Process:   The object of the process is to transform the pelletized concentrate into hardened pellets that can be used as blast furnace feed or direct reduction furnace feed. The transformation is achieved by the traveling grate and kiln. The traveling grate transports the pelletized concentrate through a series of controlled temperature zones to produce a preheated pellet of 800-900°C, which is dropped into the rotary kiln. The rotary kiln finishes the induration and is operated at 1200-1350°C. The indurated pellets are now dropped into an annular cooler where the pellets are cooled to a suitable temperature for transporting on a belt to load out facilities. The gases from the cooler are recycled to the kiln and the grate, resulting in the Grate-Kiln being the most energy efficient system for producing indurated pellets.

An iron ore plant contains many pieces of equipment. The major areas or process are the concentrator, balling, induration and handling. The concentrator is where the ore is ground to a fine size typically 80% – 45 micron powder and separated from other impurities by magnetic separation and flotation. The balling area is where the powdered ore is mixed with water, binder and rolled in rotating drums to create spherical balls. The induration area actually can be broken down into three areas: grate, kiln, cooler. The grate area is where the pellets are dried and the induration process is started. The pellets at this stage are becoming stable and can be dropped into the kiln without braking. The kiln is used to drive heat into the pellets to force the reaction throughout the pellet. In an effort to recoup all the heat that is currently in the pellet after the kiln, the pellets fall into a cooler. The Grate-Kiln System is basically a counter-flow heat exchanger; that is, the material (green pellets and indurated pellets) moves in a direction opposite to that of the process gas flow.

TRAPEZIUM MILL–the latest grinding equipment, with its own knowledge patents, have reached modern advanced level in the world.

Ball mill, milling ore machine  pelleting ore plant, ball grinder
ore processing globe mill is an efficient tool for grinding many materials into fine powder. Ball crusher is widely used in industrial production, one of the high-fine grinding machine. There are many of its kind, such as hand ball mill, horizontal ball mill, ball bearing, energy-saving ball mill, overflow-type ball mill, ceramic ball mill, ball girder and so on .Ball mill for grinding various ores for ore concentration and other materials are widely used in mineral processing, building materials and chemical industries can be divided into two kinds of dry and wet grinding methods. According to Pai mine in different ways, can be divided into two kinds of lattice type and overflow type. It is widely used in cement, silicate products, new building materials, refractories, chemical fertilizer, black and glass ceramics and other non-ferrous mineral production industry, for a variety of ores and other materials can be carried out dry grinding or wet grinding.
