Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). …
They were introduced in 1993 at Buzzi Unicem's Trino plant in Italy with the purpose of reducing energy costs. Details of the operating principle of Horomill ® as compared to HPGR and vertical roller mills are given by Cordonnier (1994) and Buzzi (1997).The energy saving of this mill is claimed to be similar to that of HPGR and …
Vertical roller mills and ball mills represent two clearly distinct technologies. However, with proper adjustments to the operational parameters of the vertical roller mill almost identical cement properties can be achieved by the two mills that satisfy the cement user's demands.Nevertheless, the two types of mills have their distinctive merits.
The other major repairs that take place on ball mills are to replace the liners and diaphragms and on a VRM to replace (or turn) the rollers and replace the table. The liners on a ball mill generally last up to 5 years in the first chamber and as long as 8 years in the second chamber and therefore are infrequently changed.
