Application of cement clinker vertical roller mill in cement plant

Cement vertical roller mill is a new type of vertical roller mill developed by our company for the final grinding process of cement clinker. It integrates grinding, drying and classification. Compared with traditional mills, its great advantage lies in low energy consumption. : The average power consumption is lower than 30kwh / t. Because of the advantages of high grinding efficiency, large drying capacity, stable product fineness, and low operating costs, the equipment has become a new generation of new environmentally friendly cement grinding equipment. Cement vertical roller mills have various varieties and complete specifications. According to different project scales, they can meet the production needs of 1000-7000 tons of cement clinker per day.

 

Cement enterprises are pided into four types according to production technology: cement plants, clinker plants, grinding stations and preparation plants. Grinding stations include: enterprises of cement grinding, cement homogenization and preparation, cement packaging and bulk production processes. Cement clinker vertical roller mill is mainly used for powder processing of various slag, limestone, barite and other minerals. The use of fine slag powder is becoming increasingly common, and fly ash will also be used in its fine powder form. Therefore, whenever a new grinding station is built, it is necessary to consider setting up a fine slag powder storage and a slag measuring scale in front of the cement grinding tail and the cement storage, so as to match with the out-grinding cement and enter the cement storage after homogenization. This can not only improve the quality of cement, but also greatly increase the cement output of the grinding station. Cement clinker vertical roller mill is the core equipment of cement grinding station. In recent years, product quality, equipment technology, technology and other aspects have been improved. To some extent, the problems encountered in the construction of cement grinding station have been solved. The location of the grinding station is very important. Due to the particularity of the vertical roller mill and its supporting facilities, we help users to survey the site for free, produce the process flow, guide the installation on site, and train equipment operation. Shuguang Heavy Machinery's vertical roller mill technical staff suggested that, generally, a cement clinker production line should be established near the raw material mining area, and a cement grinding station should be established near large and medium cities, that is, near the cement sales market, so that transportation costs can be reduced. If the clinker production line is built near the city, since about 1.6 tons of raw material are needed per ton of clinker, the transportation cost will need to be increased by 60%. Conversely, if the grinding station and the clinker production line are built near the raw material mining area, since most of the mixed materials are waste residues generated by the city, these mixed materials must be transported to a cement plant built near the mining area, and then ground into cement. Transportation to cities for use increases transportation costs.

 

Cement clinker vertical roller mill is the main equipment in the process of cement grinding station. Cement clinker vertical grinding has strong crushing strength, high crushing efficiency, and good operation stability. To a certain extent, reduce power consumption or increase system output, to some extent, address concerns such as low output and unstable operation of cement enterprises. In addition, in terms of process flow, in fact, compared with closed-circuit grinding, open-circuit grinding mills are only investment-saving and easy to maintain and manage. However, the closed-circuit mill is easy to adjust and has better adaptability to changes in raw material quality and moisture. In the new grinding station, when the clinker is purchased from several clinker manufacturers, the grindability of the clinker must be different. At this time, the output of the closed-circuit mill and the fineness of the grinding cement are not changed because it is easy to adjust. Some experts recommending the use of open-circuit mills believe that open-circuit mills have a wider particle size distribution than closed-circuit mills because of their wider particle size distribution, so the standard consistency requires less water, and concrete mixing stations are welcome. Which method is used, the cement plant can choose according to the actual situation. The vertical grinding of cement clinker does not have strict requirements on both processes.
