Description

Technical field [0001] The invention relates to an internally fired building gypsum manufacturing process. Background technique [0002] With the development of the construction gypsum industry, the production process of construction gypsum has also appeared in different forms. From the earliest frying pan to the external firing rotary kiln, and then to the fluidized fluidized furnace, the output is increasing and the quality requirements are becoming more and more stringent. Contents of the invention [0003] In order to overcome the shortcoming of low thermal efficiency of the existing externally fired rotary kiln method, the present invention provides an internally fired building gypsum manufacturing process. The technical solution adopted by the present invention to solve its technical problems is: process steps are as follows: [0004] Step 1: selecting materials, using natural gypsum, or chemical gypsum, or a mixture of natural gypsum and chemical gypsum as raw mat...
