应用吋， 磷石膏从生产线或者料场被输送到本发明的厂房内， 经过中和装置将 磷石膏与石灰搅拌混合后进入布料装置 6， 布料装置 6将混合后的磷石膏通过布 料装置 6上的输送带输送到厂房的远端， 在空中向布料装置 6侧边的空中抛撒， 抛撒幵的磷石膏与厂房内的热空气接触， 加速磷石膏水分的挥发， 同吋在抛撒 过程中， 风机 5对抛撒幵处于空中的磷石膏进行吹风， 更加加速磷石膏表面水分 的挥发， 挥发的水分通过由进风口 2和出风装置 7组成的气流通道排出厂房外部 ； 随着磷石膏的抛撒， 位于布料装置 6上的下料板幵始向进料一端移动， 阻挡磷 石膏向下料板后端的输送带运动而在下料板的位置向空中抛撒， 这样就将磷石 膏均匀抛撒并下落在地面层 1的表面位于隔墙 11附近； 落到地面的磷石膏在地面 层 1上受到地下热风道 12的加热， 靠近隔墙 11的磷石膏受到墙内热风道 10的加热 ， 加速磷石膏的水分挥发； 而本例中的自动取料装置 8采用单层取料的方式进行 取料， 也就是自动取料装置 8的取料机沿地面堆积的磷石膏的表层取料， 从厂房 的一端向另一端运动， 这样就能够保证获取的磷石膏含水率差别不大， 有利于 煅烧系统的稳定工作； 自动取料装置 8将获取的磷石膏送入预热炉进行预热， 进 一步去除磷石膏中的自由水分， 由于预热炉采用的是煅烧炉的排出热气， 因此 节省能源， 这样就完成了磷石膏煅烧预处理系统的工作过程。
