The finely crushed material has the characteristics of large specific surface area, high surface activity, high chemical reaction speed, high solubility, low sintering temperature, high strength after sintering, strong filling capacity, good absorptivity and the like. For example, high definition kinescope can be manufactured by using high-fineness graphite; the dosage and absorbability of the medicament can be changed by the refinement of the particles: varying the particle size can vary the hiding power of the pigment; the strength and toughness of the ceramic can be improved by using the fine powder to manufacture the ceramic; the coal blocks are ground into powder and then combusted, so that the heat efficiency of the coal blocks can be improved; the iron powder is extracted from the ground iron ore and then smelted, so that the quality of the molten iron can be improved, and the energy consumption can be reduced; the quality of float glass can be obviously improved by improving the fineness and the purity of the silica sand; the properties of the original material can be changed by changing the granularity of the material, and the like. All these examples show that it is important to control and improve the powder quality, and an important way to accomplish these tasks is to develop an advanced powder manufacturing system, one of the key devices in the system is the pulverizer.
