Why Precision Grinding Is Required
Coarse particles and poor dispersion in slurry will directly affect the quality of end products.
Ink Printing IndustryCoarse pigment particles in newly formulated laboratory inks cause uneven hue and poor color development, affecting the accuracy of formula evaluation. Three-roll milling disperses pigments to micron level, ensuring uniform hue and excellent color development for reliable and reproducible formula test data. | Cosmetics IndustryVisible graininess in pastes such as lipsticks and foundation impairs spreadability and gloss, resulting in poor consumer experience. Three-roll milling delivers smooth and fine paste, improving product texture and market competitiveness. End-product performance can be verified through small-batch trial production. | Electronic Slurry IndustryAgglomerated silver powder in conductive silver paste causes screen printing breakpoints and sheet resistance fluctuation, undermining performance consistency of electronic components. Three-roll milling uniformly disperses silver powder to guarantee continuous screen printing and stable sheet resistance for more accurate laboratory formula evaluation. |
✨ Dilemmas of traditional grinding: High-speed dispersers commonly used in laboratories can only disperse materials instead of performing real grinding, failing to meet fineness requirements; the worn grinding media of sand mills introduce impurities and contaminate precious small samples; manual grinding features low efficiency and poor consistency, and results vary between different operators for the same material.
Why Choose SIE-SG50
Solve Core Pain Points of Laboratory Small Sample Grinding
Micron-level Precision GrindingThe roller surface undergoes precision grinding treatment with high parallelism, maintaining consistent gap clearance along the full length of rollers. The matte roller surface enables good adhesion of slurry. The shaft heads at both ends of the barrel adopt heavy interference cold pressing technology for firm and stable fitting with the barrel. Repeated circulating grinding achieves finer particle size to meet strict fineness requirements in the R&D stage. | Precise Speed Control with DC Speed RegulatorThe DC motor is equipped with a speed regulator for adjustable rotating speed. The grinding speed can be flexibly set according to material viscosity and target fineness. High-speed grinding improves efficiency for low-viscosity materials, while low-speed grinding ensures uniform dispersion for high-viscosity materials. The motor transmits power to the drive shaft via V-belt, and the gear train sequentially drives fast roller, middle roller and slow roller. Stable and reliable transmission ensures precise and controllable grinding every time. | Compact Benchtop DesignDesigned for laboratory benchtop operation. Small footprint and easy movement, allowing flexible layout in limited space of R&D laboratories. No special foundation installation required; ready for use once powered on. The feeding copper blade can be removed for easy cleaning and convenient material switching. |
✨ If your laboratory needs a compact, easy-to-operate three-roll mill with micron-level grinding fineness, the SG50 is the ideal choice.
Working Principle
Three rollers rotating at different speeds force the material under compression and shear to achieve mixing and homogenization.
Step 1: Three-roll Shear Grinding Step 2: Particle Size Control by Gap Adjustment Step 3: Material Collection by Scraper Simple three steps: Three-roll shearing → Gap particle control → Scraper discharging, stepwise grinding down to 3-18μm. A cold water circulation channel is arranged inside the rollers. The water flow is adjusted through cooling water pipes to suppress temperature rise during dispersion and guarantee grinding quality. | ![]() |
