Pudong new district, Shanghai, China.
Four types of cement were made: on one hand, intergrinding PG and reagent gypsum with the raw mix to obtain a clinker with 2% SO 3 content, which was burning at 1285 °C for 1 h and then cooling by air. On the other hand, by grinding PG and the reagent gypsum (control sample) added directly to the clinker.
Gypsum grinding process The crushed gypsum is sent to a ball mill for grinding until 90% of it is less than 149 μm (100 mesh). The ground gypsum powder leaves the mill in the form of airflow and is collected in the cyclone separator. The process of grinding Ball mill The ball mill is mainly a machine for dry or wet grinding of the crushed gypsum.
