06
Production lines by material viscosity
POLYC designs complete production lines matched to the material rheology. Low-viscosity coatings and inks use high-speed dispersers with horizontal bead mills. Medium-viscosity slurries such as wall plaster use double-shaft mixers. High-viscosity products such as adhesives, sealants and putty require planetary or butterfly double-shaft mixers with hydraulic presses.
- Low viscosity: coatings, inks - high-speed disperser + horizontal bead mill
- Medium viscosity: wall plaster, primers - double-shaft mixer with scraper
- High viscosity: silicone sealant, MS glue, putty - butterfly double-shaft mixer + press
- Custom: vacuum, explosion-proof, heating/cooling jacketed vessels

SF nano mill: typical application throughput
For nano circulation and multi-pass operation, the SF pin mill accepts grinding media from about 0.2 to 3 mm and reaches fineness in the nanometer range across a wide viscosity window. Reference throughput for typical nano ink pastes is as follows:
- Ceramic ink paste, D98 about 300 nm: reference rates around C 30 kg/h, K 30 kg/h, Y 25 kg/h, M 15 kg/h
- Inkjet / digital ink paste, D98 about 400 nm: SF20 reference about 300-350 kg per 8 h for C/K and 160-200 kg per 8 h for M/Y after 1:4 dilution
- Closed horizontal chamber with pin grinding system and centrifugal separation without screen
- Axle cooling keeps chamber temperature even, supporting narrow PSD and strong color strength
11
PUM grinding chamber design
The PUM chamber is designed for low-to-medium viscosity nano grinding. Product enters from the bottom, passes an outer and inner pin rotor, and the slurry recirculates internally before screenless centrifugal media separation.
- Bottom product inlet with an integrated pre-dispersing zone
- Outer plus inner pin rotor, working media about 0.1-1.5 mm
- Internal media recirculation with forced displacement of the bed
- Screenless centrifugal media separation
- High-efficiency cooling on rotor, outer stator, inner stator and bottom
12
Selecting the right grinding media size
Grinding bead diameter is selected from the maximum feed particle size. As a rule of thumb, media diameter should be 10-40 times the maximum feed particle size for coarse material, and 20-200 times for fine feeds. Too large a bead reduces fineness; too small a bead causes insufficient energy transfer and slow production.
| Feed Particle Size | Recommended Media Diameter | Typical Fineness After Milling |
|---|---|---|
| <= 30 um | 0.6 - 1.0 mm | <= 0.5 um |
| 30 - 100 um | 1.0 - 2.0 mm | 0.5 - 1.0 um |
| 100 - 300 um | 2.0 - 3.0 mm | 1.0 - 3.0 um |
| >= 300 um | 3.0 - 5.0 mm | 3.0 - 5.0 um |
- Feed <= 50 um: use 0.6-1.0 mm media for sub-micron results
- Feed 50-300 um: use 1.0-3.0 mm media for 1-3 um results
- Feed >= 300 um: use 3.0-5.0 mm media for 3-5 um results
13
Rotor and chamber material options
Wetted parts are selected based on contamination risk, abrasion, corrosion and product purity requirements. Standard alloy construction suits general coatings; ceramic or PU liners are used when zero metal contamination is required.
- Wear-resistant alloy: standard, cost-effective for general coatings and inks
- Tungsten carbide: hardened rotor tips for high-abrasion pigments
- Zirconia ceramic (ZrO2): zero metal contamination for battery slurries and electronic pastes
- Polyurethane (PU): anti-corrosion and anti-wear for aggressive slurries
- SiC chamber: silicon carbide lining for ultra-fine and contamination-free grinding
14
High-viscosity mixing solutions
For silicone sealants, adhesives, putties and offset inks, POLYC supplies butterfly double-shaft mixers, three-shaft mixers and planetary mixers with hydraulic press-out systems. Vessels can be forklift-movable with cooling jackets and vacuum covers.
- Butterfly double-shaft mixer with press: for silicone sealant and MS glue
- Three-shaft mixer: popular for adhesive and sealant production lines
- Planetary mixer: for battery slurries and high-viscosity pastes
- Vacuum cover, temperature probe and inflatable seal options available

Milestones
POLYC MACHINE was founded in 2006 in Shanghai as a machining and equipment fabrication business. That same year the Jiangyin manufacturing base and first in-house product line were established, moving the company from contract machining to complete equipment supply for coating and ink producers. The Shanghai company was formed in 2021 to coordinate international projects and exports, and equipment now runs in more than 80 countries.

- Today - more than 8,000 systems delivered to over 80 countries
Manufacturing capability in practice
Fabrication
Vessels, frames, platforms and pipework are fabricated around the selected materials, pressure conditions, cleaning needs and plant layout.
Assembly & testing
Mechanical assembly, electrical integration and agreed functional checks are completed before shipment. Test scope is documented for each project.
Core technology families
Grinding equipment
Basket, disc and pin-type bead mills cover flexible batch processing, productive micron grinding and contamination-controlled nano applications.
Dispersion equipment
High-speed, vacuum and inline dispersers support powder wetting, de-agglomeration and preparation of stable feed for downstream milling.
Mixing equipment
Planetary, double-shaft, triple-shaft and ribbon mixers process high-viscosity pastes, slurries, sealants and dry powders.
Quality documentation and verified conformity
POLYC MACHINE reviews product-contact materials, component configuration, dimensional checks and functional testing according to the agreed project scope. Documentation can include approved drawings, material information, inspection records, manuals and a factory acceptance checklist.
Verified model-specific documents include Basket Mill CE Machinery Directive Attestation M.2023.206.C.90346 and Bead Mill CE Machinery Directive Attestation M.2023.206.C.90347, both valid until 13 September 2028. Applicability must be confirmed for the quoted model. No general ISO 9001 or general ATEX certification is claimed on this page.
Export coordination and service capability
The Shanghai team coordinates international enquiries, technical review, documentation and shipment support for customers worldwide. Responses to web enquiries are targeted within 24 hours. Time-zone differences, project complexity and required engineering review can affect detailed proposal timing.
Support can include installation guidance, commissioning coordination, operator training and spare-parts planning. Site work, travel scope and local compliance responsibilities are agreed in the contract before dispatch.
Research and engineering workflow
Engineering begins with material and process data rather than a model number. The team reviews solids, viscosity, particle size, temperature, corrosion, contamination, cleaning, capacity and plant utilities before preparing a process route and layout.
The project can progress through technical clarification, proposal drawings, configuration approval, fabrication, factory acceptance testing and shipment. Site acceptance criteria should use the same measurement methods agreed during the design and trial stages.
