Ceramic Substrate Cleaning Brush

Uniform Cleaning Across the Full Substrate Width

Working widths from 100 to 1,500 mm let the roller match your conveyor line exactly. Continuous nylon PA filament zones and PVA or PU sponge zones are built without side-to-side gaps, so the substrate receives the same mechanical cleaning action from edge to edge. Operators no longer need to hand-wipe or double-pass boards after an inline cleaning step.

Fine Particulate Removal Without Green-Body Damage

Filament diameters from 0.02 to 0.30 mm and soft open-cell sponge media apply controlled pressure across the contact zone. Engagement is set between 0.5 and 3 mm, keeping surface load below 2 N/cm² on fragile substrates. This removes loose dust and slurry while protecting thin green ceramic sheets, printed edges, and unfired multilayer stacks from cracking or corner chipping.

Absorbs Slurry and Liquid Instead of Pushing It Along

PVA sponge media wicks water-based slurry, oxide suspension, and cleaning solution into its pore structure as the roller rotates, then releases the liquid at the rinse or squeegee stage. The substrate leaves the roller zone drier, with less residual film and fewer re-deposited particles.

One Roller Can Handle Wet and Dry Touch Points

Media zones can be segmented on the same core, for example a nylon PA filament section for dry dust removal followed by a PVA sponge section for wet absorption. This lets a single brush assembly replace separate dry-brush and sponge-dry stations in space-limited ceramic lines.

Low Runout Keeps Contact Stable at Conveyor Speed

Roller assemblies are balanced and machined to a runout reference of 0.05 to 0.20 mm. That limits pressure pulses, vibration, and visible streaking on thin substrates, and helps keep the engagement depth constant instead of varying with each revolution.

Static-Safe Options for Sensitive Substrates

When requested, fill materials can be compounded to a surface resistance of 10³ to 10⁹ ohms and the shaft grounded through the machine interface. This reduces static attraction of fine ceramic dust and protects static-sensitive electronic substrates.

1. Match media to the residue and wet/dry condition

Use fine nylon PA filament for dry ceramic dust and light edge cleaning on fired substrates. Choose PVA sponge when the line is wet and slurry or oxide suspension must be absorbed while leaving a dry surface. Use PU sponge when mild cleaning chemicals or moderate abrasion are involved. Combined zones work when a dry dust removal stage and wet absorption stage happen close together.

2. Set contact to protect the substrate

Green and thin fired ceramic require the lowest engagement. Keep the contact depth at 0.5–1 mm and surface load below 2 N/cm². Thicker fired substrates can take 1–3 mm engagement. After setup, run one sacrificial panel and inspect edges and surface under magnification before committing the line.

3. Verify the mounting interface

Confirm keyway size, shaft diameter, bearing journal length, drive side, and end cap or flange detail against the existing machine. A mismatched shaft interface stops installation even if the cleaning media is correct.

4. Ask for low runout on high-speed or thin-substrate lines

For thin ceramic panels or line speeds that create vibrations, specify runout of 0.05–0.20 mm and dynamic balancing. Higher runout produces pressure pulsation, uneven streaks, and can break fragile edges.

5. Add ESD control when dust reattracts

If the process is static-sensitive, specify antistatic fill in the 10³–10⁹ ohm range and a grounded shaft path through the interface.

When a different tool is more suitable: If the task is to remove fired-on glaze, sintered deposits, or thick burrs, select a diamond, silicon carbide, or wire brush or a machining process instead. If the substrate is extremely thin and unsupported, consider air-knife, ultrasonic, or other contactless cleaning. If the residue is oily or organic, add a chemical cleaning stage; the brush removes particles but does not replace chemistry.
