Choosing the Right Dynamic Disc Bead Mill
How to Choose1
Match throughput and chamber size
Pick a chamber from the 5 to 150 L range so the mill delivers your target 50 to 1,500 L/h continuous output, with smaller 5 to 30 L chambers for pilot and specialty runs.
2
Set fineness and media
Plan for the 1 to 15 micron window with 0.3 to 2.0 mm zirconia media; if you need sub-micron or nano sizes, pair the line with a pin-type nano bead mill instead.
3
Confirm contact material and cooling
Specify stainless steel, ceramic-lined or hardened alloy for the contact parts, and keep the jacketed chamber with temperature interlock for heat-sensitive agrochemical and ink formulations.

Description
How it works
The POLYC dynamic disc type horizontal bead mill is a continuous wet grinding mill built for high-volume fine grinding of pigments, paints, inks, agrochemical SC formulations, ceramics and battery slurries. Material flows through a sealed horizontal grinding chamber where a dynamically agitated disc rotor drives 0.3 to 2.0 mm zirconia beads to reduce particle size, then discharges continuously without batch transfer, which makes it suited to steady high-volume production rather than frequent small-batch changeover. The mill covers a chamber volume of 5 to 150 L with motor power from 11 to 75 kW and throughput of 50 to 1,500 L/h, delivering a fineness range of 1 to 15 micron. The grinding chamber is jacketed for cooling water and fitted with a temperature interlock that stops the mill if material temperature exceeds the preset limit, protecting heat-sensitive formulations during continuous high-load grinding, and contact parts are offered in stainless steel, ceramic-lined or hardened alloy to match abrasiveness and corrosion needs. Operation is paired with a high-speed disperser for pre-dispersion in most paint, ink and agrochemical lines, and the mill is built for straightforward maintenance with accessible seals, screen and disc rotor. POLYC specifies chamber size, contact material, drive power and cooling per application, and provides layout, installation guidance and spare-part support for continuous-production lines.

Frequently Asked Questions
What is the POLYC dynamic disc type horizontal bead mill and what does it do?
The POLYC dynamic disc type horizontal bead mill is a continuous wet grinding mill built for high-volume fine grinding of pigments, paints, inks, agrochemical SC formulations, ceramics and battery slurries. Material flows through a sealed horizontal grinding chamber where a dynamically agitated disc rotor drives 0.3 to 2.0 mm zirconia beads to reduce particle size, then discharges continuously without batch transfer.
What fineness can the dynamic disc bead mill achieve?
The mill delivers a fineness range of 1 to 15 micron using 0.3 to 2.0 mm high-purity zirconia media. For most pigment, coating and agrochemical applications this covers the standard 1 to 15 micron window; where sub-micron or nano sizes are required, a pin-type nano bead mill is the better choice.
What grinding media and contact materials are used?
Grinding uses 0.3 to 2.0 mm zirconia beads, and contact parts are available in stainless steel, ceramic-lined or hardened alloy depending on abrasiveness and corrosion needs. The ceramic-lined and hardened-alloy options protect the chamber when grinding abrasive pigments or fillers.
How is temperature controlled during continuous grinding?
The grinding chamber is jacketed for cooling water and fitted with a temperature interlock. The interlock stops the mill if material temperature exceeds the preset limit, protecting heat-sensitive formulations such as agrochemical SC and solvent-based inks during continuous high-load grinding.
What throughput and chamber sizes are available?
Chamber volume spans 5 to 150 L across the range, with motor power from 11 to 75 kW and throughput of 50 to 1,500 L/h. Smaller 5 to 30 L chambers suit pilot and specialty runs, while the 150 L chamber serves high-volume continuous lines.
How does a dynamic disc mill differ from a basket mill?
A basket mill works batch-wise in a single vessel and suits frequent colour changes and multi-shade production, while the dynamic disc horizontal bead mill runs continuously through a sealed chamber for higher hourly throughput and finer, more uniform particle size. Choose the bead mill for steady high-volume output and the basket mill for flexible small-to-medium batches.
Do I need a disperser before the bead mill?
Usually yes. A high-speed disperser first wets and deagglomerates the powder, then the bead mill does final fine grinding. This two-step process gives better results and faster milling than feeding dry powder directly into the bead mill, and it is the standard configuration for paint, ink and agrochemical lines.
Is the dynamic disc bead mill customizable and how is it maintained?
Yes. Chamber size, contact material (stainless, ceramic-lined or hardened alloy), drive power and cooling are specified per application, and the mill is built for straightforward maintenance with accessible seals, screen and disc rotor. POLYC provides layout, installation guidance and spare-part support for continuous-production lines.
