Top 3 problems that can bring your conveyor to a halt

1. Belt Mistracking

Problem: Belt mistracking occurs when your belt comes off track from its desired path. Belt mistracking is a serious problem that can lead to belt damage, equipment damage, and material spillage. There are many reasons that the belt mistracks such as inadequate belt tension, asymmetric loading, incorrect splicing, components out of square, and material build up on components and structures.

Solution: The best solution is to find the root cause of the mistracking to prevent future issues. Performing a conveyor audit can help identify all potential causes of the mistracking in order to pinpoint the right solution. If the conveyor is experiencing minor mistracking, self training idlers can be used to correct the belt track and ensure it continues to run straight in the future.


2. Material Carryback

Problem: Conveyor carryback occurs when small amounts of material adhere to the belt. This can lead to accumulation of material under the conveyor system or buildup on idler rolls and pulleys. Some materials, such as sticky clay and certain mineral ores are more prone to carryback than others. While the amount of carryback may seem negligible, over time it adds up to tonnes of material that must be taken care of a second time. Conveyor carryback also represents a safety and environmental hazard, adds to clean up costs, and generally prevents the conveyor system from performing at its best.

Solution: One simple solution is to install belt cleaners which are designed to prevent carryback. Their upfront capital cost is offset by their many benefits. Reducing fugitive material saves maintenance costs and creates a safer working environment. Additionally, a clean belt will reduce premature roller failure, increase belt life, and keep the system running optimally.


3. Belt Damage

Problem: Belt damage can be caused in several ways such as excessive impact forces, mistracking, poor application of sealing systems or cleaners, seized components, and insufficient pulley traction among others. With belts being the most expensive asset of the conveyor, it is critical to identify potential causes of belt issues and proactively work to avoid irreparable damage.

Solution: As there are many ways a belt can be damaged, there are also many different solutions. For example, installing impact idlers or cradles in the loading zone can diffuse the force of falling material which reduces wear and tear to the belt. Ensuring a proper sealing system is used prevents damage from entrapped material. Using the appropriate pulley lagging increases friction, preventing the belt from slipping, which would otherwise rapidly ruin the belt. These solutions can help minimize downtime and are often determined through a conveyor audit. Audits can catch minor belt damages and avoid catastrophic failures in the long run.
