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 or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

BLACK BEAUTY ® blasting abrasives are a preferred alternative to silica sand. Silica sand can contain up to 99% free silica which has been found to cause silicosis, a sometimes fatal lung disease. BLACK BEAUTY ® abrasives are low dusting, chemically inert, contain less than 0.1% free silica and are not causally linked with any diseases, including silicosis.

The usual abrasive is simply silica sand, in a grit size between 30 and 60. (Glass work is done with grit size between 150 and 200) Keep in mind that silica sand is definitely NOT a good thing to inhale a lot of, nor is redwood sawdust, for that matter. Always use a dust mask, even if sandblasting within an enclosed cabinet.

The main mineral in silica sand is quartz that has tetrahedron structure as shown in Figure 4. At very high temperatures, each tetrahedron will separate from each other since the bond between the anion and the cation is not too strong (Schweigert, 2001) as shown in Figure 5. Nano silica resulted from alkali fusion has a good
