Choosing the right bulk material handling system has a direct impact on the performance of any industrial plant. However, just as important as the equipment itself is choosing the right drag chain conveyor supplier and implementing smart maintenance to extend its service life.
In this article, we outline what to consider when looking for a specialist supplier and how to implement efficient chain conveyor maintenance to maximise availability and operational safety.
Why choose custom drag chain conveyors?
Standard drag chain conveyors work in simple situations, but when the material is abrasive, hot or difficult to handle, such as in the chemical sector, the only way to guarantee performance is with a customised design. A bespoke chain conveyor takes into account:
- Material characteristics (grain size, moisture content, abrasion).
- Required flow rate and operating conditions.
- Geometry of the route, with inclines, changes in height or complex layouts.
- Physical space available in the plant.
In short, a standard solution may work… but it rarely does so with the efficiency, durability and low maintenance that today’s industry demands.
How to identify a good drag chain conveyor supplier?
When a company is looking for drag chain conveyor suppliers, it is important to consider the following points:
- Comprehensive technical analysis: A reputable supplier will assess the nature of the material, the slope, the flow rate, the distances and the geometry of the route. They will not just offer equipment, but a comprehensive solution.
- Flexible and 100% customised designs: Drag chain conveyors allow for Z or L configurations, multiple discharge points and modular structures. This design freedom makes all the difference in installations with space constraints.
- Robust construction: Heavy-duty chains, replaceable wear guides, enclosed boxes and removable inspection covers. All of this increases the durability of the system and greatly facilitates maintenance.
- Guaranteed after-sales service and spare parts: A good supplier does not just deliver the equipment. They offer technical documentation, long-term availability of spare parts and responsive technical support.
When you work with a supplier who specialises in customised drag chain conveyors, the difference is noticeable throughout the plant. Not only does the equipment work well, but availability improves, unexpected downtime is virtually eliminated, and maintenance is no longer a race against time. In addition, costs stabilise over time because wear and tear is reduced and each component is designed to last.
Efficient maintenance tips for drag chain conveyors
Maintenance is the other key factor in ensuring that a chain conveyor operates smoothly. It all starts with regular inspections and, above all, learning to read the conveyor’s behaviour. A simple visual inspection of the chain can reveal slack, small breaks or areas of abnormal wear that should be addressed before they get worse. The same applies to tensioning: a well-tensioned chain smoothes movement, prevents load peaks and significantly reduces the risk of premature failure. And, of course, keeping the guides and sliding elements clean helps to ensure smooth traction, without vibrations or unnecessary strain.
Then there is the care of critical components, which makes a difference in the long term. Proper lubrication helps minimise friction. It is also advisable to plan for the replacement of chain blocks or segments when wear is already visible, because replacing them in time is always more economical than stopping the line due to an unexpected breakage.
Operating conditions also speak volumes. Particularly abrasive materials or high temperatures require more frequent checks. Humid or dusty environments accelerate corrosion and can compromise the integrity of the chain if not monitored. On the other hand, a closed design helps reduce dust emissions and makes daily maintenance much easier.
Finally, keeping track of spare parts and technical documentation makes maintenance a much quicker and safer task. Having critical parts in stock allows you to react quickly to any incident. Recording operating hours, anomalies or interventions helps to detect wear patterns and anticipate problems, rather than reacting too late. And when all this information is well organised, the conveyor ceases to be a source of uncertainty and becomes predictable and easy to maintain.
The value of a good supplier and intelligent maintenance
The combination of a supplier specialising in customised drag chain conveyors and a well-structured maintenance strategy is the key to achieving an efficient, safe plant with a long service life for your transport system.
When the material requires robustness, precision and reliability, the drag chain conveyor is the most stable solution. And when backed by an experienced supplier and proactive maintenance, it becomes a very profitable investment.
