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.

Free electrons are repelled to the side of the ball further away from the negatively charged rod. This leaves a positive charge on the side of the ball closer to the negatively charged rod. Since the induced positive charge on the ball is closer to the negatively charged rod, than the induced negative charge on the ball the attractive force is ...

• Static indentation tests: A ball, cone, or pyramid is forced into the sur-face of the metal being tested. The relationship of load to the area or depth of indentation is the measure of hardness, such as in Brinell, Knoop, Rockwell, and Vickers hardness tests. • Rebound tests: An object of standard mass and dimensions is bounced

The efficiency of a mill is directly proportional to power consumption (for equal coarseness of the initial material and the product). Material with a particle size of up to 30 mm is handled by ball and rod mills; self-grinding mills are suitable for particle sizes up to 300 mm. The particle size of the product may be less than 0.04 mm.
