4.2 13m cement mill with a new process of double closed cycle grinding system, PC32.5 cement production reached more than 350t/h, this data set a new record in China.

Cement is the leading industry of xinjiang building materials industry, and the total industrial output value accounts for more than 1/3 of the building materials industry. With the advance of "the 12th five-year plan" and the positive response to the national "energy-saving micro-discharge, energy-saving and intensive", the cement industry has put forward higher requirements for the development of the outdated production technology. For the construction of tianshan stock kuqa cement grinding station, we must find out a technical route suitable for the situation of kuqa grinding station instead of the traditional grinding road. Therefore, tianshan co., ltd. established a technical renovation group of kuqa grinding station headed by Yang zhaoqi, vice President of the group.

Tianshan stock kuqa cement factory

Technical innovation group summarizes the existing domestic grinding technology, at the same time a large number of domestic and foreign literature on grinding technology, mutual discussion, analysis and summary of each cement enterprise advanced grinding technology, learn from each other. At present, it is generally accepted that large roller mill is a relatively advanced technology in the cement grinding industry. Tianshan co., ltd. is also a large-scale cement production enterprise affiliated to sinoma international, which owns abundant cement production technology. A large number of people hold conservative opinions on the technical reform of kuqa cement grinding station, believing that the grinding process at the present stage is quite perfect and there is no possibility to increase production. After the demonstration of all parties of the group, combining with the existing technology, the technical reform plan is determined. However, on the basis of summarizing the experience at home and abroad, Yang zhaoqi believed that there was still the possibility of raising production and reported it to the group. Although the renovation project has started construction, Yang zhaoqi gathered members of the technical renovation team, chengdu cement design and research institute, and yancheng jida machinery equipment manufacturing co., ltd. to discuss together, and found that there are still some deficiencies in the existing design. According to yancheng jeddah mechanical grinding reform experience for many years, think again after material through roller press broken by the v-shaped classifier will have 40% of more than 80 mu m sieve into the cement mill, will lead to the occurrence of a grinding, in order to avoid the phenomenon of grinding, that after the selection of the V of fine powder and then to choose powder, will eventually in the coarse powder directly into the mill, improve the efficiency of the grinding mill, and also improves the ZongGeTai when production.

Yang zhaoqi with the new grinding change program, and the technical change team, yancheng jida machinery manufacturing co., ltd. in conjunction with the chengdu cement design and research institute of experts to demonstrate that the feasibility of the process is high, improve the production is obvious, can implement the new double closed circuit powder grinding process. After multiple discussions with other members of the group, Yang zhaoqi finally determined the new process plan and suspended the current plan. At the same time, Yang zhaoqi led the technical reform team, rushing about in other domestic cement enterprises equipment manufacturers, jointly discuss the new grinding process plan, and the cement industry authorities jointly discuss the feasibility of the new cement grinding double closed circuit system. On the premise of comprehensive demonstration, Yang zhaoqi adjusted the original grinding process, increased investment, and changed the original double-closed circuit system into the new double-closed circuit grinding system.

 The process after technical renovation

　　Perhaps, is to have the opportunity to prepare the people, in the cement grinding boot, and fully demonstrated Yang Zhaoqi bold ideas, grinding system within one week when output reached 350 tons/hour, has jumped to an all-time high of cement grinding system, cement at the same time fully meet the technical specifications of the relevant regulations, to improve the market competitiveness of the cement products. In response to national policies at the same time, to achieve the reduction of consumption, but also to achieve a win-win effect of increasing production. This new grinding technology will also be applied in other cement grinding plants, to serve the cement production industry, at the same time the road of technical reform is still very long, we need to continue to explore, continue to innovate, and create a new high.
