Method and equipment for producing building gypsum powder from industrial byproduct gypsum
The invention provides a method and equipment for producing building gypsum powder from industrial byproduct gypsum, which can increase the content of hemihydrate gypsum in a final product of buildinggypsum powder to be close to a theoretical limit value so as to greatly improve the quality of the building gypsum powder, and relates to the technical field of building gypsum powder production. Theinvention discloses a method for producing building gypsum powder by using byproduct gypsum. The method comprises the following steps: dehydrating and frying dehumidified and dried industrial byproduct gypsum powder for multiple times by using a plurality of powder frying devices of which the inner cavities are sequentially communicated through discharge holes of the powder frying devices and feed holes of the powder frying devices; wherein the feed ports of the powder frying devices are all arranged above powder frying heat exchange tubes of the powder frying devices, and the discharge portsof the powder frying devices are all arranged below the powder frying heat exchange tubes of the powder frying devices. The method can promote large-scale utilization of industrial by-product gypsum.
本发明是提供一种能够提高建筑石膏粉最终产品中半水石膏的含量，使其接近理论极限值，从而大幅提高建筑石膏粉的质量的工业副产石膏生产建筑石膏粉的方法以及设备，涉及建筑石膏粉生产技术领域。业副产石膏生产建筑石膏粉的方法，包括以下步骤：将除湿烘干后的工业副产石膏粉用多个通过炒粉装置出料口与炒粉装置进料口将内腔依次相连通的炒粉装置进行多次脱水炒制，从而生产建筑石膏粉熟料，其中，所述炒粉装置进料口均设置在炒粉装置的炒粉换热管上方，所述炒粉装置出料口均设置在炒粉装置的炒粉换热管下方。本发明可促进对工业副产石膏的大规模利用。
