Tackling Industrial Conveyor Rust: The Key to Maximizing Efficiency and Profitability
Kind Reader, industrial conveyor rust can be a significant problem for many companies. Rust can develop on conveyor belts, rollers, and other components, causing them to degrade or fail prematurely. This can lead to costly downtime, lost productivity, and even safety hazards. It’s essential to understand the causes of rust on conveyor systems and take proactive measures to prevent it.
What is Industrial Conveyor Rust?
Industrial conveyor rust is the corrosion and decay of conveyor belts, rollers, chains, and other components of the industrial conveyor system. It can be caused by various factors, including exposure to moisture, chemicals, and high temperatures, as well as friction and wear and tear. Rust can cause serious damage to the conveyor system, leading to decreased efficiency, malfunction, and even accidents. Therefore, it is essential for industrial facilities to prevent and mitigate conveyor rust through regular maintenance, inspection, and cleaning.
The Dangers of Industrial Conveyor Rust
Industrial conveyor rust can pose a significant risk to the safety and productivity of the workplace. Here are some of the main dangers of conveyor rust:
| No | The Dangers of Industrial Conveyor Rust |
|---|---|
| 1 | Decreased efficiency and throughput of the conveyor system due to increased friction, jams, and slowdowns. |
| 2 | Increased maintenance and repair costs of the conveyor system due to the need for replacement of rusted components. |

| 4 | Increased risk of accidents and injuries due to malfunctioning conveyor components, such as broken chains, belts, and rollers. |
The Causes of Industrial Conveyor Rust
Industrial conveyor rust can occur due to various factors, either individually or in combination, including:
| No | The Causes of Industrial Conveyor Rust |
|---|---|
| 1 | Exposure to moisture and humidity, which can accelerate the oxidation and rusting of metal components. |
| 2 | Exposure to chemicals and corrosive substances, such as acids, salts, and detergents, which can erode the protective layer of metal components and promote rusting. |
| 3 | Exposure to high temperatures and thermal cycling, which can lead to the expansion and contraction of metal components and the formation of cracks and corrosion. |
| 4 | Friction and wear and tear, which can remove the protective layer of metal components and expose them to the elements, leading to rusting. |
Causes of Industrial Conveyor Rust
Rust on industrial conveyor systems is majorly caused by:
Poor Maintenance
Conveyors that are not well maintained tend to rust faster than those that are regularly serviced. When rollers are left to corrode, rust starts to form and eventually spread to the conveyor bed, chains, bearings and other parts. This can also lead to excessive noise and vibration from the conveyor components, which may impact the overall equipment effectiveness (OEE).
Humidity and Moisture
Humidity and moisture go hand in hand in creating rust on conveyor systems. Water on conveyor surfaces causes parts to corrode and rust over time. This can also lead to slippage and a general reduction in the lifespan of the conveyor components. Prevention measures should be put in place to avoid moisture from getting to the conveyors, including enclosure of critical components to reduce moisture and humidity exposure.
Chemical Exposure
Industrial conveyors that are exposed to industry chemicals like acids, salts, and alkaline substances are more likely to rust faster. The chemicals cause pitting on the metal surfaces, resulting in rust. This is particularly true for conveyors that are used in mining and chemical processing industries. It is, therefore, necessary to choose the right materials for such harsh environments, including coatings, metals and plastics.
Effects of Industrial Conveyor Rust
Rust on a conveyor system can lead to a series of problems, such as:
Failure of Conveyor Components
When rust is allowed to take over a conveyor, it can cause the components to fail prematurely, leading to unplanned downtime and production losses. Rust can cause rollers and joints to stick, which makes the conveyor difficult to operate and maintain.
Contamination of Products
Rust can easily contaminate products being conveyed and packaged on the conveyor system. These contaminants can be harmful to the health of the consumer and can lead to product recalls, which can be time-consuming and costly, as well as damaging the brand name. Rusty conveyor parts can also contaminate sensitive food products, leading to food poisoning and large fines for health code violations.
| No | Important Information |
|---|---|
| 1 | Rust on an industrial conveyor can cause it to malfunction. |
| 2 | Rust can also damage the products being transported and contaminate them. |
| 3 | Industrial conveyor rust can be prevented by using stainless steel or other materials that are resistant to corrosion. |
| 4 | Regular maintenance and inspection can prevent or detect rust before it becomes a problem. |
| 5 | If rust is detected, it should be treated immediately to prevent further damage. |
| 6 | Proper cleaning and lubrication can also help prevent rust and prolong the life of the conveyor. |
Corrosion prevention methods
Preventive measures and corrective actions can aid in reducing the rate of industrial conveyor rust and prevent future rust corrosion.
Choosing the right conveyor materials
One of the most effective ways to prevent rust from occurring is to build the conveyor using the right materials. In selecting the materials for the conveyor, the type of commodities transported, conveyor surroundings, temperature, and surface finish type must all be considered. Stainless steel and BHP’s Colorbond is a popular choice of conveyor material for many industries. Stainless steel is more corrosion-resistant compared to regular steel, whereas Colorbond has a protective coating for a rust-resistant surface finish.
Regular maintenance
For conveyors already in use, regular maintenance of moving parts such as rollers, sprockets, and bearings is required to avoid corrosion. Lubrication of moving parts and the use of rust preventative sprays and inhibitors will all help to keep the conveyor rust-free for longer.
Coatings and treatments
Protective coatings can be applied to the conveyor’s surface to shield it from potential rust. Powder coating, painting, and galvanising or hot-dipped galvanising are examples of such protective coatings. These coatings come in a variety of colors and thicknesses and can be tailor-fit to your specific conveyor requirements. Hot-dipped galvanizing is the process of dipping the conveyor parts into molten zinc to form a thick rust-resistant coating.
Prevention of Industrial Conveyor Rust
Prevention is always better than cure. The same principle applies to rust prevention. Regular maintenance and inspection of the conveyor system can help prevent rust formation. Facilities can add rust inhibitors to their inventory cleaning and maintenance materials, and these should be applied early, even before noticing signs of rust.
Regular cleaning and inspection
Conveyor rust prevention begins with regular cleaning and inspection of the system. Cleaning removes dirt and debris that could be a source of moisture and corrosion. If dirt and other materials are left unattended, they eventually accumulate and invite rust. Inspections can identify parts of the conveyor that show signs of rust, and these parts should be targeted for proper maintenance, repair, or replacement.
Rust inhibitors
Rust inhibitors prevent rust from forming. They can be applied as a coating that seals metal parts and protects them from moisture and humidity. It is important to select the appropriate rust preventive based on the conveyor system’s material and the corrosive factor present in the facility. Common rust inhibitors include oils, waxes, and acrylics, which form an invisible film that helps to preserve the metal surface.
Effective Rust Removal from Conveyor Belts
Removing rust from a conveyor belt is essential in maintaining continuous and uninterrupted production. Conveyor systems that have been running for years can still deliver optimal performance if the rust is removed effectively. Below are the methods used in removing rust from conveyor belts.
Manual rust removal
Manual rust removal is a common method of eliminating surface rust in industrial conveyor systems. The process involves using wire brushes, scrapers, and sandpaper to remove rust. However, manual rust removal can be time-consuming and labor-intensive for large conveyor systems. Additionally, it can be ineffective if the rust has already embedded deep into the metal.
Chemical rust removal
Chemical rust removal is another method of eliminating rust from a conveyor system. It involves using acid-based solutions to remove rust. The solution reacts with the rust and breaks it down, making it easier to remove. The conveyor belt should be washed with water after chemical rust removal to neutralize any remaining acids. It’s worth noting that these solutions can be toxic and must be handled using the appropriate protective gear.
Industrial rust removal
Industrial rust removal is the most effective method of removing rust from conveyor systems. Industrial rust removal uses electric rust removal machines to remove rust from the affected areas quickly. This technology has been widely embraced in many industries, and it is the most efficient method of removing rust from large conveyor systems.
Preventing Industrial Conveyor Rust
Prevention is always better than cure, and this truth very well applies to industrial conveyor rust, too. Preventing rust formation in the first place can save a lot of money, resources, and time in the long run as rust removal is a tedious and time-consuming task that halts daily operations.
Proper storage and maintenance
Just like any other industrial equipment, proper storage and maintenance of conveyor systems can go a long way in preventing rust formation. The conveyor should be kept in a dry and properly ventilated environment with an optimal temperature range to prevent excess moisture and humidity formation. Regular maintenance checks to detect any signs of rust formation should be performed, especially in regions with harsh weather or corrosion-inducing environments.
Use of rust-resistant materials and coatings
Another effective way to prevent industrial conveyor rust is by using rust-resistant materials and coatings during the conveyor’s creation and installation process. Stainless steel conveyors, for instance, have higher resistance to rust formation than plain carbon steel conveyors. Similarly, coatings like powder coating can also provide a layer of protection against the formation of rust.

Preventing Industrial Conveyor Rust with Regular Maintenance
A rusted conveyor belt has the potential to contaminate a product and cause downtime. Therefore, it is essential to conduct routine maintenance to identify any possible rust that may be occurring.
Conveyor Belt cleaning
Regular cleaning is essential to remove any moisture and contaminants on the conveyor belt, which can cause rust. It would help if you had a cleaning schedule based on usage. Accumulation of water on the conveyor belt or damp conditions can lead to moisture, which can cause rust and corrosion on the belt’s underside.
Check and replace damaged parts
Conveyor belt misalignment can cause damage to the belt’s edge, resulting in rust. To prevent rust, it is essential to check and replace damaged parts regularly. Additionally, any outdated or corroded components should be replaced with new ones that are designed to resist corrosion and rust.
Protecting Metal Conveyor Parts against Rust and Corrosion
Industrial conveyor parts made of metal are prone to rust and corrosion. They will eventually fail if left unprotected. Therefore, it is critical to take preventive measures to prolong the lifespan of the conveyor
Corrosion inhibitors
Corrosion inhibitors are substances that work by slowing down the corrosive action of water and air on metal. They are a perfect preventative measure to protect conveyor parts from corrosion and rust. A protective film is formed when the inhibitor is used by bonding with the metal surface, which prevents the contact of water and air with the metal surface, ultimately preventing rust formation.
Using Stainless Steel conveyor parts
Stainless steel is known to be rust-resistant and is, therefore, an excellent choice for conveyor parts. The chromium present in stainless steel forms a thin protective layer on the surface, which prevents rust and corrosion. Stainless steel is also resistant to high temperatures, making it an ideal material for parts that will be exposed to high temperatures.
| No | Corrosion Inhibitors | Stainless Steel Advantages |
|---|---|---|
| 1 | Form a protective barrier on the metal surface, which prevents water and air from coming in contact with it. | Resistant to rust and corrosion, Resistant to high temperatures. |
