Additionally, in ball mills grinding is primarily through cascading not cataracting (compared to an AG.SAG) so the slurry pool is not a factor unless density is high, which leads to viscosity issues. I have been told at a few sites I visited where the ball level is lower (e.g. 25%) that they operate at that level because they don't need the power.

The wear on the cement mill liner results from abrasion by the charge due to the dominance of shear energy absorption and to the impact resistance of the steel liner. For this mill, the shear energy absorption rate was 9.0 W/m along the first chamber of the mill compared to only 5.0 W/m for the second.

Presentation final.ppt - What is cement u2022Cement is a - Uesd Vertical Cement Mills For Sale. Aug 08, 2018· There are two well-known modes in which the ball charge moves inside the mill: cascading and cataracting.
Ball milling is the most widely applied method in grinding process, which crushes ores by the influence of medium in a cylindrical mill facilitated by continuous rotation. Generally, grinding medium has three types of motion states in the ball mill such as cascading, cataracting, and centrifuging.
menghasilkan enam kemungkinan mode gerak yaitu slipping, slumping, rolling, cascading, cataracting, dan centrifuging. Keenam mode tersebut sangat dipengaruhi oleh kecepatan sudut dari raw mill. Gambar 1. Contoh raw mill Selain kecepatan sudut raw mill, faktor lain yang mempengaruhi terjadinya mode-mode di atas yaitu jumlah
The cascading part of the charge varies more subtly with the inflection point in the cascading free surface becoming more angular and less rounded with increasing mill speed. We note that the relative strength of the cataracting to the cascading stream and the extent of direct liner impact by the cataracting stream are dependent on the liner ...

The rules that guide the design of a liner depend on the grinding mechanisms required for the specific mill. They can be classified either as impact/cataracting for very coarse to coarse grinding, cascading for coarse to medium …
A typical classification, suggested by Mellmann, includes three main motion regimes of the pebbles in such an equipment: slipping, cascading and cataracting, which are themselves divided into seven sub-regimes [8]. The slipping motion is characterized by a pebbles bed remaining at rest and slipping periodically or continuously from the wall of ...
Industrial tumbling mills typically operate in the high Froude range (cascading or cataracting) and exhibit a rich co-existence of flow regimes (Mellmann, 2001) that are bounded by non-linear surfaces as illustrated in Fig. 1. 1 The "rising en-masse" region is dense and follows closely the rotation of the drum.Flowing atop the …
