subject: Rotary Kiln Is Indispensible In Industry [print this page] Our cement plant mainly contains cement mill, cement rotary kiln and etc, which are the key equipments to assemble large-scale cement production line, they mainly used in the mass production of building materials like cement, concrete, and etc.
Concrete, the general term of integral engineering composition material, formed by aggregate glue. Generally speaking, by proportionally mixing with cement as cementing material, sand, stone as aggregate and water (with or without admixtures and additive), after mixing, molding, and conserving, it can get the concrete, also known as ordinary concrete, which is widely used in civil engineering.
Rotary kiln is also called rotary calcining kiln, it belongs to building material equipment, and can be divided into cement kiln, metallurgy chemical kiln and lime rotary kiln according to different materials.
According to the exterior, rotary kiln can be pided into altered diameter rotary kiln and drift diameter rotary kiln; according to the usage, it can be pided into cement rotary kiln, clay-grain rotary kiln, kaoline rotary kiln, lime rotary kiln; according to energy supply, it can be pided into gas rotary kiln, Coal-fired rotary kiln and Mixed fuel rotary kiln.
1. The technical performance and running situation of rotary kiln, to a great extent, decide the quality, quantity and cost of Enterprise Products. If there is big kiln turning, there is a million. This folk rhyme is a vivid description of the importance of rotary kiln in production process.
2. As to the application of rotary kiln, the cement industry owns the most numerous rotary kilns in production. The whole cement process flow can be generalized as Two Whet A Burn. A burn refers to the process flow that calcining grinded raw materials to clinker under the high temperature of rotary kiln. So, rotary kiln is the host machine in cement production, it usually called as the heart of cement plant.
3. In building material industry, besides cement clinker, rotary kiln is also used to calcined clay, limestone, and drying slag; in the producing of fireproofing materials, raw materials calcined by rotary kiln has the features of stable size, increased strength, and easy to reshaping.
4. In chemical industry, rotary kiln is used to produce soda, calcine phosphatic fertilizer and barium sulphide. In the 1960 s, the American Lapple invented the new technology to produce phosphoric acid with rotary kiln. This new technology has the advantages of low energy consumption, low electric power consumption, none sulfuric acid and can use low grade phosphorite.
Rotary dryer is used to remove moisture from material using hot gases to heat the feed material and to evaporate the water. Rotary Dryers are suitable for drying wide range of materials continuously because of its ability to process material having considerable variation in size and composition. Rotary dryer is mainly for dealing with material in large quantities. As reliable operation, operating flexibility, adaptability and large capacity, this dryer is widely used in metallurgy, building materials, food, light industry, chemical industry, coal, medicine and mining industries. It plays a significant and non-substitutable role in these industries.
