الحصول على السعرCommon types of grinding mills include Ball Mills and Rod Mills. This includes all rotating mills with heavy grinding media loads. This article focuses on ball and rod mills excluding SAG and AG mills. Although their concepts are very similar, they are not discussed here. Photographs of a glass ended laboratory ball mill show action of ball mass within the mill.
الحصول على السعرThe method by which the first iron workers in ancient time produced a sponge and incoherent mass by reduction the iron ore with the hot coals of their small bonfires has already been described. Because of its appearance, and with the passing of time, man came to call it sponge iron. This production contained metallic iron, ferrous oxide which had hot been reduced, slag and impurities and only ...
الحصول على السعرThough most mining wastes, such as overburden, are inert solid materials, the industry also generates waste that is toxic in nature. Some of these toxic are inherently present in the ore, for
الحصول على السعرA ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati

الحصول على السعرCast iron is basically an alloy of iron and carbon and is obtained by remelting pig iron with coke, limestone and steel scrap in a furnace known as cupola. The carbon content in cast iron varies from % to %. It also contains small amounts of silicon, manganese, phosphorus and sulphur in form of impurities elements.
الحصول على السعرWrought iron is an iron alloy with a very low carbon (less than %) content in contrast to cast iron (% to 4%). It is a semifused mass of iron with fibrous slag inclusions (up to 2% by weight), which gives it a "grain" resembling wood that is visible when it is etched or bent to the point of failure. Wrought iron is tough, malleable, ductile, corrosionresistant and easily welded.
