Three major problems that cause conveyor downtime

28th July 2020

If the conveyor is improperly maintained, the belt may quickly wear out and component failures may cause downtime and repairs. This will have a corresponding negative impact on productivity and profits. Therefore, we must improve our understanding of the common problems of conveyors, and learn to solve and prevent conveyor problems. Let's learn about the three major problems of conveyor shutdown and the reasons for the solution with the editor of the conveyor belt:


1. Common problems of conveyors:


Material transportation in mines accounts for a large proportion of total mining costs. Therefore, the conveying system has become a common solution to improve operation efficiency. The challenge is that conveyors usually operate under extremely harsh conditions, such as dirty environments, excessively high or low temperatures, and high humidity. If not properly maintained, the conveyor may experience rapid belt wear and component failure, resulting in downtime and repairs. This will have a corresponding negative impact on productivity and profits.


2. The three main problems of common conveyor shutdown and their solutions:


1. Belt deviation


Problem: When the belt deviates from its required path, belt deviation will occur. This is a serious problem that can cause belt damage, equipment failure and material spillage. There are many reasons for belt deviation, such as insufficient belt tension, eccentric load, incorrect splicing, component deviation, material accumulation on components and components, etc.


Solution: A better solution is to find the root cause of belt deviation to prevent the same problem in the future. Carrying out a belt inspection can help identify potential problems causing misalignment in order to develop a suitable solution. If the belt has a slight deviation, you can use the self-aligning idler to correct the trajectory of the belt and ensure that it will always run straight in the future.


2. Material return


Problem: When a small amount of material adheres to the belt, the conveyor will be transported back. This can cause materials to accumulate under the conveyor belt, or on rollers and drums. Certain materials, such as cohesive soil and certain ores, stick to the belt more easily than others. Although the amount of return transportation is very small, but after a long time, there will be tons of materials accumulated, and it has to be cleaned twice. The return of materials can also cause safety and environmental hazards, increase cleaning costs, and is generally not conducive to the optimal operation of the conveyor system.


Solution: A simple solution is to install a belt cleaner designed to prevent back shipment. The many benefits brought by the belt cleaner are enough to offset its initial investment cost. Reduce material spills, save maintenance costs, and create a safer working environment. In addition, a clean belt can also prevent premature damage to the idler roller, extend the life of the belt, and keep the system in a better operating condition.


3. The belt is damaged


Problem: There are several reasons for belt damage, such as excessive impact, deviation, improper use of the sealing system or belt cleaner, component jamming, and insufficient drum traction. The belt is a more expensive part of the conveyor, so the potential cause of the belt problem must be found and measures must be taken actively to avoid irreversible damage.


Solution: There are many reasons for belt damage, so there are many different solutions. For example, installing buffer rollers or brackets in the feeding area can disperse the impact of falling materials, thereby reducing wear and tear on the belt. Using a proper sealing system can prevent the belt from being damaged by stuck materials. The use of appropriate roller coating materials can increase friction and prevent belt slipping without being damaged quickly. These solutions all help to reduce maintenance downtime to a large extent, which can usually be determined through a belt inspection. Belt inspection can catch minor belt damage and avoid serious failures in the future.
