Production method of phosphogypsum
The invention relates to the technical field of ardealite processing, and particularly discloses a production method of ardealite, which mainly comprises five steps: ardealite blocks are mashed, dried, ground, calcined, screened and ground, a dryer used for drying the ardealite blocks comprises a drying box body, a conveying track is arranged in the box body, and the ardealite blocks are conveyed to the drying box body through the conveying track. A plurality of evenly-distributed breathable films are arranged on the conveying rail at equal intervals, a protruding blocking plate is arranged in the middle of the conveying rail and provided with a rotatable splitter plate, and an air inlet pipe is arranged at the bottom end of the box body and extends out of the box body to be communicated with an air heater. The phosphogypsum blocks are flatly laid on the conveying rail through transmission of the conveying rail in the dryer, the phosphogypsum blocks cannot be stacked, the breathable film is arranged on the conveying rail so that hot air can flow from the bottom ends of the phosphogypsum blocks to the top ends of the phosphogypsum blocks, the splitter plate is matched with the blocking plate, half of the phosphogypsum blocks dried are turned over up and down, and the phosphogypsum blocks are dried. And rapid and comprehensive drying of the ardealite blocks is realized.
本申请涉及磷石膏加工技术领域，具体公开了一种磷石膏的生产方法，其主要包括5个步骤：对磷石膏块进行捣碎、烘干、研磨、煅烧、筛分、研磨，其中对磷石膏块烘干所使用的烘干机，包括烘干箱体，所述箱体中设有传送轨道，传送轨道上等距间隔设有若干块均匀分布的透气膜，传送轨道中间设有凸起阻隔板，凸起阻隔板设有可转动的分流板，箱体底端设有进风管，进风管延伸出箱体外与热风机连通。此烘干机中的传送轨道传动使得磷石膏块平铺传送轨道上，磷石膏块并不会堆叠，而且传送轨道上设有透气膜使得热气从磷石膏块底端流往顶端，分流板与阻隔板配合，将烘干到一半的磷石膏块进行上下翻面，实现对磷石膏块进行快速全面的烘干。
