Conveyor chains are used to drive different types of conveyor units and use different types of power transmission. If you want to get the most out of your equipment, make sure you maintain them. This is even more important if they are installed in the mining and construction industry. Given below are a few tips that can help you ensure your conveyor chains will continue to work properly.
1. Follow the Maintenance Schedule
First of all, you may want to inspect and service them to ensure proper alignment, lubrication and tension. If inspected on a regular basis, they can last up to 15,000 hours. It’s better if you schedule filter and oil changes every 3 months. On the other hand, the cleaning of bigger parts, such as shafts, machine lubrication and replacement of damaged or worn sprockets and sideplats should be done on an annual basis.
Following the maintenance schedule is paramount, especially if you have installed the conveyor chains in the construction and mining industry.
2. Lubricate Wisely
For smooth operation, conveyor drives and chains should be free of moisture and dust. Most of these systems require petroleum-based oil. It’s not a good idea to opt for heavy greases and heavy oils. The reason is that they are overly stiff and can’t lubricate the system properly. Given below are some common ways of lubricating the conveyor chains. Some of them are listed below:
- Stream lubrication
- Disk lubrication
- Drip lubrication
- Manual lubrication
Based on the power and chain speed, the right method can be used. For reducing wear and tear and enjoying all the benefits, it’s important that you lubricate the system properly.
3. Get Heat-Treated Parts
Heat treatment can be used to improve the mechanical components. Therefore, manufacturers control the treatment methods for best results. In other words, to reduce wear and tear, it’s important to perform proper heat treatment.
Case hardness and depth are the two primary parts of component heat transfer. This plays a great role as far as resistance and durability is concerned. If the depth is too much, the parts may break while working due to brittleness.
4. Make sure there is Proper Alignment and Tension
Make sure you check the slack span and chain tension, and perform the required maintenance. If you need to reduce the tension, you can eliminate two pitches and then connect the chain again. However, you may need to replace the entire chain if the wear and tear goes beyond the functional limits.
Also, you may not want to connect new chains to the worn one as it can damage the drive. Misaligned sprockets can also cause the link plates of the roller chain to get a lot of wear and tear.
5. Check the Primary Parts
Typically, conveyor chains have two main parts that go through wear and tear: sprockets and chain. Chain stretching happens due to this very reason and results in the complete replacement of the sprockets and chain.
Therefore, you should inspect conveyor chains for any broken parts, deformation and cracks.
In short, these are the tips you can follow to maintain your roller chains.
