The invention belongs to the technical field of gypsum powder, and particularly relates to a calcining process for preparing gypsum powder, which comprises the following specific steps: selecting gypsum materials with irregular shapes and smaller volumes, putting the selected gypsum materials into a steam reaction kettle, introducing high-temperature steam into the steam reaction kettle to steam the gypsum materials, and then adding the gypsum materials into the steam reaction kettle; the preparation method comprises the following steps: steaming gypsum powder in a mixing pipeline, putting the steamed gypsum material in the open air for airing, weighing the aired gypsum material through a metering belt, feeding the gypsum material into a crusher for crushing, and crushing the gypsum material into powder meeting the calcining particle size requirement in the crusher. According to the continuous calcining device for the gypsum powder, not only can each powder be calcined, but also the gypsum powder can be continuously calcined, so that the calcining time is greatly shortened, and the calcining efficiency is improved.
本发明公开的属于石膏粉技术领域，具体为一种石膏粉制备用煅烧工艺，包括具体步骤如下：选取其形状不规则、体积较小的石膏料，将挑选出来的石膏料放入到蒸汽反应釜中，向蒸汽反应釜中通入高温蒸汽，以对石膏料进行蒸制，将蒸制后的石膏料放置于露天进行晾晒，通过计量皮带对晾晒后的石膏料进行称量，并送入到破碎机进行破碎，以在破碎机内破碎成符合煅烧粒径要求的粉体，本发明通过将石膏粉体和热气输送至经混合管道中进行混合，不仅能够实现对每粒粉体进行煅烧，还能实现对石膏粉体进行连续煅烧，从而会大大降低煅烧时间，提高了煅烧效率。
