Gypsum powder production system and process
The invention relates to the technical field of comprehensive treatment of desulfurized gypsum, in particular to a gypsum powder production system and process. The system comprises a raw material bin, a rotary dryer, a fluidized bed furnace, a cooling heat exchanger, a ball mill and a powder bin which are sequentially connected, the discharging end of the rotary dryer is connected with the feeding end of a beater through a PU chain conveyor, the discharging end of the beater is connected with the feeding end of the fluidized bed furnace, and a homogenizing bin is further arranged between the ball mill and the powder bin; according to the process, through the processes of high-temperature pre-drying and medium-temperature calcination, the production system is high in heat efficiency, the product quality is good, meanwhile, the stability of the calcination process is guaranteed, and the problem of over-calcination or under-calcination is avoided; hard blocks possibly appearing in the drying and transporting process of the raw materials are scattered through scattering, so that the stability of the calcining procedure is facilitated; and through homogenization of the homogenization bin, the phase tends to be homogenized, so that the content of the semi-hydrated gypsum is increased, the physical properties of the gypsum powder are improved, and the product quality is improved.
本发明涉及脱硫石膏综合处理技术领域，具体涉及一种石膏粉生产系统及工艺。所述系统包括依次连接的原料仓、回转烘干机、沸腾炉、降温换热器、球磨机和粉仓，回转烘干机的出料端通过PU链式输送机连接打散机的进料端，打散机的出料端连接沸腾炉的进料端，球磨机和粉仓之间还设置有均化仓；所述工艺通过高温预烘干、中温煅烧的工艺，生产系统热效率高，产品质量好，同时保证了煅烧过程的稳定性，避免了过烧或欠烧问题的发生；通过打散将原料在烘干及运输过程中可能出现的硬块打散，以利于煅烧工序的稳定；通过均化仓均化，物相趋于均化，提高了半水石膏的含量，改善了石膏粉的物理性能，提高了产品质量。
