Ball Mill Explained - saVRee
If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to …
Studies Show Snags to Mill Optimization | E & MJ
At Eagle, the ball milling circuit starts with a crushing plant and ends with a 12.7-mm screen. "The ball mill is 3.20 m diameter and 4.88 m long," the study said. The discharge typically contains "negligible +12.7-mm material." At the time, "tonnage was 45 metric tons per hour (mt/h), and mill power draw was 709 kW," the study said.

Optimization of mill performance by using
There is no data related to liner design such as the toe and shoulder regions. Production is disrupted for the duration of the procedure: grind-out, mill stoppage, mill start-up and the transition period to steady state. Stresses, generated in the ball charge, increase, which may result in spalling of balls and blocking the grate discharge.
