In recent years, the comprehensive utilization of resources in the cement industry has made a major breakthrough, and the wastes consumed by the cement industry account for more than 80% of the total solid waste utilization in the country. By adopting less clinker, micro-powder and low-cost cement production technology, the cement industry can consume the fly ash, slag, coal gangue and other industrial wastes produced by electric power, metallurgy and coal industry to the utmost extent. Fly ash dryers are widely used in construction, building materials, water conservancy and other departments. Environmental protection and improvement are gaining more and more attention, and the application of fly ash dryers is becoming more and more extensive. Saving energy and reducing consumption is an important condition for building a conservation-oriented society and creating a harmonious society. It is also the most effective way for cement companies to increase their profits.
The fly ash drying equipment is designed for the characteristics that the initial moisture of fly ash is higher than other materials, the specific gravity is smaller than other materials, and the fluidity changes during the drying process. It has compact structure and small floor space. It is one-half of the same output single-tube drying area. It has reliable work, low energy consumption, high thermal efficiency, good material drying effect, easy automatic control and less operators. The wide application of fly ash dryer solves the problem of fly ash pollution and disposal problems, and also turns fly ash into waste, which increases economic benefits and has a promising market prospect.
Compared with other drying equipment, the fly ash dryer has large production capacity and can be operated continuously; the structure is simple, the operation is convenient; the fault is low, the maintenance cost is low; the scope of application is wide, the fluid resistance is small, and it can be used to dry the granular material. It is also advantageous for those materials with high adhesion; the operation flexibility is large, the flow rate of the product allowed in the production has a large fluctuation range, and the quality of the product is not affected; the cleaning is easy.
