Why Precision Grinding Is Required
Coarse particles & poor dispersion impair final product quality.
Printing Ink IndustryCoarse pigment particles in lab ink formulas cause uneven hue and poor color development, undermining formula evaluation. Three-roll mill disperses pigments to micron level for uniform hue and reliable repeatable test data. | Cosmetics IndustryGritty texture in lipstick and foundation hurts smoothness and gloss. Three-roll milling delivers creamy paste, boosts product quality, and verifies end performance in small trial batches. | Electronic Slurry IndustryAgglomerated silver powder in conductive paste causes broken screen printing lines and unstable resistance. Three-roll mill evenly disperses silver powder for consistent printing and accurate lab formula tests. |
✨ Traditional grinding challenges: High-speed dispersers only disperse without real milling, failing fineness targets. Sand mills introduce impurities from worn media and contaminate valuable samples. Manual grinding is slow, inconsistent, and operator-dependent.
Why Choose SIE-SG80
Solve core pain points of small-batch grinding
Micron-level Precision GrindingPrecisely ground rollers with high parallelism and uniform gap across full length. Matte roller surface ensures good slurry adhesion. Roll ends are cold-pressed with heavy interference fit for solid connection. Repeated grinding achieves fine particle size to meet R&D fineness requirements. | Precise Speed Control by DC GovernorDC motor with adjustable speed, freely set according to material viscosity & target fineness. High speed for low-viscosity materials to boost efficiency; low speed for high-viscosity materials for uniform dispersion. Triangular belt and gear train drive rollers reliably for controllable grinding. | Compact Benchtop DesignIdeal for lab benchtop use. Small footprint, easy to move, fits limited lab space, no foundation required, ready after power-on. Removable feeding copper blade for easy cleaning and quick material changeover. |
✨ SG80 is ideal for small batches with temp grinding, frequent changeover or heat-sensitive materials.
Working Principle
Based on planetary motion principle
What other devices adopt planetary motion principle besides SG80?
Planetary ball mill operates on planetary motion principle. Grinding jars are mounted on the main sun disk. While the disk revolves around the central axis, grinding jars rotate rapidly on their own axes in the opposite direction.
Under this compound motion, grinding balls inside jars are subjected to alternating forces: Impact Force: Grinding balls are flung at high speed to crush coarse particles. Friction and Shear Force: High-frequency friction and shear between balls and jar walls realize fine grinding and dispersion. When centrifugal acceleration from revolution exceeds the critical value, balls are pressed against jar walls and rotate together with jars without effective grinding. Proper speed setting and transmission ratio are key to grinding efficiency. SIENOX models adopt optimized transmission ratios to achieve high centrifugal acceleration within valid speed ranges for efficient grinding. Typical Grinding Parameters: Sample Loading: ≤ 2/3 of jar volume (including grinding media and samples) Media Filling Ratio: 1/3 to 1/2 of jar volume Typical Grinding Time: 5–60 min (depends on material hardness and target fineness) Final Fineness: down to <0.1μm (varies with material, parameters and media selection) | ![]() |

How does the stirring and defoaming machine work?
The SIENOX stirring and defoaming machine performs defoaming through centrifugal force at revolution and stirring through shear force formed by revolution and rotation,
Assisted by a vacuum pump to extract gas and achieve a vacuum state, removing nanoscale tiny bubbles. No contact with materials, no secondary pollution, and no secondary waste.
-
What is the function of a defoaming machine?
A defoaming machine is a device used to remove bubbles from liquids. Its function is to assist in the liquid mixing, reaction, coating, printing, infusion and other process steps in the production process, avoiding the generation of bubbles and their impact on the final product. In many industrial and laboratory environments, removing bubbles is essential as they may have a negative impact on product quality, such as affecting surface tension and stability. Defoaming machines typically use various techniques such as vibration, ultrasound, centrifugation, etc. to achieve effective bubble removal. It has a wide range of applications, including but not limited to semiconductors, solar energy, optics, biotechnology, materials science, etc.
