Rotary Dryers and Corrosion Management
Heavy-duty rotary dryers have from little to no weaknesses when it comes to determining their longevity and robustness. However, corrosion is a common threat for any industrial equipment. Corrosion occurs due to a plethora of factors including chemical reactions, consequences of metal interacting with other substances, and reactions on the electrochemical level. We are all familiar with regular corrosion that occurs due to iron reacting to the presence of oxygen by producing iron oxide. Regardless of the corrosion cause, you will always want to avoid it and put heavy emphasis on prophylaxis and treatment of corrosion.
Drying in essence is removing liquid contents from various materials. This means that dryers are constantly interacting with liquids and water. In specific cases, using water is unavoidable due to the technological conditions of the process. Take palletization as an example where binder is a necessity that helps the material to form pellets in order to be prepared for further drying. Water contacts with various metal surfaces and enforces chemical reactions causing corrosion. Corrosion is basically micro damage inflicted to the equipment. Without immediate treatment, it can compromise the production process and cause long lasting downtimes. Corrosion also leads to heavier damage and often causes major malfunctions which in turn requires additional expenses for fixing and replacing malfunctioning equipment.
How to Prevent Corrosion
Corrosion is responsible for over $2 trillion U.S. of worldwide equipment expenses annually. Nearly a quarter of the expenses mentioned above could be easily prevented via proper prevention of corrosion. There are various methods that can help you to avoid corrosion and make your equipment more efficient.
Corrosion Resistant Materials are a Good Answer
Choosing the right material is the first step in preventing corrosion. There are metals that are simply better when it comes to resisting corrosion. Also some alloys may be resistant to corrosion while some metals in the alloy are less resistant. There are various materials of the construction that can make corrosion less of a factor. Strommashina prefers Stainless steels and alloys over other materials since their robustness and corrosion resistant are perfect for heavy-duty machinery.
Protect the Material
Additional protection can be applied in a form of various coatings that can prevent corrosion. Amongst the most efficient coatings you will definitely recognize some commonly used compounds like epoxy ester, urethane, acrylic, polymeric, latex, etc. All these coatings are isolating the material from the environment effectively preventing corrosion from occurring.
Constant Maintenance and Monitoring
In addition to the measures listed above, you should consider regular maintenance inspections focused solely on monitoring the condition of metal surfaces of your equipment.
Rotary dryers often interact intimately with the material that has certain level of wetness. This means that preventing clumping and accretion is one of the priorities in technical maintenance. The surface should be regularly inspected and you should look for any vulnerabilities of the material such as cracks, crevices, unevenness, and other surface flaws as these flaws may invite corrosion. Focus on removing accretion and fix cracks and crevices regularly in order to make corrosion less likely to occur. Try to exclude compounds and agents that may cause corrosion from your production process.
One of the reasons why Strommashina is one of the best manufacturers is that we use only those materials that can resist corrosion and require less maintenance in order to operate efficiently. If you want to guarantee longer lifespan of your equipment, consider working with us.
