Study on the impacts of media shapes on the performance of …
It was observed that grinding media shape (spherical, eclipsoids, cube, cylpebs, etc) can influence the performance of a tumbling mill. The media can directly affect the breakage rate, mill load behavior, power draw, and generally energy consumption. In other words, there is a strong relationship between the type of media …

Moreover, two models were developed to use ceramic balls instead of cylpebs as fine-grinding media in the wet tumbling mill based on the ball size and the ratio of the total mass of cylpebs. Cylpebs can be replaced by ceramic balls with 1.16–1.75 times the diameter of cylpebs, taking up only 76%–83% of the total weight of cylpebs.

QUESTION: CYLPEBS OR BALL?
We have repeatedly given evidence that the use of grinding balls in grinding material is more effective than the use of a cast iron cylpeb. Since we have a semi-industrial mill, we decided to conduct comparative tests.

Pebble Mill Grinding
Pebble Mill Grinding. Essentially tube mills and pebble mills may be considered as ball mills, the basic difference being that the ratio of length to diameter is greater. Usually the shell length is between 2 and 5 times the diameter. These mills are primarily used to grind various materials to 100 mesh and finer.
