New type dry process cement production line

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.
