Evolution, progress, identity. I have several flat faced and plated examples Cameron hand made for Pros in the late '90's. They are smooth faced and any ultra fine milling disappears with the finish. Directly opposite from same era putters and the trend today.
The feed samples of X, Y, and Z iron ores were ground in the BBM (ball mill refers to a BBM of size 300 mm × 300 mm with smooth liners) to identify the PSD, BWI, and RT of each ore. Grinding experiments were conducted according to Bond's standard test procedure [].For each iron ore sample, the RT taken to produce 250% circulating load in the BBM was measured by a new method.
