Why Must Microbubbles in Materials Be Eliminated?

Coarse particles and uneven dispersion in slurry directly affect end-product quality.

Ink Printing Industry

Coarse pigment particles in newly formulated laboratory ink cause uneven hue and poor color development, reducing the accuracy of formula evaluation. Three-roll milling disperses pigments to micron level to ensure uniform hue and excellent color rendering, delivering reliable and reproducible formula test data.

Cosmetics Industry

Obvious graininess in pastes such as lipstick and foundation ruins the spreading feel and gloss, leading to poor consumer experience. Three-roll milling produces fine and smooth paste to improve product texture and market competitiveness. End-product performance can be verified through small-batch trial production.

Electronic Slurry Industry

Silver powder agglomeration in conductive silver paste causes screen printing breakage and sheet resistance fluctuation, impairing performance consistency of electronic components. Three-roll milling achieves uniform silver powder dispersion, guarantees continuous screen printing and stable resistance, and enables more accurate laboratory formula evaluation.

✨ Dilemmas of traditional grinding: High-speed dispersers commonly used in labs only disperse instead of performing real grinding and fail to meet fineness requirements; sand mills introduce impurities from worn grinding media and contaminate precious samples; manual grinding features low efficiency and poor consistency, and results vary between operators for the same material.

Why Choose SIE-SG80

Solves core pain points of small-batch grinding production

Micron-level Precision Grinding

The rollers are precisely ground with a highly parallel surface, ensuring consistent gap clearance along the entire roller length. The matte roller surface enables excellent material adhesion. Both ends of the roller adopt heavy interference cold press fitting for sturdy and stable connection. Repeated circulating grinding achieves finer particle sizes, meeting strict fineness requirements for R&D applications.

Precise Speed Control with DC Governor

Equipped with a DC motor and speed governor, the machine supports adjustable rotating speeds to flexibly match 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. Power is transmitted via V-belt and gear system to drive fast, medium and slow rollers stably, realizing precise and controllable grinding every time.

Compact Tabletop Design

Designed for laboratory tabletop use. It features small footprint and easy movement, suitable for flexible layout in limited laboratory spaces. No professional foundation installation is required, and the machine is ready for use after power-on. The detachable feeding copper blade allows easy cleaning and fast material switching.


✨ If you need temperature-controlled grinding, frequent grade changeover or heat-sensitive material processing for small-batch production, SG80 is your 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
The motor inside the base transmits power to the drive shaft via V-belt. The drive shaft gear drives the fast roller gear, then the fast roller gear drives the middle roller gear, and the middle roller gear drives the slow roller gear, forming a complete transmission system. The three rollers rotate oppositely at a speed ratio of 1:2:4. The slurry is subjected to forced compression and shearing in roller gaps, and is ground and dispersed step by step from the slow roller to the middle roller and then to the fast roller.

Step 2: Particle Size Control by Gap Adjustment
Turn the handwheel to compress or release the spring, so as to move the fast and slow rollers back and forth to adjust roller gaps and control grinding fineness. The slurry is refined step by step from the feeding roller to the middle roller and then to the discharging roller. Various particle sizes of ground materials can be obtained by adjusting roller gaps via the handwheel.

Step 3: Material Collection by Scraper
A scraper blade is mounted on the upper edge of the discharge blade holder. The blade closely fits the fast roller surface with the fitting position slightly above the roller center. It smoothly scrapes and collects refined materials attached to the fast roller. Repeated circulating grinding can be performed until the target fineness is achieved.


Simple three steps: Three-roll shearing → Gap particle control → Scraper discharging, stepwise grinding down to 3-18μm. Cold water circulation channels are built inside rollers. The water flow is adjusted through cooling pipes to suppress temperature rise during dispersion and guarantee grinding quality.

  • 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.
