The new two 3000 t/d clinker production lines is invested and completed in October, 2003, which totally costs 500 million CNY in China. It takes only 8 months from the foundation stone laying ceremony to the start-up situation. So it is also well known as “speed of electric current” for its short construction period. The two projects are both used the NSP rotary kiln production process and the advanced precalcining technology, supplied by Xinxiang Great Wall Machinery. All of the equipment are approved by the ISO9001:2008 Testing.
The big end cover and discharge system of the raw material mill adopt special streamline design, which reduces the air resistance and increases the effective volume, so it is easy to discharge and the yield of raw meal improves.
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.
The project confirms to the national industrial policy absolutely, fulfilling the demand of energy conservation and emission reduction and comprehensive utilization of resource. It is a project popularized and supported greatly by our country. Since the project is set up by Henan Meng Electric Group Cement Co., LTD, the equipment runs stably, with good stability and high production capacity, having strong demonstration effect.
