I will add to Jack's answer: While you still have to conduct media inspections, the required frequency is extended.

An example that I give in trainings is an average sized cast steel shot would have to be inspected every 8 hours of machine operation without classification. Adding a classifier stretches that out to every 40 hours of machine operation (5 times longer). As Jack said, it's done to make sure the classifier is operating properly.

Having a simple screen classifier really ups the game in media quality. Question: What do you currently do when your media fails inspection? Throw it away, or sent it out to be classified by a third party?
