Simply put, if you want to have the option of a super fine flour, then a burr grinding mill is a good choice. An impact mill, although will get you fine flour, won't produce flour that is super fine. For bread making, a finer texture is useful for whole grains, as this will help give the bread a lighter texture.

Most of the highgrade hematite iron ores are typically subjected to simple dry processes of crushing and classification to meet the size specifications required for direct shipping ore (DSO). This involves multistages of crushing and screening to obtain lump (− + mm) and fines (approximately − mm) products.

The hardness of the material governs the amount of penetration that can be achieved by the abrasive. For this reason, finer grit sized wheels are required to grind hard materials and soft materials are best ground with medium to coarse grit size wheels. For most efficient operation, the grade must be adjusted to suit the hardness of the material.

The bonding material does not cut during grinding operation. Its main function is to hold the grains together with varying degrees of strength. Standard grinding wheel bonds are vitrified, resinoid, silicate, shellac, rubber and metal. Vitrified bonds are used on more than 75 percent of all grinding wheels.

The coarser the grain, the larger the size of the material removed. Coarse grains are used for rapid stock removal where finish is not important. Higher numbers (such as 70, 100 and 180) are fine grit wheels. They are suitable for imparting fine finishes, for small areas of contact and for use with hard, brittle materials. Buying Bonds

Size reduction of solids involves creating smaller mass units from larger mass units of the same material. To bring this about, the larger mass units need to be subjected to stress by the application of force. Three types of force may be applied, compression, impact and shear. Compressive forces are generally used for the coarse crushing ...
