Triple Roller Mill (Three Roll Mill for High-Viscosity Ink, Paste & Slurry Grinding)
Product Overview & Operating Principle
The industrial triple roller mill (three roll mill) is a precision high-pressure grinding and dispersing machine engineered for processing ointments, heavy pastes, and high-viscosity slurries up to 3,000,000 cps. It consists of a heavy cast frame, electric drive motor, transmission gear set, scraping scraper assembly, hydraulic or manual gap adjustment mechanism, and three horizontally placed precision rollers rotating at differential speeds in opposing directions.
Mechanical Shear & De-agglomeration Dynamics
Grinding and dispersion are achieved through intense hydraulic shear forces and squeezing pressure generated in the narrow clearance gaps between the three rollers. As high-viscosity slurry passes through the feeding roller gap to the center and front rollers, differential tangential surface speeds break down agglomerates, dispersing pigment particles uniformly into resins and solvents. Large agglomerates continuously roll in a "rod-like" rotation at the gap inlet until reduced to particle sizes small enough to pass between the precision-ground roller surfaces.
Operator Safety & Emergency Braking Protection
Because a three roll mill exerts extreme mechanical nip pressure between rotating metal or ceramic barrels, operator safety is paramount. POLYC triple roller mills are fitted with prominent emergency brake buttons, safety nip guards, and foreign object trip sensors to prevent operator injury or mechanical damage if tools or foreign items enter the roller gap.
Complete Ink & Paste Production Line Integration
As part of a complete turnkey ink production line or heavy coating system, POLYC integrates the three roll mill alongside automated raw material handling, pre-dispersion, and downstream filling units:
1. Material Dosing & Feeding
- Powder dosing & loss-in-weight measurement
- Solvent & liquid resin dosing pumps
- Micro-additive dosing meters
2. Pre-Mixing & Milling
- High-shear planetary pre-mixers
- Precision three roll mill for pigment grinding
- Vacuum tinting & finishing kettles
3. Filtering, PLC & Auxiliaries
- High-viscosity extrusion discharge presses
- PLC central recipe control cabinets
- Chilled water recirculation & dust collection
Key Technical Advantages of POLYC Three Roll Mill
1. Extreme Viscosity Capabilities (≤ 3,000,000 cps)
Handles non-flowing pastes, offset printing inks, electronic silver/aluminum pastes, chocolate, dental compounds, and lithium battery slurries where traditional bead mills stall.
2. Precision Internal Roller Cooling (ΔT < 10°C)
Hollow steel or ceramic barrels feature continuous internal chilled water passage. Thermal rise during intensive shearing is strictly held below 10°C, preserving heat-sensitive resins and active ingredients.
3. Custom Ceramic Rollers (Zero Contamination)
Barrels can be crafted in high-purity Zirconia ceramics (ZrO²) or Aluminum Oxide (Al²O³) to prevent metallic ion contamination and color shifting in white or conductive pastes.
