semidry/semiwet or wet depending on how the raw material is handled before being fed to the kiln. Moisture content of the raw materials (ranging from 3% for hard limestone to over 20% for soft limestones such as chalk) is the main criterion for governing the process used. In the dry process the feed material is in a dry, powdered form.

Then in ballwear formula (25), T = /K Log10 Da/Db; but from (29), K = Rt/Wt. Then T = /Rt Log10 Da/Db T is 1 day, Wt is the original weight of the ball charge, and Rt is the ball wear for one day. Then Log10 Da/Db = Rt/ are all known, and it is only necessary to solve for Db, the diameter of the balls to be added.
