Product Details

Driven by the rapid advancement of emerging industries including new materials, new energy, high-end electronics, biomedicine and cosmetics, the demand for preparing slurries with high precision and narrow particle size distribution keeps rising. Restricted by structural design and control accuracy, conventional grinding equipment fails to meet stringent requirements for nanomaterial dispersion, homogenization of precious metal slurries and stability of functional ceramic slurries.

Changzhou Longxin Intelligence launches the Superfine precision three-roll mill series. Custom-built for ultra-precision grinding and dispersion, it bridges the technical gap covering laboratory research, pilot scale-up and mass production, serving as indispensable core equipment for the preparation of high-performance materials.

Equipment Upgrade Powered by High-precision, Intelligent and Flexible Manufacturing

Products such as conductive silver paste, solar electrode slurry, carbon nanotube dispersion liquid, dental ceramics and functional cosmetics require micron and even submicron level standards for particle size distribution and dispersion stability. Clients focus not only on final product performance, but also process reproducibility, parameter traceability and easy operation.

R&D features small-batch production, diverse formulas and rapid iteration, which demands outstanding equipment flexibility. Pilot and small-scale manufacturing calls for balanced processing efficiency and grinding precision. Tailored to such market demands, the Superfine series enables seamless connection among research, testing and production.

Working Principle: Three-roll Shearing & Extrusion Dispersion for Efficient Deagglomeration

Adopting the classic three-roll differential speed operation mechanism, the Superfine precision three-roll mill receives materials into the gap between the front and middle rollers. Initial dispersion is achieved under intense shear force generated by high-speed rotation.

Materials then pass through the narrower gap between middle and rear rollers, undergoing secondary shearing and extrusion driven by larger linear speed difference. Hard agglomerates are fully crushed to refine particles and achieve even distribution.

With accurate control over roller speed ratio and inter-roller gap (minimum below 1μm), the grinding intensity can be adjusted at micron and submicron levels, delivering discharged slurry with superior dispersibility, stability and narrow particle size distribution.

Equipment Structure: Modular, Compact & Human-machine Collaborative Design

The Superfine series features highly integrated and modular construction. Compact in size, it fits standard laboratory benches to save floor space.

Core components:

High-rigidity frame: Maintains long-term parallelism of rollers and prevents gap deviation caused by mechanical deformation.
Precision gap adjusting mechanism: Available with manual mechanical adjustment or high-precision servo-driven electric regulation system, supporting real-time dynamic correction.
Adaptive scraper system: Elastic tension structure keeps constant pressure contact with roller surfaces, minimizing frequent adjustment and enhancing operational stability.
Optional circulating cooling system: Effectively controls grinding temperature rise and avoids deterioration of heat-sensitive materials.
Comprehensive safety protection: Equipped with dust cover, emergency stop and reverse cleaning mode for reliable operation safety.

Technical Parameters

Performance Features: Integrated Precision, Intelligence and Reliability

The Superfine series boasts six core performance strengths:

Ultra-high grinding precision: The minimum discharge particle size can reach below 1μm subject to material properties, far exceeding conventional equipment.
Dual-mode intelligent control: Freely switch between gap mode and pressure mode, with real-time display of set values and actual stress feedback.
Diversified material compatibility: Rollers available in stainless steel, alumina, zirconia, silicon carbide and more to meet diverse chemical compatibility requirements.
Easy cleaning and maintenance: Finely polished roller surface paired with reverse cleaning function greatly shortens material replacement and cleaning time.
Formula-based operation: Preset and recall process parameters to improve test repeatability and production consistency.
IoT intelligent upgrade: Supports remote monitoring, data acquisition and authority management. It can connect with online viscometers, particle size analyzers and other testing devices to build an intelligent grinding workstation.

Technical Upgrade: Evolution from Equipment to Professional Platform

Compared with traditional three-roll mills, the Superfine series achieves remarkable technological advancement:

Intelligent control: Desktop equipment is equipped with electronic gap adjustment, formula storage and process recording functions previously only applied on large-scale production machines.
Interactive operation: Graphical touch interface simplifies operation, enabling technicians to shift role from operators to process designers.

More than just grinding machinery, Superfine precision three-roll mill serves as an enabling platform for high-performance material R&D and manufacturing. Driven by continuous technological innovation, Changzhou Longxin Intelligence helps clients break process barriers in new nanomaterials, electronic slurries and functional coatings, realizing development from basic production to premium quality and precise controllability.
