Conveyor Solutions by Industry
Conveyor Solutions for Aggregates & Quarries
Rock, sand and gravel are the most abrasive bulk solids on a belt. We supply impact idlers, ceramic-lined pulleys, polyurethane cleaners and self-training idlers engineered for crusher-discharge shock, extreme wear and belt protection.

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.
Extreme Abrasion
Crushed stone and sharp sand wear shells, pulleys and scrapers faster than almost any other bulk solid.
Crusher-Discharge Impact
Material dropping from crushers and screens hits the belt with massive localized force.
Belt Tearing & Damage
Sharp lumps and trapped rock slice and gouge belts, causing costly splice failures.
Spillage & Dust
Misaligned, poorly cleaned belts spill product and create dusty, unsafe plants.
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.
Absorb the Shock
Impact Idler
Cushioned carrying idler that absorbs lump impact directly at the transfer point.
Buffer Bed
Energy-absorbing bar bed that protects the belt from tears and eliminates idler breakage.
Ceramic & Polyurethane
Ceramic-lined Pulley
Embedded ceramic tiles for superior grip and wear life on abrasive belts.
Polyurethane Cleaner
PU blade that outlasts rubber against sharp, abrasive carryback.
Stay Aligned, Stay Clean
Plastic Dust Seal
Multi-stage labyrinth + lip seal that blocks slurry and dust from the bearing cavity.
Conical Training Idler Set
Conical set that self-centres the belt and stops spillage.
Full Belt Support
Troughing Idler
Standard carrying set for main belts; matched to belt width and trough angle.
Buffer Idler Set
Cushioned impact set for secondary load zones and bins.

Common Questions
Sector Conveyor FAQ
How long do ceramic pulleys last on abrasive rock?
Ceramic-lined pulleys significantly outwear plain or rubber-lagged pulleys on crushed stone, holding grip and profile far longer in high-slip, abrasive duty.
Do you have impact idlers for crusher discharge?
Yes. Our impact idlers and buffer beds are sized to your drop height and lump size to absorb the localized shock that otherwise tears belts.
Can training idlers stop spillage?
Conical self-training sets actively re-centre the belt, eliminating the wander that causes spillage and edge wear.
What resists sharp-aggregate abrasion best?
Ceramic-lined pulleys for grip and wear, paired with polyurethane cleaners and sealed housings — a combination built for crushed-stone service.
