Introduction: The ball mill is a tumbling mill that uses steel balls as grinding media. Ball mills can be used in wet or dry systems for bulk and continuous milling, and are most widely used in small or largescale ore beneficiation plant. Dry grinding: suitable for materials that react with water, such as building stones such as cement and marble.

In each test 15 balls out of a total ball load of 9000 g,, 126 balls (136 for HCCI balls), were marked and their weight loss recorded after a certain grinding time. The surface layer of each ball type was removed prior to conducting the marked ball wear tests by grinding for 30 hours in the porcelain mill.

When the ballmilling time is 24 h, CoCrW alloy powder is sintered after ball milling. The reinforcing phases are mainly in situ autogenerated M 6 C type carbides, which are blocky with the size of 110 μm. However, due to the relatively short milling time, the M 6 C carbides tended to be segregated.

After the biochar recovery of phosphorus (P), its role in eliminating Cr(VI) is uncertain. In this study, the ironsulfur biochar (Fe/SBC) was made by grinding Fe 0, S 0, and biochar with a ball ironsulfur biochar (PFe/SBC) was produced after recovering P from simulated wastewater and then used to remove Cr(VI) contamination in waterbodies.
