2022.3.22 grinding tests were conducted in a smooth surface cylin-drical steel mill of 215 mm diameter and 190 mm long. The grinding media consisted of three different-sized steel balls having a density of 7.68 g/cm3 and diameters of 19.5, 38, and 50 mm. The Bond work index (Wi) of the quartz sample was determined based on two grinding tests.

Grinding in Ball Mills: Modeling and Process Control
There are three types of grinding media that are commonly used in ball mills: • steel and other metal balls; • metal cylindrical bodies called cylpebs; • ceramic balls with regular or high density. Steel and other metal balls are the most frequently used grinding media with sizes of the balls ranging from 10 to 150 mm in diameter [30].

Grinding Media Wear Rate Calculation in Ball Mill - 911
2017.4.29 Then in ball-wear formula (25), T = 6.9/K Log10 Da/Db; but from (29), K = Rt/Wt. Then T = 6.9Wt/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/6.9Wt are all known, and it is only necessary to solve for Db, the diameter of the balls to be added.
