Ball hitting the liners is an event that can happen both in normal operation and during grind outs (run the mill without feed). Probability of this event happening is as follows: < 5% for a mill run "Perfectly" between 10 and 20 % for normal operation > 20% for a mill run poorly > 90% during grindouts.

Mill (grinding) Wikipedia

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
