Electronic Digital Laboratory Three Roll Mill
Laboratory three roll mill is compact desktop lab equipment for small-batch wet grinding and homogenization of high-viscosity pastes. Three differential-speed rollers create strong shear force to disperse pigments and solid particles evenly. Equipped with adjustable roller gaps and emergency stop for safe operation, it suits cosmetics, inks and electronic slurries in R&D labs. The lab three roll mill delivers precise, repeatable test results with easy cleaning and stable running performance for formula development.

Ultra-Small Sample CapabilityThe SDS series electronic control laboratory three roll mill model is engineered for precision processing of powders in liquid and highly viscous suspensions, delivering dispersion, deagglomeration, homogenization, and defoaming. Suitable for electronics, printing inks, pigments, cosmetics, PVC pastes, and silicone industries, these lab three roll mill systems support modular configurations to meet customized production requirements, whether for small-scale laboratory testing or larger pilot-scale applications.
● Multi-material roller system: Standard alloy steel rollers with optional zirconia/alumina ceramic materials, ensuring versatility for various materials processed in both laboratory three roll mill and industrial settings.
● Intelligent control platform: Touchscreen interface supports parameter memory and speed ratio adjustment, allowing precise control in both lab three roll mill and production-scale mills.
● Thermal management module: Optional automatic circulating chilling unit simplifies cooling while serving as an operational platform, which is crucial for maintaining consistent performance in laboratory three roll mill operations.
● Compact industrial design: Optimized structural layout enhances space utilization efficiency, making these mills ideal for both lab three roll mill environments and production floors where space is at a premium.


In modern material science laboratories, developing nanomaterials or expensive electronic inks requires extreme precision. Traditional mechanical lab mills cannot provide the quantifiable, recordable data needed to scale up a formulation from the lab to mass production safely.
The SDS Series laboratory three roll mill is an electronic, CNC-controlled marvel designed specifically for the laboratory. Starting with models capable of processing as little as 0.02 Liters/hour, it features highly sensitive electronic gap adjustments and full digital monitoring. It allows R&D teams to map out the exact parameters required for perfect dispersion, ensuring seamless scalability.

Replaces manual handwheels with high-precision stepper/servo motors. Adjust roller gaps down to the micrometer level via the touchscreen interface on the laboratory three roll mill, ensuring unparalleled fineness for advanced formulations.

The highly optimized roller design (as small as 50mm diameter on the SD50) of the lab three roll mill allows for the processing of ultra-small, highly expensive experimental batches with virtually zero dead-volume or material waste.

Record exact operational data—including roller speed, gap distance, and temperature—to create a "digital twin" of your process, enabling a mathematically flawless scale-up to our production-sized SYS machines.
