Henan Dengfeng Deng Electric Corporation Cement Plant is a 5000 t/d production line. The fixed asset is nearly 580 million CNY. The project is a national comprehensive utilization foundation for good demonstration, a planned project--11thFive-Year Plan made by Henan Province and an environmental friendly supporting project for its thermoelectricity company. 1,000,000 tons of industry wastes are reused in this cement plant producing. The total capacity can come to 2200000 t/y ordinary cement and 3000000 t/y Portland fly-ash cement.
As the measured data in the production of material shows, compared with traditional ball mills, the vertical roller mill can save electricity by more than 30% when producing one ton raw meal. The energy-saving effect is very significant. The liner of millstone and roller are surfaced with Boehler solder wire imported from Germany, having the characteristics of ultra-strong wear resistance, corrosion resistance and heat resistance, reducing the operating costs and prolonging the life time.
Through technology innovation, the calcination system of rotary kiln adopts the most advanced hydraulic gear wheel device at home and abroad, and adopts metering plunger pump with high measuring accuracy, high-precision flow speed control valve, contact graphite block sealing device and other domestic advanced technologies. It is easy to operate and its performance is reliable. The thermal regulation being stabilized and the operation rate being improved, compared with equipment with the same specifications, the operation rate increases by 10%, yield by 5%-10%, heat rate reduces by 15%.
Easy to operate, safe to use, stable and reliable performance; running continually, the production capacity is great.
