Operation and Elements of a Closed-Circuit Ball Mill System . Cement ball mills typically have two grinding chambers. The first chamber is filled with larger diameter grinding media andlined with lifting liners . The first chamber coarse-grinds the feed material and prepares it for the second chamber. The second chamber is the fine grinding ...

Clinker grinding technology is the most energy-intensive process in cement manufacturing. Traditionally, it was treated as "low on technology" and "high on energy" as grinding circuits use more than 60 per cent of total energy consumed and account for most of the manufacturing cost. ... + Lower SEEC in compare with ball mill + Stable …

The ball motion in the mill was simulated via discrete element method (DEM). Our results show that steel balls achieved faster breakage of clinker into finer particles than alumina balls, which was explained by the higher total–mean energy dissipation rates of the steel balls. The PSD became finer as smaller balls were used.

The objective of this paper was to evaluate the final granulometric distribution of the clinker in a ball mill operating in different rotation speeds, varying the …
