Why Precision Grinding Is Required
Coarse particles and poor dispersion in slurries directly degrade end‑product quality.
Ink IndustryUneven pigment dispersion in ink production causes batch color deviation. Inconsistent color across batches affects customer acceptance and printing quality. Three‑roll mill disperses pigments evenly to micron‑level, ensuring stable color consistency and tinting strength in mass production and reducing return risks. | Plastic IndustryPoor pigment dispersion in plastic color masterbatch results in color difference and low tinting strength, with obvious batch variations in large‑scale injection molding. Three‑roll grinding achieves uniform pigment dispersion to guarantee consistent color and tinting performance for continuous production. | Adhesive IndustryUneven filler dispersion in epoxy and silicone adhesives triggers viscosity fluctuation and inconsistent mechanical properties after curing. Batch variations in mass production influence customer acceptance. Three‑roll mill uniformly distributes fillers to maintain consistent viscosity and curing performance for large‑batch manufacturing. |
✨ ### Dilemmas of Traditional Grinding Equipment Small grinding devices feature insufficient capacity, requiring batch processing for large orders and resulting in low efficiency. Equipment without cooling functions suffers from accumulated heat during continuous high-volume operation, undermining product consistency. Ordinary grinding rollers deliver poor wear resistance, leading to frequent replacements, increased production costs and prolonged downtime.
Why Choose SIE‑SG120
Solve Core Pain Points for Medium‑Large Batch Continuous Grinding Production
Large Rollers for High CapacityThe rollers deliver large shearing area and high throughput with large single‑batch output, reducing grinding cycles for medium‑large‑batch continuous production. The 450mm long roller expands effective grinding zone to boost hourly capacity, meet mass‑delivery schedule and avoid time loss from split‑batch processing. Rollers are centrifugally cast chilled alloy cast iron (subject to actual product) with high surface hardness and wear resistance for heavy‑duty continuous production. | Temperature‑controlled Grinding with Heating & CoolingRoller heating reduces flow resistance of high‑viscosity materials to improve grinding efficiency. Cooling dissipates heat timely during continuous mass production to avoid heat buildup and guarantee batch‑to‑batch consistency. Adjustable temperature range fits diverse material processes. Stable temperature is critical for consistent quality in mass manufacturing. | Cooling‑water Circulation for Continuous OperationInternal water circulation channels inside rollers adjust cooling water flow via pipelines to suppress temperature rise caused by extrusion and friction during continuous heavy‑duty grinding. Rollers maintain good geometric condition to enhance grinding fineness and efficiency. Return water drains to sewer via water trough, ensuring consistent quality for successive batches. |
✨ SG120 is your ideal choice if you require continuous large‑batch grinding, temperature‑controlled batch consistency or high‑viscosity high‑throughput material processing.
Working Principle
It forces materials under compression and shearing via three rollers at different rotating speeds 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. 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.
