New type dry process cement production line means utilizing the outside kiln precalcining technology as new type process

New type dry process cement production line means utilizing the outside kiln precalcining technology as new type process to produce cement. The production takes suspension preheater and outside kiln precalcining technology as the core, taking advantage of new type raw material and fuel homogenization and energy-saving grinding technology and equipment, utilizing the computer distributed control system in the whole line, so as to realize the automation, high efficiency, best quality, low energy consumption, and environmental protection in the process of cement production.

New type dry process cement production technology began to develop since 1950s. Till now, the production equipment ratio of new type dry process cement and clinker, featured with suspension preheater and precalcining technology, has taken up 95% in Japan, Germany and such developed countries. The first set suspension preheater and precalcining kiln were put into production in 1976. The advantages of the technology are as follows:

1.     Transferring heat rapidly;

2.     High heat efficiency;

3.     Having larger production per unit volume compared with wet process cement;

4.     Low heat consumption

The development of cement production technology have experienced the following stages: During the first stage, from 1950s to the early 1970s, the suspension preheating technology emerged and developed; During the second stage, in the early 1970s, the precalcining technology emerged and developed; During the third stage, new type dry process cement production line has been developing very rapidly.
