Didn't realize we lose 2 tons of material per hour just from normal wear on the pump rings
Was reading an old maintenance report from 2013 my foreman dug up and saw the math on how much sand just gets chewed up and lost through normal pump ring gaps, has anyone else ever actually stopped to calculate their own hourly material loss from wear parts?

You ever actually time how long a set of carbide rings lasts before the gap opens up too much? I ran a similar calc on our plant's main slurry pumps a few years back and it was eye opening. We were losing almost a ton per shift just from normal ring wear, and that was on a good day. I started tracking it weekly with a feeler gauge and a logbook, and it helped me catch a bad batch of rings way earlier than usual because the loss rate jumped from 0.8 tons to 1.5 tons per hour overnight. Saved us a pretty penny on replacement costs when we caught it fast.

Tracked it with a timeline on a whiteboard next to the control panel. Each ring set got a row with its install date and a column for each weekly gap measurement. When I saw one set go from 0.030 to 0.045 in just three weeks, I knew something was off. That kind of hard data, like you found with @blair_torres70 your sudden jump from 0.8 to 1.5 tons, lets you pull the bad parts before they wreck your whole budget.
