Core Technology & Working Principle
Ink at high viscosity does not behave like paint. It will not pour, so each stage moves it in a different way: a planetary mixer folds and de-aerates it, a hydraulic press forces it out of the tank, the roller mill shears it between rollers, and the filler meters it into the package.
▲ Vacuum Planetary Kneading
Twin twist-blades rotate on their own axis while orbiting the tank. Dry pigment is folded into the thick resin base under deep vacuum, which also removes entrapped air.
▲ Hydraulic Paste Evacuation
At this viscosity the paste cannot drain by gravity. A hydraulic platen lowers into the tank and extrudes the paste through the bottom valve into the mill.
▲ Triple Roller Nip-Shear Milling
The mixed paste is pulled through the micron-scale gaps between three differential-speed rollers. The shear crushes pigment agglomerates to the fineness the ink needs.
Precision Engineered Details
Three parts of the line decide whether the batch comes out uniform: the vacuum seal on the mixer, the sealing of the press platen, and the roller gap setting on the mill.
PTM Triple Roller Mill Technical Parameters
The roller mill is the core milling stage of the line. The table lists the four PTM models offered for ink production.
| Model | Roller Diameter (mm) | Working Length (mm) | Main Power (kW) | Total Weight (kg) |
|---|---|---|---|---|
| PTM-150 (Lab) | 150 | 300 | 2.2 | 500 |
| PTM-260 | 260 | 675 | 7.5 | 2,000 |
| PTM-406 | 406 | 810 | 15 | 5,300 |
| PTM-406L | 406 | 1000 | 22 | 5,800 |

Our Manufacturing Advantages
🏢 Direct Source Factory
Shanghai Polyc Technology Co., Ltd. is not a reseller. Every ink production line is machined, assembled and tested at our Wuxi plant, so you buy at the factory price and speak directly to the engineers who built it.
✈️ 30–45 Days Fast Delivery
Standard models ship in 30–45 days from confirmed drawings, thanks to our integrated vertical in-house production lines.
🛡️ Strict Quality Control
Key welds, seals and running accuracy are inspected before assembly, and each machine is run at the factory before packing.
🔧 3-Year Global Warranty
Every unit is covered for three years, with remote video support and spare parts stocked for dispatch worldwide.
Target Application Spectrum
The line is used where a high-viscosity paste must be developed to a controlled fineness and then filled without loss. Typical duties:
Printing Ink
Kneading, milling and filling of high-viscosity ink for printing applications.
Ink Manufacturing
Continuous batches of pigment-based ink where color strength depends on the roller milling step.
Plan Your Ink Production Line
Send the ink type, viscosity range, target batch size and packaging format. Our Wuxi engineers will recommend the roller size and the auxiliary equipment for the line.
