Conveyor systems are the backbone of many Australian mining, quarrying, and bulk material-handling operations. When they’re running efficiently, they keep production moving. But when maintenance is overlooked, seemingly minor issues can quickly escalate into significant safety risks for workers and costly unplanned downtime.
Many of the most common conveyor problems share one thing in common: they are preventable. By identifying hazards early and implementing proactive maintenance practices, sites can create safer working environments while extending the life of critical equipment.
Hazard one: Dust and material spillage
Dust generation is an unavoidable part of handling aggregate and other bulk materials, but excessive dust escaping from conveyors should never be accepted as normal.
Poorly sealed transfer points, worn skirting, damaged belts or ineffective load zones can allow dust and fine material to escape, creating airborne hazards and increasing housekeeping requirements. In Australia, exposure to respirable crystalline silica and other airborne contaminants remains a major health concern across mining and quarrying operations.
Material spillage also creates slip and trip hazards around conveyors and often requires workers to perform manual clean-up activities in potentially hazardous areas.
Regular inspections, well-maintained skirting systems and effective load point support can significantly reduce dust emissions and minimise unnecessary worker exposure.
Hazard two: Carryback
Carryback occurs when material remains adhered to the conveyor belt after discharge, eventually falling beneath the return side of the system.
While often viewed as an operational nuisance, excessive carryback can create substantial safety concerns. Accumulated material around walkways and structures increases slip hazards, while falling material from elevated conveyors may expose personnel below to injury.
Carryback also accelerates wear on conveyor components, potentially leading to belt damage, premature failures and unplanned maintenance activities that place workers in higher-risk situations.
Installing and maintaining effective belt cleaning systems help minimise carryback, reduce manual cleaning requirements and support safer access around conveyor infrastructure.
Hazard three: Belt mistracking
A mistracking conveyor belt is more than an equipment issue; it can become a serious safety hazard if left unresolved.
When belts drift off-centre, they place abnormal stress on structures, idlers and other conveyor components. Continued friction may damage the belt or surrounding equipment and increase the likelihood of unexpected failures.
Mistracking can also contribute to material spillage, creating hazards beneath and alongside the conveyor. In severe cases, damaged belts or splices may require emergency repairs that expose maintenance personnel to additional risks.
Routine inspections and properly maintained tracking equipment can identify alignment issues before they develop into larger problems.
Prevention is the best safety strategy
While no operation can eliminate every maintenance challenge, a proactive approach dramatically reduces the likelihood of incidents.
Routine conveyor inspections, condition monitoring, effective belt cleaning, dust management systems and ongoing workforce training all contribute to safer operations. Early intervention not only protects equipment but also reduces the need for reactive maintenance, limiting worker exposure to hazardous conditions.
For Australian operations, conveyor safety should be viewed as an ongoing process rather than a one-time fix. Investing in preventive maintenance and regularly reviewing conveyor performance can help sites reduce risk, improve reliability and create a safer workplace for everyone working around bulk material handling systems.
Every conveyor system is different, but proactive maintenance remains one of the most effective ways to reduce risk and improve reliability. Flexco works with operations across Australia to help identify potential hazards and implement practical solutions that support safer, more efficient conveyor performance.
