Conveyor Solutions by Industry
Conveyor Solutions for Coal Handling
Coal is abrasive, dusty and potentially explosive. We supply anti-static FRAS idlers, impact buffer beds, primary scrapers, sealed housings and conveyor rain covers engineered for coal galleries, surface yards and reclaim tunnels — backed by MA mine-safety certification.

Why This Industry Is Different
Four Sector-Specific Conveyor Challenges
Every bulk solid wears conveyors differently. Below are the duty conditions we engineer against for this sector.
Coal-Dust Explosion Risk
Accumulated coal fines and static discharge are a serious ignition hazard in galleries and tunnels.
Abrasion & Belt Wear
Sharp, hard coal wears shells, scrapers and pulleys faster than most bulk solids.
Outdoor Yard Weather
Rain and sun degrade belts and rollers in open storage and reclaim conveyors.
Continuous Fuel Supply
A stopped fuel line can trip generation — reliability is non-negotiable.
Matched to Your Duty
Products for This Sector
Each component below is selected for the duty described above. Click through for specifications, materials and lead times.
FRAS & Troughing Idlers
Polyurethane Friction Idler
Anti-static, low rolling-resistance roller for potentially explosive underground drives and galleries.
Troughing Idler
Standard carrying set for main belts; matched to belt width and trough angle.
Buffer & Clean
Buffer Bed
Energy-absorbing bar bed that protects the belt from tears and eliminates idler breakage.
Primary Scraper Cleaner
Removes bulk coal carryback at the head pulley.
Covers & Seals
Conveyor Rain Cover
Galvanised cover that shields outdoor yard and reclaim belts from rain.
Plastic Dust Seal
Multi-stage labyrinth + lip seal that blocks slurry and dust from the bearing cavity.
Pulleys & Emergency Stop
Drive Pulley
Rubber-lagged, dynamically balanced pulley for high-torque conveyors.
Pull Cord Switch
Emergency-stop along the belt — mandatory for personnel safety on mine lines.

Common Questions
Sector Conveyor FAQ
Are your idlers anti-static for coal dust?
Yes. Our polyurethane friction idlers are anti-static for coal-handling galleries and reclaim tunnels, supported by MA certification at company level.
Do you supply rain covers for outdoor yards?
Yes. Galvanised conveyor rain covers shield open-yard and reclaim belts from rain and UV, extending belt and roller life.
How do you control coal carryback and dust?
Primary scrapers at the head pulley plus sealed housings keep coal fines off pulleys and out of bearings, reducing housekeeping and emissions.
Can you support base-load reliability?
Components are built for continuous duty with balanced pulleys and sealed bearings; we supply spare kits to keep fuel lines running.
