Lab sand mill is a compact wet grinding device tailored for small-batch lab research, widely used for dispersing and refining pigments, inks, battery slurries and pharmaceutical raw materials.Featuring a mini grinding chamber, low power consumption and easy disassembly, it delivers stable, repeatable test data. The lab sand mill supports precise speed and temperature control with built-in cooling and safety protection, perfectly simulating industrial grinding processes to guide mass production parameter setting for labs, universities and R&D centers.
Micro-Volume ProcessingExact Production Scale-up DataVariable Frequency SpeedThe LS basket lab sand mill is engineered for small-batch production, integrating pre-dispersion and grinding within a single paint slurry tank. Its minimalist auxiliary configuration delivers three key operational advantages:
● Variable-speed spindle control: Enables smooth operation with low noise emission for the lab sand mill
● Efficient color change procedure: Streamlined auxiliary structure accelerates color switching on the lab sand mill
● Simplified maintenance: Significantly easier equipment cleaning and grinding media replacement
Perfect Your Formula Before Full-Scale Production
Developing a new advanced material, such as a conductive ink or nano-coating, is incredibly expensive. Running experimental trials on massive 50-Liter production machines wastes thousands of dollars in raw materials and grinding media.
Our lab sand mill is designed specifically for Research & Development. Offering both a 1-Liter horizontal model (ZLWS1) for continuous flow testing and a 3-Liter basket model (LS) for small batch testing, this professional lab sand mill replicates the exact shear forces of our industrial lines. You can formulate, test, and perfect your recipe with minimal material, capturing the exact data needed for a flawless scale-up to mass production.
Ultra-Low Minimum Volume
The ZLWS1 horizontal chamber of the lab sand mill allows for the continuous processing of very small lab samples, ensuring highly valuable active ingredients are not wasted in system dead-space.
Precision Variable Speed
Equipped with variable frequency drives (VFD), this lab sand mill allows researchers to test exactly how different RPMs and shear rates affect particle size distribution.
Interchangeable Material Options
Chamber and agitator components can be customized with high-purity Zirconia, Polyurethane (PU), or hard alloys to prevent any cross-contamination in sensitive chemical formulations.

Yes. Our lab sand mills are geometrically scaled down from our industrial models. The energy density and peripheral speeds are mathematically matched, ensuring your R&D results scale up predictably.
While they are small, models like the ZLWS1 utilize a robust 4kW motor to replicate industrial forces. They typically require a stable 3-phase power connection standard in most industrial testing facilities.
Our lab sand mill achieves ultra-fine grinding down to 0.1μm. It adopts small grinding beads, adjustable rotation speed, ideal for lab formula test of coatings, inks and pigments with stable grinding effect.
The lab sand mill is equipped with detachable grinding chamber and quick disassembly structure. Residues can be fully rinsed within 10 minutes, preventing cross-contamination for multi-formula lab experiments.
We supply 0.2L, 0.5L and 1L standard lab sand mill tanks. Small volume design matches lab small-batch trials, with low material consumption to cut your raw material test cost effectively.
