The impact of attrition ball-mill pretreatment on food waste particle size, soluble chemical oxygen demand (SCOD), biochemical methane potential, and microbial community during anaerobic digestion was investigated based on milling speed and time. The uniformity of particle size improved with increasing milling speed and time. The SCOD of the pretreated samples increased to 4%, 7%, and 17% at

A process for providing a leady oxide having reduced levels of undesired metallic impurities such as, for example, bismuth and/or silver, comprises roasting the leady oxide to convert part to orthorhombic PbO, exposing the roasted leady oxide to particle size reduction so that the tetragonal PbO can be separated from the orthorhombic PbO fraction, and recovering the orthorhombic fraction

The core challenge to grinding a perfect ball is maintaining a precise radius from the tip of the nose back to the shank of the tool. To achieve this, a relief must be ground into the end of the tool, that leads out to an intersection of the outside diameter so that when it gets to the tangent point, creates a perfect radius.

The effect of ball size on the ORR activity of milled carbon catalysts was studied. • 0.5 mm balls decrease the size of final catalyst particles to under 1 μm. • Addition of PVP further decreased the catalyst particle size and increased ORR activity. • P max of 356 mW cm −2 and 52 mA cm −2 at 0.9 V reached in AEMFC by best catalyst.
