The classic three roll mill is a classic grinding and dispersing device for high-viscosity pastes. It relies on three rollers rotating at different speeds to generate strong shear force, refining inks, coatings, cosmetics and ointments evenly. With sturdy alloy rollers and water cooling structure, the classic three roll mill delivers stable fineness and easy cleaning. Widely adopted in chemical, cosmetic and electronic paste production, it remains a reliable standard equipment for small-batch fine processing.
Robust Mechanical StructureManual Handwheel Gap AdjustmentIntegrated Cooling Water SystemThis classic three roll mill is engineered for powders with poor adhesion and drop-off tendency (e.g. guar gum, soap granules, ganoderma spores). Its innovative vertical roller alignment enables a dual-stage grinding process: materials enter from the top slow roller, undergo initial grinding at the intermediate roller, then automatically cascade to the fast roller for secondary refinement. This unique workflow guarantees complete grinding cycles even with material fall-off, while the bottom discharge design minimizes dust emission. Customizable as hydraulic-driven or manual-operated versions with conveyor integration, this patented classic three roll mill technology enhances viscosity in specialized materials like guar gum.
The Foundation of Consistent Dispersion
For decades, standard three roll mills have been the workhorse of the pigment and coating industries. However, finding a machine that maintains roller parallel accuracy over years of heavy use can be challenging.
The Zeelinal SG Series classic three roll mill provides a time-tested, purely mechanical solution. Built with a heavy-duty frame and precisely machined rollers, it allows operators to manually dial in the exact gap required for standard inks, paints, and basic chemical pastes. It is the ultimate choice for reliable, cost-effective milling.
Precision Handwheel Adjustment
Classic three roll mill equipped with ergonomically designed handwheels, allowing experienced operators to manually control the roller gaps with tactile precision.
High-Quality Cast Rollers
Manufactured with chilled cast iron or optional alloys to ensure high wear resistance and excellent thermal conductivity during the milling process, the classic three roll mill is built to deliver reliable, consistent performance.
Continuous Cooling System
Built-in internal water cooling channels inside the rollers prevent overheating, protecting sensitive materials from thermal degradation.

The SG series classic three roll mill handles standard to medium viscosity well. For extremely high-viscosity materials, we recommend our SGQ High Strength series.
In the classic three roll mill, temperature is managed by adjusting the flow rate of the cooling water passing through the internal roller channels.
Our classic three roll mill handles paint, ink, cosmetic paste and slurry. Its adjustable roller gap ensures uniform grinding, easy operation and stable production for daily industrial mixing tasks.
The classic three roll mill adopts precise transmission bearings to lower operation noise. With sealed gear structure, its running sound meets industrial standards and will not cause noise pollution in workshops.
The detachable rollers of classic three roll mill simplify full cleaning. No material residue stays in gaps, and you only need water or solvent to wipe surfaces for quick switch of different raw materials.
