What Fields That Rotary Kiln Is Used In
Among many production industries such as building material
, metallurgy, chemical industry environmental protection, the widely used turning circle equipment which process solid material with mechanical, physical or chemical is called rotary kiln.
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.
There are two main categories of cement rotary kiln: one is rotary kiln, whose kiln shell lies horizontally with slight slope, and can do rotary movement; the other one is called shaft kiln, whose kiln shell is set vertically without rotating. It is composed by cylinder, bearing devices with gear wheel, gear, movable kiln head, sealing device and pulverized coal injection pipe device. Cement rotary kiln body has a certain inclined angle with horizontal, the whole body is supported by roller device with catch wheel to control kiln body moving; besides main drive, the transmission system is also set auxiliary gear keeping rotating when main power source break to prevent bending kiln; both head and tail of kiln adopt advanced technology to ensure sealing reliability.
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. And to be more specific, it is as follows:
(1) Its technical performance and operation determine the quality, output and cost of the product to a large extent. The folk As long as the rotary kiln moves, there are thousands and thousands of things is a vivid description of the importance of rotary kiln in production.
(2) In the application fields of rotary kilns, the number of cement industry is the largest. The entire production process of cement can be summarized as "two grinding and one burning", of which "one burning" is the process to calcine the prepared raw material to clinker under high temperature in rotary kiln. Therefore, rotary kiln is the principal equipment in cement production, and it is commonly known as the "heart" of the cement plant.
(3) In the building material industry, apart from the calcination of cement clinker, rotary kiln is also used for clay and limestone calcination and slag drying; in the production of refractories, using rotary kiln to calcine raw materials can make it dimensionally stable, strength increased , and then process and moulding can be easier.
(4) In ore beneficiation process, rotary kiln roasts lean iron ore in a magnetic way, so that the ore changes from original weak magnetic to strong magnetic in order to facilitate magnetic separation.
