Pulverization: In this method, collected solid waste is powdered by grinding machines, thereby changing its volume and physical characteristics. This pulverized solid waste is further disposed-off by land filling. This is costly technique.

in engineering, fine crushing of a solid material (to particles of less than 5 mm). Pulverization is used extensively for the concentration of mineral products in mining, as well as in metallurgy, the chemical industry, and construction. In essence pulverization is a process of formation of new surfaces. …

The reduction of materials such as stone, coal, or slag to a suitable size for their intended uses such as road building, concrete aggregate, or furnace firing.

Definition of pulverization “Pulverization” (comminution, crushing, grinding) is the process of applying an external force to a (solid) material of a certain size to destroy it and reduce it into pieces that are smaller than the original size.

Mechanically pulverizing coal into a fine powder enables it to be burned like a gas, thus allowing more efficient combustion. Transported by an air or an air/gas mixture, pulverized coal can be introduced directly into the boiler for combustion.

Pulverization or fine grinding is the ultra fine reduction of ore to liberate minerals for separation. Pulverizing includes multiple steps of crushing or grinding to reach the desired size.

i. In soil stabilization work, the separation of particles from each other rather than the breaking up of individual particles. Separation of the particles is the first step towards good dispersion of stabilization additives and moisture. Ref: Nelson.

A pulverizer or grinder is a mechanical device for the grinding of many different types of materials. For example, a pulverizer puritch is used to pulverize coal for combustion in the steam-generating furnaces of coal power plants.

Methods of pulverization include crushing, impact, and grinding; compressive strain and shear are very important in these processes. In essence pulverization is a process of formation of new surfaces.

In many cases pulverization is associated with chemical changes on the surface of the particles. The size distribution of particles in the products of pulverization is usually regular. The specific surface may serve as a measure of coarseness, since it is inversely proportional to the average size of the particles.

In addition to the pulverization of primary particles, wet pulverization also includes disintegration (= mechanical pulverization) and dispersion. In recent years, miniaturization of materials is often required, and not only pulverization but also disintegration and dispersion operations have become more and more important.

(* Disintegration (= mechanical pulverization) is one of the processes of dispersion. An external mechanical force is applied to agglomerated particles to loosen them almost without the formation of new particle surfaces and to reduce the size of agglomerated particles.)
