Rotary kiln is widely used in many production industries such as building material, metallurgy, chemistry and environment protection for the mechanical, physical and chemical disposal of solid materials by relying on its rotary cylinder equipment. The application of rotary kiln originates from cement production and the invention of rotary kiln promotes rapid development of cement industry and promotes people to research the application of rotary kiln, for this reason, rotary kiln is quickly and widely used in various industrial sectors and is increasingly important and becomes the core equipment in the production of relevant companies.
1.It has firm structure, stable operation and high production efficiency.
2. It has convenient usage and easy operation. Its energy consumption is reduced by 15% when compared with the same type of products.
3. The duration of new materials adopted by rotary kiln is far more than the same kinds of products.
4. It has stable performance and advanced structure, which has greatly improved its preheating effects.
5. It is equipped with advanced processing technology and high cost performance ratio.
6. It can be used for roasting cement and metal ore with controllable temperature, stable performance and wide application ranges.
The whole production process of cement can be summarized to ÔÇťtwo grindings and one calcinationÔÇŁ. Among them, ÔÇťone calcinationÔÇŁ refers to the technical process of calcining the raw materials prepared and ground to clinker under the high temperature of rotary kiln. In addition, in environment protection, developed countries have over 20 years of history in using cement kiln to incinerate hazardous waste and trash, which not only realizes reduction and harmless disposal of waste materials, but reuses the waste materials as fuel and saves pulverized coal.
Rotary dryer consist of a horizontally inclined rotating cylinder. Material is fed at one end and discharged at the other end. In direct-type rotary dryers, hot gases move through the cylinder in direct contact with the material, either with or against the direction of its flow. The cylinder is equipped with flights, which lift the material and shower it down through the hot gas stream.
