line operation mode allows direct integration into existing pipeline systems, significantly enhancing production efficiency while ensuring product quality consistency.
Customizable pipeline ports, with one end for powder suction and the other end for liquid/powder inlet, dispersing and circulating multiple times together with the liquid in the kettle.

4.Problems Associated with Handling Powders of Traditional Dispersion:
- Environmental contamination
- Potential risk to operator health
- Exhaust systems and filters are necessary
- Filters require regular servicing and have to be disposed
- Dust masks & protective clothing are common
5.Advantages of Polyc High Shear Inline Dispersing Machine:
- Powder induction, wetting, dispersion and dis-agglomeration in one stage, Dispersion quality improved and 2/3 of milling time reduced.
- Reduce dust pollution and promote environmental protection.
- Less powder handling equipment.
- Reduce the grinding time of traditional grinding machines, much higher capacity per square foot factory space and achieve the target fineness.
- Reduce the electricity used by grinding machines to help factories save production costs. Energy saving more than 50%.
- Reduction of production costs, production time, batch changing and higher productivity.
- Reduction of thickeners, defoamers and wetting agents.
- Flexible, variable batch sizes and easy for colour changing
- Movable can be design mounted on a skid suitable to small batch production.
- Maintenance Low:no grinding media to wear out or replace. High; requires media management and separation.
- Cleaning (CIP) Simple:fully pipe-integrated and self-pumping. Complex; high material residue and long downtime.
6. Strategic Solutions for Industrial Pain Points
Solution A: The "Zero-Dust" Automated Induction System
Target Pain Point: Hazardous dust clouds and uneven wetting during manual powder charging.
Technical Solution: Integration of a Vacuum Powder Induction Port directly into the inline disperser’s inlet. The high-speed rotation creates a local vacuum, drawing powder directly from a silo into the liquid stream. This ensures instantaneous wetting and a dust-free environment.
Solution B: High-Viscosity De-agglomeration for Battery Slurry
Target Pain Point: Agglomerates in Lithium-ion battery slurry (e.g., CNT or Carbon Black) causing electrode defects.
Technical Solution:Multi-Stage High-Shear Inline Systems (Triple Stator-Rotor sets). Material is forced through three successive shear zones with decreasing tolerances. This ensures 100% of the slurry is processed, eliminating "fisheyes" and ensuring uniform conductivity.
Solution C: Anti-Corrosive and Anti-Wear Design for Pigment Production
Target Pain Point: Rapid wear of stainless steel components and metal contamination in high-purity pigments.
Technical Solution: Customization of contact parts withTungsten Carbide (WC) coatings or Zirconia (ZrO₂) ceramics. Coupled with integrated temperature-controlled cooling jackets, this solution prevents thermal degradation and extends equipment lifespan by 5–8 times compared to standard SS316L.
7. Conclusion
The high shear inline disperser developed by Shanghai Polyc is not just an equipment upgrade; Polyc is more committed to helping customers achieve intelligent manufacturing, improve efficiency, reduce costs, and expand production scale.
