An industrial rotary brush roller designed to keep aggregate screening decks open by lifting near-size particles, fines, and wet blinding material out of mesh and plate apertures. It mounts under or alongside wire mesh, perforated plate, and wedge wire decks to reduce manual deck cleaning and maintain screen throughput.
What can this brush do for you?
Lifts Near-Size and Fine Material Out of the Apertures
Filament tips are set to enter the screen openings with 2-10 mm of radial engagement. As the roller rotates, each pass pushes wedged particles back through the deck before they compact into a blind. The screen holds more of its open area through wet, high-fines runs.
Wears the Filaments, Not the Screen Media
Only 5-25% of the free filament length is compressed against the deck, and polypropylene or nylon tips flex with the screen vibration instead of loading the wires. The filament layer acts as the sacrificial wear surface, so mesh and perforated plate last longer than they would under metal scrapers or manual hammering.
Keeps Working in Wet and Clay-Bound Feed
Polypropylene and nylon monofilaments resist moisture, rot, and most plant chemicals. Their smooth surface lets wet clay, slurry fines, and fibrous material release from the tips instead of wrapping around the core. Brushes stay balanced and effective in wash plants and on damp stockpiles.
Cleans Edge-to-Edge Across the Deck
The brush is built to the specified screen working width and installed with 5-15 mm of overlap on each side. That covers the side plate zones where fines pack and moisture collects, so blinding does not start at the frame and spread inward.
Drops Into Your Existing Screen Setup
Choose a fixed rail for straight-line wiping, an idler roller that follows screen motion, or a driven shaft for controlled rotation. Replacement brushes can match the existing bearing centers and drive hardware, reducing engineering and installation time.
What is an Aggregate Screen Cleaning Brush?
An Aggregate Screen Cleaning Brush is a cylindrical brush roller built for continuous anti-blinding duty on aggregate screening equipment. A steel or alloy core carries radial polypropylene or nylon monofilaments along its working face. The completed roller is mounted beneath or alongside a screen deck so the filament tips can contact the back of the mesh or plate and enter the apertures with a controlled, adjustable engagement.
During operation, the brush rotates against or across the deck while the screen continues to vibrate. The tips interrupt particle bridges, lift fines and near-size stone back into the material flow, and wipe wet residue from the underside of the deck. Free trim length, filament diameter, row pattern, and contact setting are selected for the specific aperture size, deck motion, and feed conditions rather than copied from a general-purpose brush.
This is a process brush, not a hand tool or a wire scratch brush. It is intended for routine clearing of blinding and pegging in screening circuits. It does not replace screen inspection, spray bars on wash screens, or manual removal of oversized rock that has been forced into a large aperture.

Free trim is the filament length measured from the core face, and installed contact is the portion of that trim compressed against the deck in the operating position. Both are checked at the final position before the drive is connected.
Where does this brush work best?
- Vibrating screen decks in quarries and aggregate plants running sand, crushed stone, limestone, and recycled concrete.
- Fine and medium-aperture woven wire and self-cleaning mesh where near-size particles wedge into openings.
- Perforated plate and punch plate decks that blind on the underside from damp fines and compacted dust.
- Wedge wire and slotted screens used in dewatering, washing, and fines recovery circuits.
- Feeds containing moist, clay-bearing, or fibrous material that packs into apertures within a shift.
- Rotary trommel screens and screen baskets where a mounted brush rail or roller wipes the drum surface.
The brush delivers its highest value where blinding develops quickly and repeatedly. On screens that stay open for weeks, it adds cost without a matching throughput benefit.
How do I choose the right one?
Start with the screen deck
Measure the working width between side plates and record the aperture size, shape, and open area. Also record the deck type and the screen motion: linear, circular, or elliptical. These numbers set the brush working length, outside diameter, filament spacing, and row pattern.
For fine and medium apertures, smaller filament diameters reach into the openings without forcing them open. For coarser apertures and heavier near-size stone, larger filaments provide the stiffness needed to lift the particle.
Choose filament material by moisture and wear
Polypropylene absorbs almost no water, releases wet clay and slurry fines well, and is a good first choice for wet screening and wash plants. Nylon offers higher toughness and better abrasion resistance in dry, sharp aggregate but absorbs some moisture and will lose a small amount of stiffness when soaked. Specify the screened material, moisture level, and whether the deck runs wet or dry so the filament grade fits the process.
Set contact and engagement before increasing force
Position the brush so the tips engage 2-10 mm into the apertures, with only 5-25% of the free trim compressed against the deck. Less engagement leaves openings untreated; more engagement shortens filament life, increases drive load, and can distort fine wire. Start at the low end and increase only until the blinding clears.
Match the mounting to the screen frame
A driven shaft gives consistent rotation and positive aperture clearing on heavily loaded decks. An idler roller is simpler and works when screen vibration provides enough relative movement. A fixed rail brush is the right form where a straight wipe across the full width is sufficient and no drive package is available. Confirm bearing spacing, shaft centers, and available clearance under or beside the deck before ordering.
When this brush is not the best tool
Use a different solution when the deck openings are very large and the material is dry and free-flowing; the brush adds cost without a blinding problem to solve. For extremely hard, abrasive aggregate, plain PP or PA filaments will wear faster than aggressive low-wear materials or alternative deck-cleaning systems, so compare total cost per ton. For hard-caked scale, dried cementitious fines, or large wedged rock, a brush alone may not generate enough force. Combine it with spray bars, mechanical knockers, or manual clearing where the process requires.
Can I customize this brush?
Yes. Aggregate screen cleaning brushes are quoted per screen rather than selected from a fixed catalog, so the following can be adjusted to the deck and operating conditions:
- Brush geometry: outside diameter, working length, free trim, filament diameter, row pattern, fill density, and end extensions.
- Filament options: polypropylene or nylon, plain or specialty grades, with color used for visual wear indication where required.
- Core and shaft: solid or tube construction, keyed ends, flanges, bearing journals, and sprocket or sheave seats.
- Mounting hardware: brackets, rails, pillow block positions, and drive couplings matched to the screen frame.
- Packaging and handling: bulk pallet loading, cradles for long rollers, moisture-barrier wrapping for nylon, and marking or labeling for plant identification.
To define the custom configuration, provide the screen working width, aperture dimensions and pattern, deck type and motion, wet or dry conditions, available mounting space, and whether the brush will be driven or idler-mounted. If the project requires material documentation, inspection reports, or third-party testing, we can arrange that support during the customization process.
What speed and pressure suit an aggregate screen cleaning brush, and how is that checked?
How can I confirm the brush is engaging the screen evenly before startup?
Place a strip of chalk, layout dye, or carbon paper on a clean section of the screen under the brush. Rotate the brush by hand through one full revolution at the intended contact setting and inspect the mark. The contact band should run the full working width and reach into the apertures without swallowing the tips. Adjust the mounting or end brackets until the mark is even before connecting the drive.
Should the brush be mounted below or above the screen deck?
For aperture blinding and pegging, mount the brush below the deck so the tips can push lodged particles back out of the openings. An above-deck brush only wipes material lying on the surface, so it helps with surface buildup but does not clear the apertures. Some plants use both positions when the feed causes both types of fouling.
What happens if the tips are set too deep into the screen openings?
Excessive engagement bends the tips, accelerates filament wear, increases drive current, and can distort fine wire mesh. If the brush is buried more than about 10 mm into the openings or more than about 25% of the free trim is compressed, reset the roller and recheck the contact mark.
Will this brush clear a large rock wedged in the aperture?
Usually not. The filaments clear near-size particles, fines, and wet blinding material. A rock that is larger than the opening and has been forced in by impact is a pegging problem that needs manual removal, a different screen media design, or a screen media change. The brush prevents the smaller material from building up around such a rock; it does not replace the pry bar.
Does the brush become the new maintenance item instead of the screen?
Yes, and that is the point. The filament layer is designed to be sacrificial. Scheduled filament inspection and replacement are simpler, safer, and less expensive than replacing torn mesh or perforated plate. Track filament wear by measuring the remaining free trim and engagement at each monthly inspection, and replace the brush when the contact setting can no longer be held without over-compression.
Can one brush work for both wet and dry screening?
It depends on sizing and material selection. Polypropylene handles wet, clay-bearing feed with less buildup, while nylon offers more toughness in dry sharp aggregate. If a plant switches seasonally between wet and dry feed, we can build a brush with a compromise filament grade or supply two brush sets configured for each operating mode rather than forcing one roller to do both jobs.
