The Laboratory Powder Mixing Homogenizer is a high-performance lab-scale device specifically engineered for ultra-fine blending of powdered materials across various industries. It integrates three core technologies—high-speed crushing, precision shearing, and multi-directional collision—to break down material agglomerates and ensure uniform particle distribution. This synergy enables it to achieve homogeneous mixing with particle uniformity exceeding 98% within just 3-15 minutes (depending on material type and batch size), far outperforming traditional static mixers. Crafted with SUS 304 stainless steel for all material-contact parts, the device not only offers excellent corrosion resistance and easy cleaning but also fully complies with GMP (Good Manufacturing Practice) standards, as well as FDA and CE certifications, making it a reliable choice for precision-critical industries like pharmaceuticals and food processing. With a compact footprint of 600×1000×1000mm (for the smallest benchtop model) and a modular design that supports optional accessories (such as temperature sensors and dust-collection hoods), it fits seamlessly into laboratory workflows—whether placed in a fume hood, on a standard lab bench, or integrated with other lab equipment (e.g., analytical balances, drying ovens) for continuous processing.

100G | 220V | 700W | 25000 r/min | 80-250 mesh | 7kg | 26*26*40mm |
200G | 220V | 900W | 25000 r/min | 80-250 mesh | 8.5kg | 28*28*40mm |
300G | 220V | 1100W | 25000 r/min | 80-250 mesh | 10kg | 30*30*45mm |
Dual Motion Technology: Combines 3D barrel rotation (adjustable from 0-20 rpm) and high-speed rotor shearing (driven by a brushless DC motor) to eliminate even stubborn agglomerates. The 3D barrel rotation ensures no dead zones in the mixing chamber, while the shearing rotor—coated with wear-resistant tungsten steel—generates a strong vortex that pulls materials into the center for thorough blending.
Wide Viscosity Adaptability: Handles materials with viscosities ranging from low-density powders (e.g., talcum powder) up to 5000 mPa·s (near-paste-like materials, such as medicinal ointment powders or high-concentration ceramic slurries). It supports customizable working heads with diameters of 8-24mm: smaller heads (8-12mm) are ideal for fine powders (e.g., API powders), while larger heads (18-24mm) suit coarse granules (e.g., mineral powders).
Precision Control: Features an adjustable speed range of 13,000-34,000 rpm with 6-gear mechanical regulation, plus a digital display for real-time speed monitoring. Each gear corresponds to optimized parameters for specific material properties: low gears (13,000-18,000 rpm) prevent dusting of light powders (e.g., milk powder), while high gears (28,000-34,000 rpm) ensure thorough mixing of dense, high-viscosity materials.
Easy Maintenance: All detachable components (working heads, mixing chamber lid, sealing gaskets) support quick disassembly without tools. The working heads are compatible with autoclave sterilization at 120°C/0.1MPa for 20 minutes, meeting the strict sterility requirements of pharmaceutical and food labs. Additionally, the device uses food-grade silicone gaskets that resist high temperatures and chemical corrosion, reducing the need for frequent replacement.
Safety Design: Equipped with a servo-controlled lid that locks automatically once operation starts—any attempt to open the lid during mixing triggers an immediate shutdown. It also includes dual safety protections: an overload protection system (cuts power if motor load exceeds 120% of rated capacity) and an overheat protection (activates at 60°C to prevent motor damage).
Energy Efficiency: Offers 0.25kW (benchtop), 0.8kW (small-scale), and 1.5kW (medium-scale) motor variants, all designed with energy-saving copper windings. Compared to conventional belt-driven mixers, it reduces power consumption by 30%—for example, blending 10L of ceramic powder requires only 0.6kWh with this device, versus 0.85kWh with traditional models.
Pharmaceuticals: Ideal for blending active pharmaceutical ingredients (APIs) with excipients (e.g., lactose, microcrystalline cellulose) in tablet/capsule formulation, as well as pre-mixing vaccine powders and antibiotic fine powders to ensure dose uniformity.
Advanced Materials: Used in preparing ceramic slurries (for electronic components like capacitors) and battery electrode composites (e.g., lithium-ion battery cathode powders mixed with conductive carbon black), where particle homogeneity directly impacts product performance.
Food Science: Suitable for homogenizing protein powders (e.g., whey protein, soy protein), nutritional supplements (e.g., vitamin blends), and functional food ingredients (e.g., probiotic powders mixed with maltodextrin to protect viability).
University laboratories: Supports material composition optimization experiments, such as testing the impact of mixing parameters on the performance of new composite materials (e.g., graphene-reinforced polymer powders).
Quality control labs: Enables batch consistency testing for industries like cosmetics (e.g., verifying pigment powder uniformity in mineral foundation) and pesticides (e.g., ensuring active ingredient distribution in powder formulations).
Pilot-scale production: Serves as a bridge between lab research and mass production, allowing enterprises to test mixing processes on a small batch (50-200L) before scaling up, reducing trial-and-error costs.
Q: What is the maximum batch capacity, and which materials are optimized for the bulk density of 0.6g/cm³?
A: The batch capacity ranges from 4.5L (benchtop model, ideal for lab-scale trials) to 1800L (medium-scale model, suitable for pilot production). The bulk density optimization of 0.6g/cm³ targets common lab materials such as lactose powder, calcium carbonate powder, and talcum powder—materials with higher bulk density (e.g., metal powders, ~1.2g/cm³) may require slight adjustments to mixing time (extended by 2-3 minutes) for optimal uniformity.
Q: Can it process heat-sensitive powders, and what measures are taken to prevent thermal damage?
A: Yes, it is specially designed for heat-sensitive materials like enzyme preparations, probiotic powders, and vitamin blends. The low-friction structure (using self-lubricating PTFE bearings) minimizes heat generation, keeping the mixing chamber temperature ≤40°C during operation. For extremely heat-sensitive materials (e.g., live vaccine powders), an optional built-in air-cooling system can further lower the temperature by 5-8°C, ensuring material activity is not compromised.
Q: How long does screen replacement take, and is there a way to verify sealability after replacement?
A: Tool-free disassembly allows working head (screen) changes in 3-5 minutes—simply twist the locking ring to remove the old head and install the new one. After replacement, a built-in pressure test function can be activated: the device inflates the mixing chamber to 0.05MPa and monitors pressure for 1 minute; if no pressure drop is detected, the seal is confirmed to be intact, preventing material leakage or cross-contamination.
Q: Is calibration required, and what does the calibration process involve?
A: The device is factory-calibrated before delivery, but annual recalibration is recommended for precision-critical applications (e.g., pharmaceutical API mixing). Calibration includes two key items: 1) Speed accuracy: Using a laser tachometer to verify that the actual rotor speed matches the displayed speed (tolerance ≤±2%); 2) Mixing uniformity: Blending a standard test powder (e.g., red dye powder + lactose) and testing 5 random samples to ensure uniformity ≥98%. The manufacturer offers optional on-site calibration services or a mail-in calibration program for convenience.
