Edge-carboxylated graphene nanosheets via ball milling PNAS
10/04/2012· Low-cost, high-yield production of graphene nanosheets (GNs) is essential for practical applications. We have achieved high yield of edge-selectively carboxylated graphite (ECG) by a simple ball milling of pristine graphite in the presence of dry ice. The resultant ECG is highly dispersable in various solvents to self-exfoliate into single- and few-layer (≤ 5 layers) GNs.
Optimization of mill performance by using
suffer from the procedure that is followed by the operator. Mill power Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner

Calculate and Select Ball Mill Ball Size for Optimum Grinding
In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.
Rod mills, how they function Mine Engineer.Com
Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. The rod charge must be maintained in good working condition, and broken and worn rods must be removed. Rod

Hydrogenation of Nanocrystalline Mg2Ni Alloy Prepared by
Nanocrystalline Mg2Ni powders produced by high energy ball milling (HEBM) were subjected to further severe plastic deformation by cold rolling (CR) or equal-channel angular pressing (ECAP). The microstructure of the alloys have been analysed by the Convolutional whole profile fitting method of the X-ray line profiles. The hydrogenation behavior has been studied by absorption kinetic measurements.
