Rotary Kiln Maintenance

The rotary kiln is a valuable and important piece of equipment. While it may be a rough and tumble piece of hardware, it can be sensitive if not treated right. Because of that it needs to be maintained regularly and completely, with time taken to make sure that it is done right. If anything is missed, no matter how small it may seem at the time, it could cause greater problems later on, ranging from a misaligned cylinder to improper heating. As such, rotary kiln maintenance is an important process that needs to be done every six months or so in order to make sure that the kiln is operating well.

Rotary kiln maintenance is a simple process and can take as little as half an hour to an hour or two. It should be divided into three segments: Inspection, correcting, and ordering. Inspection is possibly the quickest part, as the entire assembly is inspected for potential issues. The inspection should go from the outside in, with an attempt to be as thorough as possible. While the kiln itself will be the target of most of the maintenance, make sure that the rest of the machine is in working condition with no rust or corrosion. Parts should be cleaned as necessary with problem parts noted.


Once the inspection is over, any needed correction can start. The obvious part is the kiln itself, as its alignment must be perfect. The alignment should be tested and if necessary adjusted until it is perfectly true and runs in a tight circle. It should be noted that even the slightest irregularity her means that parts will be ground well ahead of schedule, and could cause injury. Temperatures should have been checked and if off they must be adjusted as well, or the heating elements replaced in order to ensure that the kiln is operating at maximum efficiency. Any other debatable parts should be tested to make sure that they work up to the usual standards.


Ordering is the last and possibly most onerous part. All defective parts must be ordered as quickly as possible, with other parts ordered as before it looks like they will fail. While budget problems may prevent some ordering, any other attempts to block ordering may be a reason to discuss the problem with a supervisor. Bear in mind that not having the right parts on hand when parts go can create safety hazards or worse, but will cause the kiln to be shut down until they have been replaced, and that could cause serious money.


While it may sound onerous, rotary kiln maintenance is actually pretty simple and usually only takes a relatively short time. Operation time will affect how quickly the maintenance will take, but there are some major advantages; at the very least being able to tell how soon parts will need to be replaced is a major one, as well as being aware of potential problems before they become potential problems. A good, thorough inspection every six month should be enough for to make sure that your rotary kiln is up to snuff and working well, so make sure that you schedule some time to do so.
