Flow of materials in rod mills as compared to ball mills ...
When the drum was used as a ball mill, Lucite balls, 1.9 cm diameter, were used as the stirring media. Lucite balls and rods (density of 1.25 g/cm 3) were purposely used to avoid the grinding action while the material is flowing through the drum.
Rod Mill - an overview | ScienceDirect Topics
The slurry generated from the rod mill is mixed with the slurry from the ball mill in a primary sump. The primary sump outlet stream is sent to the primary cyclone. The overflow from the primary cyclone goes to the secondary sump and the underflow is taken as a feed to the ball mill.
