Key Features & Highlights

Elevate your material processing capabilities with engineering designed for optimal reliability, precision, and longevity. This laboratory grinder is expertly crafted to deliver consistent, scalable results that directly translate to larger production lines, minimizing guesswork and maximizing your operational efficiency.

  • Exceptional Durability: The centrifugally cast chilled alloy iron rollers provide a formidable, impenetrable surface that effortlessly withstands the abrasive nature of tough ceramics and heavy, dense pigments.

  • Differential Speed Dynamics: By leveraging precise speed variations across the slow (32 rpm), medium (89 rpm), and fast (250 rpm) rollers, the machine generates immense shear stress, forcing even the most stubborn agglomerates to disperse evenly.

  • Scalable Output Architecture: Formulations perfected on this compact unit can be seamlessly transitioned to our larger industrial models, ensuring absolute structural consistency in your extensive commercial roll-outs.

  • Uncompromising Fineness: Achieve a reliable particle reduction down to 15 μm, resulting in a buttery-smooth texture that profoundly enhances the tactile and visual appeal of cosmetics and premium printing inks.


Material & Purity

Maintaining the absolute purity of your formulations is critical, especially when processing highly sensitive compounds where even microscopic contamination can completely ruin an entire batch. Our grinder is meticulously engineered to safeguard the chemical and structural integrity of your materials from the first pass to the last.

  • Standard High-Hardness Rollers: The default chilled alloy cast iron rollers (≥ HS70°) offer incredible resistance against abrasive wear, drastically reducing the risk of metallic shedding during intense, prolonged grinding sessions.

  • Zero-Metal Contamination Options: For industries demanding absolute purity, such as luxury cosmetics, advanced electronic pastes, and pharmaceuticals, we offer highly customizable alumina or zirconia ceramic rollers to replace the standard iron.

  • Sanitary Stainless Steel Chassis: The exterior and structural components can be tailored with premium stainless steel, providing a sleek, easy-to-sanitize surface that aggressively resists corrosion from harsh chemical solvents and acidic pigments.

  • Pristine Output Quality: By virtually eliminating cross-contamination and material degradation, your final product retains its intended vivid color profile, precise electrical conductivity, or delicate, nuanced scent profile.


Grinding Precision & Efficiency

Achieving a flawless dispersion in high-viscosity materials requires much more than just raw motor power; it demands microscopic precision. This equipment is perfectly calibrated to deliver uncompromising accuracy, ensuring that your research and development data is robust, repeatable, and ready for massive scaling.

  • Intense Shear Force Generation: The meticulously calculated differential speeds between the three 65 mm rollers create a powerful wiping and crushing action, systematically breaking down dense particle clusters without destroying the base material.

  • Targeted Fineness Control: Operators can reliably achieve a stable grinding fineness of 3-15 μm, with the advanced capability to reach sub-micron levels (below 1 μm) for specialized, high-end applications.

  • Optimized for R&D Environments: Specifically tailored for laboratory sampling and small-batch trials, the SM65 model offers a highly efficient processing capacity of approximately 5 kg per hour, maximizing daily testing output.

  • Seamless Scale-Up Guarantee: Every dynamic parameter is designed to mirror the performance of massive industrial units, guaranteeing that the flawless texture achieved in the lab will be perfectly replicated on the main factory floor.


Cooling & Temperature Control

High-viscosity friction inevitably generates substantial heat, which can quickly degrade heat-sensitive ingredients, alter delicate color profiles, or cause unwanted premature polymerization. Our advanced thermal management architecture ensures your materials remain cool, stable, and perfectly preserved throughout the entire milling cycle.

  • Hollow Roller Architecture: Each of the three horizontal rollers features a precision-engineered hollow core, allowing for maximum internal surface area contact with the cooling medium.

  • Integrated Water Cooling System: A continuous, highly efficient water circulation system rapidly draws destructive heat away from the grinding interface, maintaining a strictly controlled, optimal operating temperature.

  • Protection for Thermal-Sensitive Formulas: By actively preventing sudden heat spikes, the grinder protects the delicate chemical structures of premium UV inks, high-end skincare cosmetics, and active pharmaceutical ingredients.

  • Consistent Viscosity Maintenance: Stable processing temperatures prevent the material from thinning out or thickening unpredictably during the run, ensuring a uniform, homogenous paste from the exact start to the finish.


Operation & Adjustment

In a demanding, fast-paced laboratory setting, equipment must be intuitive, highly responsive, and exceptionally easy to maintain. We have designed this grinder with the professional operator in mind, integrating ergonomic controls and intelligent mechanisms that drastically reduce setup times and streamline the cleaning process.

  • Micro-Precision Gap Adjustment: Ergonomically designed handwheels allow operators to make ultra-fine, tactile adjustments to the roller spacing, granting absolute control over the final particle size and shear intensity.

  • Adaptive Discharge Scraper: The highly responsive, self-adjusting scraper blade maintains optimal, flush contact with the fast roller, ensuring maximum product recovery and a clean, continuous flow of the finished paste.

  • Rapid Disassembly and Cleaning: Recognizing the frequent material changeovers inherent in R&D, the structural layout permits quick access to the rollers and scraper, facilitating thorough sanitation without the need for specialized, cumbersome tools.

  • Smooth User Experience: The satisfying tactile feedback of the adjustment dials and the quiet, vibration-dampened motor operation create a refined working environment, allowing technicians to focus entirely on formulation optimization.


Industry Adaptability

Versatility is the absolute cornerstone of a smart equipment investment. Rather than being locked into a single, rigid application, this grinder is engineered to handle an incredibly diverse spectrum of high-viscosity compounds, making it an indispensable asset across multiple cutting-edge and traditional industries.

  • Traditional Chemical Processing: Effortlessly homogenizes heavy industrial paints, vibrant color pigments, and thick printing inks, ensuring brilliant color payoff and smooth, streak-free application.

  • Advanced New Materials: Delivers the extreme precision required for dispersing conductive lithium battery slurries, photovoltaic materials, and high-performance electronic adhesives without compromising their delicate structural integrity.

  • Cosmetics and Personal Care: Gently yet effectively refines luxurious lipsticks, rich cosmetic foundations, and dense soap bases, resulting in a silky, skin-pleasing tactile experience that consumers demand.

  • Food and Confectionery: Highly capable of refining dense organic pastes, including premium chocolates and nut butters, ensuring a velvety mouthfeel completely free of any gritty, unrefined residue.
