Product Overview
The laboratory disperser and sand mill is a multifunctional system designed for wet grinding, dispersing, emulsifying, and homogenizing a wide array of materials including metals, non-metals, organics, and traditional Chinese medicine powders. Engineered for precision and repeatability, this unit excels in research and development environments where small-batch processing and process parameter exploration are critical. Utilizing the intense shear and impact forces generated by high-speed motion of grinding media within a cooled chamber, it rapidly breaks down agglomerates and achieves uniform particle size distributions down to the micron or sub-micron range.
Targeting industries such as paints, inks, coatings, advanced ceramics, battery materials, phosphors, and nanomaterials, this equipment provides the flexibility to simulate production-scale processes on a laboratory scale. Its dual capability—functioning as both a bead mill with an agitator and a high-shear disperser with a disc—eliminates the need for multiple pieces of equipment, saving valuable lab space and capital. Researchers can easily switch between grinding and dispersing modes by exchanging the tooling, making it ideal for formulation development and process optimization.
Built with a robust 0.37 kW motor, an integrated cooling jacket around the grinding chamber, and user-friendly quick-change clamping, the system ensures consistent, reliable performance even under continuous operation. The compact footprint and straightforward controls allow seamless integration into any lab setting, while the durable stainless steel contact parts guarantee corrosion resistance and easy cleaning. Whether processing abrasive ceramics or sensitive pharmaceutical powders, this disperser delivers dependable and reproducible results, backed by our commitment to quality manufacturing.
Key Features
- Simple & Ergonomic Design: The straightforward architecture of this disperser minimizes operator training and simplifies routine maintenance. All controls are logically arranged, and the grinding chamber is easily accessible for quick cleaning between batches, reducing cross-contamination risks.
- Quick-Change Tooling System: Featuring a tool-less quick-clamp chuck, the agitator and dispersing disc can be swapped in seconds without wrenches or disassembly. This design dramatically shortens changeover times, enabling a single operator to handle multiple formulations back-to-back.
- Integrated Cooling Jacket: The double-walled grinding chamber enables circulation of cooling water or other coolants, effectively extracting heat generated during intense milling. This prevents thermal degradation of temperature-sensitive samples and maintains consistent viscosity for accurate process simulation.
- Dual-Functionality in One Unit: By substituting the milling agitator with a high-shear dispersing disc, the same motor base performs bead milling and high-speed dispersion. This versatility supports a wide range of particle engineering tasks, from deagglomeration of nanoparticles to tinting of paint bases.
- Adjustable Dual-Speed Operation: The motor is configured with two preset speeds—1400 rpm for pre-mixing and gentle dispersion, and 2800 rpm for high-energy grinding and emulsification. This binary control paradigm eliminates variability yet covers most laboratory requirements with repeatable shear profiles.
- Broad Material Compatibility: Wetted parts are constructed from chemically resistant stainless steel, allowing safe processing of corrosive solvents, acidic/alkaline slurries, and abrasive ceramic suspensions. The system is validated for use with metals, non-metals, organics, and even traditional Chinese medicine herbs.
- Compact and Robust Construction: With a lifting stroke of 200 mm and a benchtop-friendly footprint, the unit fits easily into crowded laboratories. Despite its small size, the heavy-duty motor and precision bearings deliver industrial-level durability, making it a lasting investment.
Applications
| Application | Description | Key Benefit |
|---|---|---|
| Paints & Coatings Development | Formulation and testing of architectural, automotive, and industrial coatings. This disperser handles pigment grinding, filler dispersion, and additive incorporation with high reproducibility. Using small batch sizes, researchers can evaluate tinting strength, color development, and fineness of grind efficiently. | Uniform color development and consistent fineness enable accurate scale-up from lab to production, minimizing costly pilot trials. |
| Printing Ink Research | Milling and dispersing of various ink types including offset, flexographic, and inkjet formulations. The system accommodates low-viscosity fluids and high-pigment-load pastes, ensuring thorough wetting and deagglomeration of carbon black, organic pigments, and inorganic extenders. | Achieves target particle size distributions while maintaining consistent rheology, critical for print quality, drying speed, and storage stability. |
| Electronic Ceramics Processing | Preparation of thick-film pastes for MLCCs, PTC/NTC thermistors, and varistors. The unit produces homogeneous slurries for tape casting, screen printing, or spray drying, enabling precise control of layer thickness and electrical properties. | Ensures uniform dispersion of ceramic powders, minimizing defects and enhancing dielectric, piezoelectric, or semiconducting performance. |
| Battery Materials R&D | Grinding and dispersing of cathode materials (NMC, LFP, LCO) and anode materials (graphite, silicon) for lithium-ion batteries. The cooling jacket prevents overheating of sensitive materials, preserving crystal structure and avoiding unwanted side reactions during solvent-based processing. | Optimized particle morphology and uniform conductive additive distribution lead to improved electrode density, rate capability, and cycle life. |
| Phosphors & Luminescent Powders | Processing of rare-earth doped phosphors, long-persistence glow powders, and polishing abrasives. The gentle dispersion action preserves fragile host lattices while achieving narrow particle size distributions necessary for consistent luminescence. | Maintains high quantum efficiency and afterglow duration by avoiding mechanical damage to activator sites, essential for display and lighting applications. |
| Advanced Nanomaterial Synthesis | Deagglomeration and stabilization of nanoparticles (silica, titania, carbon nanotubes) in liquid media. The high-shear disc overcomes strong van der Waals forces, and the cooling jacket prevents heat-induced re-agglomeration during prolonged processing. | Produces stable nano-dispersions with narrow size distribution, crucial for tailoring optical, mechanical, or electrical properties of nanocomposites. |
| Piezoelectrics & Dielectrics R&D | Mixing and grinding of PZT, BaTiO₃, and other functional oxide powders for sensors, actuators, and energy harvesters. The mill's high impact forces effectively break down hard agglomerates, while the stainless steel chamber avoids metallic contamination. | Achieves high-density green bodies and uniform microstructure upon sintering, critical for reproducible piezoelectric coefficients and dielectric constants. |
| Traditional Chinese Medicine Grinding | Ultra-fine pulverization of dried herbs, roots, and minerals for pharmaceutical research. The enclosed system minimizes dust and cross-contamination, and the cooling jacket preserves heat-sensitive phytochemicals during size reduction. | Preserves bioactivity while achieving particle sizes below 50 microns, enhancing extractability, bioavailability, and formulation homogeneity. |
