The ball mill is a key piece of equipment for grinding crushed materials, and is widely used in production of powders such as cement, silicates, refractory material, and glass ceramics, as well as for ore dressing of both ferrous and nonferrous metals. Ball mills can grind wet or dry and can be continuous or batch type mills.
It is also ideal for universal fine grinding of inorganic and organic samples, dry or in suspension as well as for preparation and homogenization of pastes and creams on a laboratory scale. ) Disk Mills. Disk Mills are specifically designed for the size reduction for materials in the medium particle size range.

WSDOT is investigating the following pavement grinding options to reduce the noise from older concrete pavements. Next Generation Concrete Surface (NGCS) is a new grinding method that has produced the quietest concrete pavements in other states. Conventional diamond grinding (CDG) reduces noise from older concrete pavements.
Mills and Grinders. In a laboratory, most materials required for sampling are, in practice, nonhomogeneous mixtures. The best method of obtaining a small representative sample of the nonuniform whole is to take a quantity of the material large enough to be compositionally representative and reduce it to a fine homogeneous powder.
