Over the years, alternative procedures to the Bond grindability test have been proposed aiming to avoid the need for the standard mill or to reduce and simplify the grinding procedure. Some of them use the standard mill, while others are based on a nonstandard mill or computation techniques. Therefore, papers targeting to propose a better alternative claim to improve validity, to reduce test ...

A mechanical rectifier is a device for converting alternating current (AC) to direct current (DC) by means of mechanically operated switches. The bestknown type is the commutator, which is an integral part of a DC dynamo, but before solidstate devices became available, independent mechanical rectifiers were used for certain applications. Before the invention of semiconductors, rectification ...

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].

A rectifier is an electronic device that converts an alternating current into a direct current by using one or more PN junction diodes. A diode behaves as a oneway valve that allows current to flow in a single direction. This process is known as rectification. A rectifier can take the shape of several physical forms such as solidstate diodes ...
