the hardness of grinding media ball - how to choose balls
from the way the ball mill works. in the operation environment the ball mill is divided into two types: wet ball mill and dry ball mill. dry ball millwork has a strong corrosion so as the same wear-resistant grinding media ball the wear-resistant grinding media ball in the wet grinding efficiency is faster.

dec 28 2016 0183; 32;size (diameter) of the grinding media depends on the mill feed size (particle size of material supplied to the mill) and achieved degree of fineness (size and percentage of required class size material at the exit of a ball mill). usually the size of grinding media indicate in technical documentation for the mill.
media to media contact for rods mills is linear rather than point to point (as with balls) and are much heavier. the larger feed tends to separate rods at the feed end such that larger particles are preferentially abraded. this leads to a narrower size distribution and significantly less slime compared to ball mills.

charging and maintaining batch & continuous ball mills. smaller media = more contacts. since particle size reduction takes place when the material being ground is sandwiched between the media it is best to choose the smallest feasible grinding media combination as smaller media provide many more contacts than larger media.
sino grinding | grinding media
small grinding media has a larger grinding surface area generally chosen to help make smaller ore smaller. in some cases we find ourselves adjusting the ball size by the millimeter to approach optimization. our knowledge and control of the ball’s design and manufacturing allows the flexibility to make such changes. optimizing milling is part
comparison of grinding media—cylpebs versus balls
the two grinding media have diﬀerent surface area bulk density and contact mechanisms in grinding action. comparative tests were conducted using the two types of grinding media in a laboratory bond ball mill at various conditions of equality such as media mass size distribution surface area and input speciﬁc energy.
