Ceramic wear liner

Alumina tiles bonded into a chute or hopper; extremely hard and long-lasting in abrasive flow.

Al₂O₃ ≥ 92 %

Alumina ceramic tile

92–95 % alumina tile, typically 10–25 mm thick, used as the working face of a wear liner.

10–25 mm

Basalt cast liner

Cast basalt plate with very high abrasion resistance; economical for straight chute walls.

Chromium carbide overlay

Hardfaced steel plate with a chromium-carbide layer for severe impact plus abrasion.

HRC 55–60

Wear plate (Hardox-type)

Quenched and tempered abrasion-resistant steel plate, typically 400–500 HB.

400–500 HB

UHMWPE liner

Ultra-high-molecular-weight polyethylene sheet with a very low friction coefficient; stops sticky build-up.

μ ≈ 0.1

HDPE liner

High-density polyethylene liner; cheaper than UHMWPE, good for mildly sticky material.

Rubber wear liner

Rubber sheet bonded to impact zones; absorbs energy and resists gouging.

Rock box (dead box)

Recess in a chute that traps a permanent layer of material so the flow hits material, not steel.

Skirt rubber

Rubber curtain along the skirt board that contains material and dust at the loading point.

Dust seal

Flexible strip closing the gap between chute and belt to stop dust escape.

Dry fog system

Ultrasonic water-fog nozzles that agglomerate dust particles without wetting the material.

droplet < 10 µm

Dust extraction hood

Enclosure over the transfer point connected to an extraction fan and filter.

Bag filter (dust collector)

Fabric-filter dust collector that captures the extracted air-borne dust.

EN 60335

Cyclone dust separator

Centrifugal pre-separator that drops the coarse fraction before the bag filter.

Dust suppression cover

Fabric or steel cover over a conveyor run to keep wind-blown dust inside.

Conveyor cover (weather cover)

Arched galvanised or plastic cover that keeps rain and snow off the belt.

Belt wash station

Water spray plus scraper and drier that cleans the return belt after sticky cargo.

Air knife (belt drier)

High-velocity air jet that blows carry-back moisture off the belt after washing.

Primary belt cleaner

Blade pressed against the head pulley that removes the bulk of the carry-back.

Secondary belt cleaner

Second blade behind the head pulley that finishes the cleaning job.

Tungsten carbide cleaner blade

Hard-metal tipped scraper blade for aggressive, long-life cleaning.

Polyurethane cleaner blade

Softer blade for mechanical splices and delicate belt covers.

H-type cleaner blade

Segmented blade shape that maintains contact across the whole belt width.

V-plough (belt plough)

V-shaped plough on the carrying belt that diverts material sideways before the pulley.

Rotary brush cleaner

Motor-driven brush that sweeps fines off the belt; gentle on splices.

Chute liner

Replaceable plate lining the inside of a transfer chute at the wear zone.

Hopper liner

Liner in a bin or hopper that promotes flow and protects the shell.

Curved chute

Chute shaped to follow the material trajectory so lumps arrive on the belt in the direction of travel.

Spoon (loading spoon)

Curved guide that lays the material gently onto the belt at the loading point.

Flow guide (deflector)

Internal plate that steers the stream and centralises the load on the belt.

Ceramic pulley lagging

Ceramic-bead rubber lagging that grips the belt at high torque without polishing.

μ ≈ 0.4–0.5

Diamond rubber lagging

Grooved rubber lagging that lets water escape and improves grip in the wet.

μ ≈ 0.35

Plain rubber lagging

Smooth rubber lagging for tail and snub pulleys where grip is not critical.

μ ≈ 0.25

Wear-resistant chute lip

Replaceable hard lip where the material leaves the chute and lands on the belt.

Wear liner (ceramic)

Alumina tile lining for the highest-wear zones of chutes and hoppers; far longer life than steel but brittle under impact.

Al₂O₃ 92 %ISO 14704

Wear liner (UHMWPE)

Very low-friction polymer lining that stops wet, sticky material from building up in chutes.

μ ≈ 0.1

Wear plate

Replaceable quenched or hard-faced steel plate bolted or welded over the working surface of a chute.

HB 400…500ISO 6507

Impact bar (slider bar)

Urethane or rubber-covered bar under the loading point that absorbs lump impact instead of the belt carcass.

CEMA 575

Dust suppression system

Water spray or fog system at transfer points that binds airborne dust before it escapes the chute.

ISO 21873

Air cannon

Compressed-air blast device that clears arches and rat-holes in bins, silos and chutes.

0.4…0.8 MPaISO 21873
