A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

A dust explosion is the rapid combustion of fine particles suspended in the air within an enclosed loion. Dust explosions can occur where any dispersed powdered combustible material is present in highenough concentrations in the atmosphere or other oxidizing gaseous medium, such as pure oxygen cases when fuel plays the role of a combustible material, the explosion is known as a fuelair

Isothermal experiments (a,b) were set at the equilibrium conditions and quenched. The goal was to accurately determine the phase assemblage, proportions, and major element chemistry. We used temperature oscillation (generally ± 10 °C) to grow coarser crystals with fewer inclusions, following Mills et al. (2011) and Mills and Glazner (2013).

The choice between wet and dry milling is, in general, unimportant in smallscale milling but is a major technical problem when largescale milling in the metallurgical industries is involved. On purely mechanical grounds it is difficult to see any great difference in fundamental principles between wet and dry milling, since dry milling may be regarded as wet milling with a fluid having the
