Marking a conveyor chain while moving
Q. Hi. I work for a lubricator mfgr. and we are researching a way to mark a conveyor chain while moving. The reason is to mark places of wear on the chain. As the other question we also want this mark to be removed but does not have to for awhile something that will fade away with in time less then a few months. Trying to find a source that we can spray or punch at a high speed where it well stick and can remain on for high temperatures for at least one time around for the chain. Thanks.

A. Look at a paint stick. It is like a large soft color crayon. Solvent will remove it when you no longer need it. A red magic marker fades quite fast in fluorescent lighting.

A. Use builders chalk (blue or red or white). Used in construction to snap chalk lines for cutting. You can use the bottle to "blow" a small amount on the chain. Withstands temp, and can be vacuumed or blown off easily.
Good Luck,

Conveyor chain is lurching
Q. Our conveyor chain lurches or surges. This causes daisy chained parts to pendulate and bump into one another. The chain is lightly loaded. The chain is properly lubed and tensioned. The take-up looks good. The dogs on the cat chain mesh nicely. I recently fitted an air cylinder to the floating conveyor drive, which helped somewhat. We have nearly 800 feet of I-beam with multiple turns and rises. Turn rollers all spin but some are badly worn. Turn bracing flexes during operation. Money is tight. HELP! Suggestions?

A. If the chain is "lurching", by which I assume you mean starting and stopping in spite of a continuous drive, then, somewhere in the system there is something which is flexing and releasing. Pay close attention, and you will find a weak brace, a cracked weld, a failing bearing, something of that sort.
