Method for producing sulfoaluminate cement and iron sulfoaluminate cement

Abstract

The invention provides a method for producing sulfoaluminate cement and iron sulfoaluminate cement; a shaft kiln is used for roasting sulfoaluminate cement clinker and iron sulfoaluminate cement clinker, and a new way is opened up for producing sulfate series and iron sulfoaluminate series special cement for shaft kiln cement plants in China under the condition of basically not increasing devices.

Description

technical field [0001] The invention relates to a production method of sulphoaluminate cement and iron sulphoaluminate cement, in particular to a roasting method of the cement clinker. Background technique [0002] Sulphoaluminate cement is a new cement series, and related standards (such as ZB11006-87, ZBQ11005-87) have been promulgated. Due to the characteristics of rapid hardening, early strength, and no shrinkage, Beijing series cement has become a best-selling product in the domestic market in recent years. Rotary kilns have been used for the roasting of clinker for such products, and there are very few manufacturers, so the supply exceeds demand. [0003] There are more than 5,000 shaft kiln cement factories in my country (including two types of ordinary shaft kiln and mechanical shaft kiln), which mainly produce five series of silicate cement products. In recent years, there have also been researches on the production of special cement such as road cement. Foreign c...
