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.
