Critical Speed and a Grinding Ball. For the ball mill to work properly, it must reach critical speed. This is the speed at which the grinding balls start to spin along the ball mills' interior walls. If the ball mill does not reach critical speed, the grinding balls will stay at the bottom. They won't be able to grind the material properly.

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 adsorption, part of adsorbed Cr(VI) was reduced by Fe(II) and then stabilized by Fe(III) in the form of amorphous Cr x Fe 1x (OH) 3 on the composite surface. All the results demonstrate that novel ballmilled biochar/iron oxide composites can be used as an effective adsorbent to remove Cr(VI) from water.
