Autogenous grinding tests were run in a 10 ft x 4 ft Rockcyl mill. The principle of prepared feed and media was utilized to determine how coarse a feed could be commercially fed to a rock mill. Secondary rock milling was expanded toward the particle sizes of primary milling while still utilizing the practices of secondary milling.
Rock abrasion in autogenous milling distribution of rock sizes, mill speed and lifter configuration. Tests were conducted on pebbles which had been rounded in the mill. It was demonstrated that abrasion rate per unit mass increases significantly with rock mass. A simple laboratory test for rock hardness was shown to be correlated to
Autogenous Mills operate, mechanically, similar to the ball mill. They differ in the media they use to break or grind the ore. Autogenous Mills use large particles of ore instead of steel or other balls for grinding media. Autogenous mills use large pieces of ore as grinding media. The grinding is facilitated in autogenous mills by attrition
